The area of a trapezoid is calculated with the help of the formula, Area of trapezoid = ½ (a + b) h, where 'a' and 'b' are the bases (parallel sides) and 'h' is the perpendicular height.
Let m be the rental cost for movies.
Let v be the rental cost for video games.
We have the following system of linear equations:
3m + 5v= 38
6m + 2v = 26
Multiply the first equation by 2
6m + 10v = 76
6m + 2v = 26
Subtract the both equations.
8v = 50
Divide both sides by 50.
v = 6.25
Plug this value into any of the two equations to solve for m.
You get m=2.25
The rental cost for a movie is
<h2>$2.25</h2>
The rental cost for a video game is
<h2>$6.25
</h2>
Have an awesome day! :)
Answer:
Period = pi
Angular frequency = 2
Amplitude = 5
Midline is the line y = 3
Step-by-step explanation:
A sinusoidal wave is written in the general form as:
f(x) = A*cos(w*x) + C
Where:
- A is the amplitude.
- w is the angular frequency, this is equal to 2*pi/T
where T is the period.
- y = C is the midline.
Then in the equation:
f(x) = 5*cos(2*x) + 3
- 5 is the amplitude.
- 2 is the angular frequency (in the image is called frequency, but this quantity must be in radians/time, while the normal frequency is only in Hz)
- We know that the angular frequency is equal to 2*pi/T, whit this eqation we can find the period:
2 = 2*pi/T
T = 2*pi/2 = pi
pi is the period.
- y = 3 is the midline.
The perimeter is 46cm
you find the width by dividing the area by the length and then add the length and width times 2 to get the perimeter
