Answer:

see below

Step-by-step explanation:

We need to find the volume of the cylinder

V = pi r^2 h

V = pi * 7^2 * 5

V = pi (245)

V = 245pi ft^3

Using 3.14 as an approximation for pi

V =769.3 ft^3

If we use the pi button

V = 769.6902001 ft^3

PLEASE HELP!!!!
Lisa [10]

Answer:

x = - 3 with multiplicity 2

Step-by-step explanation:

f(x) = (x - 3)(x + 3)(x + 3) = (x - 3)(x + 3)²

Equating each factor to zero and solving for x

x - 3 = 0 ⇒ x = 3 with multiplicity 1

x + 3 = 0 ⇒ x = - 3

x + 3 = 0 ⇒ x = -3

Thus x = - 3 has multiplicity of 2

The fact that the factor is squared gives the multiplicity

(x + 3)³ has root - 3 of multiplicity 3

ASHA 777 [7]

Answer:

(-6,4)

Step-by-step explanation:

The equations are:

x^2+4y^2=100\\4y-x^2=-20

Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:

4y-x^2=-20\\x^2=4y+20\\-------\\x^2+4y^2=100\\4y+20+4y^2=100

Now we can solve for y:

4y+20+4y^2=100\\4y^2+4y-80=0\\y^2+y-20=0\\(y+5)(y-4)=0\\y=4,-5

So plugging in y = 4 into an equation and solving for x, we have:

x^2=4y+20\\x=+-\sqrt{4y+20} \\x=+-\sqrt{4(4)+20} \\x=+-\sqrt{36} \\x=6,-6

So y = 4 corresponds to x = 6 & x = -6

The pairs would be

(6,4) & (-6,4)

<u><em>we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.</em></u>

help pls The circumference of the hub cap of a tire is 80.1 centimeters. Find the area of this hub cap. Use 3.14 for pi. Use pen
Liula [17]

Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well

Step-by-step explanation:

First, you must find the radius

<em>80.1 ÷ 3.14 = 25.5</em>

<em>25.5 ÷ 2 = 12.75 <---- radius</em>

Then from that, you find the area

A=πr²

<em>12.75² = 162.5</em>

<em>162.5 × 3.24 = 510.25</em>

<em></em>

<em>Hope this was helpful!</em>
