Answer:

You can't answer this because there isn't a regular x value, there is only a x squared

Step-by-step explanation:

Answers

Answer:

$8,051.62

Step-by-step explanation:

Compound interest formula

[tex]\sf A=P(1+\frac{r}{n})^{nt}[/tex]

where:

A = final amountP = principalr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsed

Given:

P = $5000r = 6% = 0.06n = 4t = 8

Substituting given values into the formula:

[tex]\implies \sf A=5000(1+\frac{0.06}{4})^{4 \times 8}[/tex]

[tex]\implies \sf A=5000(1.015)^{32}[/tex]

which is greater, 2,670 meters or 2 kilometers? explain.​

Answers

Answer: 2,670 meters

Step-by-step explanation:

2 kilometers = 2000 meters

2,670 > 2000

The greater value between  2,670 meters or 2 kilometers is 2,670 meters.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We are given that;

Two measurements  2,670 meters or 2 kilometers

Now,

To compare 2,670 meters and 2 kilometers, we need to convert them to the same unit of measurement.

There are 1,000 meters in a kilometer. So 2 kilometers is equal to:

2 km * 1,000 m/km = 2,000 meters

Now we can compare 2,670 meters and 2,000 meters. We can see that 2,670 meters is greater than 2,000 meters, because 2,670 is a larger number than 2,000.

Therefore, by conversion the answer will be 2,670 meters is greater than 2 kilometers.

Craig bought 8 folders and notebooks for school folders costs 50 cents and notebooks costs a $50 Craig spent a total of $6 how many folders and how many notebooks did he

Answers

The number of folders and notebooks in the equation is given by 3 and 5 respectively.

How to find number of folders and notebooks?

let

x = number of foldersy = number of notebooks

The equation:

x + y = 8

0.50x + 1.0y = 6

From (1)

x = 8 - y

Substitute x = 8 - y into (2)

0.50(8 - y) + 1.0y = 6

4 - 0.50y + 1.0y = 6

4 + 0.40y = 6

4 - 6 = -0.40y

-2 = - 0.40y

y = -2 / 0.40

y = 5

Recall

x + y = 8

x + 5 = 8

x = 8 - 5

Which of the following best describes the graph shown below ?

Answers

Answer:

B. This is the graph of a function, but it is not one-to-one

Step-by-step explanation:

A function is a type of graph that has a specific relationship between the x and y values.

Vocabulary

First, let's define the words that were used in the answer choices.

Function - A function is a type of relationship where the x-values do not repeat. This means that each x-value has only one specific y-value.One-To-One - A one-to-one function still has no repeating x-values; however, y-values also do not repeat. This means that each y-value has only one x-value and vice versa.

Finding a Function

There are different ways to find if a relationship is a function, but with a graph, the easiest way is the vertical line test. The vertical line test is when you draw vertical lines over your graph. If you are able to draw a vertical line everywhere without that line crossing the graph more than once, then the graph is a function.

In this graph, there is no spot in which a vertical line would intersect with the graph more than once. Since it passed the vertical line test, this must mean that x-values never repeat. Thus, this is a function.

Finding a One-To-One Function

Now that we know this is a function, we need to find if this is a one-to-one function. Once again, this can be done multiple ways, but one way is the horizontal line test. This test is similar to the method above; however, horizontal lines are used. In this test, you draw horizontal lines are drawn on the graph. If you can draw a horizontal line at every value without the line intersecting more than once, then it is a one-to-one function.

On this graph, if you were to draw a horizontal line at any of the y-values between 0 and 6, then the line would intersect multiple times. This means that y-values do repeat. Thus, this is not a one-to-one function.

Answer:

  x = -3, 0, or 7

Step-by-step explanation:

After removing common factors, the remaining quadratic can be factored by comparison to the factored form of a quadratic.

__

Step 1

Write the equation in standard form.

  4x³ -16x² -84x = 0

Step 2

Factor out the common factor from all terms.

  = 4x(x² -4x -21) = 0

Step 3

Compare to the factored form of a quadratic:

  (x +a)(x +b) = x² +(a+b)x +ab

This tells you the constants 'a' and 'b' in the factors can be found by considering ...

  (a+b) = -4 . . . . the coefficient of the x term of the quadratic

  ab = -21 . . . . . the constant term of the quadratic

It is often helpful to list factor pairs of the constant:

  -21 = (-21)(1) = (-7)(3) . . . . integer pairs that have a negative sum

The sums of these pairs are -20 and -4. We are interested in the latter. We can choose ...

  a = -7, b = 3

Step 4

Put it all together.

  4x³ -16x² -84 = (4x)(x -7)(x +3) = 0 . . . . . factored form of the equation

Step 5

Apply the zero product rule. This rule tells you the product of factors will be zero when one or more of the factors is zero:

  4x = 0   ⇒   x = 0

  x -7 = 0   ⇒   x = 7

  x +3 = 0   ⇒   x = -3

Solutions to the equation are x ∈ {-3, 0, 7}.

_____

Additional comment

What we did in Step 3 is sometimes referred to as the X-method of factoring a quadratic. The constant (ab product) is put at the top of the X, and the sum (a+b) is put at the bottom. The sides of the X are filled in with values that match the product and sum: -7 and 3. The method is modified slightly if the coefficient of x² is not 1.

Penelope has a bag that contains orange chews, apple chews, and lime chews. She performs an experiment. Penelope randomly removes a chew from the bag, records the result, and returns the chew to the bag. Penelope performs the experiment 33 times. The results are shown below:
A orange chew was selected 13 times.
A apple chew was selected 9 times.
A lime chew was selected 11 times.

Based on these results, express the probability that the next chew Penelope removes from the bag will be apple or lime as a percent to the nearest whole number.

Answers

The probability that the next chew Penelope removes from the bag will be apple or lime as a percent is 60.6%.

What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

Here, Number of apple and lime is 9 + 11 =20

Total bag contains = 13 + 9 + 11 = 33

Probability = Number of apple or line / Total

                   = 20 / 33

                   = 60.6 %

Thus, The probability that the next chew Penelope removes from the bag will be apple or lime as a percent is 60.6%.
