Answer: 16. f(1)=-2
17. f(-3)=1
18. x=0
19. x=-1 and x=1
Step-by-step explanation:
16. f(1)=-2
17. f(-3)=1
18. f(x)=-3
x=0 ==> f(0)=-3
19. f(x)=-2
x=-1 and x=1 ==> f(-1)=-2, f(1)=-2
Need mas
Find volume
- πr²h
- π(6)²(18)
- 36(18)π
- 2034.7cm³
Mass
As volume is same
Divide their densities to find ratio
- Gold /Silver
- 19.32/10.5
- 1.84 times heavier is gold
Answer:
It would be zero.
Step-by-step explanation:
Let's for example look at this list : 123456789
The mean is 5, and the median would also be 5.
Answer:
Step-by-step explanation:
The area of the base is given by the formula ...
A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
__
The volume is given by ...
V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 . . . . cubic units
