Answer:297

Step-by-step explanation:

According to the table the inverse of f(x) does not have an x-intercept

The y-intercept of the point where the x-values are zero. From the table of the function f(x), the function has a y-intercept at the point where x = 0

For the table of its inverse, there is no point where y is zero, hence the inverse of the function has no x-intercept

We can therefore conclude that according to the table the inverse of f(x) does not have an x-intercept

You can check that both series converge for all real x (say, using the ratio test).

Now,

[tex]\displaystyle e^x = \sum_{n=0}^\infty \frac{x^n}{n!} \implies x e^{-x^2/2} = \sum_{n=0}^\infty \frac{(-1)^n x^{2n+1}}{2^n n!}[/tex]

and if you have some familiarity with differential equations, you might recognize that the second series represents a Bessel function, namely

[tex]\displaystyle I_0(x) = \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2}[/tex]

but we won't bother making use of this.

In the integral, we interchange the integral with the sum

[tex]\displaystyle \int_0^\infty x e^{-x^2/2} \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2} \, dx = \sum_{n=0}^\infty \frac1{2^{2n} (n!)^2} \int_0^\infty x^{2n+1} e^{-x^2/2} \, dx[/tex]

and consider the sequence of integrals,

[tex]J_n = \displaystyle \int_0^\infty x^{2n} x e^{-x^2/2} \, dx[/tex]

Integrating by parts with

[tex]u = x^{2n} \implies du = 2n x^{2n-1} \, dx[/tex]

[tex]dv = x e^{-x^2/2} \, dx \implies v = -e^{-x^2/2}[/tex]

Then the contribution of uv is 0, so

[tex]J_n = \displaystyle 2n \int_0^\infty x^{2(n-1)} x e^{-x^2/2} \, dx = 2n J_{n-1}[/tex]

We have

[tex]J_0 = \displaystyle \int_0^\infty x e^{-x^2/2} \, dx = 1[/tex]

so that

[tex]J_n = 2n J_{n-1} = 2n (2(n-1)) J_{n-2} = 2n (2(n-1)) (2(n-2)) J_{n-3}[/tex]

and so on; after k steps,

[tex]J_n = 2n (2(n-1)) (2(n-2)) \cdots (2(n-(k-1))) J_{n-k}[/tex]

so that when n = k,

[tex]J_n = 2n (2(n-1)) (2(n-2)) \cdots 2 J_0 = 2^n n![/tex]

Then the integral we want is

[tex]\displaystyle \int_0^\infty x e^{-x^2/2} \sum_{n=0}^\infty \frac{x^{2n}}{2^{2n} (n!)^2} \, dx = \sum_{n=0}^\infty \frac{2^n n!}{2^{2n} (n!)^2} = \sum_{n=0}^\infty \frac1{2^n n!}[/tex]

and knowing the series expansion for [tex]e^x[/tex], it follows that the integral has a value of [tex]e^{1/2} = \boxed{\sqrt{e}}[/tex]

Answer:

graph has a minimum ( looks like V or faces upward )

vertex is (1, −6)

Step-by-step explanation:

*** got to put ^ when typing exponents!!!

y=(x−1)^2−6

y=x^2-2x+1−6

y=x^2-2x-5

basic form is

y = ax^2+bx+c

x vertex = -b/2a

x vertex = -(-2)/2(1)

x vertex = 2/2

x vertex = 1

y vertex = plug x back into the equation

y vertex = y=(1)^2-2(1)-5

y vertex = y=1-2-5

y vertex = y=-6

vertex is (1, −6)

basic form is

y = ax^2+bx+c

if a is positive curve has a minimum means it looks like V or faces upward

if a is negative curve has a maximum means it looks like ^ or faces down

here a is positive so

graph has a minimum

3. 3,830 r 17

4. 875 r 11

The explanation:

1.

42 x 2 = 84

84 - 11167 = 276 (or "?")

276 - 252 = 247 - 210 = 37

2.

72 x 1 = 72

13714 - 72 = 651 - 648 = 34

3.

24 x 3 = 72

91937 - 72 = 199 - 192 = 73 - 72 = 17

4.

70 x 8 = 560

61261 - 560 - 526 - 490 - 361 - 350 = 11

After divide, solution of the expression are,

42 divided by 11167 = 0.0037

72 divided by 13714 = 0.0052

24 divided by 91937 = 0.00026

70 divided by 61261 = 0.0011

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

42 divided by 11167

72 divided by 13714

24 divided by 91937

70 divided by 61261

Now, We can simplify as;

⇒ 42 ÷ 11167

⇒ 42 / 11167

⇒ 0.0037

⇒ 72 ÷ 13714

⇒ 72 / 13714

⇒ 0.0052

⇒ 24 ÷ 91937

⇒ 24 / 91937

⇒ 0.00026

⇒ 70 ÷ 61261

⇒ 70 / 61261

⇒ 0.0011

Answer:

You are squaring x and -5 on the first equation, and on the second equation you are just squaring x and subtracting 5.

Step-by-step explanation:

And since on the first equation x and -5 are in parenthesis that means that the square goes to both of them.

And the second one there is no parenthesis so the square only goes to the x.

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

Explanation:

A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.

A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.

Since none of the x values repeat themselves in our given set, this means we have a function.

Side note: Any function is a relation, but not the other way around.

Answer:

1, 4, 5, 8 equals to 135 ( you can get these answers by simply calculating: 180 - 45 = 135 ( which are angles in a straight line[8 & 5].) 4 = 135 (corresponding angle to 8) and you get 1 = 135 ( opposite angle of 4)

2, 3, 6 equals to 45 ( you can get these answers from observing. 6 is opposite 45 therefore it is = 45°. 2 = 45( corresponding angle). 3 = 45 (opposite angles of 2 and is also alternate to 6)

Answer:

225 thousand.

Step-by-step explanation:

You are dividing the number in half every time.

Answer:

See Below

Step-by-step explanation:

3,600,000 => 1,800,000 => 900,000 => 450,000 => ?

First, find the pattern.

How would you get from 3,600,000 to 1,800,000?

Lets look at this in a simpler format.

36 => 18

We know that if we divide 36 by 2 we get 18, so divide 3,600,000 by 2.

We get 1,800,000

Now, this might be the pattern. However, before we can say that, we need to test it out with the other #'s. So lets do that.

1,800,000 / 2 = 900,000

900,000 / 2 = 450,000

Great, so we see that this is the pattern: divide by two. Now that we know the pattern, we can continue to find the next number.

450,000 / 2 = ?

450,000 / 2 = 225,000

The next number in the pattern is 225 thousand.

Hope this helps! =D
