Answer:

5 pi:

15.7

Step-by-step explanation:

Square  root : 15

So, 15.7 is GREATER than 15.

I really hope I helped!

Since  15.7 is GREATER than 15. so 5 pi greater than the square root of 225.

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

Perfect square are those integers whose square root is an integer.

Let x-a be the closest perfect square less than x,

and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).

Then, we get:

[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]

We know that the value of pie is 3.14

then 5 pi = 5 x 3.14

= 15.7

Now, Square root of 225 which is perfect square;

√225 = 15

Thus, 15.7 is GREATER than 15.

Therefore,  5 pi greater than the square root of 225.

Answer:

The value of x is 15

Step-by-step explanation:

2x + 3(x - 10) = 45

2x + 3x - 30 = 45

5x - 30 = 45

Now, Add 30 both sides we get,

5x - 30 + 30 = 45 + 30

5x = 75

Now, Divide 5 from both sides we get,

5x/5 = 75/5

x = 15

Thus, The value of x is 15

Hence, Option A is correct

Answer:

X = All Real Numbers

Step-by-step explanation:

Distribute: (6)(x) + (6)(−6) + x = (7)(x) + (7)(−7) +13

Multiply: 6x + −36 + x = 7x + −49 + 13

Combine like terms: (6x + x ) + (−36) = (7x) + (−49 + 13)

Simplify: 7x + −36 = 7x + −36

7x − 36 = 7x −36

Subtract 7 from both sides: -36 = -36

Add 36 to both sides: 0 = 0

Answer:

Anything in the form x = pi+k*pi, for any integer k

These are not removable discontinuities.

============================================================

Explanation:

Recall that tan(x) = sin(x)/cos(x).

The discontinuities occur whenever cos(x) is equal to zero.

Solving cos(x) = 0 will yield the locations when we have discontinuities.

This all applies to tan(x), but we want to work with tan(x/2) instead.

Simply replace x with x/2 and solve for x like so

cos(x/2) = 0

x/2 = arccos(0)

x/2 = (pi/2) + 2pi*k or x/2 = (-pi/2) + 2pi*k

x = pi + 4pi*k   or    x = -pi + 4pi*k

Where k is any integer.

If we make a table of some example k values, then we'll find that we could get the following outputs:

and so on. These are the odd multiples of pi.

So we can effectively condense those x equations into the single equation x = pi+k*pi

That equation is the same as x = (k+1)pi

The graph is below. It shows we have jump discontinuities. These are not removable discontinuities (since we're not removing a single point).
