Answer:

25.92 cubic centimeters

Step-by-step explanation:

The formula for volume of a prism is

A(prism) = base*height

The formula for the base of a triangular prism is

A(triangle) = 1/2 b*h

                 = 1/2 3.6*2.4 = 4.32 cm^2

Plug that back in.

A(prism) = base*height

              = 4.32 * 6 = <u>25.92 cubic centimeters</u>

Write the product as a sum: 14cos(39x)sin(19x)
charle [14.2K]

Recall that

sin(<em>a</em> + <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) + cos(<em>a</em>) sin(<em>b</em>)

sin(<em>a</em> - <em>b</em>) = sin(<em>a</em>) cos(<em>b</em>) - cos(<em>a</em>) sin(<em>b</em>)

Adding these together gives

sin(<em>a</em> + <em>b</em>) + sin(<em>a</em> - <em>b</em>) = 2 sin(<em>a</em>) cos(<em>b</em>)

To get 14 cos(39<em>x</em>) sin(19<em>x</em>) on the right side, multiply both sides by 7 and replace <em>a</em> = 19<em>x</em> and <em>b</em> = 39<em>x</em> :

7 (sin(19<em>x</em> + 39<em>x</em>) + sin(19<em>x</em> - 39<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) + sin(-20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

7 (sin(58<em>x</em>) - sin(20<em>x</em>)) = 14 cos(39<em>x</em>) sin(19<em>x</em>)

A one-year membership to a gym costs $725. The registration fee is $125, and the remaining amount is paid monthly. Define a vari
wel

Given :

A one-year membership to a gym costs $725.

The registration fee is $125.

To Find :

How much new members pay each month.

Solution :

Remaining fee = Total fee - Registration fee

R = $( 725 - 125 )

R = $600

Amount of fee paid monthly is :

C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50

Therefore, monthly fee is $50.

Hence, this is the required solution.
