Answer:
B. -1
Step-by-step explanation:
The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (0 -3)/(4 -1) = -3/3 = -1
The average rate of change from x = 1 to x = 4 is -1.

Step-by-step explanation:
Answer: find the solution in the explanation
Step-by-step explanation:
Let's use resolution of forces by resolving into x - component and y- component.
X - component.
Sum of forces = F1 - F3 - F4cos 15
Sum of forces = 0
5 - 5 - 0.97F4 = 0
- 0.97 F4 = 0
F4 = 0
Y - component
Sum of forces = F2 + F4 sin 15
Sum of forces = 0
5 + 0.26F4 = 0
0.26 F4 = -5
F4 = -5/0.26
F4 = -19.23 N
Simulating F4 back into the equation
Sum of forces = F1 - F3 - F4cos 15
- F4cos Ø = 0
- (-19.23) cos Ø = 0
Cos Ø = 0
Ø = 1
Does the angle formed approximate 15 degrees ? NO
