<em><u>Answer</u></em>:
The quadratic equation is : x²+x+1=0
<u><em>Step-by-step explanation:</em></u>
Generally:
let S be the sum of the roots z₁ and z₂
and P be the product of the roots z₁ and z₂
then z₁ and z₂ are the solutions for the equation: x² − Sx + P = 0
Now,
S=-1 and P=1 then the equation is x²+x+1=0.

Answer:
i know its more than 720 not too sure on the exacts tho
Step-by-step explanation:
sorry:(
Step-by-step explanation:
A:
No graph has been shown.
B:
<u>1.</u>
d = 2.5(20)
d = 50 meters.
<u>2.</u>
time distance H distance E
0 45 0
5 50 12.5
15 60 37.5
20 65 50
40 85 100
65 - 50 = 15
15 meters
Look at graph image for the distance represented on the graph.
Y=kx^2 (k being a constant)
72=k (3^2)
k=8
y=8x^2
Subtract 10 from both sides
-0.035d=4-5
Simplify 4-10 to 6
0.035y=-6
Divide both sides by -0.035.
D=-6/0.035
Simplify
Y=171.42
