Answer: t = 6 s

Step-by-step explanation:

When Rose hit the water, the height of the jump is 0, so: h(t) = 0.

Resolving it, we have:

-16t² + 16t + 480 = 0

To simplify the second degree equation, divided it by 16:

-t² + t + 30 = 0

Now, solve the equation using Bhaskara:

Δ = 1² - 4. (-1) . 30

Δ = 1 + 120

Δ = 121

t = \frac{-1+\sqrt{121} }{-2}

t₁ = \frac{-1 + 11}{-2} = - 5

t₂ = \frac{-11-11}{-2} = 6

Since time can be negative, it took t = 6s for Rose to hit the water.

Find three consecutive integers such that twice the smallest is 12 more than the largest.
iris [78.8K]

Answer:

14, 15, 16

Step-by-step explanation:

Let integers equal:

x, x + 1, x + 2

2x = 12 + (x + 2)

2x = 12 + x + 2

2x = 14 + x

2x - x = 14

x = 14

x = 14

x + 1 = 14 + 1 = 15

x + 2 = 14 + 2 = 16
