If a cylindrical tank holds 100,00 gallons of water which can be drained from thebottom of the tank in an hour, then Torricelli’
tatyana61 [14]

Answer:

First, I think the right formula is:

V(t) = 100,000(1-\frac{t}{60} ),20\leq t\leq 60

A) We first derive the formula given above:

V'(t)=-\frac{100000}{60}

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.

What is an equation parallel to y=3x-5
choli [55]

Answer:

ANY line that has a slope of 3, and any y intercept other than -5.

Step-by-step explanation:

Parallel lines have the same slopes, but different y intercepts.

So, it would be ANY line that has a slope of 3, and any y intercept other than -5.

here are a few examples:

y=3x-17

y=3x+4

y=3x+3293248032843209.3432492384032984032984023840398249082

y=3x+5

y=3x-1

y=3x

Please help with this!!!!!
anastassius [24]

Answer:

y = -2x + 7.

Step-by-step explanation:

The slope is (5-7)/1-0 = -2 ,

Checking with other values: slope = (- 3 - 7)/ (5-0) = -10/6 = -2.

So the function is  -2x + c   where c is  some constant.

Plugging in the point (0, 7):

7 = -2(0) + c

c = 7.

So the answer is y = -2x + 7.
