Acar that travels along the highway to denver at a steady speed. when it begins, it is 300 miles from denver. after 3 hours, it is 180 miles from denver. which function describes the car's distance from denver?

Step-by-step explanation:

This car follows a line, hence its motion can be modeled by the Line equation.

In fact, we already have two points of the line, if we call the time in hours and the traveled distance in miles:

Point 1:

Since we are told the car's initial position is 300 miles in the time 0 h

Point 2:

Since we are told the car's final position is 180 miles after 3h

Let's find the Slope :

 This is the slope of the line

Now, the equation of the line is:

We already know the slope, now we have to find the intersection point with the y-axis () with any of the given points. Let's choose Point 1:

Isolating :

Then, the equation of the line is:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
