Step-by-step explanation:
There are 3 ways to find the other x intercept.
1) Polynomial Long Division.
Divide x^2 - 3x + 2 by the binomial x - 2, because by the Factor Theorem if a is a root of a polynomial then x - a is a factor of said polynomial.
2) Just solving for x when y = 0, by using the quadratic formula.
[tex]x^2 - 3x + 2 = 0\\x_{12} = \frac{3 \pm \sqrt{9 - 4(1)(2)}}{2} = \frac{3 \pm 1}{2} = 2, 1[/tex].
So the other x - intercept is at (1, 0)
3) Using Vietta's Theorem regarding the solutions of a quadratic
Namely, the sum of the solutions of a quadratic equation is equal to the quotient between the negative coefficient of the linear term divided by the coefficient of the quadratic term.
[tex]x_1 + x_2 = \frac{-b}{a}[/tex]
And the product between the solutions of a quadratic equation is just the quotient between the constant term and the coefficient of the quadratic term.
[tex]x_1 \cdot x_2 = \frac{c}{a}[/tex]
These relations between the solutions give us a brief idea of what the solutions should be like.

Write the equation of a function whose parent function, f(x) = x + 8, is shifted 2 units to the right.
g(x) = x − 6
g(x) = x − 2
g(x) = x + 2
g(x) = x + 6
Answer:
[tex]g(x)=x+6[/tex]
Step-by-step explanation:
we have
[tex]f(x)=x+8[/tex]
If f(x) is shifted 2 units to the right
then
The rule of the translation is
[tex]g(x)=f(x-2)[/tex]
so
[tex]g(x)=(x-2)+8[/tex]
[tex]g(x)=x+6[/tex]
Answer: The correct option is
(D) [tex]g(x)=x+6.[/tex]
Step-by-step explanation: Given that the following function is shifted 2 units to the right :
[tex]f(x)=x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to write the equation when the function (i) is shifted 2 units to the right.
We know that
if a function is shifted 2 units to the right, then its x co-ordinate is reduced by 2 units.
Therefore, the equation of the new function is given by
[tex]g(x)=f(x-2)=(x-2)+8=x+6.[/tex]
Thus, the required function is [tex]g(x)=x+6.[/tex]
Option (D) is CORRECT.

Identify an equation in point-slope form for the line perpendicular to
y= -2x + 8 that passes through (-3,9).
Answer:
y - 9 = 1/2(x + 3)
Step-by-step explanation:
For the equation y = -2x + 8, your slope, m, is -2. To find the slope for a line perpendicular to the original line, we do the opposite reciprocal of this number. The slope of the perpendicular line is 1/2.
Point-slope form is: y - y1 = m(x - x1) where x1 and y1 are the x- and y-coordinates of an ordered pair.
With this new slope for the perpendicular line, and the point we are given, we just plug in the info.
Your equation is: y - 9 = 1/2(x + 3)

How many permutations are there of the letters in the word 'PLANTS', if all the letters are used without repetition?
Answer:
6!
or
6*5*4*3*2*1
or
720
Step-by-step explanation:
The word 'PLANTS' contains no letter more than once.
It is say 6 letter word.
_ _ _ _ _ _
There are 6 ways to choose the first blank (after than there are 5 letters left to choose from)
After the first blank, there are 5 letter left to choose from so there are 5 ways to choose the second blank.
Then 4 ways for the third blank.
3 ways for the fourth blank.
2 ways for the fifth blank.
1 way for the sixth blank.
Now to figure out the number of permutations you must multiply the number of different ways we have above for each blank.
That is we are doing 6*5*4*3*2*1 or 6!
There are 720 different permutations of the letters in the word 'PLANTS' when used without repetition. This is calculated as the factorial of the number of letters, which is 6. Therefore, 6 factorial (6!) equals 720.
Explanation:The subject of the question falls under the topic of permutations in Mathematics. The question is asking for the number of different ways that the letters in the word 'PLANTS' can be arranged if all letters are used without repetitions. This is a concept in combinatorics, a subject of discrete mathematics that deals with counting and arranging objects.
To solve this, we need to calculate the factorial of the number of letters in the word 'PLANTS'. There are 6 letters in the word. The factorial of a number (denoted as n!) is the product of all positive integers less than or equal to that number. Therefore, the number of permutations is 6!, which equates to 6 x 5 x 4 x 3 x 2 x 1 = 720.
So, there are 720 different permutations of the letters in the word 'PLANTS' if all the letters are used without repetition.

A piggy bank contains some dimes and nickels. There are 8 more dimes than nickels in the bank. There is a total of $1.40. How many of each type of coin are in the bank?
This question is solved using a system of equations. I am going to say that:
x is the number of dimes.y is the number of nickels.Doing this, we get that: There are 4 nickels and 12 dimes.
There are 8 more dimes than nickels in the bank.
This means that: [tex]y = x + 8[/tex]
There is a total of $1.40.
Nickel is worth $0.05.Dime is worth $0.1.Thus, for the nickels:
[tex]0.05x + 0.1y = 1.4[/tex]
Since [tex]y = x + 8[/tex]
[tex]0.05x + 0.1(x + 8) = 1.4[/tex]
[tex]0.05x + 0.1x + 0.8 = 1.4[/tex]
[tex]0.15x = 0.6[/tex]
[tex]x = \frac{0.6}{0.15}[/tex]
[tex]x = 4[/tex]
For the dimes:
[tex]y = x + 8 = 4 + 8 = 12[/tex]
There are 4 nickels and 12 dimes.
A similar question is found at https://brainly.com/question/24342899
Final answer:
To solve the problem, we use algebra to express the relationship between the number of dimes and nickels and their total value in pennies. We find that there are 4 nickels and 12 dimes in the piggy bank.
Explanation:
Calculating the Number of Dimes and Nickels
Let's denote the number of nickels as N and the number of dimes as D. According to the problem, there are 8 more dimes than nickels, which means D = N + 8. Now, we need to convert the total value of coins into pennies because there are 100 pennies in one dollar.
The value of nickels and dimes in pennies is 5N (for nickels) and 10D (for dimes), respectively. Since the total amount is $1.40 or 140 pennies, we can express this as the equation 5N + 10D = 140.
Replacing D in the equation with N + 8 we get 5N + 10(N + 8) = 140. Simplifying this, we get 5N + 10N + 80 = 140, which simplifies further to 15N + 80 = 140.
Subtracting 80 from both sides gives us 15N = 60, and dividing both sides by 15 yields N = 4. This means there are 4 nickels.
To find the number of dimes, we substitute N with 4 in the earlier expression for D (D = N + 8) giving us D = 4 + 8, which equals 12.
Therefore, there are 4 nickels and 12 dimes.

Maria has a swimming pool in her backyard. Calculate the volume of the swimming pool. Round your answer to the nearest whole number. a0 cubic feet
Answer:
108 feet cubed
Step-by-step explanation:
i think its 24 because you do l*w*h so 4 times 6 equals 24, times 4.5 and its 108.
Answer : The volume of the swimming pool is, [tex]142ft^3[/tex]
Step-by-step explanation :
In the given figure, there are two figures are included which are cuboid and 2 hemisphere.
As we know that 2 hemisphere combine to form a sphere.
Volume of swimming pool = Volume of cuboid + Volume 2 hemisphere
Volume of swimming pool = Volume of cuboid + Volume sphere
Volume of swimming pool = [tex](l\times b\times h)+(\frac{4}{3}\pi r^3)[/tex]
where,
l = length of cuboid = 6 ft
b = breadth of cuboid = 4 ft
h = height of cuboid = 4.5 ft
r = radius of sphere = [tex]\frac{Diameter}{2}=\frac{4ft}{2}=2ft[/tex]
Now put all the given values in the above formula, we get:
Volume of swimming pool = [tex](l\times b\times h)+(\frac{4}{3}\pi r^3)[/tex]
Volume of swimming pool = [tex](6ft\times 4ft\times 4.5ft)+(\frac{4}{3}\times 3.14\times (2ft)^3)[/tex]
Volume of swimming pool = [tex]108ft^3+33.49ft^3[/tex]
Volume of swimming pool = [tex]141.49ft^3[/tex]
Volume of swimming pool ≈ [tex]142ft^3[/tex]
Therefore, the volume of the swimming pool is, [tex]142ft^3[/tex]

Janelle and her best friend Carmen go shopping. the function p(t) = 5^4-3x^3 +2^2+24 represents how much money each girl spent based on the number of hours they were shopping. If Janelle and Carmen each go shopping for 2 hours how much money did they spend together.
$58
$62
$176
$124
The answer is:
They spent $176 together.
Why?We are given an expression which represents the money spent for each girl, it's a function of time and it will show how much they can spend in terms of hours.
Assuming that you have committed a mistake writing the equation, otherwise, the given options would not fit, the expression is:
[tex]p(t)=5x^{4}-3x^{3}+2x^{2}+24[/tex]
Now, from the statement we know that the function represents how much money each girl spent, so, if we need to calculate how much money they will spend together, we need to multiply the expression by 2, so we have:
[tex]p(t)=2(5x^{4}-3x^{3}+2x^{2}+24)[/tex]
Then, calculating the spent money for 2 hours, we need to substitute the variable "x" with 2.
Calculating we have:
[tex]p(2)=2(5*(2)^{4}-3*(2)^{3}+2*(2)^{2}+24)=2(5*16-3*8+2*4+24)[/tex]
[tex]p(2)=2(5*16-3*8+2*4+24)=2(80-24+8+24)=2*88=176[/tex]
Hence, we have that they spent $176 together.

Answer:
r = ∛(3V/4π)
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³.
We want to solve this first for r³ and then for r.
Multiplying both sides of V = (4/3)πr³ by 3 yields an equation without fractions: 3V = 4πr³.
Dividing both sides of this equation by 4π isolates r³:
3V
r³ = -------
4π

3V
r³ = -------
4π
obtaining r = ∛(3V/4π)
[tex]\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\ \cline{1-1} V=113 \end{cases}\implies 113=\cfrac{4\pi r^3}{3}\implies 339=4\pi r^3 \\\\\\ \cfrac{339}{4\pi }=r^3\implies 26.98\approx r^3\implies \sqrt[3]{26.98}=r\implies 2.999 \approx r\implies \stackrel{\textit{rounded up}}{3=r}[/tex]

A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target. What is the area, in square inches, of the target?
Area of a circle is found using the formula: Area = π * r^2
Using 3.14 for π
Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.
This is 20% of the entire target.
To find the area of the entire target, divide the area of the bull's eye by the percentage:
Area = 12.56 / 0.20 = 62.8 square inches.
Round the answer as needed.
Answer:
Area of target = 62.8 inch²
Step-by-step explanation:
A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target.
Diameter of bull's eye = 4 inch
[tex]\texttt{Area of bull's eye = }\frac{\pi\times 4^2}{4}=12.56inch^2[/tex]
Given that bull’s-eye covers 20% of circular target.
[tex]\texttt{Area of bull's eye = }\frac{20}{100}\times \texttt{Area of target}\\\\\texttt{Area of target}\times 0.2=12.56\\\\\texttt{Area of target}=\frac{12.56}{0.2}=62.8inch^2[/tex]
Area of target = 62.8 inch²

Answer:
The x-intercept is (6,0).
The y-intercept is (0,-21/2).
Step-by-step explanation:
So we are told this is a line.
Linear equations in the form y=mx+b tell us the slope,m, and the y-intercept,b.
So we are going to write our equation in this form to determine x- and y- intercept.
Let's begin.
First thing I'm going to is compute the slope. The slope can be found by lining up the points vertically and subtracting them vertically then put 2nd difference over 1st difference.
Let's do that:
( -10 , -28)
- ( -6 , -21)
-----------------------
-4 -7
So the slope is -7/-4 which is 7/4.
Now we know our equation to be in this form
y=(7/4)x+b
Use one of the points along with y=(7/4)x+b to find b.
Doesn't matter which one, you get to choose.
How about (-2,-14)?
-14=(7/4)(-2)+b
-14=-7/2+b
Add 7/2 on both sides:
-14+7/2=b
-21/2=b
So our equation is
[tex]y=\frac{7}{4}x-\frac{21}{2}[/tex]
So we already know the y-intercept is (0,-21/2).
We knew this because we were putting into slope-intercept form.
Now to find the x-intercept, set y=0 and solve for x:
[tex]0=\frac{7}{4}x-\frac{21}{2}[/tex]
Clear the fractions; multiply both sides by 4:
[tex]0=7x-42[/tex]
Add 42 on both sides:
[tex]42=7x[/tex]
Divide both sides by 7:
[tex]\frac{42}{7}=x[/tex]
So x=6
The x-intercept is (6,0).

For 2a., you have to set it up like this: csc 48° = 20⁄x [OR sin 48° = ˣ⁄20]. Then you would have to isolate the variable by getting rid of the denominator. The cosecant function has an extra step because you will get xcsc 48° = 20. As stated, isolate the variable; this time, divide by csc 48°. This is what 20 will be divided by to get your x, whereas the other side cancels out. Then you have to round to the nearest tenth degree.
For 2b., you have to set it up like this: sec 39° = ˣ⁄12 [OR cos 39° = 12⁄x. Then you would have to isolate the variable by getting rid of the denominator. The cosine function has an extra step because you will get xcos 39° = 12. As stated, isolate the variable; this time, divide by cos 39°. This is what 12 will be divided by to get your x, whereas the other side cancels out. Then you have to round to the nearest tenth degree.
For 2c., you have to set it up like this: cot 64° = 15⁄x [OR tan 64° = ˣ⁄15]. Then you would have to isolate the variable by getting rid of the denominator. The cotangent function has an extra step because you will get xcot 64° = 15. As stated, isolate the variable; this time, divide by cot 64°. This is what 15 will be divided by to get your x, whereas the other side cancels out. Then you have to round to the nearest tenth degree.
Now, for 3., it is unique, but similar concept. In this exercise, we are solving for an angle measure, so we have to use inverse trigonometric ratios. So, we set it up like this: cot⁻¹ 1⅗ = m<x [OR tan⁻¹ ⅝ = m<x]. We simply input this into our calculator and we get 32,00538321°. When rounded to the nearest degree, we get 32°.
WARNING: If you use a graphing calculator, you have to input it uniquely because most graphing calculators do not have the inverse trigonometric ratios programmed in their systems. This is how you would write this: tan⁻¹ 1⅗⁻¹. You set 1⅗ to the negative first power, ALONG WITH the inverse tangent function, because without it, your answer will be thrown off. Since Cotangent and Tangent are multiplicative inverses of each other, that is the reason why the negative first power is applied ALONG WITH the inverse tangent function.
**NOTE: 1⅗ = 8⁄5
Take into consideration:
sin θ = O\H
cos θ = A\H
tan θ = O\A
sec θ = H\A
csc θ = H\O
cot θ = A\O
