Answer with explanation:
The equation, y=3 x,
y=Distance traveled
x =Total time
![\frac{\text{Distance traveled}}{\text{Time}}=\frac{y}{x}=3\\\\ \frac{dy}{dx}={\text{Rate of change}}={\text{Velocity}}=3 {\text{unit of time}]](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BDistance%20traveled%7D%7D%7B%5Ctext%7BTime%7D%7D%3D%5Cfrac%7By%7D%7Bx%7D%3D3%5C%5C%5C%5C%20%5Cfrac%7Bdy%7D%7Bdx%7D%3D%7B%5Ctext%7BRate%20of%20change%7D%7D%3D%7B%5Ctext%7BVelocity%7D%7D%3D3%20%7B%5Ctext%7Bunit%20of%20time%7D%5D)
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit ,and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
First, we will find the common difference
The common difference is ;
19 - 11 = 8
or
11 - 3 = 8
common difference is 8
As the position increase by 1, the result increase by 8
so we will keep on adding 8 to the result
Position Result
4 19
5 27
6 35
7 43
8 51
Hence;
when the position is 8, the result is 51
39 meters in 3 minutes means 13 meters each minute and 26 meters in two minutes. Multiply by 1,000 to convert it into 26000 millimeters.
Answer:
the correct answer is (5x+2)^2
