Answer:
785.4
Step-by-step explanation:
The formula to find the surface area of a cylinder is
2* pi* radius* height + 2* pi* 2radius.
2( 3.14) (5) (20)= 628
2 (3.14* 5*5)= 157
628+ 157= 785.
Answer:
(x - 8)(x + 3)
Step-by-step explanation:
x² - 5x - 24
Consider the factors of - 24 which sum to give the coefficient of the x- term (- 5)
The factors are - 8 and + 3 , since
- 8 × + 3 = - 24 and - 8 + 3 = - 5
Use these factors to split the x- term
x² - 8x + 3x - 24 ( factor the first/second and third/fourth terms )
= x(x - 8) + 3(x - 8) ← factor out (x - 8) from each term
= (x - 8)(x + 3) ← in factored form
Answer:
7 is a 8 is b 9 is a 10 is c....
You divide 3600/20,ad you will get 180 square feet.
Good models are expected to reflect the number of books sold between zero and w numbers of weeks where w is defined.
<h3>What is a model?</h3>
A mathematical model is an equation that serves as a representation of a real life situation. It could be used for investigative or predictive purposes as required.
The following are all domains for which the average rate of change could be a good measure for the number of books sold:
- 0 ≤ w ≤ 2
- 0 ≤ w ≤ 7
- 0 ≤ w ≤ 10
Hence, good models are expected to reflect the number of books sold between zero and w numbers of weeks where w is defined.
