I think it depends on the depends on what result you are looking for if it is the exponential model used in the problem. In this problem, it does show how someone gets this results. Both the exponential growth and decay can be used in exponential functions.
Answer:
d. 2.4 in
Step-by-step explanation:
So initially w/o frame the area was 5 x 7 = 35 sq in.
Now we have to add the width of the frame to both dimensions.
(5+w)(7+w) = 69.56 sq in
35 + 7w + 5w + w² = 69.56
w² + 12w + 35 = 69.56
w² + 12w - 34.56 = 0
I use the quadratic formula to solve this (x = -b±√b²-4ac / 2a). I cheat by using a quadratic program on the calculator :,)
w = 2.4
w = -14.4
Since we can't have a negative width, the answer must be <u>w = 2.4 inches.</u>
You can also just plug the answer choices one-by-one into the calculator with guess-and-check because this is multiple choice.
7*11=77 because 7 and 11 are 4 apart Enjoy!=)
Answer
Because the function says 1.045 means 1+0.045
0.045=4.5%
So your answer is
4.50%
