Answer:
b
Step-by-step explanation:
The given curve is → x²=y, which is a parabola opening upwards and vertex at (0,0).
When it is reflected in x axis ,the curve becomes→ x²=-y
The graph of two curves are shown.
Now the curve ,x²= -y is scaled vertically by a factor of 1/8.
So, the equation of curve becomes ,→ x²= -y × 1/8
→ x² = -y/8
Plotting the graph of →x² = -y/8
The curve will shrink, as scaling is less than 1.

Answer:
The tip is $17.08
Step-by-step explanation:
20% = 0.2
85.4(0.2) = 17.08
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.
