Answer:
Step-by-step explanation:
Just find the inverse cosine of 1 which is 0 degrees.
Answer:
x = -4, x = 1
Step-by-step explanation:
x^2 + 3x - 4 = 0
4 and -1 add to 3 and multiply to -4.
(x+4)(x-1) = 0
Separate these by the Zero Product Property.
x+4 = 0
x-1 = 0
Solve.
x = -4
x = 1
Answer:
The distance is 2.33 π
Step-by-step explanation:
First we have to calculate the perimeter of the circle with the following formula:
r = 14in
c = π * 2r
Now we replace the value of r
c = π * 2 * 14
c = π * 28
c = 28π
Now we have to multiply it by 30/360 which is the fraction that represents the arc over the entire circumference
28π * 30/360 = 2 1/3 π = 2.33 π
