Answer:
We need to calculate the height of the 6mi by 8mi by 10mi triangle. In order to do this we first must calculate its area.
To calculate the area we need to use Heron's formula.
We then learn that the area is 24.
Since triangle area = .5 * base * height
then height = 2 * area / base
height = 2 * 24 / 10
height = 4.8
Triang Prism Surface area = 2 * Triangle Area + height * (a + b + c)
Triang Prism Surface area = 2 * 24 + 4.8 * (6 + 8 + 10)
Triang Prism Surface area = 48 + 4.8 * 24
Triang Prism Surface area = 163.2

Answer:
y = x - 5
Step-by-step explanation:
Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points
(0, - 5) and (4, - 3)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 5) and (x₂, y₂ ) = (4, - 3)
m = =
=
The line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = f(x) = x - 5 ← equation of line
