A quadratic function and an exponential function are graphed below. How do the decay rates of the functions compareover the inte
Kobotan [32]

To check the decay rate, we need to check the variation in y-axis.

Since our interval is

-2We need to evaluate both function at those limits.At x = -2, we have a value of 4 for both of them, at x = 0 we have 1 for the exponential function and 0 to the quadratic function. Let's call the exponential f(x), and the quadratic g(x).[tex]\begin{gathered} f(-2)=g(-2)=4 \\ f(0)=1 \\ g(0)=0 \end{gathered}

To compare the decay rates we need to check the variation on the y-axis of both functions.

\begin{gathered} \Delta y_1=f(-2)-f(0)=4-1=3 \\ \Delta y_2=g(-2)-g(0)=4-0=4 \end{gathered}

Now, we calculate their ratio to find how they compare:

\frac{\Delta y_1}{\Delta y_2}=\frac{3}{4}

This tell us that the exponential function decays at three-fourths the rate of the quadratic function.

And this is the fourth option.

Tatiana wants to give friendship bracelets to her 32 classmates. She already has 5 bracelets, and she can buy
Aloiza [94]

4p+5=32 or 7 packages

I got this because there are 4 bracelets in one package and she doesn't know how many packages she needs so we put p for packages next to the 4 and you already have 5 so you add the 5 to it, all of that should come out to 32. If the equation wasn't what you were looking for you subtract 5 from 32 and get 27, then you divide 4 by 27 and you get 6.75, then you round it up and you get 7. The number of packages she needs is 7.

Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under \$50$50dollar sign, 50
myrzilka [38]

Answer:

k

Step-by-step explanation:

Let k represent the price in dollars at which Nita will buy the keyboard.

We have been given Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.

This means that Nita will buy the computer, when its price (k) is less than $50. We know that sign < represents less than.

We can represent our given information in an inequality as:

k

Therefore, our required inequality would be k.
