For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet
Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.
The answer to this question is:
False. 84859 is less than 84949
Let's actually find the line of best fit...
m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)
m=(11*836-130*55)/(11*385-3025)
m=2046/1210
m=93/55
b=(Σy-93Σx/55)/n
b=(55Σy-93Σx)/(55n)
b=(7150-5115)/(55*11)
b=185/55, so the line of best fit is:
y=(93x+185)/55
A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.
Which means that those who do not practice at all will win about 3.36 times
B) y(13)=(93x+185)/55
y(13)≈25.34
So after 13 months of practice one would expect to win about 25.34 times.
let x=k
D=dog
T=Taxes
I=increase P=population
solve k
d=23,000
t=2000
d=2.3e^
divide both sides by 2
after year is,2000+k2-2.3
=1.999.7
k2- 23,000=
k-x
or
k2-2
1% is the answer because you have to bump it up two place and it is always the first number.
