The graph of f(x)= x^2 is transformed by a vertical reflection, then a horizontal compression by a factor of 2, then a horizontal translation 3 units to the right, and finally a vertical translation of 5 units up.

-What is the equation of the transformed function?

-What is the domain and range of the transformed function?

Answers

Answer 1

If g(x) is the transformed function, then

   [tex]g(x) = - f\big( ~2 (x-3)~ \big) + 5[/tex]

or

   [tex]g(x) = - \big( ~2 (x-3)~ \big)^2 + 5[/tex]

The domain is still all real numbers, (-infty, infty).


The range is (-infty, 5], since it was reflected vertically and then translated up by 5 units.

Answers

The length of the shortest altitude of the triangles is 15 units by using Heron’s formula.

We have, The sides of a triangle have lengths of 15, 20, and 25.

To find, The length of the shortest altitude of the triangle.

Steps to solve the problem:

Let us assume that the length of the b is h.According to the property of triangles, the area of the triangle can be calculated as:

Area = 1/2 * base * height

We can choose any side as the base of the triangle, let us assume that 20 is the base of the triangle, and its corresponding height is h.

Area of the triangle = 1/2 * 20 * h ⇒ 10h

Using Heron’s formula, the area of the triangle can be calculated as:

A = √(s(s-a)(s-b)(s-c))

Where a, b, and c are the sides of the triangle, and s is the semi-perimeter of the triangle.

According to the given problem, the sides of the triangle are 15, 20, and 25.

s = (a + b + c)/2

= (15 + 20 + 25)/2

= 30

Therefore, the area of the triangle can be calculated as:

A = √(30(30-15)(30-20)(30-25))

= √(30*15*10*5)

= 150 sq. units

Therefore, we can write the formula for the area of the triangle as:

150 = 10 h

h = 15 units

Therefore, the length of the shortest altitude of the triangle is 15 units.

Answers

The equilibrium concentration of HI(g) is 0.031 mole. It is less than the initial concentration of HI(g) which is 0.75 mole. Thus, the correct answer is less than.

At 1,000 K, the value of Ke for the reaction is 2.6 x 10-2, in an experiment, 0.75 mole of HI(g), 0.10 mole of of H2(g), H2(g), and 0.50 mole of 12(g) are placed in a 1.0 L container and allowed to reach equilibrium at 1,000 K. We need to determine whether the equilibrium concentration of HI(g) will be greater than, equal to, or less than the initial concentration of HIGG).

In this problem, we need to calculate the concentration of HI(g) at equilibrium. The given reaction is as follows:H2(g) + I2(g) ⇌ 2HI(g)We are given the following information:Initial concentration of HI(g) = 0.75 moleInitial concentration of H2(g) = 0.10 moleInitial concentration of I2(g) = 0.50 moleVolume of container = 1.0 LAt equilibrium, let's consider the concentration of HI(g) as x mole. According to the balanced chemical equation, H2 and I2 are the reactants while HI is the product.

Therefore, the concentration of H2 and I2 will decrease by x mole as they react with each other to form HI at equilibrium. Hence, the concentration of HI(g) will increase by 2x mole since 2 moles of HI are produced from the reaction of 1 mole of H2 and 1 mole of I2. Now, we can write the expression for equilibrium constant (Ke) as follows:Ke = [HI]2 / [H2] [I2]2.6 x 10-2 = (2x)2 / [(0.10 - x) (0.50 - x)]2.6 x 10-2 (0.10 - x) (0.50 - x) = 4x2(0.10 - x) (0.50 - x) = 4x2 - 2.6 x 10-2 (0.10 - x) (0.50 - x)8.54 x 10-3 x2 - 0.365 x + 0.02425 = 0x = 0.031 mole

If

The composition value of two functions g of f of x, i e., g(f(x)) where f(x) = x² +2x -4 and g(x) = 3x +1, is equals to the 3x² + 6x -11.

The composition of two functions g and f, g(f(x)) is the new function we result by performing f first, and then performing g. It can be written as (g º f)(x). The domain of composed function is same as domain of first function or subset of domain of first function. Similarly, range of composed function is same as range second function or subset that. The g(f(x)) can be solved by first we apply f, then apply g to that result. We have f(x) = x² + 2x -4 and g(x) = 3x + 1 and we have to determine g(f(x)). Now, for determining value of (g∘f)(x)= g(f(x)), first we apply f to x to result f(x) and then to apply g to f(x) to get g(f(x)). That is f to x= f(x) = x² + 2x - 4

and g to f(x), we replace x in g(x) by f(x) for g(f(x)).

=> g(f(x)) = 3 f(x) + 1

=> g(f(x)) = 3 ( x² + 2x -4) + 1

= 3x² + 6x - 12 + 1

= 3x² + 6x -11

Find the area of the triangle.
3 in.

; 2.5 in.
6 in.

Answers

Answer:

We can use the formula for the area of a triangle which is given by:

Area = (1/2) x base x height

Where the base and height are the two sides that form the right angle.

Looking at the given triangle, we can see that the sides 3 in. and 5 in. form the right angle, so the base is 3 in. and the height is 5 in.

Therefore, the area of the triangle is:

Area = (1/2) x 3 in. x 5 in.

Area = 7.5 in²

Alternatively, we could also use the sides 2.5 in. and 6 in. to find the area of the triangle. In this case, the base would be 2.5 in. and the height would be 5 in. (since the 6 in. side is not perpendicular to the 2.5 in. side). So the area of the triangle would still be:

Area = (1/2) x 2.5 in. x 5 in.

Area = 6.25 in²

Either way, the area of the triangle is approximately 7.5 in² or 6.25 in², depending on which set of sides we use.

Principal $400 interest rate 7% compounded anually years 3

Answers

The compound interest for the principal value $400, interest rate 7% and compounded anually for 3 years is equals to the $90.2

Compound interest is defined as the interest earn on interest, i.e., here interest on interest . It is denoted by CI and calculated by the below formula, CI

= Amount - principal

and A = P( 1 + r/n)ⁿᵗ

where P --> principal

A --> amount

r --> interest rate

n --> the number of times interest is compounded per year

t --> time in years

Now, we have principal, P = $400

interest rate, r = 7%

time, t = 3 years

here, compounded anually for 3 years so, n= 1

Substitute all known values in above formula,

A = P( 1 + r/n)ⁿᵗ

=> A = 400( 1 + 7/100)³

=> A = 400( 107/100)³

=> A = $490.02.

So, compound interest = A - P

How many sides has a polygon if the sum of its
interior angles is 1440⁰

Answers

Answer:

10 sides

Step-by-step explanation:

We can use the formula for the sum of the interior angles of a polygon to solve this problem. The formula for the sum of the interior angles of a polygon with n sides, where S is the sum of the interior angles, and n is the number of sides of the polygon is:

S = (n - 2) x 180 degrees

If the sum of the interior angles is 1440 degrees, we can set this equal to the formula and solve for n:

1440 = (n - 2) x 180

Dividing both sides by 180, we get:

8 = n - 2

Adding 2 to both sides, we get:

n = 10

Therefore, a polygon with a sum of interior angles of 1440 degrees has 10 sides.

Answers

The following is the correct sequence of steps to prove that if n is a perfect square, then n + 2 is not a perfect square:

Step 1: Assume n = m², for some non-negative integer m.

Step 2: If m = 0, then n + 2 = 2, which is not a perfect square. The smallest perfect square greater than n is (m + 1)².

Step 3: Expand (m + 1)² to obtain (m + 1)² = m² + 2m + 1 = n + 2m + 1 > n + 2 + 1 > n + 2.

Step 4: Let's assume m ≥ 1.

Step 5: Hence, n + 2 is not a perfect square.

The first step in the sequence involves making an assumption to start the proof. The second step entails the derivation of the smallest perfect square greater than n. In the third step, we expand the (m + 1)² expression to get n + 2m + 1. The fourth step is an important one, as it shows that m must be greater than or equal to 1.

In the final step, we conclude that n + 2 is not a perfect square.

llong is 5 ft tall and is standing in the light ofa 1 5 ft lampost her shadow is 4 ft long if she walks 1 ft farther away from the lampost by how much will her shadow lengthen

Answers

long is 5 ft tall and is standing in the light of a 15 ft lamp post her shadow is 4 ft long

To solve the given problem, let's proceed to the solution-

          We know that the Height of the girl = is 5 ft

          The height of the lamp post = is 15 ft

          The length of the shadow = is 4 ft

          Distance between the girl and the lamp post (initially) = 15 - 5 = 10 feet

  the distance between the girl and the lamp post (after walking) is x.

        So, the length of the shadow after walking x distance from the lamp post is given by√(x² + 5²) We need to find the increase in the length of the shadow.

      So, the increase in the length of the shadow is given by(√(x² + 5²) - 4) ft.

     We need to find this increase for x = 11. As x increases, the value of the above expression will also increase.

     So, if we substitute x = 11, then we will get the minimum increase in the length of the shadow.

     Therefore, the increase in the length of the shadow when the girl walks 1 ft away from the lamppost

            = (√(11² + 5²) - 4) ft

the lifetime of a printer costing 200 is exponentially distributed with mean 3 years. the manufacturer agrees to pay a full refund to a buyer if the printer fails during the first year following its purchase, and a one-half refund if it fails during the second year. if the manufacturer sells 100 printers, how much should it expect to pay in refunds?

Answers

The amount of money the manufacturer should expect to pay in refunds is 32.76X dollars.

Let Y denote the life in years of a printer, which is exponentially distributed with mean 3 years. Therefore, the rate parameter λ of the exponential distribution is λ = 1/3, which is obtained from the formula of the exponential distribution, E(Y) = 1/λ = 3 years. The probability that a printer fails during the first year following its purchase is:

P(Y < 1) = F(1) = 1 - e-λt = 1 - e-1/3(1) = 0.2835

The probability that a printer fails during the second year following its purchase is:

P(1 < Y < 2) = F(2) - F(1) = e-1/3(2) - e-1/3(1) = 0.3219 - 0.2835 = 0.0384

The probability that a printer does not fail during the first two years is:

P(Y > 2) = 1 - F(2) = 1 - e-1/3(2) = 0.6797

Let X denote the refund payment in dollars that the manufacturer should pay to the buyer of a printer if the printer fails during the first year, and X/2 denote the refund payment if the printer fails during the second year. Then, the total refund payment per printer is R = XI(Y < 1) + XI(1 < Y < 2)/2 = XI(Y < 1) + (X/2)I(1 < Y < 2), where I(.) is the indicator function that takes the value of 1 if the condition in the parentheses is true and 0 otherwise. The expected value of the total refund payment per printer is:

E(R) = E[XI(Y < 1)] + E[(X/2)I(1 < Y < 2)]

= X(0.2835) + (X/2)(0.0384) = 0.3276X

Hence, the expected total refund payment for 100 printers is:

Expected total refund payment = 100E(R) = 100(0.3276X) = 32.76X dollars. The amount of money the manufacturer should expect to pay in refunds is 32.76X dollars.

What is BODMAS ?

BODMAS stands for "Bracket, Order, Division, Multiplication, Addition, and Subtraction," which is the order of operations used in mathematics to determine the sequence in which calculations are performed.

Question 63 [tex][(6+3)\div(-5-2)](-4)[/tex]

Now put  [tex]a=-5[/tex] and [tex]b=6[/tex]

⇒ [tex][(6+3)\div(-5-2)](-4)[/tex]

⇒ [tex][(9)\div(-7)](-4)[/tex]

⇒ [tex][\frac{9}{-7}] (-4)[/tex]

⇒ [tex]\frac{36}{7}[/tex]

Hence, the answer for question 63 is [tex]\frac{36}{7}[/tex] by using BODMAS rule.

Question 33  [tex](-5)*(3b-2a)-6(a+2b)[/tex]

The length of a rectangle is five times its width. If the permiteter of the rectangle is 72 m, find it’s area

Answers

Let's the width of the given rectangle be x. Then the length will be 5x.

We know that,

[tex] \bf \implies Perimeter_{( Rectangle)} = 2 ( Length + Width) [/tex]

[tex] \sf \implies 2( x+5x) = 72 [/tex]

[tex] \sf \implies 2\times 6x = 72 [/tex]

[tex] \sf \implies 12x =72 [/tex]

[tex] \bf \implies x = 6 [/tex]

Hence, the width of the rectangle is 6 m and the length is 5*6 =30 m

[tex]\bf\implies Area_{( Rectangle) }= Length \times Width [/tex]

[tex] \bf \implies Area _{( Rectangle)} = 30 \times 6 [/tex]

[tex] \bf \implies Area _{( Rectangle) }= 180 m^2 [/tex]

Therefore, the area of the given rectangle is 180 metre square.

Determine the area of the shaded regions in the figures below. Write the final polynomial in standard

Answers

In response to the stated question, we may state that As a result, the area final polynomial in standard form is: -25pi + 50

What is area?

The size of a surface area can be represented as an area. The surface area is the area of an open surface or the border of a three-dimensional object, whereas the area of a planar region or planar region refers to the area of a shape or flat layer. The area of an item is the entire amount of space occupied by a planar (2-D) surface or form. Make a square with a pencil on a sheet of paper. A two-dimensional character. On paper, the area of a form is the amount of space it takes up. Assume the square is made up of smaller unit squares.

To calculate the area of the darkened areas, subtract the area of the circle from the area of the square.

Then, determine the square's side length. Because the circle's diameter is ten, the radius is five. Because the diagonal of a square equals the diameter of a circle, we can use the Pythagorean theorem to calculate the side length:

[tex]s^2 + s^2 = 10^2\\2s^2 = 100\\s^2 = 50\\s = \sqrt(50) = 5 * \sqrt(2)[/tex]

The square's area is then:

[tex]A_{square} = s^2 = (5 * \sqrt(2))^2 = 50[/tex]

The circle's area is:

[tex]A_{circle} = pi * r^2 = pi * 5^2 = 25 * pi[/tex]

The shaded region's area is:

[tex]A_{shaded} = A_{square} - A_{circle} = 50 - 25 * pi[/tex]

As a result, the final polynomial in standard form is:

-25pi + 50

Groups A, B, and C have means of 4, 6, and 8, respectively. There are 15 cases in total, with equal sample sizes in each group. Within is 120. 16-7. 16-4a, the value of omega-squared is 0.25.

What is omega-squared?

       In statistics, omega-squared is a measure of effect size that can be used for one-way ANOVA to determine how much variance is due to the treatment or independent variable. It is calculated by dividing the between-group variance by the total variance, which includes both the within-group and between-group variance.

       Omega-squared is used to determine the percentage of variance accounted for by a particular factor or treatment. It is represented as ω2 and ranges from 0 to 1, with higher values indicating a stronger relationship between the independent variable and the dependent variable.

       The formula for omega-squared is as follows:

                         ω2=SSBetween / SSTotalSSWithin

                              = SSTotal - SS Between

         Where SSTotal is the sum of squares for the total variance.SSBetween is the sum of squares between the groups, and within is the sum of squares within the groups.

     The given information is:

                       Mean of group A = 4Mean of group

                                                 B = 6Mean of group

                                                 C = 8Total cases

                                                    = 15SSWithin

                                                    = 120

             We can calculate the sum of squares between the groups as follows:

                        SSTotal = SSBetween + SSWithinSSTotal

                                      = (nA + nB + nC - 1) × (σA² + σB² + σC²)SSBetween

                                      = SSTotal - SS Within SS Between

                                      = (3 - 1) × (42 + 62 + 82) - 120SSBetween

                                      = 80 Next,

           we can calculate the total variance as:

                      SSTotal = SSWithin + SSBetweenSSTotal

                                    = 120 + 80SSTotal

                                     = 200

            Now, we can calculate omega-squared as follows:

                     ω2 = SSBetween / SSTotalω2

                           = 80/200ω2

                           =0.4

       Hence, the value of omega-squared is 0.25.
