Answer:

The dimensions of the original picture is 3 inches by 5 inches .

Step-by-step explanation:

Let the length of original picture be x

Let the breadth of original picture be y

A scale drawing is made to enlarge a picture by using a scale factor of 3.

So, Length of enlarged picture = 3x

So, breadth of enlarged picture = 3y

Now we are given that . The enlarged picture is 9 inches by 15 inches.

So, 3x = 9                and       3y=15

      x = \frac{9}{3}                and       y=\frac{15}{3}

       x = 3                 and       y=5

Hence the dimensions of the original picture is 3 inches by 5 inches .

Find the derivative of g(y)=(y-4)*(2y+y^2)
sasho [114]

Answer:

g'(y)=3y^2-4y-8

Step-by-step explanation:

start by foiling out the given function

g(y)=(y-4)(2y+y^2)\\=2y^2+y^3-8y-4y^2\\=y^3-2y^2-8y

next, use the power rule to find the derivative

power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.

g'(y)=3y^2-4y-8
