Answer:
Step-by-step explanation:
<u>Given function</u>
- d(t) = -16t² -6t +480
- Find t, when d = 424
<u>Solution</u>
- -16t² -6t +480 = 424
- -16t² -6t +480 - 424 = 0
- -16t² -6t + 56 = 0
- 8t² +3 t - 28= 0
- t = (- 3± √3² -4*8*(-28))/16
- t = (-3±√905)/16
- t = 1.693 seconds (positive solution)
Answer:
y - y1 = m(x - x1)
Step-by-step explanation:
The point slope form equation is [ y - y1 = m(x - x1) ]
(x1, y1) is any given point on the line.
m is the slope.
To solve this you would need these things:
- Slope (y2-y1/x2-x1)
- Y-intercept (y = mx + b)
Best of Luck!

Answer:
where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is .
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
where −5 ≤ x ≤ 3.
The correct answer would be 3,019.55 aka A.
