You have no more than $65 to spend after paying your bills. You want a drink that costs

-BARSIC- [3]

Answer: B

Step-by-step explanation: You have no more than $65 which means you will want to spend equal to or less. Since you have $65, you will be able to spend up to that amount but you will not be able to spend any more than that. So, you will need to make sure the final price remains under or equal to your amount.

Which of the following is the solution to the differential equation dP/dt+P=10 with the initial condition P(0)=4

Ber [7]

Answer:

Option C. $P=10-6e^{-t}$

Explanation:

<u>1. Separate variables:</u>

$\dfrac{dP}{dt}+P=10\\ \\ \\ \\\dfrac{dP}{dt}=-P+10\\ \\ \\ \dfrac{dP}{-P+10}=dt$

<u></u>

<u>2. Find the indefinite integrals</u>

$-\ln{(10-P)}=t+C$

<u></u>

<u>3. Solve for P</u>

$10-P=e^{-t+C}\\ \\ 10-P=Ke^{-t}\\ \\ P=10-Ke^{-t}$

<u></u>

<u>4. Use the initial condition, P(0) = 4, to find K:</u>

4 = 10 - K(e⁰)

4 = 10 - K

K = 10 - 4

K = 6

<u></u>

<u>5. Substitute K = 6 into the integrated equation:</u>

$P=10-6e^{-t}$

That is the option C.

What is the value of y for the line that has a slope of 1 and goes through the points (-4, y) and (-2, 8)?

Pavel [41]

Answer:

y = 6

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (-4,y) and (-2,8). Substitute m = 1 and solve for y.

$m = \frac{y_2-y_1}{x_2-x_1}\\\\ 1 = \frac{y-8}{-4--2}\\\\ 1 =\frac{y-8}{-2}\\\\-2=y-8\\\\6=y$
