To make a triangle 2 of the sides must be the same length
Answer:
double the radius.
Step-by-step explanation:
Quadruple means 4 times. So you want to make the volume 4 times larger than it currently is.
This can be a little nasty because both numbers are the same.
V = 1/3 pi * r^2 * h
V = 1/3 3.14 * 4.8^2 * 4.8
V = 115.75296
Now if you double the radius, the volume becomes 4 times larger (or it should)
V= 1/3 * 3.14 * (9.6)^2 * 4.8
V = 463.012
Did that make the original volume larger?
115.75296 * 4 = 463.012 rounded.
Answer:
-2x^2 + 4k - 10k^2 + 15
Step-by-step explanation:
-1/4(8k^2 - 16)-10k^2 + 15
-1/4 × 4 (2x^2 - 4k)-10k^2 +15
-(2x^2 - 4k)-10k^2 +15

Step-by-step explanation:
it is able of being taken on the go ... but what does this have to do with math ?? anyways plz mark brainliest if u felt like i helped the most:)
Answer:
![x^{3}-3x^{2}-5x+15](https://tex.z-dn.net/?f=x%5E%7B3%7D-3x%5E%7B2%7D-5x%2B15)
Step-by-step explanation:
The roots of the given polynomial are: ![-\sqrt{5}, \sqrt{5}, 3](https://tex.z-dn.net/?f=-%5Csqrt%7B5%7D%2C%20%5Csqrt%7B5%7D%2C%203)
Since,
are the roots of the polynomial, according to the factor theorem,
would be the factors of the polynomial.
Since we have the factors of the polynomial, we can multiply them to get the desired polynomial.
Let the polynomial be represented by P(x), so
![P(x) = (x - (-\sqrt{5}))(x-\sqrt{5})(x-3)\\\\ P(x)=(x +\sqrt{5})(x-\sqrt{5})(x-3)\\\\ P(x)=(x^{2}-(\sqrt{5} )^{2})(x-3)\\\\ P(x)=(x^{2}-5)(x-3)\\\\ P(x)=x^{3}-3x^{2}-5x+15](https://tex.z-dn.net/?f=P%28x%29%20%3D%20%28x%20-%20%28-%5Csqrt%7B5%7D%29%29%28x-%5Csqrt%7B5%7D%29%28x-3%29%5C%5C%5C%5C%20P%28x%29%3D%28x%20%2B%5Csqrt%7B5%7D%29%28x-%5Csqrt%7B5%7D%29%28x-3%29%5C%5C%5C%5C%20P%28x%29%3D%28x%5E%7B2%7D-%28%5Csqrt%7B5%7D%20%29%5E%7B2%7D%29%28x-3%29%5C%5C%5C%5C%20P%28x%29%3D%28x%5E%7B2%7D-5%29%28x-3%29%5C%5C%5C%5C%20P%28x%29%3Dx%5E%7B3%7D-3x%5E%7B2%7D-5x%2B15)
The polynomial represented by P(x) has the given roots.
