The equation is a scientific law, Newton's Law of Gravity,
This is a pretty bad question. Newton's Law of Gravity is a mathematical model of gravitation, originally a theory, verified by observation, and now superseded by the General Theory of Relativity.
C is probably the best answer to this poor question.
Area of a circle = pi x r^2
200.96 = pi x r^2
200.96 = 3.14 x r^2
r^2 = 64
r = 8 inches
Hope this helps!! :)
Answer:
x = 24
Step-by-step explanation:
The formula for determining the sum of interior angles is:
Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.
The equation and answer above shows how to find x, which equals 24.
Answer:
24.75
Step-by-step explanation:
2x-11 + 6x-7 =180
8x-18=180
8x=198 /8
x=24.75
Answer:
The following steps are needed:
1. Find the function of AB with A(-3,2) and B(7,6)
y(AB) = mx + b. Calculate m = (y₂-y₁)/(x₂-x₁) = (6-2)/(7+3) = 4/10 → 2/5
y(AB) = (2/5).x + b. Calculate b; 6 = (2/5).(7) + b and b = 16/5
y(AB) = (2/5).x +16/5
2. calculate the function y(CD) = mx + bWe know already m = -5/2, since CD is perpendicular to AB and hence the product of their slopes = -1
y(CD) = -(5/2).x + b
We also know that y(CD) passes in the middle of AB, then let's calculate the coordinate of C, the midpoint of AB:x=(x₁+x₂)/2 and y=(y₁+y₂)/2)x= (-3+7)/2 and y=(2+6)/2x= 2 and y=4y(CD) = (-5/2).x +b4 = (-5/2).(2)+b and b = 9y(CD) =(-5/2)x + 9
x intercept when y = 0 → 0= (-5/2)x +9 → x= 18/5So x intercept (18/5,0)
So the answer is at point B.
