I can try to help you, but im just not a good explainer to be honest
General formula to determine the equation of the liney - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slopeGiven:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =
Plug in the numbers
m =
m =
m =
m = 7
The slope is 7
Determine the line equationPlug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
We want to know when h is equal to 0. This represents when the height is 0 and thus, hits the ground.
Then, 0 = 70t - 5t²
0 = 5t² - 70t
0 = 5t(t - 14)
t = 0 and 14.
So, at t = 0, the initial height is 0 and it hits the ground again after 14 seconds.
Answer:
171 degrees
Step-by-step explanation:
If angle POS is 39 degrees, then the measure of arc PS is 39 degrees
You can apply this to arc SQ and QR
So:
39+90+42= measure of arc RPQ
171 degrees= measure of arc RPQ
