All the sides add like a rectangle with two sides measuring 4 and two measuring 2 so you would add 4+4+2+2=12

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.

Jada surveyed some students to see which tool they most favored for communicating with grit. The results of her survey are shown

nikklg [1K]

Answer:

120 students did Jada survey

Step-by-step explanation:

* Lets explain how to solve the problem

- The results of Jada survey are shown in this circle graph

# Communication tools Text messages 5/12

# Phone 1/5

# Emails 1/20

# Other messaging apps 1/3

- A total of 50 students said they favored text messages to

communicate with friends

- We need to find the total number of the students in Jada survey

- Assume that the total number of the students in the survey is x

∵ The Communication tools Text messages expressed by a

fraction 5/12 of the circle graph

∵ The total of 50 students said they favored text messages to

communicate with friends

- That means The fraction $\frac{5}{12}$ of x equivalent to 50

∴ $\frac{5}{12}*x=50$

- Multiply both sides by 12

∴ 5x = 600

- Divide both sides by 5

∴ x = 120

∵ x represents the number of the students in Jada survey

∴ 120 students did Jada survey

The cost of renting a community center is $100, with an additional cost of $10 per guest.

Marysya12 [62]

Step-by-step explanation:

The number of guests is the independent variable and should be between 1 and 50. We can use a scale of 10's

The cost is the dependent variable and the minimum cost is 100 and should rise from there

The scale would be from 100 's

Evaluate the numerical expression. − 1 3 − (− 4 9 )

notka56 [123]

Two negatives make a positive so, -13 - (-49) equals -13 + 49, or 49-13, they are all the same thing, all equal to 36.
