X would have to equal 10. This would be the answer because the numbers have to be proportional. To do that all you have to do is do 12/8. Then you get 1.5. Then you do the same for 15. Do 15/1.5 and get 10.
In the 
-
plane, the base has equation(s)
which is to say, the distance (parallel to the -axis) between the top and the bottom of the ellipse is
so that at any given , the cross-section has a hypotenuse whose length is 
.
The cross-section is an isosceles right triangle, which means the legs occur with the hypotenuse in a ratio of 1 to 
, so that the legs have length 
. Then the area of each cross-section is
Then the volume of this solid is
The graph of csc(x) = 1/sin(x) has asymptotes at the points where sin(x) = 0, which happens for x = 2nπ and x = (2n + 1)π, where n is any integer.
This means
• f(x) = 2 csc(x) has the same asymptotes, at x = 2nπ and x = π + 2nπ
• g(x) = 4 csc(2x) has asymptotes at 2x = 2nπ and 2x = π + 2nπ, or equivalently x = nπ and x = π/2 + nπ
• h(x) = 4 csc(3x) has asymptotes at 3x = 2nπ and 3x = π + 2nπ, or x = 2nπ/3 and x = π/3 + 2nπ/3
• j(x) = 2 csc(x/2) has asymptotes at x/2 = 2nπ and x/2 = n + 2nπ, or x = 4nπ and x = 2π + 4nπ
so none of these choices are correct.
Answer: Tom is 3 years old then Brad
Step-by-step explanation:
<em>Tom's age minus Brad's age</em>.
13 - 10 = 3
I hope this helps you!
