Answer:
(-5,-13)
Step-by-step explanation:
Find the vertex of the parabola y=1/5x^2+2x−8.
In this equation a=15 and b = 2.
x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5
Substitute −5 into the equation y=1/5x^2+2x−8
y=1/5(−5)^2+2(−5)−8
y=5−10−8
y=−13
The vertex is (−5 , −13)
<span>First find the central angle A in degree.
Perimeter circle 2Pi*R --> 360 deg
Arc A = 14.13 --> x deg
(360*14.13)/2Pi*R = 5086.8/37.68 = 135 deg
The pendulum rotates 135 deg in 3 sec. Then, the angular velocity is : 135/3 = 45 deg/sec.
Hope this helps!

Answer:
the answer would be 80 :)
Answer:
A' (-3, -2)
B' (-3, -10)
C' (3, -10)
D' (3, -3)
Step-by-step explanation:
When reflecting over the y-axis, the x- coordinates don't change, rather only the position of the y-value is shifted. When moving the y-values, it is good to count how many spaces away the point is from the line , so it can be duplicated when you flip it.
Hope this Helps! :)
150 I believe is the answer
