Answer:

Step-by-step explanation:
Given a geometric sequence, the nth term of the geometric sequence is obtained by using the formula:

If the eleventh term, 
and the common ratio, r=-2.
Then:

The explicit formula for the sequence is:

Sphere Surface Area = <span> 4 • <span>π <span>• r²
50.27 = 4 * PI * r^2
</span></span></span>
<span>50.27 / (4 * PI) = r^2
</span>
<span>
<span>
<span>
4.0003594946
</span>
</span>
</span>
= r^2
r = sq root
(<span>
<span>
<span>
4.0003594946)
radius = </span></span></span>
<span>
<span>
<span>
2.0000898716
</span>
</span>
</span>
So the diameter =

<span>
<span>
4.0001797433
</span>
</span>
</span>
or it is roughly 4 feet
Answer:
Step-by-step explanation:
13=3x+4
subtract 4 from both sides
9=3x
divide by 3
x=3
Quadrilateral that is a parallelogram

Answer: 
-------------------------------------------------------------------------------------------------------------
Given: 
Find: 
Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7. We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.
<u>Plug in the values</u>
<u>Distribute</u>
<u>Add 8 to both sides</u>
Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.
