Answer:
Example a) the resulting vector is 54 degrees with a force of 48N (4.8cm)
Example b) the resulting vector is 168 degrees with a force of 38N
Example c) the resulting vector is 129 degrees with a force of 57N
Step-by-step explanation:
i had the same assignment so i used the vector calculator online
Answer =124
4+8+16+32+64=124
I hope this helped! :)
Your answer is A. (0,0)
The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept, which is where the line cuts the y-axis.
In the line y = 4x, the ‘m’ would be 4 and the ‘+ b’ would be 0, which means that the line cuts the y-axis when y = 0.
There are only 2 answer options that have y = 0, A (0, 0) and D (4, 0). To find out which is correct, we can substitute in y = 0 into the equation y = 4x to see what the x-value would be:
y = 4x
0 = 4x
0 = x
Therefore the answer is A.
I hope this helps!
Answer:
The survey option that will give cafeteria the valid result is Survey Questionnaire

Answer:
All sides are 8.0
Step-by-step explanation:
this is because it says that 4 square units= 3mm so if you do 3 x 2 = 6 so you do 8.0 for all of the sides :) hope this helps
