Answer:

Step-by-step explanation:

First what you want to do is find the slope.

-3+3/1+3

0/4

slope=0

now you want to write the equation in point-slope form

y+3=0(x-1)

simplify

y+3=0

subract 3 from each sides

y=-3 is the answer

whatever x is, y is equal to -3

I learned this so many times but I forgot how to do it exactly.

But looking at this, you can already determine that y is equal to -3 so couldn't you use that as an answer.

The circumference of an NBA-approved basketball is 29.6 in. Given that the radius of Earth is about 6400 km, how many basketball
ella [17]

Answer:

167,886,383 basketballs

Step-by-step explanation:

We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:

Perimeter = Pi*diameter [m]\\Where Pi = 3.14

Earth's diameter is simply radius*2. It means:

P= 3.14*6400*2 = 40,192 [km]

On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.

Diameter of a basketball:

D= Perimeter /Pi [m]

We need to change units to fit in the international system.

29.6 in to cm = 29.6*2.54 = 75.184 [cm]

Then:

Diameter=75.184/3.14 = 23.94 [cm]

We have to convert earth's perimeter in km to cm:

Equator=40192[km]*100000=4,019,200,000 [cm]

Finally, dividing total earth's circumference by a basketball diameter:

Totalbasketballs=4,019,200,000/23.94= 167,886,383 [basketballs]
