Answer:
324π in.³
Step-by-step explanation:
The figure is a cone and a half sphere.
V = (1/3)πr²h + [(4/3)πr³]/2
V = (1/3)π(36 in.²)(15 in.) + (2/3)π(216 in.³)
V = [180π + 144π] in.³
V = 324π in.³
Answer:
-- Another point
Step-by-step explanation:
Given
Solving (a): Another point
Substitute 1 for x and 8 for f(x) in
Remove absolute bracket
Substitute 8 for a in
Let x = -1
Remove absolute bracket
So, another point is:
Solving (b): The value of a
This has been solved in (a) above
Answer:
20% decrease
Step-by-step explanation:
step one- subtract
30-24=6
step 2 is divide
amount of change from step one÷beginning val
6/30=.2
convert to %
.2=20%
it is a decrease as the value 30 went down to 24
It would stay the same. Hope this helps :)
