Answer:

Note :

The perimeter is :  AB + BC + CA


AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180

AB = √(36×5) = 6√5 units

same method for :  BC ; CA   ..........

Answer:

Perimeter = 32.44 unit

Area of triangle = 30 unit²

Step-by-step explanation:

By distance formula distance between (a,b) and (c,d) is \sqrt{(c-a)^2+(d-b)^2}

So, we have

      AB=\sqrt{(16-2)^2+(2-8)^2}=15.23\\\\BC=\sqrt{(16-6)^2+(2-2)^2}=10\\\\AC=\sqrt{(2-6)^2+(8-2)^2}=7.21

Perimeter = 15.23 + 10 + 7.21 = 32.44 unit

We have s=\frac{15.23+10+7.21}{2}=16.22

Area of triangle=\sqrt{s(s-AB)(s-BC)(s-AC)}=\sqrt{16.22(16.22-15.23)(16.22-10)(16.22-7.21)}=30

Area of triangle = 30 unit²

These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?

Write the equation of a linear function for which f=(-4)=0 and f=(0)=-2
densk [106]

Answer:

y = -0.5x - 2

Step-by-step explanation:

equation: f(x) = mx + b

f(-4) : -4m + b = 0  ...(1)

f(0):   0m + b = -2            b = -2   ... plug in (1)

-4m - 2 = 0

m = - 1/2 = - 0.5

linear equation: y = -0.5x - 2
