Answer:
Total pictures = 84+12 = 96
roll of films = 96 / 24 = 4
she used 4 rolls
Our angle teta is:
teta = 3pi/4
since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)
sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.
cos(3pi/4) = -√2/2
tan(3pi/4) = -1
Answer:
Step-by-step explanation:
Slope = (y2 -y1)/(x2-x1)
y2 = 800, y1 = 400, x2= 4, x1= 2
Slope = (800-400)/(4-2)
= 400/2
= 200calories/hr
