Answer:

Perimeter = 21 units

Volume = 110 cubic units

Step-by-step explanation:

Let the center of circle be (x,y).

(x+2)^{2} +(y-7)^{2} = (x)^{2}+(y+2)^{2}

4x - 18y = - 45

(x)^{2}+(y+2)^{2}=(x-2)^{2}+(y-2)^{2}

4x + 8y = 4

x + 2y = 1

Solving these 2 equations,

4 - 26y = -45

y = \frac{49}{26}

x = \frac{-36}{13}

radius = 3.35

Perimeter = 2\pi r = 21 units

Volume of cylinder = \pi r^{2} h

We have to add the volumes of the cylinders.

Volume of smaller cylinder = \pi \times 2^{2} \times 2 = 8\pi

Volume of larger cylinder = 27 \pi

Total volume = 35\pi = 110 cubic feet

A new, trendy department store is experiencing exponential growth across America. The chain began in 2004 when it opened 16 stor
QveST [7]
The equation is y=16(1.35)ˣ.

This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time.  For our problem, a is 16; b is 0.35 (35%=35/100=0.35).  This gives us the equation above.

Tom's school report must be more than 12 pages, he writes at the rate of a half a page a day.
soldi70 [24.7K]

Answer:

24 days (or more)

Step-by-step explanation:

I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?

Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.

Therefore, Tom needs at least 24 days to write his school report.
