Mathematics

Norma-Jean [14]3 years ago
7 0

The price dropped by 0.08 dollars (subtract 3.20 and 3.12)

Divide this price drop over the original price

0.08/3.20 = 0.025 = 2.5%

<h3>The percent change is -2.5%</h3>

The negative is to indicate a price drop or decrease

--------------

If you want, you can use the formula below

P = 100*(N - S)/S

where N = 3.12 is the new price and S = 3.20 is the start price, so

P = 100*(N-S)/S

P = 100*(3.12-3.20)/3.20

P = -2.5%

we get the same answer as before

F(x) = x^2 + 7x-4 find the second derivative
Ulleksa [173]

We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.

This gives

f'(x) = 7

Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.

The ordered pairs in the table below represent a linear function.
ivann1987 [24]

Answer:

The slope is 2

Step-by-step explanation:

There's a theorem: \frac{y2-y1}{x2-x1} So lets put that into our equation.

\frac{9-3}{5-2} which also equals \frac{6}{3}

Then, all we must do is divide the nominator from the denominator.

6/3 = 2

Therefore, the slope is 2!

I hope this helps!
