Question 1
Because the period is 2π, and the amplitude is 1obtain
f(x) = sin(x)
Because the horizontal shift is π, obtain
f(x) = sin(x - π)
Because the vertical shift is -4, obtain
f(x) = sin(x - π) - 4

Answer: 1. f(x) = sin(x - π) - 4

Question 2
The radius is 36/2 = 18 in.
1 revolution (360°) is the circumference, which is
2π(18) = 36π in
When the revolution is 62°, the distance traveled is
(62/360)*(36π) = (31/5)π in

Answer: 3. (31π)/5

Question 3.
Consider f(x) = 3cos(2x-π) - 1
f(0) = 3cos(-π) - 1 = -4
f(π/2) = 3cos(0) - 1 = 2
Rate of change = (2+4)/(π/2) = 12/π

From the graph, the rate of change of g(x)  is
3/(π/2) = 6/π

Consider h(x) = sin(x) - 4
h(0) = 0 - 4 = -4
h(π/2) = 1 - 4 = -3
Rate of change = (-3+4)/(π/2) = 2/π
Therefore h(x) has the smallest rate of change

Answer: h(x)

Answer:

C

Step-by-step explanation:

y=mx+b is the equation for a line, where m is the slope.

For a line to be parallel to each other, they must share the same m value.

In your equation, y=6x+8, 6 is the slope

The only answer that shares that slope of 6 is C.

<em>I hope this helps! :)</em>

Most of the men's shoes in the data set cost more than women's shoes.

Step-by-step explanation:

From what I could tell it can't be The price of men's shoes has a higher interquartile range than that of women's shoes. becuse that's false what looks to fit is Most of the men's shoes in the data set cost more than women's shoes.   since on the graph more of the mens  vaules are bigger

Carmencita is 12 years old and she is saving for a car. She wants to have $5,000 by the time she is 16 years
kati45 [8]

Answer:

$ 22.22

Step-by-step explanation:

Let

P = amount to save per week

B = expected accurate at 16 years = $5000

r = APR = 3.9% = 0.039

n = numbers of week in a year = 52weeks

t = 16 - 12 = 4 years terms of savings.

Using,

P = (B * r/n)/{(1 + (r/n))^(nt) -1}

P = (5000 * 0.039/52)/{(1 + (0.039/52))^(52 * 4) -1}

P = $22.22

Use function notation to represent the area of a circle whose circumference is 148cm
ANTONII [103]
148^²/4pi
=1742.83

2 pi r=148
r=148/2pi
Now
Area=pi r^²
Pi×(148)^²/4pi^²
=148^²/4pi
