Elon sat on the dock with his fishing rod, when suddenly he felt the rod being pulled down! He reeled in his
catch, causing it to ascend at a constant rate of 0.1 meters per second. When it reached the water's
surface after 35 seconds, Elon found it was only an old shoe...
Graph the relationship between the shoe's altitude (in meters relative to the water's surface) and time (in
seconds)

The graph is attached.

Step-by-step explanation:

The exercise says that Elon took 35 seconds to pull the boot up to the surface, how the constant rate is:

To know the meters below the surface that is the boot, we multiply the constant rate by the time Elon took to pull up it:

How the boot is pulling up through the time, the formula must subtract the time from the depth, how is below:

Where:

a = depth.

t = time.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
