The answer is all real numbers.
Answer:
cos (12+10) = cos (22)
Step-by-step explanation:
Cos 12* cos 10* - sin 12* sin 10*
Appling the trig identity: cos (a + b) = cos a.cos b - sin a.sin b
inputing the values of a and b
cos (12 + 10) = cos 12cos 10 - sin 12sin 10 = cos (22)
Answer:
a. After the first bounce, the ball will be at 85% of 8 ft. After 2 bounces, it'll be at 85% of 85% of 8 feet. After 3 bounces, it'll be at (85% of) (85% of) (85% of 8 feet). You can see where this is going. After n bounces the ball will be at
b. After 8 bounces we can apply the previous formula with n = 8 to get
c. The solution to this point requires using exponential and logarithm equations; a more basic way would be trial and error using the previous 
increasing the value of n until we find a good value. I recommend using a spreadsheet for that; the condition will lead to the following inequality:
Let's first isolate the fraction by dividing by 72.
Now, to get numbers we can plug in a calculator, let's take the natural logarithm of both sides:
. Now the two quantities are known - or easy to get with any calculator, replacing them and solving for n we get:
Now, since n is an integer - you can't have a fraction of a bounce after all, you pick the integer right after that, or n>27.
Step-by-step explanation:
It is given that,
A 2-liter bottle of juice costs $2.80.
It means that 1 liter bottle of juice costs $1.4.
A box containing six 12-liter bottles sells for $3.90.
(6×12)l i.e. 72 liter bottles sells for $3.9
1 liter bottles sells for $0.05416
It is clear that "A box containing six 12-liter bottles sells for $3.90." have higher cost per liter. Its cost is $0.05416 per liter. Hence, the correct option is (D).
