<u>Domain is the </u><u>ALLOWED</u><u> x values in a function.</u>

  • Does plugging in any positive number pose a problem with getting an answer?

No.

  • Does plugging in 0 pose any problem?

No.

  • Does plugging in negative numbers pose any problem?

No. <em>Square root of negative numbers are not possible</em> BUT <em>cube root of negative numbers ARE possible</em>.

<em>Also, from the attached snapshot of the graph of f(x)=\sqrt[3]{x} , we can see that ALL real numbers are allowed for x</em>

12 times a number decreased by 5 is no more than 55
lions [1.4K]

Answer:

  12n -5 ≤ 55

Step-by-step explanation:

12 times a number (represented by n) is 12n.

"Decreased by 5" means 5 is subtracted from the product, giving 12n-5.

"Is no more than 55" means "is less than or equal to 55".

Then the expression written using math symbols is ...

  12n -5 ≤ 55

The length of the side of a square is equal to the perimeter of the square divided by four. Which shows the correct graph relati
serious [3.7K]

Answer:

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Step-by-step explanation:

Let

x ----> the perimeter of the square

y ---> the side length of the square

Remember that

The perimeter of the square is given by the expression

P=4b

where

b is the length side of the square

solve for b

b=\frac{1}{4}P

That means

A ordered  pair in the coordinate plane following the rule

(x,y) -----> (x,x/4)

The y-coordinate is equal to the x-coordinate divided by 4

y=x/4

therefore

On a coordinate plane, the x-axis is labeled Perimeter of a square, and the y-axis is labeled Side length of a square. A line goes through points (4, 1), (8, 2).

Because

For the point (4,1)

substitute in the linear equation the value of x

y=4/4=1 ----> is ok

For the point (8,2)

substitute in the linear equation the value of x

y=8/4=2 ----> is ok

What is the semiannual interest payments of a 30 year bond with a face value of $50 million and a stated annual interest rate of
Snowcat [4.5K]

Based on the stated annual interest rate and the face value of the bond, the semiannual payments will be $1,000,000.

<h3>How can the semiannual interest payment be found?</h3>

The formula to find the semiannual payment is:

= (Face value x Stated annual interest rate) / 2 semi-annual periods per year

Solving gives:

= (50,000,000 x 4%) / 2

= 2,000,000 / 2

= $1,000,000
