Answer:

A = 55.63 cm^2

Step-by-step explanation:

Let a,b,c be the lengths of the sides of a triangle. Heron's formula states that:

Area = √(p (p−a) (p−b) (p−c))    

where p is half the perimeter, or    

(a+b+c) / 2

So lets start by finding p:

(10.6 + 10.6 + 16) / 2

p = 18.6

Now lets substitute p and the other values into our equation:

A = √ (18.6 (18.6−10.6) (18.6−10.6) (18.6−16))

So let's plug this in to our calculators

A = √ (3095.04)

A = 55.633083682284 cm^2

I do not know how to do this need help
Diano4ka-milaya [45]

Remark

First of all you have to declare the meaning of g(f(x)) After you have done that, you have to make the correct substitution.

Givens

f(x) = 4x^2 + x + 1

g(x) = x^2 - 2

Discussion

What the given condition g(f(x)) means is that you begin with g(x). Write down g(x) = x^2 -  2

Wherever you see an x on either the left or right side of the equation, you put fix)

Then wherever you see f(x) on the right you put in what f(x) is equal to.

Solution

g(x) = x^2 - 2

g(f(x)) = (f(x))^2 - 2

g(f(x)) = [4x^2 + x + 1]^2 - 2

f(x)^2 =

4x^2 + x + 1

<u>4x^2 + x + 1</u>

16x^4 + 4x^3 + 4x^2

            4x^3  + x^2 +   x

<u>                         4x^2 + x  + 1</u>

16x^4 + 8x^3 + 9x^2 + 2x + 1

Answer

g(f(x)) = 16x^4 + 8x^3 + 9x^2 + 2x + 1 - 2

g(f(x)) = 16x^4 + 8x^3 + 9x^2 + 2x - 1
