Given the function, f(x)= 5(x+4)^3/2, which of the following represents its y-intercept
1 answer:
Answer:
The y-intercept is at (0,40).
Step-by-step explanation:
y = f(x)= 5(x+4)^3/2
We find the y-intercept but putting x = 0 and evaluating:
y = f(0) = 5(0 + 4)^2^3/2
= 5*4^3/2
= 5*(√4)^3
= 5 * 2^3
= 5*8
= 40.

Answer:
< 1 = 112 degrees
< 2 = 68 degrees
Step-by-step explanation:
< 1 = x
< 2 = x - 44
x + x - 44 = 180
2x = 180 + 44
x = 224/2
x = 112
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
