The population of San de Tokyo has been increasing a lot! The rate of change of the population can be represented by 2x, where x is the time in years. a. Sketch a graph of the function and include five left endpoint rectangles of equal width on the interval 2

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
