Answer:
43.8 (44 to the nearest degree)
Step-by-step explanation:
sin^-1(9/13) is the formula used.
Answer:
The numerator is the first number in a division problem (dividend). The denominator is the second number in a division problem (divisor).
Answer: d
Step-by-step explanation:
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
![\frac{y_{2} - y_{1}}{x_{2} - x_{1}}](https://tex.z-dn.net/?f=%20%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%20)
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
![\frac{z-c[tex]y-w= \frac{z-x}{y-w} (x-c)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz-c%5Btex%5Dy-w%3D%20%5Cfrac%7Bz-x%7D%7By-w%7D%20%28x-c%29)
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29)
Now we can substitute
m for the slope, and use any points to plug in
![x_{1}](https://tex.z-dn.net/?f=x_%7B1%7D)
and
![y_{1}](https://tex.z-dn.net/?f=y_%7B1%7D)
.
Hope this helps! :^)
Answer:
30.17 cm
Step-by-step explanation:
area of a circular disc=π*r^2
derivative of area=2*π*r
maximum error= derivative * error in radius
i.e . 2*π*r*0.2
