Answer:
Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x
Step-by-step explanation:
we have

This is a vertical parabola open downward
The vertex is a maximum
Find the vertex
step 1
Factor the leading coefficient -4

step 2
Complete the square

step 3


step 4
Rewrite as perfect squares

the vertex is the point (1,-21)
so
The maximum value of the quadratic equation is (1,-21)
therefore
Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x
P=i/rt
P=1687.5/(0.09*10/12)
P=22500
Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. That means angle 1 = angle 5 as well.
<span>When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6, and so forth. Since we know angle 1 = angle 5, so from that you can see that r and s are parallel</span>
Miles driven per hour is 60 miles per hour
Hours driven per mile is 0.01667 hours per mile
<em><u>Solution:</u></em>
Given that,
On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours
Therefore,
Miles driven = 210 miles

To find: miles driven per hour and the hours driven per mile
<h3><u>Miles driven per hour</u></h3>

<h3><u>Hours driven per mile</u></h3>

Thus both the miles driven per hour and the hours driven per mile are found
