Answer:

43.5 unit^2.

Step-by-step explanation:

Area of the triangle

= 1/2 * base * height

= 1/2 * AB * AC.

AB = √ [(6-1)^2 + (6-8)^2] = √29

AC = √ [(8 - (-7))^2 + (1 - (-5)^2] = √261

So the area = 1/2 * √29  * √261

                    = 43.5

Gina has 6 yards of ribbon. She cuts the ribbon into pieces that each measures three fourths yard. How many pieces of three four
ziro4ka [17]

Given

Gina has 6 yards of ribbon.

She cuts the ribbon into pieces that each measures three fourths yard.

Find out  how many pieces of three fourths yard does Gina have

To proof

let the number of pieces of the ribbon be x.

As given in the question

Gina has of ribbon = 6 yards

She cuts the ribbon into pieces that each measures three fourths yard

Than the equation becomes

x\times \frac{3}{4} = 6

x = \frac{6 \times 4}{3}

solving the above equation

we get

x = 2 × 4

x = 8

Gina have 8 pieces of three fourths yard

Hence proved

What is an equation for the translation of (x – 2)2 + (y + 1)2  = 16  by 3 units left
Akimi4 [234]
Answer: ( x + 1)² + (y - 4)² = 16

Explanation:

1) The given equation,  ( x - 2)² + (y + 1)² = 16, represents a circumference with center (2,-1) and radius √16 = 4.

1) The translation will not modify the radius of the circunference, siince translations are rigid transformations.

2) The translation 3 units to the left and 5 units upward certainly will move the center of the circunference.

This is how:

(x,y) → (x - 3, y + 5)

(2, -1) → (2 - 3, - 1 + 5) = (- 1, 4)

3) Then, keeping the same radius and being the center (-1,4), the equation of the circumference after the translation will be:

( x + 1)² + (y - 4)² = 16 ← answer
