Answer:

t = 5 seconds h = 128 feet

Step-by-step explanation:

The given equation of the object is :

$h(t)=-16t^2+64t+80$ .....1

When it hits the ground,

h(t) = 0

So,

$-16t^2+64t+80=0\\\\t=-1\ s\ and\ t=5\ s$

The object will hit the ground in 5 seconds.

Now, put t = 1 s in equation (1).

$h(1)=-16(1)^2+64(1)+80\\\\h(t)=128\ ft$

The object is at a height of 128 ft at 1 second.

Answer:

$Area = 34.2cm^2$

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

$a = 8$

$b = 9$

$c= 10$

Required

Determine the area

This is calculated as:

$Area = \sqrt{s(s-a)(s-b)(s-c)$

Where

$s = \frac{1}{2}(a + b + c)$

Substitute values for a, b and c

$s = \frac{1}{2}(8 + 9 + 10)$

$s = \frac{1}{2}(27)$

$s = 13.5$

Substitute values for a, b, c and s in

$Area = \sqrt{s(s-a)(s-b)(s-c)$

$Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)$

$Area = \sqrt{13.5 * 5.5* 4.5* 3.5$

$Area = \sqrt{1169.4375$

$Area = 34.2$ -- Approximated
