Answer:
y= 1/4x+5
Step-by-step explanation:
y=mx+c
to calculate gradient: change in y/change in x
-3/-12 = 0.25
y = 1/4x+c
4 * 1/4 = 1
6-1 = 5
c= 5
Totally:
y= 1/4x+5
A: for every foot you will divide by 9 feet.
B: divide 15 by 9
The trigonometric function's formula, which simulates the torque (tau) that the weight applied t minutes after Thomas attached it is
![3 Sin (\frac{2\frac{22}{7} }{60} (t-51))](https://tex.z-dn.net/?f=3%20Sin%20%28%5Cfrac%7B2%5Cfrac%7B22%7D%7B7%7D%20%7D%7B60%7D%20%28t-51%29%29)
The angular speed of the minutes hand is
rad/min
Following the application of weight, the torque as a function of time t is,
![t= t_{0} sin (w (t-5) min)\\ = (3 Nm) sin ((\frac{2 (\frac{22}{7} }{60} ) rad/min (t-5) min)](https://tex.z-dn.net/?f=t%3D%20t_%7B0%7D%20sin%20%28w%20%28t-5%29%20min%29%5C%5C%20%3D%20%283%20Nm%29%20sin%20%28%28%5Cfrac%7B2%20%28%5Cfrac%7B22%7D%7B7%7D%20%7D%7B60%7D%20%29%20rad%2Fmin%20%28t-5%29%20min%29)

What is torque ?</h3>
Torque, which is also known as the moment of a force, is the propensity of a force to rotate the body to which it is applied. Force (F) x Distance (r) = Torque is how torque is calculated. The distance (r) between the pivot point and the force's action point. A vector quantity is a torque. As a vector quantity, torque always has a direction that is perpendicular to the plane that contains the vectors of force and displacement.

Answer:
my answer was 7.5
Step-by-step explanation:
2
2b+3b-10
4b+3b-10
10-7b=3b fraction bar means divide so...
3b
__ 2
4b because... b-2b=4b and 8-4b=4b
3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)
