I took an test, and had the question and this was the answer.
Answer:
12.57 or 12.56637 when it isnt rounded up
Step-by-step explanation:
V=πr^2 h/3 is the formula to find the volume
so if u plug in the numbers
V=π 2^2 3/3 which equals 12.56637
For non-right triangles you must use the "Law of Cosines" and then, the "Law of Sines" to solve this<span>.
a= </span> 8.25m<span>
b=</span> 10.4m<span>
c= </span>3.16m
∠<span>A= UNKNOWN
</span>∠<span>B= UNKNOWN
</span>∠<span>C=UNKNOWN
Law of Cosines:
c</span>²= a²+b²-2abCos(C)
(3.16)²= (8.25)²+(10.4)²- 2(8.25)(10.4)(cos(C))
9.9856 = 68.0625 + (108.16) - (171.6)(cos(C)
9.9856 = 176.2225- 171.6 cos C
-166.2369= - (171.6(cosC))
cosC= 0.968746503
<span>Take the inverse cosine of that to get the measure of angle C
</span>∠C= 15.95813246°
<span>
Now Use law of sines to find </span>∠B:
(take the inverse sine to get the measure of ∠B)
∠B= 60.8040992°<span>
Answer:The angle measures approximately 60.80</span>°.<span>

Answer:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

I hope help you and thanks for heart and rate my answer
Answer:
y = 2
Step-by-step explanation:
-13y + 33 = 7
add -13y to each side of the equation:
33 = 13y + 7
subtract 7 from each side:
13y = 26
divide both sides by 13:
y = 2
