Billy anderson is choosing between two fitness centers. Center A charges $495 per year for unlimited use of all facilities. Cent

er B charges a $25 sign up fee, a $15 monthly fee, and $5 per aerobics class. If billy goes to aerobics once a week, which club is least expensive for him to use for a year

Let's compare the cost of both the centers.

<u>Cost of Center A:</u>

One time charge of $495 in one year.

<u>Cost of Center B:</u>

  • Flat $25 dollar sign up fee
  • $15 per month, so 15*12=180 dollars a year
  • $5 per aerobic class, so 5*52=260 dollars a year (given that Billy goes to class once a week) (<em>Note: There are 52 weeks in a year</em>)

Total cost = 25+180+260=465 dollars

Hence, Center B would cost 495-465=30 dollars cheaper.


ANSWER: Least expensive club for Billy to use for a year is Center B

It would be cheaper for Billy Anderson to go to Center B because the 25 dollar sign up fee plus the 15 dollars a month for 12 months plus 5 dollars a week for 52 weeks is 25+180+260 is 465 so he would save $30 dollars

A spherical balloon is inflated with gas at the rate of 500 cubic centimeters per minute. How fast is the radius of the balloon
zmey [24]

Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

V = \frac{4\pi r^3}{3}

Applying implicit differentiation, the rate of change is given by:

\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}

In this problem, we have that:

\frac{dV}{dt} = 500, r = 70

Hence the rate of change of the radius is given as follows:

\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}

19600\pi\frac{dr}{dt} = 500

\frac{dr}{dt} = \frac{500}{19600\pi}

\frac{dr}{dt} = 0.0081

The radius is increasing at a rate of 0.0081 cm per minute.

Please help! Correct answer only, please! Find the product A · A^t A. B. C. D.
Karolina [17]

Answer: choice A

Step-by-step explanation:

the transposed matrix would be

5 3

2 -1

so

5*5+2*2=29

3*5+2*-1=13

5*3-2*-1=13

3*3+-1*-1=10

which gives us the answer

29 13

A circle is circumscribed around a square and another circle is inscribed in the square. If the area of the square is 9 in2, wha
lesantik [10]

Answer:

√2:1

Step-by-step explanation:

First we need to know that the length of the side of the square is equal to the diameter of the inscribed circle i.e

L = di

Given the area of the square to be 9in², we can get the length of the square.

Area of a square = L²

L is the length of the square.

9 = L²

L = √9

L = 3in

Hence the length of one side of the square is 3in

This means that the diameter of the inscribed circle di is also 3in.

Circumference of a circle = π×diameter of the circle(di)

Circumference of inscribed circle = π×3

= 3π in

For the circumscribed circumscribed circle, diameter of the outer circle will be equivalent to the diagonal of the square.

To get the diagonal d0, we will apply the Pythagoras theorem.

d0² = L²+L²

d0² = 3²+3²

d0² = 9+9

d0² = 18

d0 = √18

d0 = √9×√2

d0 = 3√2 in

Hence the diameter of the circumscribed circle (d0) is 3√2 in

Circumference of the circumscribed circle = πd0

= π(3√2)

= 3√2 π in

Hence, ratio of the circumference of the circumscribed circle to the one of the inscribed will be 3√2 π/3π = √2:1
