Answer:
C = 226.08 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
We know the radius is 36 and pi = 3.14
C = 2 * (3.14) * 36
C = 226.08 inches
Answer:
x = ±√11 +2
Step-by-step explanation:
Given in the question an equation,
x²- 4x - 7 = 0
Step 1
take 7 to the right side of equation
x²- 4x = 7
Step 2
To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b, the coefficient of x
2ab = -4x
2xb = -4x
b = -2
Step 3
Take square of b and add it to each side of the equation.
x²- 4x + (-2)²= 7 + (-2)²
x²- 4x + 4 = 7 + 4
x²- 4x + 4 = 11
Step 4
Factor the perfect trinomial square
(x−2)² = 11
Step 5
take square root on both sides
√(x−2)² = √11
(x-2) = ±√11
x = ±√11 +2
H= ut -16 t^2
h = 144(2) - 16 (4)
= 288 - 64 = 224
Answer:
-3/2
Step-by-step explanation:
Use formula (y2 - y1)/(x2 - x1)
Take points (-8, 4) and (-6, 1)
Use the formula:
y2 = 1
y1 = 4
x2 = -6
x1 = -8
(1 - 4)/(-6 - (-8))
= -3/(-6 + 8)
= -3/2
