Describe the % change of the function y = 45(1.39)^x

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

45 was divided by a power of ten to get 4.5. what power of ten was it divided by? people 4.5

What would the rule be for the reflection of y=-3
