Health club A charges $60 yearly enrollment fee and $2 per visit. Health club B charges $20 yearly enrollment fee and &4 per

atroni [7]

Answer:

20 visits

Step-by-step explanation:

The club that charges $40 more for enrollment charges $2 less per visit. The savings on visits is equal to the extra enrollment charge when the number of visits is 40/2 = 20.

For 20 visits, the cost at both clubs is the same.

If you let v represent the number of visits, ...

A = 60 +2v . . . . cost at club A

B = 20 +4v . . . . cost at club B

A = B ⇒ 60 +2v = 20 +4v . . . . . . costs are the same for "v" visits

40 = 2v . . . . . . . subtract 20+2v from both sides

40/2 = v = 20 . . . . . . same as "word solution" above

Pls help!!! evaluate the function for x=m/4

EastWind [94]

Plug in m/4 into the equation:

$8 (\frac{m}{4})^{2} - 4(\frac{m}{4})$

Solve the parentheses in the equation:

$\frac{m}{4}^{2} = \frac{m}{4} \times \frac{m}{4} = \frac{m^{2}}{16}$
$8 \times \frac{m^{2}}{16} = \frac{8m^{2}}{16} = \frac{m^{2}}{2}$

$4 \times \frac{m}{4} = \frac{4m}{4} = m$

Your equation should now look like this:

$\frac{m^{2}}{2} - m$

The answer is D.

What is the rate of growth, as a percent, for the following function? D(x)=23(1.0032)x

maks197457 [2]

I will assume you meant D(x)=23(1.0032)^x, if so:

The growth rate as a percentage is 100(.0032)=0.32% (about 1/3 of 1%)
