Hello!
This submarine rose 100 feet (+100) and then descended (-100). Usually in an equation this would cancel out and make 0. Therefore, our answer is 0.
I hope this helps!
Answer:
t(d) = d/65
Step-by-step explanation:
To solve for t, divide by its coefficient:
d = 65t
d/65 = 65t/65 . . divide* by 65
d/65 = t . . . . . . . simplify
Then you can write it in function form if you like:
t(d) = d/65
_____
* Of course, the rules of equality say you must divide <em>both sides</em> of the equation by the same number.
Answer:
The found the slope incorrectly
The found x over y instead of y over x
Step-by-step explanation:
We first need to find the slope
m = (y2-y1)/(x2-x1)
= (6-3)/(4 --2)
= 3/6
=1/2
The found the slope incorrectly
The found x over y instead of y over x
Answer:
Alison wins against Kevin by 0.93 s
Step-by-step explanation:
Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration 
, we have the following equation of motion
where s (m) is the total distance, ta = 3 s is the time
Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration 
, we have the following equation of motion:
tk = 4 s is the time
Since we can conclude that 
, so Alison would win.
The time it takes for Alison to cover the entire track
The time it takes for Kevin to cover the entire track
So Alison wins against Kevin by 6.93 - 6 = 0.93 s
