5 0

Answer:

- 3, 9, 25

Step-by-step explanation:

To find the required terms of the sequence substitute n = 2, 5, 9 into the given rule, that is

a_{2} = - 7 + (2 - 1)4  = - 7 + (1 × 4) = - 7 + 4 = - 3

a_{5} = - 7 + (5 - 1)4 = - 7 + (4 × 4) = - 7 + 16 = 9

a_{9} = - 7 + (9 - 1)4 = - 7 + (8 × 4) = - 7 + 32 = 25

If an object is propelled upward from a height of s feet at an initial velocity of v feet per​ second, then its height h after t
Sergio039 [100]

From the given information we can write the equation:

-16t^2 +96t + 4 = 112

-16t^2 + 96t + 4 - 112 = 0

-16t^2 + 96t - 108 = 0

simplify, change the signs, divide by -4

4t^2 - 24t + 27 = 0


You can use the qudratic formula but this will factor to

(2t-3)(2t-9) = 0

Two solutions

t = 3/2

t = 1.5 seconds at 112 ft on the way up

and

t = 9/2

t = 4.5 seconds at 112 ft on the way back down

Graphically, (green line is 112 ft)
