For perpendicular lines, m1m2 = -1 or m2 = -1/m1.
Line y = x + 1 has a slope of 1, Hence, the perpendicular line will have a slope of -1/1 = -1
Required equation is y - y1 = -1(x - x1)
y - 2 = -(x - (-2))
y - 2 = -(x + 2)
y - 2 = -x - 2
y = -x - 2 + 2
y = -x

What is the volume of the right prism with height h=14 cm, if the base of the prism is a triangle ∆ABC with side AB = 9 cm and a

Lina20 [59]

Answer:
volume of prism = 378 cm³

Explanation:
The volume of the right prism can be calculated as follows:
volume of prism = area of base * height of prism

1- getting the area of base:
Our base is a triangle, this means that:
area = 0.5 * base * height
We have:
base = 9 cm
height = 6 cm
Therefore:
area of base = 0.5 * 9 * 6
area of base = 27 cm²

2- getting the volume:
volume of prism = area of base * height of prism
volume of prism = 27 * 14
volume of prism = 378 cm³

Hope this helps :)

There was a blizzard. Snow was falling at the rate of 4 1/2 inches per hour. If the snow keeps acclimating how long will 5 feet

Archy [21]

5 feet = 60 inches
4 1/2 inches = 1 hour
60 inches = 1 ÷ 4 1/2 x 60
= 13 1/3 hours

If the snow keeps accumulating, it would take 13 1/3 hours for 5 feet of snow to accumulate.
