Answer:
36 feet
Step-by-step explanation:
The given equation is:
To find the maximum height, we complete the square to write the function in the vertex form:
This equation is of the form:
where k=36 is the maximum height reached by the projectile.
-7x + 4y = -6
2x - 5y= 21
<u>Make it so x's are equal</u>
-14x + 8y = -12
-14x - 40y = 147
<u>Subtract</u>
-32y = -169
<u>Divide</u>
y = 5.28125
<u>Plug in the y value</u>
2x - 5(5.28125) = 21
<u>Simplify</u>
2x -26.40625 = 21
<u>Add</u>
2x = 47.40625
<u>Divide</u>
x = 23.703125
Hope this helps! ;)
now onto the second one,
now, the extraneous part, I don't see either as extraneous, 3 and 12 do work, however, I take it is referring to the root, so if we nevermind the root has ± versions, and say only assuming the value coming from the root is say positive, then
Because you have more friends than oranges, you can assume that each person will only get part (or a fraction of) an orange.
If you divide 5 oranges for 6 people, your equation looks like 5 / 6, so each person gets 5/6th of an orange, or about 0.833 oranges per person.
Hope this helps :)
