Where are the x-intercepts for f(x) = −4cos(x − pi over 2) from x = 0 to x = 2π?

Answers

recall that to get the x-intercepts, we set the f(x) = y = 0, thus

\bf \stackrel{f(x)}{0}=-4cos\left(x-(\pi )/(2) \right)\implies 0=cos\left(x-(\pi )/(2) \right)\n\n\ncos^(-1)(0)=cos^(-1)\left[ cos\left(x-(\pi )/(2) \right) \right]\implies cos^(-1)(0)=x-\cfrac{\pi }{2}\n\n\nx-\cfrac{\pi }{2}=\begin{cases}(\pi )/(2)\n\n(3\pi )/(2)\end{cases}

\bf -------------------------------\n\nx-\cfrac{\pi }{2}=\cfrac{\pi }{2}\implies x=\cfrac{\pi }{2}+\cfrac{\pi }{2}\implies x=\cfrac{2\pi }{2}\implies \boxed{x=\pi }\n\n-------------------------------\n\nx-\cfrac{\pi }{2}=\cfrac{3\pi }{2}\implies x=\cfrac{3\pi }{2}+\cfrac{\pi }{2}\implies x=\cfrac{4\pi }{2}\implies \boxed{x=2\pi }

How many whole numbers less than 500 can be formed using the digits 1, 2, 4, and 5?

Answers

We do casework by the number of digits in the number.

One-digit numbers: 4 choices for the number.

Two-digit numbers: Four choices for the first digit, four for the second, for a total of 4*4=16 numbers.

Three-digit numbers: Five cannot be the first digit, since if that is the case we will have a number over 500, so we have three choices for the first digit and four for each of the others, for a total of 3*4*4=48 numbers.

This is a total of 4+16+48=68 numbers.

If four times a number plus 3 is 11, what is the number?A. 4
B. 5
C. 16
D. 2

Answers

It is very important to readthe question very minutely before going for solving the problem.
Let us assume the unknown number to be = x
Then
4x + = 11
4x = 11 -3
4x = 8
x = 8/4
   = 2
So we can see from the above deduction that the unknown number is 2. The correct option among all the options given in the question is option "D". I hope the procedure is clear enough for you to understand.
