Answer: 3:2 and 2:3
Step-by-step explanation:
Scale factor is image/preimage.
So from A to B, the image is B and the preimage is A, so the scale factor is 6/4 = 3/2.
Similarly, from B to A, the scale factor is 4/6=2/3
Answer:
$2.50n + $24 (6x4) = e
Step-by-step explanation:
$6x4 = $24
$2.50n + $24 (6x4) = e
I hope this helps you on your test :)
There are 5 blue shirts and only one is big, so the probability would be 1/12. The percentage would be approximately 8%
Answer:
<em>The x-coordinate is changing at 10 cm/s</em>
Step-by-step explanation:
<u>Rate of Change</u>
Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

We have

Or, equivalently

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

Solving for dx/dt

Plugging in the values x=1, y=3, dy/dt=5

The x-coordinate is changing at 10 cm/s
You didn't include a picture of the answer choices, but this is what the answer would look like. Pretend the different shapes represent different rows:
ΔΔΔΔ
ββββ
αααα
There are three rows. 4 Books in each row.
