576 inches = 4 square feet

Answer:

the image of the dilation a reduction or an enlargement of the original figure

Step-by-step explanation:

The scale factor will be within the figure

Answer:

Reduction, 1/2

Step-by-step explanation:

We can already see that the prime figure is smaller, so we can justify that it is a reduction.

We can look at the points of the original figure and if we divide them by 2, we get the prime figure coordinates so we can conclude that the scale factor is 1/2.

Answer:

Option A. $1713.98

Step-by-step explanation:

You have to calculate your parents' monthly fixed expenses by the given expenses list.

Rent = $998.50

Groceries ( bi-weekly ) = $195.40 Monthly groceries = (195.40×2)

Charge card = $258.90

Cell phone = $65.78

Name brand Khakis for work (store brand optional ) = $34.95

Total expenses are 998.50 + (195.40×2) + 258.90 + 65.78

Answer:

Refer to step-by-step.

Step-by-step explanation:

12.  x = 28

BC = x

AB = 96

AC = 100

We use the Pythagorean theorem to find the value of x.

a² + b² = c²

x² + 96² = 100²

x² + 9216 = 10000

x² = 10000-9216

x² = 784

√x² = √784

x = 28

13. x = 64

a² + b² = c²

48² + x² = 80²

2304 + x² = 6400

x² = 6400 - 2304

x² = 4096

√x² = √4096

x = 64

14. YES and 25 = 25

a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

So this means that AB is tangent to the circle.

15. NO and 45 ≠ 49

a² + b² = c²

3² + 6² = 7²

9 + 36 = 49

45 = 49

So this means the AB is not tangent to the circle.

16. x = 4.5 and P = 52

To find the value of x, we need to determine the value of our hypotenuse.

QU is congruent to QT, therefore, QT = 4

UR is congruent with SR, therefore, UR = 13

PS is congruent to AB, therefore:

2x = 9

Divide both sides by 2

x = 4.5

The perimeter of a triangle is:

P = a + b + c

a = 9 + 4 or 13

b = 2(4.5) + 13 or 22

c = 4 + 13 or 17

P = 13 + 22 + 17

P = 52

17. x = 13 and P = 72

TJ is congruent to UJ, therefore, TJ = 13

x = 13

The perimeter of a parallelogram is:

P = 2(a+b)

a = HR + RK

b = KU + UJ

a = 13 + 5 or 18

b = 5 + 13 or 18

P = 2(18 + 18)

P = 2(36)

P = 72

18. x = 8 and P = 80

We know that part of the whole of 26 is 18 because one side is congruent to 18.

to find the value of the other half, we simply subtract 18 from 26.

26 - 18 = 8

x is congruent to 8, therefore x = 8

The line segment 14 is congruent to the opposite segment of x, therefore making the value 14.

So then we have:

a = 8 + 14 or 22

b = 26

c = 18 + 14 or 32

P = a + b + c

P = 22 + 26 + 32

P = 80

19. x = 6 and P = 52

Now we have the case of x + 2 is congruent to 8.

x + 2 = 8

Combine like terms.

x = 8 - 2

x = 6

Now that we have the value of x, we can simply look for the value of the line segment attached to it.

4 is congruent to the line segment attached to x + 2, therefore the value is 4.

To find the perimeter we have to add all sides together.

P = (8+5)+(5+9)+(9+4)+(8+4)

P = 52

20. x = 5, y = 2, z =10, and P = 68

Let's take this one step at a time.

First we look for x.

2x + 2 = 3x - 3

Combine like terms.

2x - 3x = -3 - 2

-x = -5

Divide both sides by -1.

x = 5

Now let's get the value of y.

5y - 2 = 3y + 2

Combine like terms.

5y - 3y = 2 + 2

2y = 4

Divide both sides by 2.

y = 2

Now let's look for z.

34 - 2z = z + 4

Combine like terms.

-2z - z = 4 - 34

-3z = -30

Divide both sides by -3.

z = 10

Now that we have the values of x, y, and z. We can substitute them to find the values of our segments.

2x + 2

2(5) + 2 = 12

3x - 3

3(5)-3 = 12

5y - 2

5(2) - 2 = 8

3y + 2

3(2) + 2 = 8

z + 4

10 + 4 = 14

34 - 2z

34 - 2(10)

34 - 20 = 14

Now that we have our values let's look for our perimeter.

P = a + b + c

P = (12 + 8) + (12 + 14) + (14 + 8)

P = 20 + 26 + 22

P = 68

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 3, 7 ] and from the graph

f(b) = f(7) = 2

f(a) = f(3) = 10, hence

average rate of change = [tex]\frac{2-10}{7-3}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2

Answer:

x = -10

Step-by-step explanation:

You're looking for a number that gives -1000 when cubed. In other words, you're looking for the cubic root of -1000.

In fact, cubic root and cube are one the opposite of the other, meaning that

[tex] a^3=b \iff \sqrt[3]{b}=a[/tex]

So, you have

[tex]x^3=-1000 \iff x = \sqrt[3]{-1000} = -10[/tex]

There is no solution for the given equation |x+5|=−3.

Two or more expressions with an Equal sign is called as Equation.

The equation |x+5| = -3 has no solutions in the real number system because the absolute value of any real number is always non-negative, and can never be negative.

Therefore, there are no values of x that make the left-hand side of the equation equal to -3, and the equation has no solutions.

Graphically, this means that there is no point on the number line where the distance from that point to -5 is equal to -3.

The solution set for the equation |x+5| = -3 is the empty set .

Hence, for the given equation |x+5|=−3 has no solution.

Answer:

h = 20 cm

Step-by-step explanation:

The volume (V) of a square based prism is

V = area of base × h ( h is the height )

area of square base = 9 × 9 = 81 cm²

Hence

81h = 1620 ← equation to be solved

Divide both sides by 81

h = 20 cm

Answer:

l = 7 in; w = 3 in

Step-by-step explanation:

The formula for the area of a rectangle is

A = lw

Data:

A = 21 in²

l = w + 4

Calculation:

                 21 = (w + 4) × w

                 21 = w² + 4w

w² + 4w - 21 = 0

(w + 7)(w - 3) = 0

w + 7 = 0     w - 3 = 0

      w = -7         w = 3

We reject the negative value, so w = 3 in.

21 = l × 3

l = 7

The rectangle is 7 in long and 3 in wide.

Step-by-step explanation:

h = -16t² + 600

When the sack reaches the ground, h = 0.

   0 = -16t² + 600

Answer:

The measure of angle ALO = 35°

Step-by-step explanation:

* Lets talk about the tangents to a circle drawn from a point

 outside the circle:

- They are equal in length

- They are perpendicular to the radii at the point of tang-ency

- If we join the points of tang-ency withe the center of the circle

 and join the outside point with center of the circle, we

 formed two congruent triangles

* Now lets check our problem

- AL and LB are two tangents to the circle O ant points A and B

∴ LA = LB ⇒ (1)

- OA and OB are radii in circle O

∴ OA = OB ⇒ (2)

∴ OA ⊥ AL and OB ⊥ BL ⇒ radius and tangent

∴ m∠OAL = 90° , m∠OBL = 90

∴ m∠OAL = m∠OBL ⇒ (3)

* From (1) , (2) , (3)

- The two triangles LAO and LBO are congruent ⇒ SAS

- SAS is one case of congruence

∵ The lengths of two sides and the measure of the including

  angle between them in one triangle equal to the

  corresponding sides and angles in the second triangle,

  then the two triangles are congruent

∴ m∠LOA = m∠LOB

∵ m∠AOB = 110°

∴ m∠LOA = m∠LOB = 110/2 = 55°

* In ΔLAO

∵ m∠ LAO = 90° , m∠LOA = 55°

∴ m∠ALO = 180 - (90 + 55) = 180 - 145 = 35°

* The measure of angle ALO = 35°

You can solve this by setting up a proportion. 4/6 = x/9. Cross multiply to get 6x=36. Divide both sides by 6 to get x=6.

The length of the missing segment is 12 inches.

We know that the two triangles are similar, so the ratio of their corresponding side lengths is equal.

Let x be the length of the missing segment.

We then  have the following equation:

x/13 = 12/26

= 12/26 * 13

x = 12 inches

Therefore, the length of the missing segment is 12 inches.
