Rectangles F and H are similar. If rectangle F has dimensions of 5x10 and rectangle H has dimensions of 15 by an unknown amount.

Answer:

The answer is 30 or 7.5

Step-by-step explanation:

There are two answers because you haven't specified whether the 15 corresponds with the 5 or the 10 so I did both.

If the 15 corresponds with the 5 then the scale factor is 3 because 15 ÷ 5 = 3. To find the unknown amount you have to multiply the 10 by 3 to get 30.

If the 15 corresponds with the 10 then the scale factor is 1.5 because 15 ÷ 10 = 1.5. To find the unknown amount you have to multiply the 5 by 1.5 to get 7.5.

So depending on whether the 15 corresponds to the dimension 5 or 10 you have two answer, you can use the one that applies to you.

Please help!! Which values of a and b in the exponential function y=a*b^x would result in the following graph?

Masja [62]

Answer: $a=-3, b=2$

Step-by-step explanation:

1. To solve this problem substitute the values of $a$ and $b$ into the function $y=a*b^{x}$ and prove for the value $x=0$ .

2. When $x=0$ , $b^{0}=1$ and $a*1=a$ ; this means that the graph of the function should cut in the axis $y=a$ , if this does not happen, the values of $a$ and $b$ are not the right ones.
