Answer:

4

Step-by-step explanation:

The function is given as 5c+cd, c=1/5 and d=15d.

We evaluate by substituting the given values of c and d in the function:

5c+cd, c=1/5 \ \ \, d=15\\\\=5\times \frac{1}{5}+\frac{1}{5}\times 15

=1++3\\\\=4

After substituting, we find the function's equivalent as 4.

Hence, the value of the function is 4

One hundred twenty feet of fencing encloses a rectangular garden on three sides. One side of the garden is the side of a barn an
andre [41]

Answer: The garden has dimensions 30 ft wide X 60 ft long

Step-by-step explanation:

Denote by W the width of the garden and L the length of the garden (longer side) as in the figure attached. The red sides on the figure represent the parts of the garden that require fencing.

L is also the measure of a vertical side of the garden, because a rectangle consists only of vertical and horizontal sides.

We know that the barn is parallel to the longer (vertical) side, so only one of the vertical sides L of the rectangle needs fencing. The other two parts correspond to the horizontal sides of the rectangle so they require 2W feet of fencing. Altogether, the 120 ft of fencing enclose the L+2W ft of the fence, then 120=L+2W. Because the longer side is twice the width, we have that L=2W, so 120=2W+2W=4W. From here, W=30 ft and L=2(30)= 60ft.

padilas [110]

Answer:

3. An additional month of product use is associated with an additional 0.85 inch of growth.

Step-by-step explanation:

Given that a company is testing a product which is intended to make hair grow faster. One of the test subjects started with a hair length of 8.2 inches

After a year of using the product, the test subject's hair measured 18.4 inches. If the growth rate was constant during the trial period, then we find that for 12 months hair growth is 10.2 inches

Assuming constant growth for 1 month growth is 10.2/12 = 0.85 inches

i.e. for every month additional use the growth would be 0.85 inches.

The equation relating hair growth and months would be

Hair size = No of months used *0.85 + 8.2

So correct option is

3. An additional month of product use is associated with an additional 0.85 inch of growth.
