Answer:

Step-by-step explanation:

Using that triangle in the corner the opposite side and adjacent side is 2 and 5 respectively

square of c = square of b plus square of a

in this case a is our hypotenuse

c square = 2 square plus 5 square

c square = 4 plus 25

c square = 29

c is the root of 29

The height, h, in feet of a ball above the ground is given by h = −16t2 + 64t + 80, where t is the time in seconds. How long doe

Gwar [14]

Answer:

t = 5 seconds

Step-by-step explanation:

It is given that, the height h, in feet of a ball above the ground is given by :

$h=-16t^2+64t+80$

Where t is in seconds

We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,

$-16t^2+64t+80=0\\\\t=\dfrac{-64\pm \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=\dfrac{-64+ \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16},\dfrac{-64-\sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=-1\ s\ \text{and}\ t=5\ s$

Neglecting negative time.

It means ball will take 5 seconds to hit the ground.

On a windy day, a 90 foot rope tightly secures a hot air balloon to a stake in the ground. From the balloon, the angle of depres

Alborosie

Answer:

79 ft

Step-by-step explanation:

Balloon - B, stake - S, point at ground - G

Given:

BS = 90 ft
m∠BSG = 62°
BG = x

Use sine and solve for x:

BG/BS = sin ∠BSG
sin 62° = x / 90
x = 90 sin 62 deg
x = 79 ft (rounded)
