PLEASE ASAP:What is the product of all positive divisors of 10

xz_007 [3.2K]

The positive divisors of 10 are: 1, 2, 5, and 10 (these are the numbers that are divisible by 10 with a remainder of 0). To find the product, you just multiply them all together: 1 * 2 * 5 * 10 = 100.

A woman has a total of $9,000 to invest. She invests part of the money in an account that pays 7 % per year and

Volgvan

Answer:

Hi! I believe this is your answer:

$750

Step by step explanation:

interest + interest = total interest

0.08*x + 0.09*(9000-x) = 750 dollars

0.08x + 810 - 0.09x = 750

-0.01x = 750 - 810 = -60 ====> x = %28-60%29%2F%28-0.01%29 = 6000.

Final answer:

$6000 was invested at 8%. The rest 9000-6000 = 3000 dollars were invested at 9%.

Check. 0.08*6000 + 0.09*3000 = 480 + 270 = 750 dollars.

The area of a circular sun spot is growing at a rate of 1,200 km2/s.

Tpy6a [65]

A)

$\bf \textit{area of a circle}\\\\
A=\pi r^2
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2r\cfrac{dr}{dt}\implies \cfrac{dA}{dt}=2\pi r\cfrac{dr}{dt}\implies \cfrac{\frac{dA}{dt}}{2\pi r}=\cfrac{dr}{dt}\\\\
-----------------------------\\\\
\left. \cfrac{dr}{dt} \right|_{r=3000}\implies \cfrac{1200}{2\pi \cdot 3000}=\cfrac{dr}{dt}\\\\$

B)

$\bf A=\pi r^2\qquad A=490000\implies 490000=\pi r^2\implies \sqrt{\cfrac{490000}{\pi }}=r
\\\\\\
\left. \cfrac{dr}{dt} \right|_{r=\sqrt{\frac{490000}{\pi }}}\implies \cfrac{1200}{2\pi \cdot \sqrt{\frac{490000}{\pi }}}=\cfrac{dr}{dt}

lesya692 [45]

Answer:

Step-by-step explanation:

r = 14/2 = 7units

$Volume of sphere=\frac{4}{3}*\pi*r^{3}\\\\=\frac{4}{3}*3.14*7*7*7\\\\=1436.03cubic units\\\\Volume of cylinder=\pi*r^{2}*h\\\\=3.14*7*7*14\\\\=2154.04 cubic units$
