Answer:
The answer is "99.82% and 86.99%".
Step-by-step explanation:
In point a:
In point b:
Answer:
x = 2
Step-by-step explanation:
Taking antilogs, you have ...
2³ × 8 = (4x)²
64 = 16x²
x = √(64/16) = √4
x = 2 . . . . . . . . (the negative square root is not a solution)
___
You can also work more directly with the logs, if you like.
3·ln(2) +ln(2³) = 2ln(2²x) . . . . . . . . . . . write 4 and 8 as powers of 2
3·ln(2) +3·ln(2) = 2(2·ln(2) +ln(x)) . . . . use rules of logs to move exponents
6·ln(2) = 4·ln(2) +2·ln(x) . . . . . . . . . . . . simplify
2·ln(2) = 2·ln(x) . . . . . . . . . . . subtract 4ln(2)
ln(2) = ln(x) . . . . . . . . . . . . . . divide by 2
2 = x . . . . . . . . . . . . . . . . . . . take the antilogs
Value of y= 18 and value of x= 9 root3
therefore answer is D
The volume of the sphere is 1437.33 ft³
<h3>
</h3><h3>What is volume of sphere?</h3>
A sphere's volume V is four-thirds of pi times the radius cubed. A hemisphere's volume is half of the volume of the associated sphere.
The volume of a spherical.
V= 4/3 πr³
radius= 7ft
So,
V= 4/3*22/7*7*7*7
V= 30184/21
V = 1437.33 ft³
