Answer:
(a) Lying on both axes-
Point lying on both axes will lie on origin, so its coordinate is (0,0)
(b) Lying on x-axis and with x-coordinates 4
Since the point lies on x-axis so its y-coordinate is 0, so its coordinate is (4,0)
(c) Lying on y-axis and y-coordinates -3
Since the point lies on y-axis so its x-coordinate is 0, so its coordinate is (0,-3)
To find the critical points, first we derivate the function:
dy/dx has roots x = 0 and x = -5/6.
When x < -5/6, we can check that dy/dx is negative. When -5/6 < x < 0, we can check that dy/dx is positive. And, when x > 0, we can check that dy/dx is also positive.
Therefore, y is increasing when x > -5/6 and decrasing when x < -5/6. y has inflection points at x = -5/6 and x = 0
Answer:
3.6 liters
Step-by-step explanation:
So the ceiling an the walls, you are covering 5/6 surfaces.
Front 4.2*2.5= 10.5
Side 4*2.5=10
1 Top 4.2*4= 8.4
All together =28.9 M /8= 3.6 liters of paint would be needed
Composite, as there are multiple factors of 36.
(1,2,3,4,6,9,12,18 and 36)
