Answer:

It took the cell phone 4.15 seconds to reach the ground

Step-by-step explanation:

The formula is  t=\frac{\sqrt{h}}{4} , where t is the time and h is the height

The height of that the cell phone dropped from it is 275 feet above the ground

∴ h = 275

- Substitute the value of h in the formula to find t

∵ t=\frac{\sqrt{275}}{4}

∴ t=\frac{5}{4}\sqrt{11}

- Change it to decimal

∴ t = 4.15 seconds to the nearest 2 decimal places

It took the cell phone 4.15 seconds to reach the ground

1) Describe the relationship of input and outpunt values for a composite functions.

The composition of the functions f(x) and g(x) is defined as:

(f ° g) (x) = f [g(x) ].

That means that the output of the function g(x) is the input of the function f(x).

2) Is the inverse of a function always a function?

No, the inverse of a function is not always a function.

Remember that a function cannot have two different outputs for one or more input.

The reason is that if the original function has two or more inputs that result in a same output, when you inverse the original function, the outputs of the original are the inputs of the inverse function and the inputs of the original are the outputs of the inverse. That implies that the inverse function would have some inputs related with more than one output, which is the negation of a function.

Answer: they are parallel so there is no solution.

Brayden- y=5x-1 or y-5x= -1

Howard- y=5x+1 or y-5x= 1

Vincent- y=4x+5 or y-4x= 5

In summary, they are all parallel so there is no solution. or

5y - 1 = 5y + 1

(Braydon = Howard)

Answer:

1.25 cm

Step-by-step explanation:

Draw a radius line from the center to one of the top corners.  This forms a right triangle where the hypotenuse is r, the width is 1, and the height is 2−r.  Using Pythagorean theorem:

(2−r)² + 1² = r²

4 − 4r + r² + 1 = r²

5 − 4r = 0

r = 5/4

r = 1.25
