Answer:
1GET GOING3ALL MOST THEREYAY5THERE IS YO ANSWERS(1,3,5)the first floor of a house consists of a kitchen And dining room. The areas of the living room ,kitchen, and dining room are in the ratio of 3:2:1. The combined area of all three rooms is 576 square feet.
A. What is the area of the dining room?
B. What is the area of the kitchen?
C. What is the area of the living room?
Answer:
A: 96 B:192 C:288
Step-by-step explanation:
3+2+1=6
Divide 576 by 6 to get 1/6, you will get 96.
so 96 is the area of the dining room.
Multiply 2 times 96, since that would be 2/6.
That would be 192.
So 192 would be the area of the kitchen.
Here's a trick: all you need to do is add 96 and 192 now (or multiply 96 by 3), because that is half of the areas, 3/6.
So 96 times 3 is 288.
The living room is 288.
To check our work, we can add 288 by 96 by 192.
We would end up with 576, which was our original number.
So 288:192:96.

Explain how to find the zeros of the given polynomial: x3+3x2–x−3
What are the zeros?
Answer:
Step-by-step explanation:
The zero (root) of a function is any value of the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x-axis.
~~~~~~~~~
f(x) = x³ + 3x² - x - 3
f(-3) = ( - 3 )³ + 3( - 3 )² - ( - 3 ) - 3 = 0
f(-1) = ( - 1 )³ + 3( - 1 )² - ( - 1 ) - 3 = 0
f(1) = ( 1 )² + 3( 1 )² - ( 1 ) - 3 = 0
Answer:
The zeroes of the function are x = -3, x = -1, and x = 1.
Step-by-step explanation:
We are given a polynomial and asked to find the zeroes of the polynomial. Our given polynomial is:
[tex]x^3 + 3x^2 - x - 3[/tex]
The zeroes of a polynomial are the solutions or roots of the function. This is where if the line were graphed, the line would intersect the x-axis at those points (sometimes there will only be one).
This is a cubic polynomial. We can use a factoring technique referred to as grouping, which is most effective when factoring a trinomial with the only satisfaction met is: a > 1.
However, it can also be used when a > 1 is not true.
We can work with an example polynomial first and then work through solving the given polynomial.
An example polynomial would be:
[tex]10x^2 + 8x - 9 = 0[/tex]
In grouping, our main goal is to factor as quickly as possible. If you examine the polynomial, there is no common factor between 10x², 8x, or -9, so we cannot take out a GCF and need to use another factoring technique.
Since a > 1, we can instantly jump to using the grouping factoring technique.
Please note that the parent function for a quadratic is [tex]ax^2 + bx + c = 0[/tex].
To group:
We want to find the product of the terms a and c. So, with our example polynomial, a is 10, b is 8, and c is -9. Therefore, let's find the product of 10 and -9.Using ac, we will list all available factors. After doing this, we will find two factors of ac that will add up to give us b.These two factors are then substituted with b and c in the following parent equation: [tex]ax^2 + bx + cx + d[/tex].Finally, the equation is factored using parentheses in the following format: [tex](ax^2 + bx)(+ cx + d) = 0[/tex]After we group the function, we take the GCF out of both parentheses sets and write it as a coefficient to the remaining bit of the parentheses. The two GCFs are a set of terms and the remaining portion is the other set of terms.Let's use grouping to solve [tex]x^3 + 3x^2 - x - 3[/tex].
Because we already have four terms, we can skip steps one through three and go straight to step four.
[tex](x^3 + 3x^2)(-x - 3)[/tex]
Now, we need to take the GCF of both parentheses sets. Let's do this with our first set of terms.
You can divide x² out of both x³ and 3x², so x² is the GCF, leaving x and 3 behind.Then, we can also do this with our second set of terms.
There is a -1 implied in front of x, and there is no other common term between -x and -3, so -1 is our GCF, leaving x and 3 behind.Because our remaining terms for both sets match, we have grouped our polynomial correctly. Now, let's combine our GCFs into one term and list our common term as the second term.
[tex](x^2-1)(x+3)[/tex]
Now, we can break apart x² - 1 into more factors.
This is the difference of two squares. The formula for the difference of two squares is [tex](a^2-b^2)=(a+b)(a-b)[/tex]
Our perfect squares are every integer in the spectrum of numbers, so 1 is a perfect square. Therefore, x² becomes x and 1 becomes ±1.
Our new terms would therefore be [tex](x+1)(x-1)(x+3)[/tex].
Finally, to find zeroes of a function, x needs to equal something. Therefore, we can set our terms equal to zero and solve for x.
Term 1 (x + 1)
[tex]x + 1 = 0\\\\x + 1 - 1 = 0 - 1\\\\\boxed{x = -1}[/tex]
Term 2 (x - 1)
[tex]x - 1 = 0\\\\x - 1 + 1 = 0 + 1\\\\\boxed{x = 1}[/tex]
Term 3 (x + 3)
[tex]x + 3 = 0\\\\x + 3 - 3 = 0 - 3\\\\\boxed{x = -3}[/tex]
Therefore, our zeroes are listed above. To finalize our answer, we want to list them in increasing order, so this will be most negative to most positive. Therefore, our final answer is x = -3, -1, 1.

A rotating lawn is sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circle area of grass is 16 ft. Which measurement is the closest to the area in square feet that this sprinkler sprays with water?
Answer:
201.06 square feet.
Step-by-step explanation:
=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.
=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.
=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet

how do I write an equation of the trend line in slope intercept form?
Answer:
y=mx+b
Step-by-step explanation:
Answer:
You can see that it also uses the slope. You'll plug in your x1 and y1 along with the slope into the formula. Then you'll evaluate and rewrite it in the slope-intercept form by solving for the y variable. From this, we see that our equation for the trend line is y = (1/3)x + 2, and we are done!

Which equation could determine exactly how many times Haley can go through the funhouse?
Answer:
A. 49.79 = 1.19 + 0.25t
Step-by-step explanation:
One-time entrance fee to be paid by Haley as initial fee = $1.19
Going through the fun house each time would attract an additional fee of $0.25 each time they go through the fun house.
If Haley has $49.79, the number of times (t) Haley can go through can be expressed as:
Total amount Haley has = initial fee/entrance fee + additional fee per each time Haley goes through the fun house
The equation would be:
49.79 = 1.19 + 0.25t
