Answer:

2 - (-4)

4 + (-2)

5 - (-5)

6 - (-1)

Step-by-step explanation:

- 1 + (-5) = -1 - 5 = -6

2 - (-4) = 2 + 4 = 6

-3 + 2 = -1

4 + (-2) = 4 - 2 = 2

5 - (-5) = 5 + 5 = 10

6 - (-1) = 6 + 1 = 7

gayaneshka [121]

Answer:

156.86

Step-by-step explanation:

We start by dividing 136.40 by 100 so we can figure how much 1 percent,(1.364) once we have that we multiply by 15 (20.46), we add that to the total

Hi! how do i find surface area of a cylinder? for some reason i can’t get the right answer
asambeis [7]
SA=2\pi r^2+2\pi rh

Use the formula above to find the surface area of a cylinder.

For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:

\begin{gathered} r=\frac{d}{2} \\  \\ r=\frac{16mi}{2}=8mi \end{gathered}

Surface area:

\begin{gathered} SA=2\pi(8mi)\placeholder{⬚}^2+2\pi(8mi)(6mi) \\ SA=128\pi mi^2+96\pi mi^2 \\ SA=224\pi mi^2 \end{gathered}Then, the surface area of the given cylinder is: 224π square miles

ANSWER THIS CORRECTLY FOR BRAINLIEST!!!!<br><br> This is 8th grade<br> algebra btw
gulaghasi [49]

Answer:

V = 2143.57

Step-by-step explanation:

To find the volume of a sphere you need to use this formula:

V = \frac{4}{3}\pi r^{3}

r = radius

Solve:

You need the radius from the diameter. Divide 16/2 which is

8.

V = \frac{4}{3}(3.14) 8^{3}

V = 2143.57

50 points! I understand A. and B. but I would really appreciate help with C.
FromTheMoon [43]

Answer:

51.72\text{ cells per hour}

Step-by-step explanation:

So, the function, P(t), represents the number of cells after t hours.

This means that the derivative, P'(t), represents the instantaneous rate of change (in cells per hour) at a certain point t.

C)

So, we are given that the quadratic curve of the trend is the function:

P(t)=6.10t^2-9.28t+16.43

To find the <em>instanteous</em> rate of growth at t=5 hours, we must first differentiate the function. So, differentiate with respect to t:

\frac{d}{dt}[P(t)]=\frac{d}{dt}[6.10t^2-9.28t+16.43]

Expand:

P'(t)=\frac{d}{dt}[6.10t^2]+\frac{d}{dt}[-9.28t]+\frac{d}{dt}[16.43]

Move the constant to the front using the constant multiple rule. The derivative of a constant is 0. So:

P'(t)=6.10\frac{d}{dt}[t^2]-9.28\frac{d}{dt}[t]

Differentiate. Use the power rule:

P'(t)=6.10(2t)-9.28(1)

Simplify:

P'(t)=12.20t-9.28

So, to find the instantaneous rate of growth at t=5, substitute 5 into our differentiated function:

P'(5)=12.20(5)-9.28

Multiply:

P'(5)=61-9.28

Subtract:

P'(5)=51.72

This tells us that at <em>exactly</em> t=5, the rate of growth is 51.72 cells per hour.

And we're done!
