So 10/360
360 degrees in a circle
so if each spoke turn is 10/360, that means that each turn is 10 degrees out of 360 degrees=10 degrees
answer is 10 degrees
Answer:
The area of the rectangle is 42 units^2
Step-by-step explanation:
we know that
The area of rectangle is equal to
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
In this problem
AB=DC
BC=AD
see the attached figure with letters to better understand the problem
we have that
![L=BC\\W=AB](https://tex.z-dn.net/?f=L%3DBC%5C%5CW%3DAB)
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have the points
![A(2,-1),B(5,2),C(12,-5),D(9,-8)](https://tex.z-dn.net/?f=A%282%2C-1%29%2CB%285%2C2%29%2CC%2812%2C-5%29%2CD%289%2C-8%29)
<em>Find out the distance BC</em>
we have
![B(5,2),C(12,-5)](https://tex.z-dn.net/?f=B%285%2C2%29%2CC%2812%2C-5%29)
substitute in the formula

![d_A_B=\sqrt{18}\ units](https://tex.z-dn.net/?f=d_A_B%3D%5Csqrt%7B18%7D%5C%20units)
<em>Find out the area</em>
![A=(L)(W)](https://tex.z-dn.net/?f=A%3D%28L%29%28W%29)
we have

Answer:
195 = 3 mph
Step-by-step explanation:
This is probly wrong but I tried
Explanation:
We need to find two points that are solutions to the equation.
So, if x = 0, then:
y = -3x - 4
y = -3(0) - 4
y = 0 - 4
y = -4
And, if x = 1, then:
y = -3(1) - 4
y = -3 - 4
y = -7
Answer:
Then, the line passes through the points (0, -4) and (1, -7). So the graph of the equation is:
Answer:
A
