Answer: V=200.96m^3

Step-by-step explanation:

I believe you're trying to find its volume.

Formula: V=\frac{1}{3}\pi r^2h

V=\frac{1}{3}(3.14)(4m)^2(12m)\\ V=200.96m^3

Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
snow_lady [41]

Answer:

(\frac{1}{2}, \frac{-1}{2})

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: (x_{1}, y_1) and (x_2, y_2)

The midpoint formula would be (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}).

2) Based on this, we can easily find the midpoint of AB.

  • -3 would be x_1\\
  • -5 would be y_1
  • 4 would be x_2  
  • the next 4 would be y_2

3) With this information, we can solve for the midpoint.  

(\frac{-3+4}{2}, \frac{-5+4}{2}) --> (\frac{1}{2}, \frac{-1}{2}) --> This is your answer.

Sure.  From those choices, the only one that makes sense is that he
didn't perform enough trials.  Technically, you can't expect the experimental
probability to match the theoretical probability until you've rolled it an infinite
number of times.

I have a hunch that even for only 60 trials, such a great discrepancy between
theory and experiment is beginning to suggest that the cubie is loaded.  But
you really can't say.  You just have to keep trying and watch how the numbers
add up.

I just don't know where to start. I'm doing Algebra 2 stuff with sohcahtoa.

Hello!

As you can see, 22 is the opposite angle. We are looking for the adjacent angle. Let's just call it x. Using SOH CAH TOA, we see that the tangent is the opposite divided by the adjacent side. Let's use that.

tan54≈1.38

This gives us the equation below.

1.38=22/x

Let's solve this equation for x.

1.38x=22

x=22/1.38

x=15.94

Therefore, the length of the shadow is about 15.94 meters.

I hope this helps!
