Answer:

1. HK = 24

2. x = 13

3. x = -26

4. ∠ABC = 120°

Step-by-step explanation:

(1) In all parallelograms, the diagonals bisect each other, or split each other into two congruent (same) halves.

We are given parallelogram HJKL. Its diagonals are HK and JL, because they both are segments that connect two opposite vertexes.

This means that HK and JL are bisected.

Thus, HM is half of HK.

Let's make an equation to represent this situation and solve for HK.

[tex]HM = \frac{1}{2}HK[/tex]

⇒ [tex]12 = \frac{1}{2}HK[/tex] . . . . . . substitute known values

⇒ [tex]12(2) = \frac{1}{2}HK(2)[/tex] . . . . . . multiply the LHS and RHS by 2 to isolate HK

⇒ ∴ [tex]24 = HK[/tex] . . . . . . compute

(2) This problem is similar to #1, so we can use the same concepts as #1.

However, we are given an expression instead of integers.

The only thing that's different about this problem is that we need to solve for x, not a diagonal or part of a diagonal.

VX and UW are the diagonals of parallelogram UVWX.

Thus, VX and UW are bisected.

Thus, the VY and YX are the same length, because they are split in half.

Let's make an equation to represent this situation and solve for x.

[tex]VY = YX[/tex]

⇒ [tex]80 = 6x + 2[/tex] . . . . . . substitute the known values

⇒ [tex]78 = 6x[/tex] . . . . . . . . . subtract 2 from the LHS and RHS

⇒ ∴[tex]13 = x[/tex] . . . . . . . . . divide both sides by 6 to isolate x

(3) This problem uses the exact same concepts and steps as #2.

Thus, RS and SP are the same length.

Let's make an equation to represent this situation and solve for x.

[tex]RS = SP[/tex]

⇒ [tex]65 = -2x - 7[/tex] . . . . . . . . substitute the known values

⇒ [tex]72 = -2x[/tex] . . . . . . . . . . . add 7 to the LHS and RHS

⇒ ∴[tex]-36 = x[/tex] . . . . . . . . . . . divide both sides by -2 to isolate x

(4) In a parallelogram, the opposite angles are congruent (the same).

In parallelogram ABCD, we are given ∠CDA and asked to solve for ∠ABC.

∠ABC and ∠CDA are opposite angles.

∠CDA = 120°

∠ABC = ∠CDA

∴ ∠ABC = 120°

The parallelogram HJKL is handed to us. The segments HK and JL, which both link two vertexes that are in opposition to one another, serve as its diagonals, triangle HK = 24;  x = 13;  x = -26; ∠ABC = 120°

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

All parallelograms have diagonals that cut them in half or divide them into two congruent (same) halves.

HK = 24, x = 13, x = -26, and ABC = 120 degrees.

The parallelogram HJKL is handed to us. The segments HK and JL, which both link two vertexes that are in opposition to one another, serve as its diagonals.

As a result, HK and JL are divided. HM therefore makes up half of HK.

The linear equation L, which is a translation of line M, can be written as:

y = (2/3)*x - 2

So the correct option is the last one.

First, we need to find the equation of line M.

Remember that the general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = -2, then we wll get:

y = a*x - 2

And we can also see that the line passes through (-3, -4)

Replacing these values we will get:

-4 = a*-3 - 2

-4 + 2 = -3a

-2/-3 = a

2/3 = a

So line M is:

y = (2/3)*x - 2

And line M is a translation of 3 units down and 2 units left of L, then L is a translation of 3 units up and 2 units to the right, then we can write line L as:

y = (2/3)*(x - 2) - 2 + 3

y = (2/3)*x + (2/3)*-2 - 2 + 3

y = (2/3)*x - 4/3 + 1

y = (2/3)*x - 1/3

So the correct option is the last one.

Answer:

The cost of renting a car can be represented by the expression:

C = 30m + 0.25m

Where C is the total cost, 30 is the fixed cost per day, and 0.25 is the cost per mile.

Step-by-step explanation:

Value of C = 25 when d = 625

Square root is denoted by operator√. It is a factor which can be multiplied. When a square root of a particular number is multiplied by itself, we get the original number. As example, square root of 12 is √12 is multiplied by √12 and we get (√12) ² = 12.

What is the value of C when d = 625?

As per question, C varies directly as the square root of d.

C = 16 when d = 256

C = √d

√d = √256

√d = 16

when d = 625

the value of C will be,

C = √d

C =√625

C = 25

When, d = 625, the value of C =25

===========================================

Work Shown:

A = final value = 38750

P = amount loaned = 25000

i = interest

i = A - P = 38750 - 25000 = 13750

Now apply the simple interest formula to solve for t.

i = P*r*t

13750 = 25000*0.055*t

13750 = 1375*t

t = 13750/1375

t = 10 years to pay off the loan

On solving the provided question, we can say that coordinates are (-2,2) and (0,-2), inequality equation will be => y[tex]\leq[/tex] -2x + 2

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

To represent a whole, any number of equal parts or fractions can be utilized. In standard English, fractions show how many units there are of a particular size. 8, 3/4. Fractions are part of a whole. In mathematics, numbers are stated as a ratio of the numerator to the denominator. These can all be expressed as simple fractions as integers. A fraction appears in a complex fraction's numerator or denominator. The numerators of true fractions are smaller than the denominators. A sum that is a fraction of a total is called a fraction.

The limit of the function lim t→0+ cos(t), cos(t), [tex]t^3[/tex] ln(t) as t approaches 0 from the right is not defined.

The limit of cos(t) and [tex]t^3[/tex] ln(t) is zero as t approaches zero from the right. However, the limit of cos(t) as t approaches zero from the right is not defined. This is because the cosine function oscillates between -1 and 1 as t approaches zero, and therefore it does not approach a specific value. The limit of the entire function is undefined, as one of the components of the function is undefined.

It's important to note that if you have differentiability conditions, you can use L'Hopital's rule to find the limit, but in this case, L'Hopital's rule can't be applied since the function is not differentiable at t = 0.

Answer:

1. Growth

2. Decay

3. Decay

Step-by-step explanation:

Growth means as x increases, y increases too. On the other hand, decay means as x increases, y decreases. There's the theory for exponential function regarding this growth and decay.

Growth

If the base is not a decimal or a fraction then it's growth.

Decay

If the base is a decimal or a fraction then it's decay.

From the problem, first function has base of 5. Hence, it's growth. On the other hand, second and third function both have decimal and fraction as the base. Hence, it's decay.

When considering growth or decay graph, we can ignore the coefficient since it doesn't determine the growth and decay. The only thing that determines if a function increases or decreases is the base under the exponent.

To find the mean (average) of a set of numbers, we add them together and divide by the number of items in the set.

The first step is to convert all the fractions into a common denominator. In this case, the least common multiple of 3, 3, and 4 is 12.

2 1/3 = 7/3

3 2/3 = 11/3

5 1/4 = 21/4

Now we can add these numbers together:

7/3 + 11/3 + 21/4 = (7 + 11 + 21) / 3 = 39/3 = 13

There are three numbers, so we divide by 3.

Mean = 13/3 = 4 1/3

So the mean of 2 1/3, 3 2/3 and 5 1/4 is 4 1/3.
