Answer:
C is correct.
Step-by-step explanation:
y>= x -2 is easy to see but x + 2y <4 is easier to see if rewritten in slope-intercept form:
y< -1/2x +2
Answer:
192 cm
Step-by-step explanation:
3.5+4.5=8
8*24=192
Answer:
Here you go let me know if you need anything else
Step-by-step explanation:
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
