Which situation is most likely to show a constant rate of change?
a. the number of customers in a grocery store compared with the day of the week
b. the speed of the wind on a stormy day compared with the time of day
c. the amount of gasoline in a car's tank while driving on a highway at a constant speed compared with time
d. the distance of a student from home during a school day compared with the time of day

- C. The amount of gasoline in a car's tank while driving on a highway at a constant speed compared with time.

Explanation:-

A. The number of customers in a grocery store does not change at a constant rate compared with the day of the week.

B.The speed of the wind on a stormy day does not change at a constant rate compared with the time of day.

C.The amount of gasoline in a car's tank while driving on a highway change at a constant rate at a constant speed compared with time

.[as velocity=rate of change in distance]

D.The distance of a student from home during a school day does not change at a constant rate compared with the time of day.[as distance remains constant compared to time]

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
