Because they do if you times the radius by the diameter
These should be your answers though. I’ll help but still.
1.) I understand that quadratic functions are in the form of y = ax^2 + bx + c and that when placed on a graph, it will show a parabola.
2.) I have a question about how to get the vertex of a parabola and it’s vertex form.
Hope this is plausible enough.
Answer:
9.16 I think
Step-by-step explanation:
angle B =
(
) = 66.4 degrees to 1 decimal place
sin(66.4) = 
CD = 10sin(66.4)
CD = 9.16 to 2 decimal places
We need to find f(1)
f(1) means x=1
Now we look at the three inequalities and choose the one where x=1 satisfies
x<=-1 , -1<x<1 and x>=1
x=1 satisfies the inequality x>=1
so we use the third function to find f(1)

We plug in 1 for x and find f(1)
= 2 + 3 = 5
f(1) = 5
