Answer:
Option C
Step-by-step explanation:
To answer this question you must use the parallelogram method shown in the attached image.
To answer this question, use the parallelogram method as shown in the attached image.
-Place the vectors a and b at the same point of origin.
-On the tip of the vector b draws a vector a.
-On the tip of vector a to draw a vector b.
-Draw a vector "f" that goes from the origin to the corner of the parallelogram.
The vector "f" represents the sum of the vector a with the vector b.
The correct option is C
1) expand csc and cotx identity
(1/sinx)-sinx = (cosx/sinx)*(cosx)
2) get common denominator on the left side
(1-sin^2x)/(sinx)= (cos^2x)/sinx
3) using cos^2x+sin^2x=1 you finished
cos^2(x)/sinx= cos^2(x)/sinx

Answer:
No
Step-by-step explanation:
The first 3 boxes are proportional since they have a ratio of 1:3, but 6:21 is not proportional to the others.
Bill moves at 45 feet per minute and Greg 75 per minute and starts with a constant of 20 feet from them.
Let X be the number of minutes
Bill*Minutes +Greg*Minutes +20 = total distnce between
45x + 75x +20 = d
Plug in 2.5 for both values of x
45(2.5) + 75(2.5) + 20 =d
Multiply values by 2.5
112.5 + 165 + 20 = d
add together
Distance = 297.5 feet apart
You olny do the problem in some u need to reduce
