Answer: B. log(25) + log(18)
Step-by-step explanation:
Use the rule for the sum of logs: the log of a product is the sum of the logs, which means log(x) + log(y) = log(xy) if they have the same base.
Answer:
The answer is B
Step-by-step explanation:
q=1/4,
32×1/4=8
8×1/4=2
2×1/4=1/2 etc
Answer:
Option (2) and Option (4)
Step-by-step explanation:
From the picture attached,
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC = 
= 
= 
= 12
Now, Sinθ = 
= 
Cosθ = 
= 
tanθ = 
= 
Therefore, Option (2) and Option (4) are the correct options.
Answer:
Step-by-step explanation:
If the two slopes are equal, the lines are parallel. They can't be parallel, because they don't have the same slope
A^2 + b^2 = c^2
The diagonal is the hypotenuse (c).
36.6^2 + b^2 = 42^2
1339.56 + b^2 = 1764
Subtract 1339.56 from both sides.
b^2 = 425.44
Square root both sides.
b = 20.6 inches
