An electric filter purifies air at the rate of 35 liters per minute and uses energy at the rate of 0.8 Joules per minute. It also purifies water at the rate of 25
liters per minute and uses energy at the rate of 1.3
Joules per minute.
The filter is expected to purify more than
1000 liters of air and water while using less than 170 Joules of energy.

Let A denote the number of minutes it spends purifying air and W
the number of minutes it spends purifying water.

Write an inequality that represents the condition based on the number of liters of air. Write an inequality that represents the condition based on the number of Joules of energy. d water.

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
