Answer:
Required A. radious of the cylinder is B. there is no change in radious due to change in height.
Step-by-step explanation:
Given volume of the cylinder is 728, that is we know for a cylinder with height h and radious r, volume V is,
A. To find radious of the cylinder :
which is the required radious.
B. To find change of radious due to change in height :
If the height h of the cylinder change to then radious,
From (1) we get,
Squaring both side we get,
Which shows that change of height dosen't effect on radious.
Answer:
The factored form of the equation is (x + 4)(x – 6) = 0.
Answer:
i think it weak positive im not sure
Step-by-step explanation:
Answer:
y = 1/2x^2 - 2x + 1
Step-by-step explanation:
The equation of the parabola in vertex form is y = 1/2 (x - 2)^2 - 1. By finding the vertex at (2,-1) we plug in the point into the formula y = a(x-h)^2 + k. To convert it to standard form like the equations listed, multiply through the distributive property to clear the parenthesis.
y = 1/2 (x-2)(x-2) - 1
y = 1/2 (x^2 - 4x + 4) - 1
y = 1/2x^2 - 2x + 2 - 1
y = 1/2x^2 - 2x + 1
The sum of the interior angles is 180°
