Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2

When the projectile hits the ground then the height becomes 0

h = 88t - 16t ^2

0 = 88t - 16t ^2

GCF is -8t

0 = 8t(11 - 2t)

now set each factor =0 and solve for t

8t=0, t=0

11-2t=0, t=\frac{11}{2}

So it will take 5.5 seconds to hit the ground

Answer:

5.5 seconds.

Step-by-step explanation:

The given function is

h = 88t - 16t ^2

where, h is height (in feet) of projectile after t seconds.

We need to find the time taken by projectile to hit the ground.

At ground level, the height of projectile is 0.

Substitute h=0 in the given function to find the time at which it hit the ground.

0=88t - 16t ^2

0=8t(11 - 2t)

Using zero product property we get

8t=0\Rightarrow t=0

11-2t=0\Rightarrow t=\frac{11}{2}=5.5

It mean projectile hits the ground at x=0 and x=5.5 seconds. We know that x=0 is the initial stage.

Therefore, so time taken by projectile to hit the ground is 5.5 seconds.

What is the answer to this math question
mezya [45]

Answer:

11

Step-by-step explanation:

1.80m + 0.6s = 12.00

[substitute the value of m into the equation]

1.80×(3) + 0.6s = 12

5.4 + 0.6s = 12

[make s the subject of the formula]

0.6s = 12 - 5.4

0.6s = 6.6

[divide both sides of the equation by 0.6]

0.6s / 0.6 = 6.6 / 0.6

s = 11

To prove that 11 is correct

[substitute the value of m and s into the equation]

1.80m + 0.6m = 12.00

1.80×(3) + 0.6×(11) = 12.00

5.4 + 6.6 = 12.00

12.00 = 12.00
