Answer:
A cone
Step-by-step explanation:
Plot the points
we have
A(0, 0), B(0, 5) and C(3, 0)
The figure is a right triangle
see the attached figure
so
When this shape is rotated about the y-axis, the 3-dimensional shape created will be a cone
where
AC is the radius of the base of cone
The radius is equal to r=AC=3 units
AB is the height of the cone
The height is h=AB=5 units
BC is the slant height of the cone
Applying Pythagoras Theorem
The answer is $12 an hour because 12 times 3 is 36 and half of 12 is 6 so add 6 to 36 and you get 42.
Answer:
13
Step-by-step explanation:
It would be 13 because you would square the 5 and 12 to get 25 + 144 which equals 169. Then you would take the square root of 169 which is 13. Hope this helps! :)

Answer: B) Complex numbers</h3>
Complex numbers are always in the form a+bi with 'a' and 'b' as real numbers.
If b = 0 and 'a' is nonzero, then a+bi = a+0i = a which is strictly a real number
If a = 0 and b is nonzero, then a+bi = 0+bi = bi indicating that the number is now purely imaginary
The answer is HC, HT, HH, CC, CT, CH, TC, TT, TH
