Answer:
First, I think the right formula is:
![V(t) = 100,000(1-\frac{t}{60} ),20\leq t\leq 60](https://tex.z-dn.net/?f=V%28t%29%20%3D%20100%2C000%281-%5Cfrac%7Bt%7D%7B60%7D%20%29%2C20%5Cleq%20t%5Cleq%2060)
A) We first derive the formula given above:
![V'(t)=-\frac{100000}{60}](https://tex.z-dn.net/?f=V%27%28t%29%3D-%5Cfrac%7B100000%7D%7B60%7D)
V'(t) represent the drain rate of the tank volume.
B) the units is: gallons/time
C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
Answer:
it would be 37.69 square yards the answer that was given is off by .01
Step-by-step explanation:
you multiply 12 times pi (3.14) = 37.69
Answer:
![\displaystyle 90° = m∠2](https://tex.z-dn.net/?f=%5Cdisplaystyle%2090%C2%B0%20%3D%20m%E2%88%A02)
Step-by-step explanation:
In every rhombus, when you have two diagonal segment bisectors, you will always have a circumcentre showing all midpoints of both segment bisectors, plus, it measures 90° all around, so with that being said, you have your answer.

Answer:
C. P'(-4,-7), Q'(-8,-7), R'(-3,3).
Step-by-step explanation:
When a shape is reflected over a line y=x, the values in the coordinates are just swapped.
P(-7,-4) becomes P'(-4,-7)
Q(-7,-8) becomes Q'(-8,-7)
R(3,-3) becomes R'(-3,3)
The answer is P'(-4,-7), Q'(-8,-7), R'(-3,3).
