ANSWER QUICKLY!!!!!
Given the polynomial function
f(x)=x3−4x2+x+6
1) Name all of the possible rational roots for the function using the Rational Root Theorem.
2) Prove 2 is one of the zeroes of this function (show or describe your process).
3) Name all of the actual roots of this function and describe how you found them.
4) Write the original polynomial function f(x)=x3−4x2+x+6 in factored form.
Answer:
1. The possible roots are ±1, ±2, ±3, ±6. These are the factors of the trailing constant (6) divided by the factors of the leading coefficient (1). When the leading coefficient is 1, the possible roots are the factors of the constant
2. The polynomial is easier to evaluate when it is written in Horner form:
f(x) = ((x -4)x +1)x +6
To show that 2 is a zero, we want to find f(2):
f(2) = ((2 -4)2 +1)2 +6 = (-4 +1)2 +6 = -6 +6 = 0
f(2) = 0, so 2 is one of the zeros of this function
3. Using synthetic division (attached) or polynomial long division, we can divide the given polynomial by (x-2) to find the remaining factors. This division gives (x^2 -2x -3), which can be factored as (x -3)(x +1), so the three actual roots are ...
x = 2 (from above), x = 3, x = -1 (from our factorization)
4. In factored form, the polynomial can be written ...
f(x) = (x +1)(x -2)(x -3)
The first factor was found from the fact that 2 was given as a zero of the function. For any zero "a", a factor of the polynomial is (x-a).
The remaining factors were found by factoring the quadratic trinomial that resulted from the division of f(x) by x-2. That trinomial is x^2 -2x -3.
There are a number of methods that can be used to factor x^2 -2x -3. Again, the rational root theorem can help. It suggests that ±1 and ±3 are possible roots.

4.8/(1 7/9)=(1.2b):6 2/3 I will mark as brainliest, i swear
Answer:
b = 15
Step-by-step explanation:
Answer:
b = 15
Step-by-step explanation:
Solve for b:
4.8/ 1 7/9 = 1.2b/6 2/3
Cross multiply:
6 2/3 * 4.8 = 1.2b * 1 7/9
6 * 3 + 2/3 * 4.8 = 1.2b * 9 + 7/9
20/3 * 48/10 = 12b/10 * 16/9
20 * 4 = b * 16/3
5 = b * 1/3
b = 5 * 3
b = 15

25² x 4² square root
Answer:
25.317977802344
Step-by-step explanation:
25x25= 625
4x4= 16
625+16= 641
The square root of 641 is 25.317977802344
n this case we are going to use the 'Babylonian Method' to get the square root of any positive number.
We must set an error for the final result. Say, smaller than 0.01. In other words, we will try to find the square root value with at least 1 correct decimal place.
Step 1:
Divide the number (641) by 2 to get the first guess for the square root.
First guess = 641/2 = 320.5.
Step 2:
Divide 641 by the previous result. d = 641/320.5 = 2.
Average this value (d) with that of step 1: (2 + 320.5)/2 = 161.25 (new guess).
Error = new guess - previous value = 320.5 - 161.25 = 159.25.
159.25 > 0.01. As error > accuracy, we repeat this step again.
Step 3:
Divide 641 by the previous result. d = 641/161.25 = 3.9751937984.
Average this value (d) with that of step 2: (3.9751937984 + 161.25)/2 = 82.6125968992 (new guess).
Error = new guess - previous value = 161.25 - 82.6125968992 = 78.6374031008.
78.6374031008 > 0.01. As error > accuracy, we repeat this step again.
Step 4:
Divide 641 by the previous result. d = 641/82.6125968992 = 7.7591072555.
Average this value (d) with that of step 3: (7.7591072555 + 82.6125968992)/2 = 45.1858520774 (new guess).
Error = new guess - previous value = 82.6125968992 - 45.1858520774 = 37.4267448218.
37.4267448218 > 0.01. As error > accuracy, we repeat this step again.
Step 5:
Divide 641 by the previous result. d = 641/45.1858520774 = 14.1858562034.
Average this value (d) with that of step 4: (14.1858562034 + 45.1858520774)/2 = 29.6858541404 (new guess).
Error = new guess - previous value = 45.1858520774 - 29.6858541404 = 15.499997937.
15.499997937 > 0.01. As error > accuracy, we repeat this step again.
Step 6:
Divide 641 by the previous result. d = 641/29.6858541404 = 21.5927760397.
Average this value (d) with that of step 5: (21.5927760397 + 29.6858541404)/2 = 25.63931509 (new guess).
Error = new guess - previous value = 29.6858541404 - 25.63931509 = 4.0465390504.
4.0465390504 > 0.01. As error > accuracy, we repeat this step again.
Step 7:
Divide 641 by the previous result. d = 641/25.63931509 = 25.0006678318.
Average this value (d) with that of step 6: (25.0006678318 + 25.63931509)/2 = 25.3199914609 (new guess).
Error = new guess - previous value = 25.63931509 - 25.3199914609 = 0.3193236291.
0.3193236291 > 0.01. As error > accuracy, we repeat this step again.
Step 8:
Divide 641 by the previous result. d = 641/25.3199914609 = 25.3159643039.
Average this value (d) with that of step 7: (25.3159643039 + 25.3199914609)/2 = 25.3179778824 (new guess).
Error = new guess - previous value = 25.3199914609 - 25.3179778824 = 0.0020135785.
0.0020135785 <= 0.01. As error <= accuracy, we stop the iterations and use 25.3179778824 as the square root.
So, we can say that the square root of 641 is 25.31 with an error smaller than 0.01 (in fact the error is 0.0020135785). this means that the first 2 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(641)' is 25.317977802344327.

At the movies, children's tickets are $6 each and adults' tickets are $10 each. Shandra buys 14 tickets. Let ᴀ be the number of adults going to the movies. Enter an algebraic expression in the box to represent the total price Shandra pays. Do not include the dollar sign in your answer.
Answer:
y=6x+10a
Step-by-step explanation:
let the number of children be x
and the number of adults be a
let the total price be y
given that children tickets are $6 each
also, an adult ticket is $10
x+a=14-------1
y=6x+10a----2
Therefore the expression for the total price can be expressed as
y=6x+10a
Write the equation of the line , in slope - intercept form , with following information : rate of change: -1 point : (3, - 3)
Answer:
y = -x
Step-by-step explanation:
Slope-intercept form looks like this: y = mx + b, with m being the slope or rate of change and b being the y-intercept. We already know the rate of change, so we can put -1 as m: y = -1x + b. To find our y-intercept, we can plug the point (3, -3) into the equation and solve for b:
-3 = -1(3) + b
-3 = -3 + b
b = 0
So we have y = -1x + 0. This can be simplified to y = -x.

9. The sum of three consecutive EVEN integers is 50 more than the third
integer. Find the integers.
Answer:
Step-by-step explanation:
The smallest integer is 2x - 2
The middle integer = 2x
The largest integer = 2x + 2
2x - 2 + 2x + 2x + 2 = 2x + 2 + 50 Combine
6x = 52 + 2x Subtract 2x from both sides
6x-2x = 52 Combine
4x = 52 Divide both sides by 4
4x/4 = 52/4
x = 13
The three integers are
2x - 2 = 24
2x = 26
2x + 2 = 28
Find the rate of change demonstrated in the graph below.
The rate of change of a graph, is the slope of the graph.
The rate of change of the graph is 4.5
The points on the graph are:
[tex]\mathbf{(x,y) = (2,9) (4,18)}[/tex]
So, the slope (m) is calculated as:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m = \frac{18 - 9}{4-2}}[/tex]
[tex]\mathbf{m = \frac{9}{2}}[/tex]
[tex]\mathbf{m = 4.5}[/tex]
Hence, the rate of change of the graph is 4.5

9514 1404 393
Answer:
1. x = {6, 16}
2. (x -8)² +(y +7/3)² = 64
Step-by-step explanation:
1. The distance formula is useful for this.
d² = (x2 -x1)² +(y2 -y1)²
13² = (x -11)² +(-5 -7)² . . . . . . . . fill in the given point coordinates
169 -144 = (x -11)² = 25 . . . . . . subtract 144
x -11 = ±5 . . . . . . . . . . . . . . . . . take the square root
x = 11 ±5 = {6, 16} . . . . . . . . . . add 11
The values of x that make the points 13 units apart are 6, 16.

2. The standard form equation of a circle is ...
(x -h)² +(y -k)² = r² . . . . . . circle centered at (h, k) with radius r
In order for the circle to be tangent to the y-axis, the radius must be equal to the distance the center is from the y-axis: the x-coordinate of the center point. That is, r = 8.
(x -8)² +(y +7/3)² = 64
