Multi-Step The sum of the squares of two consecutive odd numbers is 74. a. Write expressions for two consecutive odd numbers.
b. Write an equation to represent the problem. c. What is the possible solution(s)?
If ∠A = 81°, find csc A, sec A, and cot A to the nearest ten-thousandth. Multi-Step Anita figures that the value of her car, in thousands of dollars,
_4 x
can be approximated by f(x) = 15(5 ) , where x is the number of years
after the car’s manufacture. Evaluate the function for x = 0, 1, and 2 and then sketch the function.
Justify Explain why y > 4 has no solutions but y ≥ 4 does. y<4 y≤4
What does a half-life mean? If a substance’s half-life is 25 hours, how many half-lives are there in 150 hours?
Tennis A tennis instructor has a budget of $2000 to buy new rackets. He will receive 2 free rackets wh_en he places his order. The number of rackets, y, that he
2000
can get is given by y = x + 2, where x is the price per racket.
a. What is the horizontal asymptote of this rational function?
b. What is the vertical asymptote?
c. If the price per racket is $200, how many rackets will he receive?
