Answer:
h = 30°
Step-by-step explanation:
All angles in a triangle add up to 180°, so:
60° + 90° + h° = 180°
Solving for <em>h</em>, we should get 30 as our answer.
Answer:
83.241
Step-by-step explanation:
To divide by 10, move the decimal point one place left.
832.41 ÷ 10 = 83.241
Answer:
10a
Step-by-step explanation:
First, write down y=a(x-the x coordinate of the vertex)^2+the y coordinate of the vertex)
second, plug the x coordinate and coordinate of the given point in the above equation to find out a
For example, vertex is (1,2), the point is (3,4)
y=a(x-1)^2+2
then plug in x=3, y=4 in the above equation to find out a
4=a(3-1)^2+2
4=4a+2
4a=2
a=1/2
the equation of the parabola with a vertex at (1,2) and passes through the point (3,4) is 0.5(x-1)^2+2
