I need help on number 5

Answers

Answer 1

Answer: A fraction is undefined if its denominator is zero, because then it's saying
"Division by zero !" which is a definite no-no.

Can the denominator of the fraction in #5 ever be zero ?

The denominator is a quadratic polynomial. Do you know
how to solve (a quadratic polynomial) = 0 ?

This problem is even easier than that, because it gives you some choices.
So you don't even have to solve the quadratic equation. All you have to do
is check out the choices.
Do you see choice of 'x' values that make the denominator zero ?

Big sloppy hint: Look at choice-E very very carefully.

Is that enough help ?

Kwikset Enterprises sold 300 shares of stock at $12.34 per share. The underwriting commission was 5.8%. To the nearest cent, how much did Kwikset Enterprises make on its sale of stock, after subtracting the underwriting commission?

Answers

Kwikset has 300 shares in the stock. He sold it for 12.34 dollars per share:
So:
=> 300 * 12.43 dollars = 3702 dollars is the total money that she get after selling the stocks.
Now, it will be deducted by 5.8% commission.
=> 3702 * .058 = 214.716
=> 3702 - 214.716 = 3487.284 dollars
or -3487.28 dollars.

Is this graph a function

Answers

Answer:

To determine if a graph is a function, we need to check if each input (x-value) has a unique output (y-value). We can do this by performing the vertical line test.

Here's how you can determine if a graph is a function using the vertical line test:

1. Imagine drawing a vertical line anywhere on the graph.

2. If the vertical line intersects the graph at more than one point, then the graph is not a function.

3. However, if the vertical line intersects the graph at only one point, then the graph is a function.

So, if you have a specific graph in mind, you can visualize drawing vertical lines and see if they intersect the graph at more than one point. If they do, then the graph is not a function. If each vertical line intersects the graph at only one point, then the graph is a function.
