Answer:
(b) 80/3π in³
Step-by-step explanation:
The volume of a circular cone is given by ...
V = 1/3πr²h . . where r is the radius (half the diameter) and h is the height
Your cone has r = 4 inches and h = 5 inches, so its volume is ...
V = (1/3)π(4 in)²(5 in) = 80/3π in³
The volume of the cone is exactly (80/3)π cubic inches.
Given situation: => 18 times 4 to the second power plus (9 minus 3) to the second powerLila answers 324 while Rob answers 360 in the given problem or equation.Now, let's try to solve it to know who got the correct answer:=> 18 x 4^2 + (9 - 3)^2, since we have a parenthesis in our equation, we need to solve it first=> 18 * 4^2 + (6)^2=> 18 * (4* 4) + (6 * 6)=> (18 * 16) + 36=> 288 + 36=> 324<span>Thus Lila got the correct answer</span>
Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
Answer:
x
Step-by-step explanation:

Answer:
option B
Given : |x + 4| < 5
A. –5 > x + 4 < 5
B. –5 < x + 4 < 5
C. x + 4 < 5 and x + 4 < –5
D. x + 4 < 5 or x + 4 < –5
In general , |x|< n where n is positive
Then we translate to -n < x < n
|x + 4| < 5
5 is positive, so we translate the given absolute inequality to
-5 < x+4 < 5
So option B is correct
