Answer:

2.2 hours

Step-by-step explanation:

The equation to graph is

4.5cos(4pi/25 x)+15

Find amplitude by subtracting min from max and dividing it by two. a=4.5

Find vertical shift k by finding the midline. Either add 4.5 to 10.5 or subtract 4.5 from 19.5. k = 15

The period is given to be 12.5. Use formula 2pi/b = period to find b. b = 4pi/25

Put the equation into graphing calculator and find what x equals when the graph is 17 (for the first time)

Write a real-life word problem that can be solved using the system of inequalities below. Be sure to define the variables. x + 4
rewona [7]

Greg and George bought shoes at a local store. Greg bought one dress shoe and 4 sneakers and spent less than $400.

George bought one dress shoe and 6 sneakers and spent more than $400.

Inequality signs < and > denote less than and greater than respectively.

To solve the above inequalities in order to find x and y prices, a pair of solutions will be the result since linear inequalities with two variables will have a range of solutions

In other words, to find x and y for the inequalities we find a point (x,y) that satisfies the inequality.

Example: if the price of a dress shoe is $80 and the price of a sneaker is $60, it satisfies the system of inequalities for Greg and George since their shoe expenses stay below and above $400 respectively.

We could then say that the point (80,60) is one of the solutions to the inequalities.

We could graph the inequalities in order to find points on the graph that satisfy the inequalities. To graph the inequality we make the equation a linear equation x+4y=400 and plot a straight line in accordance to the inequality. All points above the line satisfy George's inequality and vice versa.
