Answer:
3x^11+9x^7+5x^3-x+4
Step-by-step explanation:
A polynomial written in decreasing order is a polynomial that starts with terms with the highest degree and ends with terms to the lowest degree.
First find the decreasing order of the answer:
5x^3-x+9x^7+4+3x^11
3x^11+9x^7+5x^3-x+4
The answer should be this, but I couldn't find a match for it in the answer box.
Filling in 16 for <em>a</em>, we have ...
... lower limit ≤ heart rate ≤ upper limit . . . . . . . this is the meaning of upper and lower limits
... 0.5×(220 -16) ≤ heart rate ≤ 0.9×(220 -16) . . . . . substitute given expressions
... 0.5×204 ≤ heart rate ≤ 0.9×204 . . . . . . . . . . . . . begin expression evaluation
... 102 ≤ heart rate ≤ 183.6

Answer:
Mark and Lila are 29.83 meters apart.
Step-by-step explanation:
If we draw a triangle with the information given (see image attached), we have that the angle Lila-Avery-Mark is equal to 70°. Then, to find the distance between Mark and Lila, we just need to use the law of cosines, using the two sides given and the angle between them:
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 30^2 + 20^2 - 2*30*20*cos(70)
c^2 = 900 + 400 - 1200*0.342
c^2 = 889.6
c = 29.83 m
Mark and Lila are 29.83 meters apart.
