Answer:
52 students were in each bus
Step-by-step explanation:
475-7=468÷9=52 so 52
Answer:
Initial Value=15
Rate of change=15/10=1.5
Equation: y=1.5x+15
Step-by-step explanation:
y=ax+b
y=1.5x+b
15=1.5(0)+b
b=15
Answer:
"changes the period to pi"
Step-by-step explanation:
f(t) = Sin(t),
Here, t is the period, by definition.
Multiply t by a number that is GREATER THAN 1, makes the period shorter and compressed.
Multiplying t by a number that is between 0 and 1 makes the period expanded.
For the first, if we multiply the period by a, the period becomes ![\frac{2\pi}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7Ba%7D)
Since the problem tells us to multiply by 2, we know the period becomes compressed and becomes :
![\frac{2\pi}{2}=\pi](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7B2%7D%3D%5Cpi)
Third answer choice is right.
Slope: (y2-y1)/(x2-x1)
(8-2)/(1+1) = 6/2 = 3
The slope is 3
