A≈1452.2
A=\pi r^2
R=21.5 because 43/2 is 21.5 so plug and chug
Answer:
2e+15
Step-by-step explanation:
Answer:
13. b. 4 + 5x = 29; $5.
14. c. 74 + w = 3w + 6; 34 pounds.
15. b. $42.5.
Step-by-step explanation:
13. 4 + 5x = 29
5x = 29-4 = 25
x = 5.
14. 74 + w = 3w + 6
68 = 2w
w = 34.
15. Let x be the money he got last year. Then:
2x + 5 = 90
2x = 85
x = $42.5.
log (m + n) = log m+ log n and proved it m =n/n-1
Given;
If log (m + n) = log m+ log n
To show that the m =n/n-1
Now, According to the question:
We know that,
Log (m + n) = log m + log n
Log (m + n ) = log (mn). [log a + log b = log ab ]
Cancelling the log on both sides.
then,
m + n = mn
=> n = mn - m
=> n = m (n - 1)
=> m = n / n - 1
Hence Proved
log (m + n) = log m+ log n and proved it m =n/n-1
What is Logarithm?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
