Answer:
Percentage change in interest groups between 1959 (500) & 1995 (600) = 20%
Step-by-step explanation:
Percentage change = <u>Change ie (New - Old) </u> x 100
Old value
Suppose -
Number of interest groups in 1959 = 500
Number of interest groups in 1995 = 600
Percentage change = [ (600 - 500) / 500 ] x 100
( 100 / 500 ) x 100 = 20%
Answer:
12
Step-by-step explanation:
x² - 16x + 60 = -12
→ Add 12 to both sides
x² - 16x + 72 = 0
Answer:
Step-by-step explanation:
arc between cars = 360°/25 = 14.4°
θ = 14.4° × π/180 ≅ 0.2512 radian
r = 150/2 = 75 ft
s = rθ = 75×0.2512 = 18.84 ft
area of circle = πr² = 75²π ≅ 17,662.5 ft²
area of sector = 17,662.5/25 = 706.5 ft²
Answer:
12
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√[4 - (-8)]² + (10 - 10)²
√(12)² + (0)²
√144 + 0
√144
=12
Answer:
Step-by-step explanation:
The formula primarily used for finding the derivative of a square root is
d/dx(x^n) = nx^(n - 1)
and so:
(d/dx)(x^(1/2)) = (1/2)x^(1/2 - 1), or:
1
(1/2)x^(-1/2), or, in radical form, ---------
2√x
