the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>

h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters

Answer: 2x
Step-by-step explanation: 18+2(x-7)=4+M. First distribute 2 to (x-7), then you will be left with 18+2x-14=4+M. You can further simplify the left side of the equation by subtracting 14 from 18, now you are left with 2x+4=4+M. Subtract 4 from both sides to solve for M, 2x=M.
Here we know that the initial velocity of the car is given by:

And the final velocity of the car is given by:

It took 3 seconds to attain the final velocity, so we have 
Therefore, the acceleration can be obtained by:


Plugging the values of the initial, final velocity and the time, we get:

So the acceleration of the car is given by:

Now we need to find the direction of the average acceleration of the car:

Here, x and y are the coefficients of the 'x' and 'y' components of the vector:

Therefore, the direction of the average acceleration of the car is
.
