Mr. mole left his burrow that lies 7 meters below the ground and started digging his way deeper into the ground, descending at a constant rate. after 6 minutes, he was 16 meters below the ground. let a represent mr. mole's altitude (in meters) relative to the ground after ttt minutes.

Step-by-step explanation:

We are given that

Mr. mole left his burrow that lies 7 meter below the ground .

Therefore, the coordinates of the point (0,-7).

Because initially t=0 and y=-7

After 6 minutes ,

He was 16 meters below the ground.

Therefore, the coordinates of the point (6,-16).

When A represent Mr. Mole's altitude (in m) relative to the ground after t  minutes.

Then, we hate to find the function A(t).

When he started digging his way deeper into ground , at a constant rate.

Then, the rate of change=

Rate of change=-1.5 m/s

The negative sign shows that rate of change decreases.

Therefore, the function

Substitute the values

Then, the function

Here, negative shows that the altitude decreases with time.

in 4 days he will run   12/14

step-by-step explanation:

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
