Answer:

The short answer is : x=6.81

Step-by-step explanation:

First thing to do is multiply in\sqrt{2}

<h3>To Until it become :</h3>

5x {} ^{2} =164 * \sqrt {2}

Now we will divided on 5 and calculate the numper to it equal 46.3

Then you will take square root To the two parties

To equal in the end =6.81

The simple formula for the nth term of an arithmetic sequence is an = 5n + 15. What is the explicit formula corresponding to the
Nikitich [7]
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.

It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1

Then, the explicit formula will be;
an = 20 + 5(n-1).

The correct answer is D.

Jazel time to check your progress. So far you have completed 816 miles which is 47% of the trail. Can you find about how many mi
musickatia [10]

Answer:

1,736.17miles

Step-by-step explanation:

Let the total trip be x miles

If 47% of the total trip is 816, then;

47% of x  = 816

0.47x = 816

Divide both sides by 0.47

x = 816/0.47

x = 1,736.17miles

Hence the total miles for the trip is 1,736.17miles

I need help with this within the next /0 mins sum1 plz help
guajiro [1.7K]

Answer: Second option.

Step-by-step explanation:

Given the function f(x), which is:

f(x)=x

And given the function g(x), which is:

g(x)=2

You need to substiute the function g(x)=2  into the function  f(x)=x in order to find (fog)(x).

Therefore, through this procedure, you get this answer:

(fog)(x)=(2)

(fog)(x)=2

You can observe that this matches with the second option.
