Answer:

B, C, E are true

Step-by-step explanation:

A = l*w

The original rectangle is 6 by 4 with A = 24

The 1st enlargement = 6*3 by 4*3

18 by 12 with A = 216

The second enlargement is 18*3 by 12*3

54 by36 with A =1944

A.The area of the first enlargement is 72 square inches.

False it is 216

B.The area of the second enlargement is 1,944 square inches.

True

C.The area of the second enlargement is (3 squared) squared times the original area.

216/24 =9 True

D.The area of the second enlargement is 3 times the area of the first enlargement.

1944/24 = 9 False

E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.

The scale factor is 3 3^2 =9 216/24 =9

True

What is the slope of the line that contains the points (-1, 2) and (3, 3)?

iren [92.7K]

Answer:

1/4

Step-by-step explanation:

Slope of a line can be found if given two points by using the formula $\frac{y_2-y_1}{x_2-x_1}$ where $(x_1,y_1) \text{ and } (x_2,y_2)$ are points on the line.

However, I like to line up the points vertically and subtract then put 2nd difference over 1st difference.

Like this:

( 3 , 3 )

-( -1 , 2 )

---------------------

4 1

So the slope is 1/4.

2) As part of traffic accident investigations, the speed of a car involved can be approximately determined by checking actual sk

dezoksy [38]

a) The speed of car was 60 mph.

b) The speed of car was 45 mph.

Step-by-step explanation:

Given,

a = actual skid marks

p = test skid marks

Formula;

$s=30*\sqrt{\frac{a}{p}}\\$

a) a = 144 feet, p = 36 feet

Putting in formula;

$s = 30*\sqrt{\frac{144}{36}}\\\\s=30*\sqrt{4}\\\\s=30*2\\\\s=60$

The speed of car was 60 mph.

b) a = 153 feet, p = 68 feet

Putting in formula;

$s=30*\sqrt{\frac{153}{68}}\\\\s=30*\sqrt{2.25}\\\\s=30*1.5\\\\s=45$

The speed of car was 45 mph.

WILL BE MARKED BRAINLIEST!!!! <br> x-y=4 <br> How do you get the y alone?

yanalaym [24]

The answer is y = x-4.

<u>Step-by-step explanation</u>:

The given expression is x-y=4
Keep y alone on one side and move remaining terms to the other side.

⇒ -y = 4-x

To have y alone, Multiply the above expression with -ve sign on both sides.

⇒ y = x-4
