Answer:

About 28.26 inches.

Step-by-step explanation:

The formula for circumfrence is c = 2(pi) * r.

We know that r = 4.5 (because the diameter is 9 inches).

So, the equation is c = 2(pi) * 4.5

Let's solve:

c = (2*3.14) * 4.5

c = 6.28 * 4.5

c = 28.26

Therefore, the final answer is 28.26 inches.

Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.

Write the equation for a line that is perpendicular to the line 8x-4y=12 and passes through the orgin
Delicious77 [7]

Answer:

y = - \frac{1}{2} x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 8x - 4y = 12 into this form

Subtract 4x from both sides

- 4y = - 8x + 12 ( divide all terms by - 4 )

y = 2x - 3 ← in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}

Since the line passes through the origin then c = 0

y = - \frac{1}{2} x ← equation of perpendicular line

yawa3891 [41]

Answer:C. 3000 ft

Step-by-step explanation:

First, find the radius of the circumference.

By dividing 1000 ft by 2, which is 500, and that is the radius.

Then you multiply the radius by 3, which is 1500.

Finally, you want the circumference, to find the circumference you need to multiply the radius by 2, which is 3000 ft.

That’s it.

Can someone help me with this
elena-s [515]

Answer:

3^14

Step-by-step explanation:

Taking a look at the question, try to break it down into these general steps:

1. Identify the base number. Are they the same? In this case, the base number is 3 so they are the same.

2. Recall the rules when multiplying exponents. In this case, multiplying exponents across will end up being 9+5.

3. Rewrite the equation as 3^(9+5). This should give you 3^14
