Mathematics

The equation for circumference is
c = 2r\pi
Since you have the diameter you can either divide the diameter (d) by two to get the radius (r), or you can divide two from the equation to give you
c = d \pi
So the circumference is 33*pi meters, approximately 103.62 meters

Which of these is the standard form of the following function?
Nady [450]

Answer:

A

Step-by-step explanation:

Given

f(x) = - 9(x + 5)² + 4 ← expand parenthesis using FOIL

     = - 9(x² + 10x + 25) + 4 ← distribute parenthesis by - 9

     = - 9x² - 90x - 225 + 4 ← collect like terms

     = - 9x² - 90x - 221 ← in standard form

Allen is buying a video that originally cost $49.He has a 10%-off coupon and will have to pay a 6% sales which expression will c
Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{100-10}{100}×\frac{100+6}{100}

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{90}{100}×\frac{106}{100}

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax=  $46.746

Hence, the correct answer is $46.746

-5 = b -2/3<br><br> b= __<br><br> Please help!
Inga [223]

Answer:

b = -4\frac{1}{3}

or

b = -\frac{13}{3}

Step-by-step explanation:

-5 = b - \frac{2}{3}

Add \frac{2}{3} to both sides of the equation to get rid of the "- \frac{2}{3}" on the right side.

-5 + \frac{2}{3} = b - \frac{2}{3} + \frac{2}{3}

Simplify

-4\frac{1}{3} = b

b = -4\frac{1}{3}

or

b = -\frac{13}{3}
