Answer:
- 1, - 3, - 5
Step-by-step explanation:
Substitute n = 1, 2, 3 into the rule, that is
a₁ = - 2(1) + 1 = - 2 + 1 = - 1
a₂ = - 2(2) + 1 = - 4 + 1 = - 3
a₃ = - 2(3) + 1 = - 6 + 1 = - 5
Answer:
a. 1.13 s
b. 30.25 ft
Step-by-step explanation:
Both questions can be answered by putting the equation into vertex form.
h = -16(t^2 -9/4t) +10 . . . . factor the leading coefficient from the t terms
Complete the square by adding the square of half the t coefficient inside parentheses and the opposite of the same amount outside parentheses.
h = -16(t^2 -9/4t +81/64) +10 +81/4
h = -16(t -1.125)^2 + 30.25
This tells us the vertex of the height curve is at (t, h) = (1.125, 30.25), which rounds to ...
- t = 1.13 seconds
- h = 30.25 feet
In 150 inches there are 12.5 ft
