The height after t seconds of an object projected upward with an initial velocity of 48 feet per second from a 210-foot tower ca
svetlana [45]

Given:

The height h of an object after t seconds is

h=-16t^2+48t+210

The height of a neighboring 50-foot tall building is modeled by the equation h=50.

The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5.

To find:

The statement which describes the validity of these solutions.

Solution:

We have,

h=-16t^2+48t+210

Here, t is the time in seconds.

For t=-2,

h=-16(2)^2+48(-2)+210

h=-64-96+210

h=50

For t=5,

h=-16(5)^2+48(5)+210

h=-400+240+210

h=50

So, the value of h is 50 at t=-2 and t=5.

We know that time is always positive so it cannot be negative value. It means t=-2 is not possible.

The solution t = 5 is the only valid solution to this system since time cannot be negative.

Therefore, the correct option is C.

HELP PLEASE?! Determine a radical function that starts at the point (-4,2) and goes to the right and decreases. The domain is al
Diano4ka-milaya [45]

Answer:

f(x) = -√(x-4) + 2

Step-by-step explanation:

(a) Start with the basic function: f(x) = √x.

This would be the top half of a horizontal parabola opening to the right (always positive).

(b) The range is y < 2. This includes negative numbers, so the function must be f(x) = -√x.

(c) The function starts at x = -4. We must shift it four units to the left. We do that by adding four units to x. The function must be f(x) = -√(x + 4). The domain is x > -4.  

(d) The function starts at y = 2. We must shift it up two units. We do that by adding two units to y. The function must be f(x) = -√(x+4) + 2. The range is y < 2.

The figure below is the graph of f(x) = -√(x+4) + 2.
