Given polynomials are,
[tex]\rm{f(x)=x^2+px+q}[/tex]
[tex]\rm{g(x)=x^2+mx+n}[/tex]
According to Remainder Theorem, if (x + a) is a factor of f(x), then,
[tex]\longrightarrow\rm{0=f(-a)}[/tex]
[tex]\longrightarrow\rm{0=(-a)^2+p(-a)+q}[/tex]
[tex]\longrightarrow\rm{0=a^2-pa+q\quad\dots(1)}[/tex]
Similarly, if (x + a) is a factor of g(x), then,
[tex]\longrightarrow\rm{0=g(-a)}[/tex]
[tex]\longrightarrow\rm{0=(-a)^2+m(-a)+n}[/tex]
[tex]\longrightarrow\rm{0=a^2-ma+n\quad\dots(2)}[/tex]
Subtracting (2) from (1),
[tex]\longrightarrow\rm{0=(a^2-pa+q)-(a^2-ma+n)}[/tex]
[tex]\longrightarrow\rm{0=a^2-pa+q-a^2+ma-n}[/tex]
[tex]\longrightarrow\rm{0=(m-p)a+q-n}[/tex]
[tex]\longrightarrow\rm{0=(m-p)a-(n-q)}[/tex]
[tex]\longrightarrow\rm{(m-p)a=n-q}[/tex]
[tex]\longrightarrow\rm{\underline{\underline{a=\dfrac{n-q}{m-p}}}}[/tex]

Given f(x)=(0.5)^x, give the rule for g(x) if it is f(x) shifted to the left 1 unit, down 3 units, and reflected over the x-axis
Answer:
g(x) = -(0.5)^(x + 1) + 3
Step-by-step explanation:
First, let's define the transformations used in this case:
Horizontal shift (horizontal translation):
If we have a function f(x), a horizontal translation can be written as:
g(x) = f(x - N)
if N is positive, the translation is to the right
if N is negative, the translation s to the left.
Vertical shift (vertical translation):
If we have a function f(x), a vertical translation can be written as:
g(x) = f(x) + N
if N is positive, the translation is upwards
if N is negative, the translation is downwards.
Reflection over the x-axis.
If we have a function f(x), a reflection over the x-axis is written as:
g(x) = -f(x).
Now we have the function:
f(x) = (0.5)^x
Let's apply the transformations:
"shifted to the left 1 unit"
g(x) = f(x - (-1) ) = f(x + 1)
"shifted down 3 unts"
g(x) = f(x + 1) - 3
"reflected over the x-axis"
g(x) = -( f(x + 1) - 3 ) = -f(x + 1) + 3
now we can replace the function equation here and get:
g(x) = -f(x + 1) + 3 = -(0.5)^(x + 1) + 3

What is the measure of each side? NEED HELP ASAP
Answer:
Each side is 5 units long
Step-by-step explanation:
Since the opposite angles are equal then x + 2 = 3x - 4
So solve for x: so 4+2 = 3x - x
6 = 2x
3 = x
So one side is x + 2 = 3 + 2 = 5
The other side is 3x - 4 = 3(3) - 4 = 9-4 = 5

William has a coin and a spinner, shown below. He can flip heads or tails on the coin and spin numbers 1 through 8 on the spinner. He flips the coin once and spins the spinner once. What is the probability that the coin will land on heads and the spinner will land on an odd number?
Answer:
1/4
Step-by-step explanation:
Coin sample Space = {H, T}
Spinner sample space = {1, 2, 3, 4, 5, 6, 7, 8}
Probability that coin lands on head :
P(H) = 1 /2
Probability that spinner lands on odd number :
Odd numbers = {1, 3, 5, 7} = 4
P(spinner lands on odd) = 4 / 8 = 1/2
Hence, probability that the coin will land on heads and the spinner will land on an odd number = (1 /2 * 1/2) = 1/4

Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
convertir 26 grados celsius a grados a grados fahrenheit
Answer:
Para transformar 26 °C a grados Fahrenheit tienes que multiplicar 26 x 9/5 y después sumarle 32. 1 °C son 33,8 °F.
Step-by-step explanation:
26 degrees Celsius is equal to 78.8 degrees Fahrenheit.
To convert 26 degrees Celsius to degrees Fahrenheit, you can use the following formula:
°F = (°C × 9/5) + 32
Plug in the value of celsius.
°F = (26 × 9/5) + 32
°F = (234/5) + 32
°F = 46.8 + 32
°F = 78.8
Therefore, 26 degrees Celsius is equal to 78.8 degrees Fahrenheit.

A rectangular landing pad measures 20' × 25' with a rectangular target on the pad measuring 6' × 8'. What is the geometric probability that a model rocket falling randomly on the pad will land in the target?
Answer:
9.6%
Step-by-step explanation:
The probability that a model rocket falling randomly on the pad will land in the target is 9.6% if the rectangular landing pad measures 20' × 25' with a rectangular target on the pad measuring 6' × 8'.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have a rectangular landing pad measures 20' × 25' with a rectangular target on the pad measuring 6' × 8'.
To get the geometric probability, we must find the area of the rectangle.
Total outcomes = 20' × 25' = 500'
Total favourable outcomes = 6' × 8' = 48'
Probability = 48/500 = 0.096
= 0.096×100 = 9.6%
Thus, the probability that a model rocket falling randomly on the pad will land in the target is 9.6% if the rectangular landing pad measures 20' × 25' with a rectangular target on the pad measuring 6' × 8'.

Which situation best represents the equation below x-15=60
Answer:
The correct answer is C. That problem best represent x - 15 =60.
Answer:
C
Step-by-step explanation:
So lets look at the first equation.
This would represent 60-15=x
This is because 60 shells minus 15 shells she gave away.
Next is B, whihc is also 60-15=x
This is because Mr yungs brother is 60 years old and mr yung is 15 years younger.
Next is c, whihc is 60+15=x
This is because they had 60, gave 15 already, and want to find out what they started with.
FInally we are left with d.
This is 15+x=60
Well...none of those look like x-15=60
But lets go back to c:
60+15=x
Lets try to rwwrite this.
Subtract 15 from both sides, and you get:
60=x-15
Just make this proper by putting the x-15 before the 60:
x-15=60
That looks like x-15=60
Now we know our answer!
C

inch wide and \frac{11}{16}
16
11
inch long.
Answer:
[tex]A=\dfrac{121}{8}\ in^2[/tex]
Step-by-step explanation:
There are 44 rectangular stickers
Length of each sticker= (1/2) inch
The width of each sticker = (11/16) inch
We need to find the area of the all stickers. The area of a rectangle is given by :
[tex]A=l\times b\\\\A=44\times \dfrac{1}{2}\times \dfrac{11}{16}\\A=\dfrac{121}{8}\ in^2[/tex]
So, the area of all stickers is equal to [tex]\dfrac{121}{8}\ in^2[/tex].

find the product (x+3y^2) (3x-3y^2)
Answer:
3x^2 - 12x·y^2 - 9y^2·y^4
Step-by-step explanation:
Apply the distributive property of multiplication here.
x times (3x - 3y^2) is 3x^2 - 3x·y^2.
3y^2 times (3x - 3y^2) is 9x·y^2 - 9y^2·y^4.
Thus, the desired product of the given binomials is the sum of the above results:
3x^2 - 3x·y^2 - 9x·y^2 - 9y^2·y^4
which shortens to 3x^2 - 12x·y^2 - 9y^2·y^4
