Answer: B
Explanation:
Use Pythagorean’s theorem to find it out:
A^2 + B^2 = C^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289
So these side lengths create a right triangle
Answer:
C
Step-by-step explanation:
If you have double functions, solve the one in the parentheses first.
in f(g(2)), solve g(2) first.
So, substitute 2 in the function.
g(x) = x^2 - 6x - 7
g(2) = 2^2 - 6(2) - 7 = -15
If you substitute -15 in f(g(2)), it becomes f(-15).
f(x) = x + 8
f(-15) = -15 + 8
f(-15) = -7
The answer for f(g(2)) is -7.
The biggest cone that can fit into a cube of side 3cm would have a diameter of 3 and height of 3, therefor if the volume of a cone = πr^2h*1/3, then:
Volume = π*1.5^2*3*1/3
= 2.25π
= 9π/4 cm^3
