The correct answers are:1) sin(x) =
2) tan(x) =
Explanation:Given:
Step 1:
Since, according to the Trigonometric identity:
-- (1)
Step 2:
Plug in the value of cos(x) in equation (1):
Step 3:
Take square-root on both sides:
sin(x) =
Now to find the tan(x), we would use the following formula:
tan(x) =
--- (2)
Plug in the values of sin(x) and cos(x) in equation (2):
tan(x) =
Hence tan(x) =
Answer:
Only one.
Step-by-step explanation:
Given that there are 25 cookie of the same type in a cookie jar.
We have to select 4 cookies from these 25.
Since they are all the same type, they are identical.
The question is
How many ways can you choose 4 cookies from a cookie jar containing 25 cookies of all the same type?
There is no difference if we take any four cookies from these 25.
Hence no of different ways = 1
Only one is the answer.
Answer:
Domain of y=![\sqrt[4]{x-1}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx-1%7D)
: is x>=1
Interval notation: [1,∞)
Step-by-step explanation:
We have y=
1) The domain of a function is the set of x values for which the function is real and defined.
2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.
3) Now we solve the inequality x-1>=0
4) Adding 1 to both sides of the inequality we get,
x-1+1 > = 0+1
5) Cancel out -1 and +1 from the left side
6) We get x>=1
It concludes that for the domain of the given function, the x value must be greater than or equal to 1
Answer:
9) Vincent will not get the correct answer because the + 484 is unneccesary, as he already subtracted it.
10a) 310,000 + x = 465,000; so x = 155,000
10b) 930,000/310,000 = 3 times more

Answer: 200 feet longer
Step-by-step explanation:
8,556 rounded to the nearest hundred is 8,600
8,371 rounded to the nearest hundred is 8,400
8,600-8,400=200
