what is the square root of 83, 10, 63, and 99?​

Answers

Answer: square root of 10 - 100 3.162

√63  =√32⋅7=√32⋅√7=3√7.

Thus, the square root of 99 lies somewhere between 9.9 and 10. Choosing an estimate in the middle of this range, we know that sqrt(99) is approximately equal to 9.95, with an error of not more than 0.05.

Step-by-step explanation:

Explanation: √83 is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.

What is the vertex of the graph of the function below?
y= x2 - 10x + 21
O A. (5,-4)
B. (3,0)
O C. (5,0)
OD. (3,-4)

Answers

Answer:

Step-by-step explanation:

A. (5,-4)

The vertex of the graph of the function is (5,-4).

The answer is option A.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the vertex of the function y = x² - 10x + 21,

We can use the formula:

x = -b/2a

where a is the coefficient of the x² term, b is the coefficient of the x term, and x is the x-coordinate of the vertex.

In this case,

a = 1 and b = -10, so:

x = -(-10)/(2 x 1) = 5

To find the y-coordinate of the vertex, we can substitute x = 5 into the function:

y = (5)² - 10(5) + 21 = -4

Therefore,

The vertex of the graph of the function is (5,-4).

I don’t understand? And it’s not 18,750

Answers

Net value (or the total of everything) is total revenue - total expenses.

Total revenue = $9,550

Total revenue = $9,000 + $200 = $9,200

Net value = $9550 - $9200 = $350

Since the total revenue is greater than the expenses, it is a profit.

So, Mia had a profit of $350

In the like terms column, the variables (the letters you see next to the numbers) are the same, and if they have an exponent the exponent is the same number too.

In the unlike terms column, they have different variables which means you can’t add or subtract them together. They also have different exponents, so you can’t add or subtract them either.


The coefficients can be different, but the variable and the degree of the variable must remain the same in order for it to be considered like terms. Hope this helped!

Simplify 3 square root of 512

Answers

Answer:

8

Step-by-step explanation:

not sure if this is what ur looking for sorry

The simplified form of 3√(512) using radical is 48√(2).

To simplify √(512), find the prime factorization of 512.

Prime factorization of 512:

512 = [tex]2^9[/tex]

Now, rewrite the square root as follows:

√(512) = √[tex](2^9)[/tex]

Next, use the property of square roots that states √(a * b) = √(a) * √(b):

√[tex](2^9)[/tex] = √([tex]2^8 * 2)[/tex]

         = √[tex](2^8) * \sqrt(2)[/tex]

Since √[tex](2^8)[/tex] is equal to [tex]2^4[/tex] then

√(512) = [tex]2^4[/tex] * √(2)

Finally, simplify √(2) as it is not a perfect square:

√(512) = [tex]2^4[/tex]* √(2)

          = 16 * √(2)

So, the simplified form is 48√(2).
