Answer:
Step-by-step explanation:
a)
y=−1/12x^2+6x+3
y=−1/12(0)^2+6(0)+3
y = 3
b)
y=−1/12x^2+6x+3
y = -1/12 (x^2-72x) + 3
y = =-1/12 (x^2-72x+1296-1296) +3
y = -1/12(x^2 -72x +1296) + 108 + 3
y = -1/12 (x - 36)^2 +111
maximum height of the ball is 111 feets
c)
y = -1/12 (x - 36)^2 +111
0 = -1/12 (x - 36)^2 +111
-111 = -1/12 (x - 36)^2
1332 = (x - 36)^2
36.497 = x - 36
x = 72.497
How far from the child does the ball strike the ground = 72.497 feets
One would have to believe since there is only 3 angles, it is a triangle which has a total of 180 degrees. They give us the degrees for all the angles, we just have to add them up and solve for x.
180° = ∠A + ∠B + ∠C
180° = 65° + (3X-10)° + 2X° Drop the parentheses
180° = 65 + 3x - 10 + 2x Combine like terms
180° = 55 + 5x subtract 55 from both sides
125° = 5x divide both sides by 5
25° = x substitute this value for x into the ∠'s
∠A = 65°
∠B = 3x - 10
= 3(25) - 10
= 65°
∠C = 2x
= 2(25)
= 50°
( a ) angle 6 and angle 7
( b ) angle 2 and angle 4
( c ) angle 1 and angle 5
i have done this lesson a few days ago so i know that this is right :) if it isnt im so sorry but i have tried my best
hope this helps!! pls also mark me brainliest if you can :)) i am trying to level up. thank you!!
Answer:
Ok
Step-by-step explanation:
Also can i get a brainliest to level up please
Answer:
The answer is 48
Step-by-step explanation:
Just take one of the points shown in the graph and in this case x is the seconds the plane has being flying up and the y values is how much the plane is climbing. So, divide your x and y values to get your slope so its 192/4 and simplified is 48/1 or 48 per second
