Answer: 2/5
Step-by-step explanation:
line up the points and label them XYX2 and Y2. Then subtract X2 minus X1 below Y2 minus Y1 then you will get the slope. In this case it is 2/5 .
Cosine is co added onto sine. Basically, cosine is the sine function moved over 90degrees or pi/2 (pi/2 on a unit circle is 90 degrees)
Sin(x)=cos(x+90) <--degrees
Sin(x)=cos(x+pi/2) <--radians
The above two equations for converting them is called a cofunction identity. There's many more identities to convert sines, cosines, tangents, cosecantes, secantes, and cotangents between each other. This is taught to you in PreCalculus.
First find the number of girls in her class.
29 student - 21 boys = 8 girls
So, the ratio of girls to boys is:
8 girls:21 boys
Or just:
8:21
answer: 8:21
