Which formula gives the x-coordinates of the maximum values for y = cos(x)?
solong [7]

We have been given a function y=\cos(x). We are asked to find the formula which gives the x-coordinates of the maximum values for given function.

We know that cosine function oscillates between -1 and 1 that is minimum value of cosine is -1 and maximum value is 1.

We also know that \cos(0)=1 and after period of cosine is 2\pi. This means after every 2\pi, we will get to 1.

So maximum of cosine is 2\pi n, where n is an integer.

Therefore, our required formula is 2\pi n, where, n=0,\pm 1,\pm 2,\pm3,...

Answer:

  3×5×53

Step-by-step explanation:

You can use divisibility rules to find the small prime factors.

The number ends in 5, so is divisible by 5.

  795/5 = 159

The sum of digits is 1+5+9 = 15; 1+5 = 6, a number divisible by 3, so 3 is a factor.

  159/3 = 53 . . . . . a prime number,* so we're done.

795 = 3×5×53

_____

* If this were not prime, it would be divisible by a prime less than its square root. √53 ≈ 7.3. We know it is not divisible by 2, 3, or 5. We also know the closest multiples of 7 are 49 and 56, so it is not divisible by 7. Hence 53 is prime.

A 20 ft ladder leans against a building and reaches a point 13 ft above the ground. Find, to the nearest degree, the angle that
Snezhnost [94]
Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees


Hope this helps! :)
