1) WET SURPRISE A water balloon is launched off of a patio. The path of the water

mart [117]

The function of the water balloon is an illustration of a quadratic function.

The balloon will splat on the ground after 2.5 seconds

The function is given as:

$h(t) = -6t^2 + 13t + 5$

When the balloon splats on the ground, the value of h(t) is 0.

So, we have:

$-6t^2 + 13t + 5 = 0$

Expand the expression

$-6t^2 + 15t- 2t + 5 = 0$

Factorize the above expression

$-3t(2t - 5)- 1(2t - 5 )= 0$

Factor out 2t - 5 in the 2t - 5

$(-3t - 1)(2t - 5 )= 0$

Split the equation into 2

$-3t - 1 = 0\ or\ 2t - 5= 0$

Rewrite as:

$-3t = 1\ or\ 2t = 5$

Solve for t

$t = -\frac 13\ or\ t = \frac 52$

The value of t cannot be less than 0 i.e. negative.

So, we have

$t = \frac 52$

Divide 5 by 2

$t = 2.5$

Hence, the balloon will splat on the ground after 2.5 seconds

Randy and Carla like to walk the path

Maksim231197 [3]

<h3>Answer: 18 miles</h3>

Reason:

The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.

Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.

The difference of those results is 44-26 = 18 miles.

If you wanted to do the full calculation in one line, then it would be

2*22 - 2*13 = 18

or you could say

2*(22-13) = 18

Answer:

V =1884 in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi ( 10) ^2 * 6

V = pi ( 600) in^3

Using 3.14 for pi

V = 3.14 * 600 in ^3

V =1884 in ^3
