The third option is the best fit for the application of a linear model.

In the first option, there is likely to be a correlation but it cannot be a linear one as goals are missed even from inside the keeper's box.

In the second option, it is safe to assume that each person will at least 2 other so this will follow an exponential model.

In the third option, the stopping distance is given by the equation of motion:
s = ut + 1/2 x at²
And this shows that the distance varies linearly with speed.

7. Two fields at a state park ar

netineya [11]

Answer:

$The$ $map$ $is$ $using$ $a$ $1cm:125 m$ $scale$

Step-by-step explanation:

To figure this out, we must use the scale of the map as a unit.

So we first figure out how many meters are for each centimeter on the map.

" Two fields at a state park are fields are 8 centimeters ap(?)ta state park are 1,000 meters from each other."

<u>Set up the ratio:</u>

$\frac{1000}{8} = \frac{x}{1}$

<u>Cross multiply:</u>

$8x$ = $1000$

<u>Meaning:</u>

$x = \frac{1000}{8}$

1000/8

==> 125

x = 125

Meaning that for every centimeter there is 125 meters

1cm = 125m

If x4 + 4y = 8xy, then dy/dx=

Galina-37 [17]

Step-by-step explanation:

x^4+4y=8xy

=>8xy-4y=x^4

=>4y(2x-1)=x^4

=>4y=x^4/(2x-1)

differentiating both side we got

4 dy/dx={4x^3(2x-1)-2x^4}/(2x-1)^2

i.e, dy/dx=(6x^4-4x^3)/4(2x-1)^2

=(6x^4-4x^3)/(16x^2-16x+4)

e Carlos rented a truck for one day. There was a base fee of $ 20.99 , and there was an additional charge of 88 cents for each m

Sonja [21]

Let Base fee be X and No. of Miles be Y.

According to the question
Total Charge= (X+ 88Y)
251.55=20.99+ 0.88Y
Y= 251.55-20.99/0.88
Y= 262 miles
