(x-5)(x^2+4x-2)<br><br> PLEASE HELP
ANEK [815]

Answer:

Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10

Step-by-step explanation:

Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.

x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2

Simplify terms.

x^3 − x^2 − 22x + 10

I hope this helps.

Given a soda can with a volume of 36 and a diameter of 4, what is the volume of a cone that fits perfectly inside the soda can?
Tomtit [17]
First we need to find the heigh of the soda can be rearanging the volume formula, V = pi * r^2* h. We can make that h =  \frac{V}{pi * r^2} We know that V is 36 and radius is half of the diameter, so radius is 2. h =  \frac{36}{pi * 2^2}
h =  \frac{36}{pi * 4}
h = 2.87

Now, we can use the height to figure out the volume of a cone. The volume of a cone is V = pi * r^2 *  \frac{h}{3}
R is 2 again and h is 2.87
V = pi * 2^2 *  \frac{2.87}{3}
pi * 4 * .96
12.56*.96 = 12.0576
So a cone with a volume of 12.0576 is the largest that will fit into the soda can
