Please answer this (photo below)
lozanna [386]

Answer:

Please see attached image for the graph

Step-by-step explanation:

To graph the elevation versus time, we start by plotting the first point at time zero (when the climb begins) when Zane is 20 meters below the edge (-20 meters). This corresponds to the point (0, -20).

One second later (1 in the horizontal axis), Zane has moved up 4 meters, now reaching -16 meters. This is the point (1, -16) on the graph.

One second later at time 2 seconds, he is another 4 meters up which corresponds to the point (2, -12) on the graph.

you can go on like this plotting more points on the graph.

Please see the attached image that illustrates this and shows the appropriate line that represents Zane's position versus time (pictured in red)

Part A name the asymptote for the graphed function
jasenka [17]

Answer:

The horizontal line  y=2  is the asymptote


Step-by-step explanation:

This is an exponential function.

An asymptote is the line a function approaches but never touches.

Here, y=2 is the horizontal line that is asymptote of the function.


<u>Note:</u> <em>Normally, y=0 is the asymptote of a parent exponential function, since this graph is parent function shifted 2 units up, the asymptote becomes y=2</em>

Erica babysits for 4.5 hours and is paid $27. If the people she babysits for have $34 to pay her, how long can they stay out?
Zigmanuir [339]

Answer:

5 2/3 hours  

Step-by-step explanation:

We can use a ratio to solve this problem

hours over money


4.5 hours         x hours

-------------    =  ------------

27 dollars        34 dollars


Using cross products

4.5 * 34 = 27 * x

153 =27x

Divide each side by 27

153/27 = 27x/27

5.666666 hours
