Step-by-step explanation:
(f.g)(x) = (9x²-2x-9)(11x-9)
= 99x³-81x²-22x²+18x -99x +81
= 99x³ -103x²-81x +81
optionB
Answer:
Hank was watching the winter Olympics and was amazed at the distance the ski jumpers were able to travel. By looking at their posture in flight Hank was able to determine how they stayed in the air for so long. How does body posture affect flight in ski jumping?
Bending the knees keeps the body tucked for better distance
Holding the arms away from the body allows for better balance and further distance
Leaning backward and more upright increases the chance to ride a thermal
Leaning forward with the head close to the tips of the skis allows for better aerodynamics
Step-by-step explanation:
WHATS THE ANSWER
A graphing calculator shows the minimum to be located at the vertex of the quadratic, x = -2.5, and the maximum to be located at the right end of the interval.
The absolute maximum value of f(x) is ln(18) ≈ 2.89037.
The absolute minimum value of f(x) is ln(5.75) ≈ 1.74920.
180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
