<em>Your answer is D. 16(1)=16+18=34. 16(2)=32+18=50. 16(3)=48+18=66. And finally, 16(4)=64+18=82.</em>

Look carefully at the table. Each time x increases by 1, y increases by 16.
Thus, the slope of the line describing this situation must be 16.

Note that if x = 1, y = 34. If you decrease x by 1 to 0, then y decreases by 16 to 18. Thus, the y-intercept is (0,18).

Choose the correct answer choice based upon this info.

Solve for e <br> 9e-7=7e-11

Scilla [17]

Answer:

e = -2

Step-by-step explanation:

9e-7=7e-11

Subtract 7e from both sides

9e-7e -7=7e -7e-11

2e -7 = -11

Add 7 to each side

2e -7+7 = -11+7

2e = -4

Divide each side by 2

2e/2 = -4/2

e =-2

C
Because .75 times 9 would give you the price of the books and then you would have to add C, the amount left to get to 20.

Got a calc 1 question,

belka [17]

$v=\dfrac h{3x}\implies\dfrac{\mathrm dv}{\mathrm dt}=\dfrac{3x\frac{\mathrm dh}{\mathrm dt}-3h\frac{\mathrm dx}{\mathrm dt}}{3x^2}$

By the chain rule,

$\dfrac{\mathrm dh}{\mathrm dt}=\dfrac{\mathrm dh}{\mathrm dx}\dfrac{\mathrm dx}{\mathrm dt}$

We have

$h(x)=4e^{2x-6}-x^2+5\implies\dfrac{\mathrm dh}{\mathrm dx}=8e^{2x-6}-2x$

and we're given that $x$ changes at a constant rate of $\frac{\mathrm dx}{\mathrm dt}=0.2$ thousand people per minute, which means

$\dfrac{\mathrm dv}{\mathrm dt}=\dfrac{3x\left(8e^{2x-6}-2x\right)\left(0.2\frac{\text{thousand people}}{\rm min}\right)-3h\left(0.2\frac{\text{thousand people}}{\rm min}\right)}{3x^2}$

At the moment $x=4$ thousand people are in the park, we have $h(4)=4e^2-11$ , so we find

$\dfrac{\mathrm dv}{\mathrm dt}=\dfrac{12\left(8e^2-8\right)-3(4e^2-11)}{240}\dfrac{\text{thousand people}}{\rm min}=\dfrac{7(4e^2-3)}{80}\dfrac{\text{thousand people}}{\rm min}$

or approximately 2.324 thousand people per minute.
