The domain of the notation \(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\) is the set of all real values

The sum notation is given as:

\(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\)

From the above notation, the smallest value of n is 1.

This means that the variable x can take any real value as it value

Hence, the domain of the notation \(s(x) = \sum\limits^{\infty}_{n=1} n^{-x}\) is the set of all real values

Answer:

78.5 cm2

Step-by-step explanation:

The formula for the area of a circle is A = πr^2, where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Since the diameter of the circle is 10, we can find the radius by dividing the diameter by 2:

r = d/2 = 10/2 = 5

Now we can plug in the value of r into the formula:

A = πr^2 = 3.14 x 5^2 = 78.5

Therefore, the area of the circle with a diameter of 10 is approximately 78.5 square units.

The area of the given picture frame is 177.5 cm².

Given,

Length of square = 16 cm

The diameter of the circle cut out = 10 cm

We have to calculate the area of the picture frame.

First, we will find out the area of the square.

The area of the square = a² = 16 × 16 = 256 cm²

Now, we will find out the area of the circle that is being cut out from the square.

Area of the circle = πr² = 3.14 × 5² = 78.5 cm²

Then the area of the picture frame = Area of the square - the area of the circle

                                                    = 256 cm² - 78.5 cm²

                                                    = 177.5 cm²

Therefore, the required area of the square frame is 177.5 cm².

Answer:

Large integer = x + 2

x + 2 + x = 38

Step-by-step explanation:

Large integer = x + 2

x + 2 + x = 38

ex.   2.        4.         6.

       x.       x+2.     x+4

x+2 is the  expression which represents the larger of the two integers and x+x+2=38 is the required equation.

Let's represent the two consecutive even integers as x and x + 2, where x is the smaller integer, and x + 2 is the larger integer.

Since the sum of the two integers is 38, we can set up an equation as follows:

x + (x + 2) = 38

Now, we can solve this equation to find the value of x and then find the larger integer (x + 2).

To find the larger integer, we need to drag the correct expression, which is (x + 2), into the box:

Larger integer: (x + 2)

Hence, larger integer is x+2 and x+x+2=38 is the required equation.

Surface area of top opened rectangular prism:

             l = 6 cm ;  w = 6 cm ;  h = 7 cm

     \(\sf \boxed{ \text{ surface area = 2h(l+w) + lw}}\)

                            = 2*7 *(6 + 6 ) + 6*6

Surface area of right triangular prism:

           In, right triangular prism, the base rectangle is not included.

   Surface area = bh + (S1 + S2)*L

         b is the base of the triangle. b= 6 cm

         h is the altitude of the triangle. h = 4cm

         S1 and S2 are the edges of the triangle.

        S1 = 4 cm ;  S2 = 7 cm

        L is the length of the prism. L = 6 cm

          Surface area = 6*4 + (4 + 7)*6

1/2 + 2/3 + 4 /6

We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.

Note that we do not change 4/6, since it already has a denominator of 6.

==> 3/6 + 4/6 + 4/6

Answer:

Step-by-step explanation:

tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.

James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.

so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.

James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

A unit rate means a rate for one of something.

It is written as a ratio with a denominator of one.

We have,

Tamika:

Rate of eating jellybeans = 12 jelly beans per 4 minutes.

12 beans = 4 minutes

Divide it by 4 into both sides

We get,

3 beans = 1 minute ___(1)

Tamika took 30 minutes to finish snack-size beans.

This means from (1),

3 x 30 jelly beans= 30 minutes

90 jelly beans = 30 minutes

There are 90 jellybeans in snack-size beans.

James:

Rate of eating the jellybeans = 28 jellybeans per 7 minutes

It can be written as:

28 jelly beans = 7 minutes

Multiplying 90/28 on both sides we get,

90 jelly beans = (90/28) x 7 minutes

90 jelly beans = 90/4 minutes = 22.5 minutes

This means James takes 22.5 minutes to finish snack-size jelly beans.

We see that,

The time took for Tamika to finish snack-size jelly beans = 30 minutes

The time took for James to finish snack-size jelly beans = 22.5 minutes

we have,

30 - 22.5 = 7.5

Thus,

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

Answer:

$6655

Step-by-step explanation:

I am assuming it is compound interest

$5,000 x 1.1^3 = $6655

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

this should be the right awnser

Step-by-step explanation:

Answer:

100 minutes (or 1 hour and 40 minutes)

Step-by-step explanation:

to start I subtracted 4,500( how much it can hold) by 1,500 (how much it has already) to get 3,000.  

4500 - 1500 = 3000 (300 + 1500 = 4500)

so the pool would need 3,000 more gallons of water to reach the limit,

then divide 3,000 by 30 to know how many 30 gallows would be needed to reach the limit

3,000 ÷ 30 = 100 (100 x 30 = 3,00 so this is correct)

He would need to add water for 100m to avoid exceeding the limit.

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

1.Well, let's try simplifying 4:18 so we can compare.

If we divide 4:18 by 2, we get 2:9  

We can see that 2:9 =/= 2:12

Thus, the two are not equivalent ratios.

2. 5:20 and 15:60 are equivalent, 5:20 x 3 to both numbers is 15:60

Therefore, It is equivalent.

3. 17 times 4 is 68 and 3 times 4 is 12. 17:3 and 68:12 are equivalent because you can times and divide them into each other

4. He read for 180 minutes.
