Answer 1

whats your question

Answer 2

Megan and Julie are stuck simplifying radical expressions. Megan has to simplify the quantity of x to the one third power, over x to the one twelfth power. Julie has to simplify the thirty second root of the quantity of x times x to the second times x to the fifth. Using full sentences describe how to fully simplify Megan and Julie’s expressions. Describe if Megan and Julie started with equivalent expressions or if they started with expressions that are not equal.

Answer 3

i jus need to see if my resonses are right

Answer 4

what are your responses

Answer 5

When dividing radicals with fraction powers, you want to divide the higher number from the lower number and diving x with x giving you x^1/4.

When you solve the second equation, you want to multiply all the x's in the radical and add their powers. When you multiply variables with powers, you always want to add the powers. Once simplified, 32 radical x^8 can also be written as x^1/4 because 8 goes in 4 times with 32. Megan and Julie started out with the same equivalent expression because once you rewrite the second equation to a radical expression it equals.

Answer 6

yea you are right

okay can you check my others please

Answer 8

yea

Answer 9

When solving a radical equation, Amari and Justin came to two different conclusions. Amari found a solution, while Justin's solution did not work in the equation.

Create and justify two situations: one situation where Amari is correct and a separate situation where Justin is correct.

Answer 10

When solving a radical expression, you can have multiple answers when solved. You can get an answer and plug it in to the original equation and it must equal to each other. It is important to always plug in your answers. When Amari came with an answer with a solution and Justin did not. He simply made sure that the numbers plugged in and where equal As for Justin, he got an answer that when you plug in, it gives you no solution. Vice versa, when Justin is correct and Amari has no solution. These are called extraneous solutions. When you get multiple answers but not all work.

Answer 12

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.


•When f(x) becomes f(x) − 3
•When f(x) becomes −2 • f(x)

Answer 13

When written as f(x) -3, this means that it has affected the y-intercept. Since it is a negative, it moves down the y intercept by 3. This affects even and odd because it tells us if the graph moves up or down. If positive it moves up and is negative it moves down. In this case, we have a negative 3 so we move it down three times.

When written as -2 times f(x), this tells us where it shifts on the x intercept. This affects even and odd because it tells us where it shifts to the left or the right. Like the y-intercepts, the even and odds are affected because negatives shift to the left and positives shift to the right. The number -2 will shift to the left because it is a negative.

Answer 14

your right

Answer 15

An architect for a golf course wants to plan a sand trap that passes between a tree and a cart path. Using these as the focus and directrix, how can the architect plan a parabolic sand trap that will be equidistant from the tree and the cart path at all times? Describe your method in full sentences.

Answer 16

The sand trap will have curve of the parabola. The equation can be written as y = a(x - h)^2 + k. The points (h,k) refer to the vertex and the (x,y) refers to the designed coordinates. The focus is at (Fx, Fy) and the directrix is y, p = 1/2 (Fx - y). The (a) can be 1/4 p rewriting the equation y = [1/2(Fx - y)](x - h)^2 + k.

Answer 20

Christi needs your help on the last question of her math homework. The question reads, "How can key features be used to create a sketch of any polynomial function?"

Explain to Christi, in complete sentences, what key features are necessary and how they can be used to create the sketch of a polynomial function.

Answer 21

There are many key features that affect the final sketch of the function. The highest degree can tell you how many zeroes. Polynomial functions have a maxima and a minima. They are the smallest and largest values of the function. Symmetry can be useful to see how the function reflects on the axis. Inflection is a point in which the function curves change. They are stationary points and are not to be confused with the maxima and minima.

Answer 23

Jordan is a manager of a car dealership. He has 3 professional car washers to clean the entire lot of cars, Jennifer, Arianna, and Matthew. Jennifer can wash all the cars in 14 hours. Arianna can wash all the cars in 11 hours. Matthew is new to the car dealership, so no one knows how long it will take him.

Hayden assigns all of them to wash the cars together. Explain to Jordan how this task can tell her how long it would take Matthew to complete the task if he worked by himself. Use complete sentences.

Answer 24

You can set up the equation like this:
1/A=1/14+1/11+1/M. All means the amount of them together and M meaning the unvalued time that it would take Matthew. Jordan the manager can find the total amount of cars opposed to the time overall it took to find how long it takes Matthew to wash all the cars.
