Juan is rappelling down a 495-foot cliff at a rate of 6 feet per second. Which equation would represent the height Juan is above
ss7ja [257]

Answer:

The equation is H = 495 -6t

Step-by-step explanation:

Here, we want to write an equation that will represent the height Juan is above the ground, after t seconds.

The height we want to calculate is H. The initial height is 495 foot;

At the first second, the decrease in height will be 6 * 1, at the second 6 * 2 and thus at t seconds, the decrease in height will be 6 * t = 6t

Ask the height after t seconds will be;

H = 495 - 6t

Where t represents the time in seconds

The absolute value function, f(x) = –|x| – 3, is shown. What is the range of the function?
vlabodo [156]

Answer:

Range = [-3,-∞)

Step-by-step explanation:

Let us see the parent function of

f(x)=-\left | x \right |-3

The parent function is

f(x) =\left | x \right |

f(x)=-\left | x \right |-3

is translated function. The parent function is reflected along x axis and then shifted down by three units.

please see the attached image.

The range of the parent function is All positive real numbers. Where as the range of translated function f(x)=-\left | x \right |-3 is negative real numbers , from -3 and onward

or

Range = [-3,-∞)
