I = the square root of -1, so it would be 7i
Answer:
Step-by-step explanation:
9^8 to 9^10 involves a change (multiplication) of 9^8 by 9^2 (which is 81).
Over the given interval, f(x) increases by 81.
<h3>The area of base is 0.25 square meter</h3>
<em><u>Solution:</u></em>
Given that,
The capacity of a cylindrical fuel tank is 2.5 kl and its height 10 m
To find: area of base
<em><u>The volume of cylinder is given as:</u></em>

The area of base of cylinder is area of circle

Therefore,

From given,
h = 10 m
v = 2.5 kl
1 kilo liter = 1 cubic meter
Therefore,
2.5 kl = 2.5 cubic meter
Substitute height = 10 and volume = 2.5

Thus area of base is 0.25 square meter
The sum of 3.0478 and 4.92 is
, which have 5 significant digits.
<u>Step-by-step explanation:</u>
We have ,
and
. The significant digits of a number are digits that includes all digits except:
- All leading zeros. For example, "013" has two significant figures: 1 and 3;
- Trailing zeros when they are merely placeholders to indicate the scale of the number and ,
- Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.
Here
and with significant digit rules
. Now, Sum of both numbers = 
⇒Sum of both numbers = 
⇒Sum of both numbers = 
∴ The sum of 3.0478 and 4.92 is
, which have 5 significant digits.
