Answer:

Square root means to find what multiplied by itself gets the number shown.

5 x 5 = 25 so the square root of 25 is 5.

3 x 3 = 9 so the square root of 9 is 3.

3 + 5 = 8

8 is the answer

Answer:

\boxed{8}

Step-by-step explanation:

Simplify  \: the  \: following :  \\ =  >  \sqrt{25}  +  \sqrt{9}  \\  \\\sqrt{25}  =  \sqrt{ {5}^{2} }  = 5:  \\ =  > 5 +  \sqrt{9}  \\  \\ \sqrt{9}  = \sqrt{ {3}^{2} }   = 3:  \\ 5 + 3 \\  \\ 5+3=8:  \\ Answer:8

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!

Answer:

Twelve tickets cost $30 --> True

Thirty tickets cost $12 --> False

Each additional costs $2.50 --> True

The table is a partial rep --> True

ordered pairs --> False

Step-by-step explanation:

Twelve tickets cost $30 --> True, you can literally see that in the table

Thirty tickets cost $12 --> False, 30 is not in the table so you don't have that information. Besides, $12 is an unlikely low value for so many tickets.

Each additional costs $2.50 --> True, you can see the difference in the TotalCost column to be consistently 2.50.

The table is a partial rep --> True, values below 11 are not shown for example.

ordered pairs --> False --> Then the x value should be first, e.g., (11, 27.50), since the cost y is a function of the number x.

Given the functions f(n) = 500 and g(n) = (nine tenths)n − 1, combine them to create a geometric sequence, an, and solve for the
masya89 [10]

Answer:

A(n) = 500 * (\frac{9}{10})^{n-1

A(11) = 174.34

Step-by-step explanation:

Given

f(n) = 500

g(n) = (\frac{9}{10})^{n-1

Represent the combination of f(n) and g(n) with A(n)

So, we have:

A(n) = f(n) * g(n)

This gives:

A(n) = 500 * (\frac{9}{10})^{n-1

To calculate the 11th term, we make use of n = 11

A(11) = 500 * (\frac{9}{10})^{11-1

A(11) = 500 * (\frac{9}{10})^{10

This gives:

A(11) = 500 * (0.9)^{10}

A(11) = 500 * 0.3486784401

A(11) = 174.33922005

Approximate to 2 dp

A(11) = 174.34

Suppose someone tells you that she has a triangle with sides having lengths 2.6, 8.1, and 8.6. Is this a right triangle? Why or
Lunna [17]
This is not a right triangle as 2.6 squared plus 8.1 squared does not equal 8.6 squared (Pythagorean theorem)
