We have to divide polynomial given as (x³ - 21x² + 147x - 343) by (x - 7) by synthetic division.
7 | 1 -21 147 -343
↓ 7 -98 343

Therefore, quotient is (x² - 14x + 49) and the remainder will be 0.
Option (3) will be the answer.
Quickly for the brainiest one and 6 points plus 5 stars.
Answer:
Find out how much is 1
Multiply 1/2 by 2 to get 1 and multiply 14 by 2 so the ratio is equal
1/2 x 2 = 1
14 x 2 = 28
so 1 = 28
Multiply everything 28
I'm pretty sure I have it in order clockwise
3/14 x 28 = 84/14 = 6/1 = 6
1/14 x 28 = 28/14 or 2
5/7 x 28 140/7 = 20
3/7 x 28 = 84/7 = 12
2/7 x 28 = 56/7 = 8
1/7 x 28 = 28/7 = 4
3/4 x 28 = 84/4 = 21
1/4 x 28 = 28/4 = 7
I'm guessing the middle would be 1 is 28

A bag has one white, two black, three red and four green marbles. If a single marble is randomly drawn from this bag, what is the probability it is black or white? Express your answer as a common fraction.
Answer:
3/10
Step-by-step explanation:
This is mutually exclusive, meaning they cannot happen at the same time, you cannot pickup a marble and it cant be both black and white. So all we do now is just add the probabilities of getting a black marble and white marble
P(picking a black marble) = 2/10
P(picking a white marble) = 1/10
Add them
2/10 + 1/10 = 3/10
7. In 2015 a club has 250 members who each
pay
$95 annual subscription.
In 2016 the membership increases by 4% and the annual subscription is
increased by 6%. What is the total income from subscriptions in 2016?
2015:
250 members
$95 annual subscription
2016
250 members + 4%
$95 annual subscription + 6%
Work:
250 x 1.04 = 260
95 x 1.06 = 100.7
260 x 100.7 = 26,182
Thus, the club makes $26,182 from 260 members who pay a subscription of $100.7
To model the problem containing an unknown number, translate the statement into an equation. Sixteen is five less than a number. Which steps would you take to translate the statement? .
Answer:
21; steps are included:
Step-by-step explanation:
lets put this unknown number as a variable (n)
now lets write the equation out: (n=the unknown number)
16 = n-5
To keep the equation balanced we add 5 to both sides:
16+5=n-5+5
21=n
Now that means the unknown value is 21
Hope this helped
Answer:
16 = x - 5
Step-by-step explanation:
We start with 16. We then hear "is", which means equals. So we put an equal sign. Next, we hear "five less then", which means we will subtract 5 from something. We then learn the something will be an unknown number, which we will represent with the variable x. Now we write subtraction of 5 from x. 16 = x - 5
What is the product of (-a + 3)(a + 4)?
Answer:
-a^2 -a + 12
Step-by-step explanation:
You have to multiply all four together.
-a times a = -a^2
-a times 4 = -4a
3 times a = 3a
3 times 4 = 12
Add them all together =
-a^2 - a + 12
The answer is :
-a^2-a+12
Step-by-step explanation:
-a(a) is -a
-a(4) is -4a
3(a) is 3a
3(4) is 12
So,
-a^2-4a+3a+12
Simplify
-4a+3a is -a bcz -4+3 is -1
Final answer
a^2-a+12

Simon has 160160160 meters of fencing to build a rectangular garden. The garden's area (in square meters) as a function of the garden's width xxx (in meters) is modeled by A(x)=-x(x-80)A(x)=−x(x−80)A, left parenthesis, x, right parenthesis, equals, minus, x, left parenthesis, x, minus, 80, right parenthesis What width will produce the maximum garden area?
The width for maximum area will be 40 metres.
Given,Simon has 160 metres of fencing to build a rectangular garden.
The garden's area (in square meters) as a function of the garden's width x(in meters) is modeled by,
[tex]A(x)=-x(x-80)[/tex].
We know that perimeter of rectangle will be,
[tex]P=2(L+B)\\[/tex]
Here p is 160,
So,[tex]160=2(L+B)[/tex]
[tex]\L+B= 80[/tex]
Now we have the sum of length and width off the rectangular garden is 80.
Since,
[tex]A(x)=-x(x-80)\\[/tex]
So, [tex]A(x)=x(80-x)[/tex]
We know that the area of rectangle will be the product of length and , here in question width is [tex]x[/tex] so the length will be[tex](80-x)[/tex].
Now we have to calculate the width for which the area will be maximum.
The area will be maximum when the first derivative of area function will becomes zero.
So,
[tex]\frac{\mathrm{d} }{\mathrm{d} x} A(x)=\frac{\mathrm{d} }{\mathrm{d} x}(-x)(x-80)[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=\frac{\mathrm{d} }{\mathrm{d} x}(-x^{2} +80x)[/tex]
[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=-2x+80\\[/tex]
For maximum area ,
[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=0[/tex]
Hence,
[tex]-2x+80=0\\x=40[/tex]
Hence the width for maximum area will be 40 metres.

The maximum area is 1600 sq meters.
Step-by-step explanation:The garden's area is modeled by a quadratic function, whose graph is a parabola.
The maximum area is reached at the vertex.
So in order to find the maximum area, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into A(x).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
A(x)=0 -x(x-80)=0
↓ ↓
-x=0 or x-80=0
x=0 or x=80
Now let's take the zeros' average:
[tex]\frac{(0)+(80)}{2}=\frac{80}{2}=40[/tex]
The vertex's x-coordinate is 40. Now lets find A(40):
A(40)= -(40)(40-80)
= -(40)(-40)
= 1600
in conclusion, the maximum area is 1600 square meters.

Find the values of y = p(x) = √x for x = 0, 1.44, 2.25, 3.24, 4.41, 5.29.
Answer:
The correct answers are:
[tex]\sqrt{0}=0\\\sqrt{1.44} = \pm 1.2\\\sqrt{2.25} = \pm 1.5\\\sqrt{3.24} = \pm 1.8\\\sqrt{4.41} = \pm 2.1\\\sqrt{5.29} =\pm 2.3[/tex]
Step-by-step explanation:
Given the function:
[tex]y=p(x)=\sqrt{x}[/tex]
That means, the value that we give as input i.e. the value of x is square rooted and given as output.
Input is x and output is [tex]\sqrt x[/tex].
Now, calculating the outputs for different values of x:
1. x = 0, the square root of 0 is always 0.
so, y = p (0) = 0
2. x = 1.44
[tex]y = p(1.44)=\sqrt{1.44} \\\Rightarrow \sqrt{\dfrac{144} {100}}\\\Rightarrow \pm \dfrac{12} {10} = \pm 1.2[/tex]
Similarly other square roots can be calculated:
3. x = 2.25
[tex]y = p(2.25)=\sqrt{2.25} \\\Rightarrow \sqrt{\dfrac{225} {100}}\\\Rightarrow \pm \dfrac{15} {10} = \pm 1.5[/tex]
4. x = 3.24
[tex]y = p(3.24)=\sqrt{3.24} \\\Rightarrow \sqrt{\dfrac{324} {100}}\\\Rightarrow \pm \dfrac{18} {10} = \pm 1.8[/tex]
5. x = 4.41
[tex]y = p(4.41)=\sqrt{4.41} \\\Rightarrow \sqrt{\dfrac{441} {100}}\\\Rightarrow \pm \dfrac{21} {10} = \pm 2.1[/tex]
6. x = 5.29
[tex]y = p(5.29)=\sqrt{5.29} \\\Rightarrow \sqrt{\dfrac{529} {100}}\\\Rightarrow \pm \dfrac{23} {10} = \pm 2.3[/tex]
Hence, The correct answers are:
[tex]\sqrt{0}=0\\\sqrt{1.44} = \pm 1.2\\\sqrt{2.25} = \pm 1.5\\\sqrt{3.24} = \pm 1.8\\\sqrt{4.41} = \pm 2.1\\\sqrt{5.29} =\pm 2.3[/tex]

Solve: -4 < -2x < 10
Explanation:
The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"
-4 < -2x < 10
-4/(-2) > x > 10/(-2) .... inequality signs flip
2 > x > -5
-5 < x < 2
This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.
