Which of the following functions gives the radius, r(v), of a conical artifact that is 20 inches tall as a function of its volum

nalin [4]

By calculus or elementary geometry, we know that the formula for the volume of a cone, given pi (the constant), its height h and its radius r is:
$V=pi*h*r^2/3$
Lets solve this relation for the radius:
$3V=pi*h*r^2
$
$\frac{3V}{pi*h} =r^2$
$\sqrt{\frac{3V}{pi*h}} = r$
Now we have found a general formula that gives us the radius of a cone, given its volume and height. We need only substitute height (20in) and pi=3.14 to get the numerical equation: r=0.2185* $\sqrt{V}$

A line passes through the points(-9,9) and has a slope of 2/3

Anni [7]

ANSWER

y = 2/3x + 15

Explanation:

Equation used: y - y1 = m( x - x1 )

y - 9 = 2/3 ( x - -9 )

y - 9 = 2/3x + 6 ( distribution )

y - 9 = 2/3x + 6 ( add 9 to 6 )

y = 2/3x + 15

I don't understand this question.

Answer: .75g + 4 = 7 [remove spaces where necessary]

Step-by-step explanation: $4 is the flat rate for a helmet, so we add that into the equation. Since "g" represents one group of pitches and it costs 75¢, we add it into the equation as .75g. On the other side of the equal sign we put the amount of money spent, in this case 7 - to find out how many groups of pitches he bought we just solve the equation. In this case g = 4.
