Answer:
B.
- as x increases, f(x) decreases;
- as x decreases,f(x) decreases
Step-by-step explanation:
The function is of even degree with a negative leading coefficient. f(x) will tend toward negative infinity as x gets larger or smaller. That is ...
- as x increases, f(x) decreases;
- as x decreases,f(x) decreases
_____
<em>Even degree</em> means the end behaviors are the same for both large and small x. <em>Negative leading coefficient</em> means the function value decreases for larger x.

Answer:
Step-by-step explanation:
Since this is not a right triangle, we will use the Law of Sines. For us that looks like this:
and cross multiply to get
4sin55 = 3.5sinx and solve for sinx:
so
sinx = .9361737 Use the 2nd button on your calculator and the sin button to find that the angle
x = 69.4°. Not sure how you need it rounded. It's actually 69.4186°
Answer:
weight of 25 students
25 × 58 = 1450kg
weight of 29 students
29 × 62 = 1798kg
total students = 25 + 29 = 54
total weight of students = 1450 + 1798 = 3248
mean weight of all students = 3248/54 = 60.19kg
