Answer: $1.50/cookie
Step-by-step explanation:
Cookies = x
Water = y
5x + y = $8.75
y = 1.25
Plug in y-value into equation:
5x +1.25 = 8.75
5x = 8.75 - 1.25
5x = 7.50
x = 7.50/5
x = $1.50 for 1 cookie.
Answer:
1/10
Step-by-step explanation:
4+6+3+5+2=20
so there are 2 brown M&M's
=2/20
= 1/10
I hope this helps a little bit.
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.
