Answer:
Step-by-step explanation:
sin^2x=1/2
so sinx=1/V2=V2/2
x=pi/4
Answer:
A.10
B.10
C. 10,000
D. 8 hours
Step-by-step explanation:
Firstly, we should know that the numbers are labeled 0-9.
A. 10 digits
B. We already took one digit , but we still have 10 choices left again as numbers can be repeated.
C. For the first number, we have 10C1 choices since we are selecting 1 out of 10 numbers. This is the case for all the 3 renaming numbers. Hence the total number of possible passwords are
(10C1)^4 = 10,000 possible password combinations
D. That is (10,000*3)/60 in minutes = 500 minutes = 500/60 = 8.3333 , approximately 8hrs
Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
Answer:
8/18 & 17/18 is your answer.
Step-by-step explanation:
Find common denominators for both (you cannot simplify). Note that what you do to the denominator, you must do to the numerator. Find multiples of each number:
9: 9, 18
18: 18
The first least common denominator you get is 18. Solve:
(4/9)(2/2) = 8/18
8/18 & 17/18 is your answer.
