Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Answer:

Answer:
y = - 1
Step-by-step explanation:
Given
2y - 3(4y - 3) = 9y + 28 ← distribute and simplify left side
2y - 12y + 9 = 9y + 28
- 10y + 9 = 9y + 28 ( subtract 9y from both sides )
- 19y + 9 = 28 ( subtract 9 from both sides )
- 19y = 19 ( divide both sides by - 19 )
y = - 1
Answer:
0.5052 cm per sec ( approx )
Step-by-step explanation:
∵ The volume of a cone is,

Where,
r = radius,
h = height,
Here, r = 2 and h = 8,
Thus, the volume of the cone is,

When the cone is half filled,
Volume would be,

Now, 



Differentiating equation (1) with respect to t ( time )

We have,
