How would you solve for a) & b) with a calculator? I have a TI-89 Titanium. At time t=0, a tank contains 38 gallons of water. Beginning at t=0, water flows into the tank at a rate of E(t) = 12tsin(π/4t) gallons per minute, and water leaks out of the tank at a rate of L(t) = 6t2/ (t+2) gallons per minute. a) How many gallons of water are in the tank at time t = 2 minutes? b) What is the rate of change in the volume of water in the tank at t = 2 minutes? (Include appropriate units)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

b and c

step-by-step explanation:

4+4+2x

or

2x+8
