Find the equation of the line that contains the given point and has the given slope-

mylen [45]

Answer:

y-5 = -3x

y = -3x+5

Step-by-step explanation:

We can use the point slope form of the equation

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y-5 = -3(x-0)

y-5 = -3x

We can change it to slope intercept form y= mx+b by adding 5 to each side

y-5+5 = -3x+5

y = -3x+5

A wedge of cheese is shaped like a triangular prism. The wedge of cheese is 7 inches tall. The base of the cheese is shaped like

Gala2k [10]

Answer:

193 in

Step-by-step explanation:

Volume of a triangular prism:

The volume of a triangular prism is the base area multiplied by the wedge, that is:

$V = A_bw$

The base area is one half times the triangle base times it's height, so:

$V = 0.5*b*h*w$

The wedge of cheese is 7 inches tall.

This means that $w = 7$

The base of the cheese is shaped like a triangle with a base of 11 and a height of 5 inches.

This means that $b = 11, h = 5$

Volume:

$V = 0.5*b*h*w = 0.5*11*5*7 = 192.5$

Rounding, approximately 193 in.
