Answer:

272.6

Step-by-step explanation:

This is an isosceles triangle with base of 21 and sides of 28.

<u>Area formula</u>

A = 1/2bh

<u>Find height:</u>

h = $\sqrt{28^2 - (21/2)^2} = \sqrt{673.75} = 25.96$

A = 1/2(25.96)(21) = 272.6 (rounded)

Which expression is equivalent to (m8n-4) 1/4

ser-zykov [4K]

Answer:

D. $\dfrac{m^2}{n}$

Step-by-step explanation:

I assume this is your problem:

$(m^8n^{-4})^{\frac{1}{4}}$

If so, then this is the solution.

$(m^8n^{-4})^{\frac{1}{4}} =$

$= m^{8 \times \frac{1}{4}} n^{-4 \times \frac{1}{4}}$

$= m^2 n^{-1}$

$= \dfrac{m^2}{n}$

Find the values of m&n if x

Sever21 [200]

The values of m and n from the given equation are 1/4 and -2

<h3>Polynomial functions</h3>

Given the polynomial function below

f(x) = mx^4+2x^3-3x^2+nx-4

If the zeros are 2 and -2, hence;

0 = 16m+16-12+2n-4
0 = 16m-16+12-2n-4

_______________
16m+2n = 0
16m - 2n = 8

Subtract

2n+2n = -8
4n = -8

n = -2

Substitute for "m'

16m + 2(-2) = 0
16m = 4

m = 1/4

Hence the values of m and n from the given equation are 1/4 and -2
