Help plz this is tough for me

Volume of triangular prism = 216 in³

Step-by-step explanation:

Given:

Length of prism = 9 in

Height of prism = 6 in

Base of prism = 8 in

Find:

Volume of triangular prism = ?

Computation:

⇒ Volume of triangular prism = 1/2[lbh]

⇒ Volume of triangular prism = 1/2[9 in × 8 in × 6 in]

⇒ Volume of triangular prism = 1/2[432 in³]

⇒ Volume of triangular prism = 216 in³

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
