Find the exact area of the circle with the given radius. r = 4.5 m

1 answer:

Alexus [3.1K]2 years ago

The area of a circle is Pi * R^2 (or R * R).
Since we have our radius, R, we can solve.
With our given answer choices, we do not need to multiply R by Pi, instead we will square R, as that's our only option.
4.5 x 4.5 = 20.25.
Our area is now 20.25Pi.
Your answer is C.) 20.25Pi.
I hope this helps!

Your choir has 300 tickets to sell. You are responsible for distributing 10 tickets to each choir member to sell. A - Write an e

Goshia [24]

Answer:

Remaining tickets left to distribute, A = (300 - 10m)

Step-by-step explanation:

a) Let the number of choir members be m

Let the number of tickets remaining after the distribution be A

Each choir member is to get 10 tickets each.

Number of tickets to be given to the members = 10m

original number of tickets = 300

So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)

b) The independent variable in this expression is m (the number of choir members)

And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)

Hope this Helps!!!

Find the equation of the line that is perpendicular to LaTeX: y=-\frac{1}{5}x+3y = − 1 5 x + 3 and goes through the point (4, -3

Elenna [48]

Answer:

$y=5x-23$

Step-by-step explanation:

step 1

Find the slope of the line that is perpendicular to the given line

we have

$y=-\frac{1}{5}x+3$ -----> given line

The slope of the given line is

$m=-\frac{1}{5}$

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal

therefore

The slope of the line that is perpendicular to the given line is

$m=5$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=5\\point\ (4,-3)$

substitute

$-3=5(4)+b$

solve for b

$b=-23$

therefore

$y=5x-23$
