He needs 13 cans of paint.
The lateral area is given by the area of 5 rectangles, whose dimensions are 15 by 5:
5(15)(5) = 375
Divide this by 30:
375/30 = 12.5 ≈ 13
The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.
Hope this helps :)
Answer:
y = 4/5x
Step-by-step explanation:
Two points on the graph is (-5, -4) and (0, 0)
Slope formula is [ y2-y1/x2-x1 ]
0-(-4)/0-(-5)
4/5
The y-intercept is non existent since its 0.
y = 4/5x
Best of Luck!
