Although not so common now, consider a phone plan that does not have unlimited texting. your base plan costs you $30 a month and each text sent or received is only 12 cents. write an equation to describe the total monthly cost of your bill with x text messages and y cost.
in one month 217,000 messages were sent between two brothers in philadelphia. what was their approximate bill? (this is a true story! )

In the triangle abc< angle c is a right angle. find the value of the trig function indicated. find tan a if a =12, b=5 a. 13/12 b. 12/13 c. 5/12 d.12/5

The square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base

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
