Answer:
The location will be at units.
Step-by-step explanation:
A scuba diver descended at a rate of units per second.
Now, if 0 represents the surface of the water and distances below the surface are negative, then after seconds the location of the diver will be given by the followings :
In one second the diver descends by 2.25 units depth.
So, in 12.5 seconds the diver will descend by units i.e.
units depth.
Therefore, the location will be at units. (Answer)
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
, where rise is the vertical value and run is the horizontal value
So we sub in our values:
And simplify:
So now we sub in our new found values into y=mx+c:
y=1/2x+2
