Step-by-step explanation:
Slope of the mountain
= Rise in height / Run in distance
= (4215ft - 3720ft) / 5 mi
= 495ft / 5mi
= 99ft/mi. (C)
Important: Use the symbol "^" to denote exponentiation:
<span>x3 – 9x2 + 5x – 45 NO
</span><span>x^3 – 9x^2 + 5x – 45 YES
Look at the first 2 terms. They can be rewritten as x^2(x-9). Then look at the last 2 terms. They can be rewritten as 5(x-9). So, x-9 is the common factor here. Thus, the original expression becomes:
(x^2-5)(x-9).
Note that x^2-5 can be factored, so that the final 3 factors are:
(x-sqrt(5)), (x+sqrt(5)), (x-9).</span>
If one inch represents 15 feet, then:
2 inches represent:
2 * 15 = 30 feet
1 2/3 inches represent:
1 2/3 * 15 =
= 5/3 * 15 =
= 75/3 =
= 25 feet
So the real area of the court is 30 * 25 = 750 square feet.
Answer:
C) 44
Step-by-step explanation:
Put 8 where x is and do the arithmetic.
f(8) = 6·8 -4 = 48 -4
f(8) = 44
