10 x .50 = 5

22.5 -5 = 17

I think this is correct.  Sorry if it isn't though!!!!!!

Find all the antiderivatives of the following function. Check your work by taking the derivative.
Rom4ik [11]

\int 10e^x dx = 10 \int e^x dx = 10 e^x + C

The first step, factoring out the constant 10, is due to the Constant Multiple Rule:

\int k \cdot f(x) dx = k \cdot \int f(x) dx

The derivative of the natural exponential function is itself! \frac{d}{dx} \left( e^x \right) = e^x. Reversing this,

\int e^x dx = e^x + C

The graph below shows the amount of money left in the school’s desk fund, f, after d desks have been purchased. A graph titled D
Vikki [24]

Answer:

$110

Step-by-step explanation:

The computation is shown below:

Provided that

Number of desk purchased    Fund Left $

           0                                   700

           1                                    590

           2                                   480

           3                                   370

           4                                   260

           5                                   150

           6                                    40

Now the Fund decreased while purchasing is

= 5 desks - 2 desks

= 3 desks

i.e

= $480 - $150

= $330

Now the amount of money left for decreased the desk fund is

= \frac{Fund\ decreased }{number\ of\ desk\ decreased}

= \frac{\$330}{3\ desk}

= $110

Andrew fish tank holds 144 gallons of water. To clean the tank, he drains the water at a rate the water at a rate of 6 gallons p
Kobotan [32]

Answer:

8 minutes

Step-by-step explanation:

Since the level of the tank needs to be at two-thirds its original level, then this means that Andrew needs to drain only one-third of the fish tank. Therefore the amount of time it would take can easily be solved with this 2-step equation...

6t = 144 * \frac{1}{3} .... first multiply the right side of the equation

6t = 48   ... next divide both sides by 6

t = 8

Finally, we can see that it will take Andrew 8 minutes to drain the tank to two-thirds of its original level.
