4,-24,144,-864,... whats the 8th term in the sequence?


Are 24 and 864 supposed to be negatives?

If so, that means that each term is multiplied by negative 6.
So, 4 times -6 = -24. Then -24 x -6 = 144. And so on.

So -864 x -6 = 5,184. (5th term)
5,184 x -6 = -31,104. (6th term)
-31,104 x -6 = 186,624. (7th term)
186,624 x -6 = -1,119,744. (8th term)

I think, and hope, that it is correct. Hope this helps! :)

Whats the product of 86 and the depth of the river?

Here is how you are going to get the answer:

Let the depth of the river = d

So in order to find the product, you simply multiply

so the product of 86 and the depth of the river would be 86 * d

or 86d.

Hope this answers your question. Have a great day!

Algebraic terms are separated by ______. Choose all that apply. 1)= 2)+ 3)x 4)÷ 5)-

Answer

1)=

2)+

5)-

Explanation

When letter or numbers are separated by multiplication or division can be combined to make one term.

In an algebra equation, terms are separated by an addition sign, subtraction sign or an equal sign. For example,

3a + 7b = 21.

This equation have 3 terms.

Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term. 7x3y3 + 4 − 11x5y2 − 3x2y

For the answer to the question above,  the power of "y" doesn't influence descending order for x even if it is higher than power of x.

Unordered polynomial is 
7x3y3 + 4 - 11x5y2 - 3x2y

Polynomial in descending order  looks like this
-11x5y2 + 7x3y3 - 3x2y + 4

Degree of the second term is 5 ( because of x5 )

Which polynomial expression represents the area of the outermost square tile, shown below? A square shaped tile with length x plus three is shown x2 + 6x + 6 x2 + 9x + 6 x2 + 6x + 9 x2 − 6x + 9

I believe the correct answer from the choices listed above is the third option. The polynomial expression that represents the area of the outermost square tile would be x^2 + 6x + 9. The area of a square is calculated by the square of its side and the side of this square is given as x+3.

A = (x+3)^2 = x^2+6x+9

Which answer describes the type of sequence? −99, −88, −66, −55, ... A. arithmetic B. neither arithmetic nor geometric C. geometric

Here, Geometric ratio, r = -88/-99 or -66/-88 which is 8/9 or 6/8. As they are not equal, it is not a geometric.

Now, Arithmetic difference, d = -88-(-99) or -66-(-88) which is 11 or 22. As they are not equal, it is not a Arithmetic.

So, it's neither an Arithmetic nor a Geometric.

Option B is your answer!

Hope this helps!

I don't really understand slope. I mean I sorta do and I sorta don't. I don't know how to determine the rate of change, unless it's meaning the Time = minute

The slope of a line tells us how something changes over time. If we find the slope we can find the rate of change over that period of change means.  
A great website that could help you understand this is http://www.algebra-class.com/rate-of-change.html. But I can help you with this.

Hailey has a summer job at the water slide park. She earns $9.50 an hour as a lifeguard, but never works more than 25 hours in a week. She determines that her salary is modeled by the function s = 9.5h. What is the domain of this function in this situation? A) s ≤ 237.50 B) all real numbers C) {0 ≤ h ≤ 25} D) {0 ≥ h ≥ 25}

Answer: C)  {0 ≤ h ≤ 25}

Step-by-step explanation:

  • The domain of a function is the set of all values for independent variable for which the function must be defined.

Given: The amount earned by Hailey for one hour work =$9.50

She determines that her salary is modeled by the function s = 9.5h.

Here h is the independent variable such that 's' is dependent on 'h'.

Since she never works more than 25 hours in a week.

Therefore, the maximum hours she will work = 25

Hence, the domain of this function in this situation is {0 ≤ h ≤ 25}, where h is number of hours she works.

Working together, Rocco and Giulia can paint a room in 3 hours. It would have taken Rocco 7 hours to do the job alone. Which equation can be used to determine r, Giulia’s rate of work in parts per hour?

For the answer to the question above, Guilia at the rate of 1/r can finish the job expressed in the following equation. 1/3 = 1/7+1/r.
Getting r, r is equal to
5.25 hrs. Hence, Guilia can do painitng alone in 5.25 hrs.
