Answer:
It is 75 Hope this helps
Step-by-step explanation:
It is the second one down
480⁰= 360⁰+120⁰
or
480⁰-360⁰=120⁰
You need to remove all 360 angles, sometimes it can be more than one in it.
Coterminal angle is 120⁰.
Answer:
(-4 , 1)
Step-by-step explanation:
We know that the turning point of any parabola is in its vertex. The x of the vertex can be calculated with the formula:
x = -b/2a
In our case b = 8, a = 1, so:
x = - 8/2 = -4
We plug this value into our original equation and find the y of the vertex:
(-4)^2 + 8(-4) + 17 = 16 - 32 + 17 = 1
Vertex = (-4 ; 1)
