Find out what half of 39° (angle ABD) Then subtract that from 180° (angle ABE). When the plain flus faster angle (ABD) gets smaller and angle (ABE) gets bigger. Hope that helps.
ANSWER
The graph in option D.
EXPLANATION
The given function is:

We complete the square to obtain:




The graph of this function opens upwards and has its vertex at (2,-2).
The y-intercept is 10.
From the options the graph that satisfies all these properties is D.
Y = -3x + 2 represents a proportional relationship.

It should be c C: -125p^12 z^18 u^3 if its wrong sowwy
Answer:
1800 J
Step-by-step explanation:
At point A when the cart is not in motion, it only has potential energy.
We know that potential energy is given by mgh where m is the mass of the cart, g is acceleration due to gravity and h is the height.
Substituting 12 kg for m, 10 m/s2 for g and 15 m for h then
PE= 12*10*15=1800 J
