The variation equation is p = kr^2
<h3>How to determine the variation equation?</h3>
The variables are give as:
Pressure = P
Radius= r
The direct variation from p to the square of r is represented as:
Express as an equation
p = kr^2
Where k represents the constant of variation
Hence, the variation equation is p = kr^2

Answer: C. (10, -10)
Step-by-step explanation:
Given
1) 2x-3y=50
2) 7x+8y=-10
Multiply both sides of 1) equation by 3.5
1) 3.5(2x-3y)=3.5×50
7x-10.5y=175
2) 7x+8y=-10
Subtract 2) equation from the 1)
(7x-10.5y)-(7x+8y)=175-(-10)
-18.5y=185
y=-10
x=10
(10, -10)
Hope this helps!! :)

Answer:
4.5 centimeters
Step-by-step explanation:
A = L * W
45 = 10 * W
W = 45/10
W = 4.5cm
<span>The point estimate obtained from a sample of which of the following sizes would most likely be closest to the actual parameter value is 150.
It is said that the higher the point estimate, the better. I think this deals with the confidence level of the sample derived from the population. The higher the confidence level, the closer the point estimate is to the actual parameter value.</span>
I dont understand the question.
