Answer:

A function is defined as an operation on a number, which gives only one output for every input

while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function

Now, lets look at the graph

for the input value '4' , we notice that there are 2 possible outputs. The output can be either 2.5 or -2.5

Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

Answer:

Yes. The are equivalent to each other

Step-by-step explanation:

21 : 35

The LCM of these two numbers is 7

When we divide both of them by 7, we're left with 3:5

24 : 40

The LCM of these two numbers is 8

When we divide both numbers by 8, we're left with 3:5

And, 3:5 = 3:5, so we can say 21:35 = 24:40

PS: Also, if we multiply 21 : 35 by 8 and 24 : 40 by 7, we get the same result, i.e 168 : 280 which also proves that they are equivalent.

Answer:

68

Step-by-step explanation:

bidmas rule

8×8=64

64+68

Applying the product rule gives

[tex]\displaystyle \frac{d}{dx}\int_1^{x^2}\frac{2t}{1+t^2}\,dt \times \int_1^{\ln(x)}\frac{dt}{(1+t)^2} + \int_1^{x^2}\frac{2t}{1+t^2}\,dt \times \frac{d}{dx}\int_1^{\ln(x)}\frac{dt}{(1+t)^2}[/tex]

Use the fundamental theorem of calculus to compute the remaining derivatives.

[tex]\displaystyle \frac{4x^3}{1+x^4} \int_1^{\ln(x)}\frac{dt}{(1+t)^2} + \frac{1}{x(1+\ln(x))^2}\int_1^{x^2}\frac{2t}{1+t^2}\,dt[/tex]

The remaining integrals are

[tex]\displaystyle \int_1^{\ln(x)}\frac{dt}{(1+t)^2} = -\frac1{1+t}\bigg|_1^{\ln(x)} = \frac12-\frac1{1+\ln(x)}[/tex]

[tex]\displaystyle \int_1^{x^2}\frac{2t}{1+t^2}\,dt=\int_1^{x^2}\frac{d(1+t^2)}{1+t^2}=\ln|1+t^2|\bigg|_1^{x^2}=\ln(1+x^4)-\ln(2) = \ln\left(\frac{1+x^4}2\right)[/tex]

and so the overall derivative is

[tex]\displaystyle \frac{4x^3}{1+x^4} \left(\frac12-\frac1{1+\ln(x)}\right) + \frac{1}{x(1+\ln(x))^2} \ln\left(\frac{1+x^4}2\right)[/tex]

which could be simplified further.

The equation of pressure is given by:

[tex]p = \frac{f}{s} [/tex]

where p is the pressure.

f is the applied force.

s is the surface area to which the force is applied.

I will start off by calculating the surface area of the table top given by:

[tex]s = l \times w = 1.8 \times 1.2 = 2.16[/tex]

s=2.16 m²

We know that f=400 N, that is given.

[tex]p = \frac{400 \: n}{2.16 \: m {}^{2} } [/tex]

Plug this on your calculator (excluding the units lol)

[tex]p = 185.185 \frac{n}{m {}^{2} } [/tex]

[tex]p = 185 \frac{n}{m {}^{2} } [/tex]

Answer:   x = 3/4; y = 19/6

Step-by-step explanation:

plug in y = 2/3x + 8/3​ into 4x - 2y = -4

4x - 2(2/3x + 8/3​) = -4

  4x  - 4/3x - 18/3 = -4

        12/3x - 4/3x = -12/3 + 18/3

                    8/3x = 6/3

                    8/3x = 2

                         x = 2(3/8)

                         x = 6/8  = 3/4

plug the x value into y = 2/3x + 8/3

y = 2/3(3/4) + 8/3

y = 1/2 + 8/3

y = 3/6 + 16/6

y = 19/6

Answer:

  75°, 112°, 125°, 113°, 89°, 98°, 90°, 130°

Step-by-step explanation:

The marked angle pairs are one of ...

1) vertical angles (congruent): ? = 75°

2) linear pair (supplementary): ? = 180° -68° = 112°

3) consecutive interior (supplementary): ? = 180° -55° = 125°

4) alternate interior (congruent): ? = 113°

5) corresponding (congruent): ? = 89°

6) alternate exterior (congruent): ? = 98°

7) alternate interior (congruent): ? = 90°

8) alternate interior (congruent): ? = 130°

Additional comment

For parallel lines in general, all of the obtuse angles are congruent, and all of the acute angles are congruent. All of the obtuse angles are supplementary to the acute angles. (In (7), all angles are right angles, so all are congruent.) These facts can help you with problems like this one.

Learning the language (names/relationships) of these angles will be helpful to you in the future.

Answer : Life Insurance

Explanation : Have A Good Day

◊ YusuCr ◊

The optional deduction for money to be taken out of an employee's paycheck is life insurance.

Option C is the correct answer.

An employee's paycheck is a document issued by an employer that lists the amount of money an employee has earned during a certain pay period and the amount of money that has been withheld for taxes, insurance, and other deductions.

It also includes the net amount of money that the employee is entitled to receive after all deductions have been made.

We have,

Life insurance is an optional deduction for money to be taken out of an employee's paycheck.

The other options listed (Federal income tax, Medicare, and Social Security) are typically mandatory deductions required by law.

Thus,

The optional deduction for money to be taken out of an employee's paycheck is life insurance.

Answer:

77.5

Step-by-step explanation:

For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.

(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)

Put the 125 to the side, and multiply 50 to 0.30, you get 15.

Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.

Add 62.5 and 15 together, that gives you 77.5

Answer:

Two possible equations:

Point-slope form is [tex]y-1=-\frac{2}{3} (x+3)[/tex]

Slope-Intercept form is [tex]y=-\frac{2}{3}x+-1[/tex]

Step-by-step explanation:

So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope([tex]m[/tex]).

Then, we  need to know the slope-intercept form of an equation. The point slope form is [tex]y-y1=m(x-x1)[/tex] where [tex]m[/tex] is the slope of the line and [tex]y1[/tex] and [tex]x1[/tex] represent the point on the graph. This is the equation we'll use for the line.

So now that we understand what we need to find, we need to find the slope of the existing line. To do this we use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex]. We can plug in the points (-2,3) and (1,1) on the graph to get [tex]m=\frac{1-3}{1+2}[/tex]. When we simplify this we get [tex]m=-\frac{2}{3}[/tex] so we know our slope is [tex]-\frac{2}{3}[/tex]. Lastly, all we need to do is plug the slope and the new point into our point slope equation to get [tex]y-1=-\frac{2}{3} (x+3)[/tex].

If you needed to go further and put this into slope-intercept form, you could solve the equation for y to get [tex]y=-\frac{2}{3}x+-1[/tex]

The maximum length of the rectangular front is the highest length of the rectangular front, and the value is 128.1 feet

Let the dimension of the rectangular front be x and y.

Such that:

y = 2x

So, the area of the rectangular front is:

A = xy

[tex]A = 2x^2[/tex]

The surface area of the pyramid roof is:

A = 4bh

Where:

b = base =25

h = height =18

So, we have:

[tex]A = 4* 25 * 18[/tex]

[tex]A = 1800[/tex]

The total surface area of the figure is:

[tex]T = 1800 +2x^2[/tex]

The range of the cost of material is: $25 per square foot to $50 per square foot.

So, the maximum cost is:

[tex]50 * (1800 +2x^2) = 500000[/tex]

Divide both sides by 50

[tex]1800 +2x^2 = 10000[/tex]

Subtract 1800 from both sides

[tex]2x^2 = 8200[/tex]

Divide both sides by 2

[tex]x^2 = 4100[/tex]

Take the square root of both sides

x = 64.03

Recall that:

y = 2x

So, we have:

y = 2 * 64.03

y = 128.06

Approximate

y = 128.1

Hence, the maximum possible length of the rectangular front of the building is 128.1 feet

Hello.

Let's use the slope formula in order to find the slope:

[tex]\bf{\displaystyle\frac{y_2-y_1}{x_2-_x_1}[/tex]

Where

y₂ = the y-coordinate of the second point (-6)

y₁=the y-coordinate of the first point (6)

x₂=the x-coordinate of the second point (11)

x₁=the x-coordinate of the first point (7)

Plug in the values:

[tex]\bf{\displaystyle\frac{-6-6}{11-7} =\frac{-12}{4} =-3[/tex]

Therefore, m (the slope) is equal to -3.

I hope it helps.

TRY USING SYMBOLAB I USE ALL THE TIME

Lets have the younger person be x.
The older person will be 8x + 3.

The sum of their ages is 21, so we can get this equation:

x + (8x+3) = 21

9x+3 = 21
Subtract 3 from both sides
9x = 21

x=3 --> The younger person is 3 years old, and now we can substitute that for the older person (8x+3):

(3 * 8) + 3 = 27

The younger person is 3 years old, and the older person is 27.

Step-by-step explanation:

A right angled triangle is given to us and we would like to find out the value of sin(A) .

From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

[tex]\longrightarrow A = 30^o[/tex]

On using sin both sides ,

[tex]\longrightarrow sin(A) = sin30^o[/tex]

As we know that the value of sin30° = 1/2. So;

[tex]\longrightarrow sin(A)=\dfrac{1}{2} [/tex]

Simplify by converting it into decimal ,

[tex]\longrightarrow \underline{\underline{sin(A) = 0.5}} [/tex]

Hence option B is correct .
