Answer:
see below
Step-by-step explanation:
We assume you want the graph of ...

A graphing calculator or spreadsheet is useful for this.
__
You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.
r at 0° = 8
r at 30° ≈ 7.05
r at 45° ≈ 6.19
r at 60° ≈ 5.33
r at 90° = 4
r at 120° = 3.2
r at 135° ≈ 2.96
r at 150° ≈ 2.79
r at 180° ≈ 2.67
Answer:
5026.55in²
Step-by-step explanation:
Area = πr^2
radius (r) is half of the diameter, hence the radius is 40 inches
So after plugging that in, the equation should look like
Area = π(40)^2
A = 1600π ≈ 5026.55
The units for this is in² so just add that in the end
Answer:
m = 3/4
Step-by-step explanation:
A(3, 7)
B(7, 10)
As we move from A to B, we see x increasing by 4 to 7 and y increasing by 3 to 10. Thus the slope is
m = rise / run = 3/4
Answer:
≈ 5
Step-by-step explanation:
<u><em>You can use the Pythagorean Theorem to solve this:</em></u>

<u><em>Now plug in the numbers into the formula:</em></u>

36 +
= 64
<u><em>Subtract 36 from both sides:</em></u>
36 +
= 64
-36 -36
_________
= 28
<em><u>Square both sides:</u></em>

b = 5.29
b ≈ 5
Answer:
y=0
Step-by-step explanation:
The asymptote of exponential equations is where is plateaus/flattens out. it will never actually touch it. Here it flattens out on the y-axis.
