Find the equation of the line with Slope = 8 and passing through (3,28). Write your equation in the form

kvasek [131]

Answer:

y = 8x + 4

Step-by-step explanation:

y=mx+b

m=8

y = 8x + b

We just need to find b. B is where the line intersects the y- axis. On the y-axis by definition, the x-coordinate =0 but that is not helpful now...

Let's re write and try to solve for b. That means write as b = ...

y = 8x + b

b = y - (8x)

Substitute for x and y the numbers of the coordinates of the given point (3,28):

b = y - (8*x)

b = 28 - (8*3)

b = 28 - 24

b = 4

So the answer is y = 8x + 4

Rounded to the nearest hundred cubic meters, what is the total capacity (cone and cylinder) of the storage container?

hichkok12 [17]

The picture in the attached figure

we know that
the total capacity of the storage container=volume of a cone+volume of cylinder

step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³

step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³

total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³

the answer is
1400 m³
