Step-by-step explanation:

A ball is thrown straight up from a rooftop 320 feet high. The formula below describes the ball's height above the ground, h, in feet, t seconds after it was thrown. The ball misses the rooftop on its way down and eventually strikes the ground. How long will it take for the ball to hit the ground? Use this information to provide tick marks with appropriate numbers along the horizontal axis in the figure shown.

h=-16t^2+16t+320

lyudmila [28]
The equation can still be solved but it should be stated clearly at what value of would the equation be undefined. For instance, you have an expression,

1/x+2

When x is equal to -2, the denominator will be 0 resulting to an undefined solution. The value of x here can be any real number except -2.

Terry is skiing down a steep hill. Terry's elevation, E(t), in feet after t seconds is given by E(t)=2600−50t.
lesya692 [45]

Answer:

Part 1) The equation tells us that Terry started at an elevation of 2,600 ft

Part 2) The elevation is decreasing by 50 feet each second

Step-by-step explanation:

we have

E(t)=2,600-50t

where

E(t) is Terry's elevation in feet

t is the time in seconds

Part 1) Find the E intercept of the equation

The E-intercept is the value of E when the value of t is equal to zero

so

For t=0

substitute

E(0)=2,600-50(0)

E(0)=2,600\ ft

therefore

The equation tells us that Terry started at an elevation of 2,600 ft

Part 2) Find the slope of the equation

we have

E(t)=2,600-50t

This is the equation of the line into slope intercept form

The slope m is equal to

m=-50\ ft/sec

The slope is negative, because is decreasing

therefore

The elevation is decreasing by 50 feet each second
