Scale factor is defined as
s=size of image / size of preimage.
Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.
So scale factor = B'O'/BO = 9/27 = 1/3.
For this case we have the following equation:
To find the time when it reaches its maximum height, we must derive the equation.
We have then:
Then, equaling to zero and clearing the time we have:
Answer:
the ball reaches its maximum height at:
C. 2
20000x.05= 1000 added minnows per year, with the algae decline, we loose 750 minnows per year. 250 minnows are added every year. The rate 5% every year would be exponential growth, and the decline of 750 minnows per year is a result of a negative constant (not exponential decline.)
Answer:
(2,5)
Step-by-step explanation:
The answer is 42 mpg, all you need to do is divide 126/3 or 210/5 and they both equal 42.
