Answer:
radius of 10.9254843 and height of 10.9254843
Step-by-step explanation:
The equation for the volume of a cylinder is V = 2 pi r h
If V (volume) = 750, find for r and h
(I'm just going to make the radius and height the same thing)
750 = 2 pi r r
375 = pi r^2
119.366207 = r^2
10.9254843 = r
Answer:
4.6.

Answer:
1/6 times the number cube wil land on 2
Step-by-step explanation:
The x-intercepts of the given quadratic function are -2 and 9.
What is a quadratic function?
A quadratic function is a function represented as, f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabolic curve represents the graph of a quadratic function.
A polynomial's highest degree reveals how many roots the polynomial has. The values for which the polynomial's numerical value is equal to zero are known as a polynomial's roots (also known as zeros of a polynomial). On a graph, the points where the polynomial's graph and the x-axis cross are the roots (x-intercepts).
Roots of the Quadratic Equation
Due to its degree of 2, a quadratic function can only have a maximum of two real roots. In order to find the roots of a quadratic equation, we equate its factors to 0. Thus, in this case, we have,
(x+2)*(x-9)=0
∴ x+2=0
⇒ x=-2
Similarly,
x-9=0
⇒ x=9
Hence, the x- intercepts of the given quadratic function come out to be -2 and 9.
