Answer:
9π meters
Step-by-step explanation:
SInce 6π is the circumference of the circle, 6π would be the diameter.
We need to then convert 6π into the radius which we can do by dividing 6π by 2 to get 3π.
The formula for the area of a circle is πr^2. Plug in the previous result for the radius to get the following:
π3^2
9π
Answer:
<u>The correct answer is A. 12 minutes.</u>
Step-by-step explanation:
Let's solve for y, when x = 12, as follows:
y = 175 - 15x
y = 175 - 15 * 12
y = 175 - 180
y = - 5
This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.
<u>The correct answer is A. 12 minutes.</u>

Answer:
Below.
Step-by-step explanation:
Substitute x = 3 into each polynomial and see if the value of the polynomial is zero. If it is zero then x-3 is a factor.
Try number 1:
a(x) = x^3 - 2x^2 - 4x + 3
a(3) = 3^3 - 2(3)^2 - 4(3) + 3
= 27 - 2(9) - 12 + 3
= 27 - 18 - 12 + 3
= 9 - 18 - 9
= 27 - 27
= 0
So a(x) has (x-3) is a factor of a(x)
The other 3 polynomials are solved in the same way.
