Planet Fitness charges a one-time application fee of $50 plus $30 per session for a

Mathematics
1 answer:
Vsevolod [243]3 years ago
6 0

Answer:

When the number of sessions is equal to 10, the total cost is the same in the two plans

Step-by-step explanation:

Let

y ---> the total cost

x ---> the number of sessions

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

Planet Fitness

we have

The slope is equal to

m=\$30\ per\ session

The y-intercept or initial value is equal to

b=\$50

substitute

y=30x+50 ----> equation A

Gold's Gym

we have

The slope is equal to

m=\$10\ per\ session

The y-intercept or initial value is equal to

b=\$250

substitute

y=10x+250 ----> equation B

Equate equation A and equation B

30x+50=10x+250

solve for x

30x-10x=250-50\\20x=200\\x=10

therefore

When the number of sessions is equal to 10, the total cost is the same in the two plans

The diameter of the base of the cone measures 8 units. The height measure 6 units. What is the volume of the cone?
ivolga24 [154]

Answer:

The  volume of the cone is  100.48 units³ approximately

Step-by-step explanation:

To find the volume of a cone with a diameter of 8 unit   and height of 6 units, we will follow the steps below;

first, write down the formula for calculating the volume of a cone

v= πr²\frac{h}{3}

where v is the volume of the cone

r is the radius    and h is the height of the cone

from the question given, diameter d = 8 units  but d=2r    which implies  r=d/2

r=8/2 = 4 units

Hence r= 4 units

height = 6 units

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

v= πr²\frac{h}{3}

v ≈ 3.14 × 4² × 6/3

v  ≈ 3.14 × 16 × 2

v ≈ 100 .48 units³

Therefore the  volume of the cone is  100 .48 units³ approximately

(cos2a *cos 4a+ sin 2a*sin 4a)/sin4a
lyudmila [28]

Answer:

Step-by-step explanation:

(cos 4a*cos 2a+sin 4a*sin 2a)/sin 4a

=[cos (4a-2a)]/sin 4a

=(cos 2a)/sin 4a

=(cos 2a) /(2 sin 2a cos 2a)

=1/(2 sin 2a)

=1/2 csc 2a
