X= -b over 2a = --6 over 2×1=3
y=3²-6(3)-7=-16
vertex is (3,-16)
axis of symmetry is 3
Answer:
-3
Step-by-step explanation:
It would just be -12+9=-3.
Answer:b = 48.4017
Explanation:For this question, we will use the sine rule to get the missing side b. The sine rule is shown in the attached image.
We are given that:
a = 31
measure angle A = 38°
measure angle B = 74°
Substitute in the relation as follows:
sinA/a = sinB/b
sin(38) / 31 = sin(74) / b
b = [sin(74)] / [sin(38) / 31]
b = 48.4017
Hope this helps :)
Answer:Length and angle measure
Step-by-step explanation:
The length measure is the distance along the curve (arc) and the angle measure is the angle that the arc makes with the center of the circle.
