Aperson walking across a bridge accidentally drops an orange into the river below from a height of 40 ft. the function h= -16t^2+40 gives the orange'a approximate height h above the water, in feet, after t seconds. graph the function. in how many seconds will the orange hit the water?

1.58113883 seconds

Step-by-step explanation:

h= -16t^2+40

We want to find when h = 0, or when the orange hits the water

0 = -16t^2+40

Subtract 40 from each side

-40 = -16t^2+40-40

-40 = -16t^2

Divide by -16

-40/-16 = -16/-16 t^2

2.5 = t^2

Take the square root of each side

±sqrt(2.5) = sqrt(t^2)

±1.58113883 = t

Now time can only be positive (it can't hit the water before it is dropped),

so t= 1.58113883 seconds

(3x-8) or (3x+8)

step-by-step explanation:

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
