Answer:
0.5kg
Step-by-step explanation:
5kg/2=2.5kg
2.5kg/5=0.5kg
When f(x) = g(x), it is the coordinates when the two graphs intersected.
The answer is read off from the graph.
Answer: x = -3.5 and x = -0.5 (Answer 1)
We have two questions, but we need to find the volume of the spherical tank first.
So the formula we will use to find the volume is:
(4/3)πr³=V
Let's fill in the information we have and solve. We will be using 3.14 for pi.
(4/3)(3.14)6³
(4/3)(3.14)(216)
4.1867×216
I'll be using the repeating decimal for 4.1867, I rounded to 7, but there is a repeating 6.
904.32
So the volume is 904.32 yards³ (or 904.78 if using the full pi)
We have to multiply the volume by 7.15.
904.32×7.15
6,465.89
It will cost $6,465.89 to fill the tank with the liquid.
