Coordinates (-3, 5), ( -3, 8), and (2, 5). The triangles was dilated by a scale favtor of 3. What is the area of the dilated tri
Otrada [13]

Answer:

The area of the triangle is 7.5 unit²

Step-by-step explanation:

Here we have the coordinates given as

(-3, 5) (-3, 8) and (2, 5)

Let us call the points A = (-3, 5)

B = (-3, 8) and

C = (2, 5)

Therefore the lengths of the sides of the triangle are

AB = a =  \sqrt{(-3-(-3))^2+(5-8)^2} =  3

AC = b = \sqrt{(-3-2)^2+(5-5)^2} =  5

BC = c = \sqrt{(-3-2)^2+(8-5)^2} =  \sqrt{34}

Therefore the Area can be derived from Heron's formula which is

A =  \sqrt{s\times (s-a)\times (s-b)\times (s-c)} where s = semi perimeter or (a + b + c)/2

Therefore, plugging the values, we get

s =   (3 + 5 + √34)/2 = 6.9155≈6.92

A =  \sqrt{6.92\times (6.92-3)\times (6.92-5)\times (6.92-\sqrt{34} )} = 7.499≈7.5.

What is the average rate of change of f over the interval -4≤x≤5
Ira Lisetskai [31]

The average rate of change over the interval is 2/9

<h3>How to determine the average rate of change?</h3>

The interval is given as:

-4 ≤ x ≤ 5

From the table, we have:

f(5) = 4

f(-4) = 2

The average rate of change is then calculated as:

m = \frac{f(5) - f(-4)}{5 --4}

This gives

m = \frac{4 - 2}{5 +4}

Evaluate

m = \frac{2}{9}

Hence, the average rate of change over the interval is 2/9
