Answer:
Step-by-step explanation:
Since AC and AB are opposite equal angles AC=AB
2x-24=x-2
x=22
So BC=x=22
Answer:
y = - 16t² + 55.6t + 6
Step-by-step explanation:
Using y - y₀ = vt - 1/2gt² where g = 32 ft/s², and v the velocity of the football
So y = y₀ + vt - 1/2 × (32 ft/s²)t²
y = y₀ + vt - 16t² where y₀ = 6.5 ft
y = 6 + vt - 16t²
Now, when t = 3.5 s, that is the time the teammate catches the ball after the quarterback throws it, y = 5 ft. Substituting these into the equation, we have
5 = 6.5 + v(3.5 s) - 16(3.5 s)²
5 = 6.5 + 3.5v - 196
collecting like terms, we have
5 - 6.5 + 196 = 3.5v
194.5 = 3.5v
v = 194.5/3.5 = 55.57 ft/s ≅ 55.6 ft/s
So, substituting v into y, our quadratic model is
y = 6 + 55.6t - 16t²
re-arranging, we have
y = - 16t² + 55.6t + 6

Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation: 
A second linear equation is given by the table:
Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:
Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)
