Answer:
2πl/3
Step-by-step explanation:
find properties of the trigonometric function:
period 2π/3
The general slope-intercept form equation is:

In this case, m=-2 and with the point (4, 10) we can find the value of b:

We found that b = 18, so:
<u>Answer</u>
8√2
<u>Explanation</u>
Simply: 4√2 + 7√2 - 3√2
Let √2 = x
4√2 + 7√2 - 3√2 = 4x + 7x - 3x
= 11x - 3x
= 8x
Substituting x with √2
4√2 + 7√2 - 3√2 = 8√2
Answer:
105km
Step-by-step explanation:
2.5/15=17.5/x (set up as a proportion)
2.5x=262.5 (cross multiply)
