Answer:

The correct option is 1 and 4 are correct.

Step-by-step explanation:

The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.

The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.

In dilation the corresponding angles remains same and the corresponding sides are equal.

\angle P=\angle P'

\angle PQR=\angle Q'

\angle R=\angle P'QQ'

PR=P'Q

PQ=P'Q'

RQ=QQ'

Therefore option 1 and 4 are correct.

How to find the measure of yz
stira [4]
Use the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)

YZ/sin30=50/sin90

YZ=50sin30   (sin90=1 :P)

YZ=25m

Use the 30,60,90° triangle ratios 1, √3, 2

YZ/1=50/2

YZ=25m

Using the Pythagorean Theorem....

(2*25)^2=YZ^2+(√3*YZ)^2

2500=YZ^2+3YZ^2

2500=4YZ^2

625=YZ^2

25m=YZ

PLS HELP I WILL GIVE BRAINLIEST 1- If you are driving at a constant speed of 55 miles per hour, give an estimate of how many mil
Hatshy [7]

Answer:

1- 72 miles

2-$3

3- 50(0.50 x c)

Step-by-step explanation:

For Number 1 we have to do 55 divided by 60 which is about 0.90 and then we multiply that by 1 hour and 20 minutes which in minutes is 80. 0.90 x 80 = 72 exactly.

For Number 2 we have to divide 36.25 by 11.5 rounded is 36/12 whish is 3.

For number 3 c stands for number of channels

17. Scott cuts his birthday cake into nine equal pieces and eats two of them.
Roman55 [17]

Answer:

A. 0.2222

B. Repeat indefinitely

Step-by-step explanation:

A. We have that Scott has 9 pieces in total and he eats 2 of them. That means he eats 2 <em>out of </em>the 9, so we have 2 ÷ 9. (see attachment)

The decimal form is: 0.2222.

B. Clearly, we can see that throughout the long division, we keep getting 20 - 18 = 2, which makes another 20 and so on. So, this will repeat indefinitely.

The function V(t)=1,000(1.06)^t models the value of an investment after t years. What does the ".06" represent in the function?
slamgirl [31]

Answer:

A

Step-by-step explanation:

Looking at the function, we have;

V(t) = 1,000(1.06)^t

Mathematically, the amount earned on an investment that offers a particular constant percentage return to a particular number of years can be written as;

V = I(1 + r)^t

where V is the value of the investment after some certain number of years

I is the initial amount invested

r is the constant percentage increase

and t is the number of years.

Let’s now re-write what we can deduce in the question.

This is;

V(t) = 1000(1 + 0.06)^t

Thus what this 0.06 represents is r which is the constant interest rate
