What decimal equivalent of 5/6

Simplify the complex number i^39 as much as possible.
Answer:
-i
Step-by-step explanation:
i = [tex]\sqrt{-1}[/tex]
[tex]i^{2}[/tex] = - 1
Every [tex]i^{x}[/tex] will be equal to -1, when n is even.
Break apart [tex]i^{39}[/tex] into ([tex]i^{38}[/tex])([tex]i^{1}[/tex])
Since 38 is even, [tex]i^{38}[/tex] will be equal to -1
-1*([tex]i^{1}[/tex]) = -i
To simplify i^39, we must use the cyclical pattern of i's powers, which repeats every four. i^39 simplifies to i^3, which is equal to -i.
To simplify the complex number i^39, we should recognize the cycle of powers of i. Since i represents the square root of -1, the powers of i cycle every four powers:
i = ii^2 = -1i^3 = -ii^4 = 1To find the equivalent of i^39, we can divide 39 by 4 to get a quotient and a remainder: 39 divided by 4 is 9 with a remainder of 3. This means that i^39 is equivalent to i^3, which is -i.
in order to lose 1 pounds one, must burn off 3500 calories. To burn off 100 calories you must bicycle at 9 mph for 15 minutes. How long do you have to bicycle at 9 mph to lose 7 ponds?
Final answer:
The student needs to bicycle for a total of 61.25 hours at 9 mph to lose 7 pounds.
Explanation:
The subject of the question is Mathematics, and it relates to calculating the amount of exercise needed to achieve a certain weight loss goal. The student wants to know how long they must bicycle at 9 mph to lose 7 pounds.
First, we know that to lose 1 pound, one must burn off 3,500 calories. Since 15 minutes of bicycling at 9 mph burns 100 calories, we calculate the time required to burn 3,500 calories (for 1 pound) and then multiply by 7 for the 7 pounds.
To lose 1 pound:
3,500 (calories per pound) / 100 (calories per 15 minutes) = 35 (15 minute sessions to lose 1 pound).
35 sessions * 15 minutes = 525 minutes.
To lose 7 pounds:
525 minutes (to lose 1 pound) * 7 = 3,675 minutes.
3,675 minutes can be converted into hours by dividing by 60 minutes per hour:
3,675 minutes / 60 = 61.25 hours.
Therefore, the student needs to bicycle for a total of 61.25 hours at 9 mph to lose 7 pounds.

How are the decimals .009 and .09 related?
Answer:
0.09 is ten times of 0.009
Step-by-step explanation:
The two decimals are 0.009 and 0.09
We can rewrite the decimals in the scientific notation.
0.009 = [tex]9\times 10^{-3}[/tex]
And 0.09 = [tex]9\times 10^{-2}[/tex]
Now we divide first decimal 0.09 by 0.009
[tex]\frac{0.09}{0.009}=\frac{9\times 10^{-2} }{9\times 10^{-3} }[/tex]
=[tex]\frac{10^{-2}}{10^{-3}}[/tex]
= [tex]\frac{10^{3} }{10^{2} }=10[/tex]
Therefore, 0.09 is ten times of 0.009

Find 10-3 Write the subtraction fact two ways?
There are two ways to write the subtraction fact 10 - 3:
10 - 3 = 7
7 + 3 = 10
What are these two ways?The first way is to simply subtract the two numbers. The second way is to add the two numbers together to get the original number.
Both ways are correct and can be used in different situations. For example, if you are trying to figure out how many apples are left if you have 10 apples and you eat 3, you would use the first way to subtract the two numbers to get 7 apples.
If you are trying to figure out how many apples you need to buy to have 10 apples if you already have 3 apples, you would use the second way to add the two numbers together to get 7 apples.

"a man drove 10 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place of work. if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?"
Answer:
11.2 miles
Step-by-step explanation:
We can create a triangle from the information given.
We can call the starting point (0,0) in the coordinate system.
10 mi east - 10 miles to the right. then,5 mi north - 5 miles aboveSee the attached picture. The direct distance is labeled as x.
Now we need to find x using pythagorean theorem.
Pythagorean Theorem = leg²+leg²=hypotenuse²
Solving for x:
[tex]10^2+5^2=x^2\\100+25=x^2\\125=x^2\\x=\sqrt{125}\\x=11.18[/tex]
Rounding to nearest tenth, we have 11.2 miles
We have that the distance is mathematically given as
AB=11.2miles
From the question we are told
"a man drove 10 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place of work.if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?"DistanceGenerally the equation for the Pythagoras Theorem is mathematically given as
