Answer:

[tex]I=\frac{x^3}{3(25x^2+1)^{3/2}}[/tex]

Step-by-step explanation:

(a)

[tex]5x=tan{\theta}\\x = \frac{\tan{\theta}}{5}\\dx=\frac{1}{5}\sec^2{\theta}d\theta\\[/tex]

[tex]I=\frac{1}{125}\int\frac{tan^2{\theta}sec^2{\theta}}{(tan^2{\theta}+1)^{5/2}}d\theta[/tex]

[tex]I=\frac{1}{125}\int\frac{tan^2{\theta}sec^2{\theta}}{sec^5{\theta}}d\theta[/tex]

[tex]I=\frac{1}{125}\int\frac{tan^2{\theta}}{sec^3{\theta}}d\theta[/tex]

[tex]I=\frac{1}{125}\int\sin^2{\theta}{cos{\theta}}d\theta[/tex]

[tex]I=\frac{1}{125}\int\sin^2{\theta}d\sin{\theta}[/tex]

[tex]I=\frac{1}{125}\frac{1}{3}sin^3{\theta}}[/tex]

[tex]I=\frac{1}{125}\frac{1}{3}(\frac{5x}{\sqrt{25x^2+1})})^3[/tex]

Answer : 46,47,48,49,50,51,52,53, and lastly 54

Explanation : You have to pick a number between 46 - 53 since the number can't be GREATER than 55 for example the answer can't be 60, because it is TOO great a number. However it can't greater than 45, so it can't 35 because it is TOO less of a number, so 46 - 53 are the only options. I hope this helped.

Answer:

Step-by-step explanation:

Answer:

6 (10 + 7) = (6 x 10) + (6 x 7)

Step-by-step explanation:

Assuming the answer choices are like this:

Distributive Property is the act of taking one number or variable and multiplying it into a set interval. We always distribute before anything else in the equation (PEMDAS) For example:

4 (3 - 5)

The act of distribution is multiplying the 4 by all variables inside the following parenthesis. This act would make the equation turn into this:

4 (3 - 5) → (4 x 3) - (4 x 5) → (12 - 20) → -6

This means out of the option choices the only feasible answer would be:

6 (10 + 7) = (6 x 10) + (6 x 7)

Step-by-step explanation:

3/5 is just a simplified version of 6/10

3 x 2 is 6

5 x 2 is 10

6/10

and

12/20

Answer:

5.1

Step-by-step explanation:

The tenth's place is the first digit after the decimal. For rounding if the number behind your specific place is greater than or equal to 5, you round it up one number, if it is below 5 the number stays the same.

Example:

If I want to round 6.68 to the tenth's place since the 8 is greater than five, my 6 goes up one number and we get rid of the other numbers. Therefore it would be 6.7

If I want to round 6.64 to the tenth's place since the number is not greater than or equal to five, the number stays the same and we get rid of the others. Therefore it would be 6.6

In your case of 5.1249, we only look at the number after the tenth's place to check if it is greater than or equal to five, which it is not, which is why we do not round up, giving us 5.1.

Answer:

a number is increased by 5%

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

Explanation:

Refer to the figure below.

The cone has a circle at the base which has a diameter of 8 cm. This cuts in half to 4 cm, and that's the radius. This forms the horizontal leg of the right triangle highlighted in red.

The vertical leg of the triangle is the height of the cone (9 cm).

---------

Use the pythagorean theorem to find the hypotenuse of the triangle, which is exactly the slant height.

a^2 + b^2 = c^2

4^2 + 9^2 = c^2

16 + 81 = c^2

97 = c^2

c^2 = 97

c = sqrt(97)

c = 9.84886

When rounding to one decimal place, we get 9.8 cm which is the final answer.

Answer:

I realise you've probably gotten past this question, but I'm throwing it out for all future askers of this question ¯\_(ツ)_/¯

C) ƒ(x) increases by a factor of 3

ƒ(x) increases by a factor of 3

f(4) = 3^4

f(5) = 3^5

f(5) /f(4)  =  3^5 /3^4  = 3^5−4 = 3^1 = 3

The value of ƒ(x) changes from 81 to 243 over the interval from x = 4 to x = 5.

This is an increase by a factor of 3.

Step-by-step explanation:

Answer:

9.4

Step-by-step explanation:

Average = Sum of all values/ Total number of value

= 9 + 12 + 7 + 11 + 8/ 5    (as there are 5 numbers, which are 9, 12, 7, 11 and 8)

= 47/5 = 9.4

So the average is 9.4

Answer:

So you need to find the surface area...

Step-by-step explanation:

The length is 20, the width is 14, and the height is 10. It is a rectangular prism so it has six sides.

Two of the sides are l*w

Two of the sides are w*h

and two of the sides are l*h

This gives us equations of 2*(20*14), 2*(14*10), and 2*(20*10)

simplify that to 2*280, 2*140, and 2*200. Then you simplify that to,

560,280,and 400. Now simply add these numbers together to get.

1240.

So your answer is...
