1.) What is the area of the triangle?
10.6 cm
10.6 cm
16 cm

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

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

1/2*qr*rs
