Answer:
Step-by-step explanation:
We have volume of cone as
and for a cone always r/h = constant
Given that r' = rate of change of radius = -7 inches/sec
(Negative sign because decresing)
V' =- 948 in^3/sec
Radius = 99 inches and volume = 525 inches
Height at this instant =
Let us differentiate the volume equation with respect to t using product rule
Rate of change of height = 0.08514 in/sec
Answer:
2 sin x + √3 = 0
2sinx=-√3
sinx=-√3/2
x=sin-¹(-√3/2)(sin-¹ means inverse of sin)
x=-60
Hello there! 46.62 rounded to the nearest dollar is 47. That's because the tenths digit is greater than 5, so we round up from 6 to 7. The new number is 47. Now, we can multiply by 15% to find the approximate amount of the tip, because that will get us to 15% of the amount. 47 * 15% (0.15) is 7.05. The amount of the tip is approximately $7.05.
