Answer:
= to because the graph has a y int at 1 and so does your formula given (just make x=0 to find it by plugging that in) and that one has a y int at 1 too
Step-by-step explanation:
Answer:
B. 2x2y(x – 3y)(x + 3y)
Step-by-step explanation:
Answer: x + 30 + 90= 180(sum of angles on a straight line)
x= 180-120
x=60
<span>There are several ways to find the max of min of a quadratic equation.
Max occurs when t = -b/2a
t = -b/2a = -68/(2*-4.9) = 6.93 second
Max altitude = h(6.93) = 68(6.93)-4.9(6.93^2) = 235.92 meters
