You removed a rectangular concrete pad from your backyard and are now trying to sod it. You lay down 20 pieces of sod where each one was 2.5 square feet. What is the area of the area you are resoding?
A) 20 square feet
B) 50 square feet
C) 125 square feet
D) 1000 square feet

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

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

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
