The remainder when f(x) is divided by x-1 is 0.
What is remainder theorem?Remainder Theorem states that given a polynomial function and a value for x, the remainder when the polynomial is divided by (x-a) is equal to the value of the polynomial when x=a. This theorem can be used to quickly and accurately find the remainder of a division problem, making it a very useful tool.
The remainder theorem states that if a polynomial f(x) is divided by x-a, then the remainder is f(a). In this case, we want to find the remainder when f(x) is divided by x-1. Therefore, we need to find f(1).
f(1) = 2(1)^(3) + 3(1)^(2) - 12(1) + 7
f(1) = 2 + 3 - 12 + 7
f(1) = 0

Part 1
In a race, 17 out of the 50 finished in less than 56 minutes. What percent of finished the race in less than 56 minutes? Write an equivalent fraction to find the percent
The percentage of people who participated in the race finished in less than 56 minutes is 34%. This can also be written as the equivalent fraction 34/100
To find the percentage of people who finished the race in less than 56 minutes, we can use the following formula:
percentage = (part/whole) x 100%
where "part" is the number of people who finished in less than 56 minutes, and "whole" is the total number of people who participated in the race.
In this case, we know that 17 people finished in less than 56 minutes, and there were 50 people in total. So we can plug these values into the formula:
percentage = (17/50) x 100%
percentage = 34%
Therefore, 34% of the people who participated in the race finished in less than 56 minutes.
To write an equivalent fraction for this percentage, we can write:
34% = 34/100
This is an equivalent fraction because 34/100 can be simplified to 17/50

Starting with a $500 investment, you would have approximately $6,795.70 after 40 years if the investment increases exponentially by about 15% every 2 years.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To find the future amount of the investment after 40 years, we can use the formula for compound interest:
Future Amount = Present Value x (1 + Interest Rate/Compounding Frequency)^(Compounding Frequency x Time)
In this case, the present value (PV) is $500, the interest rate (r) is 15%,
the compounding frequency (n) is 1 (since the interest is compounded every 2 years).
The time (t) is 40 years.
Plugging in the values, we get:
Future Amount = [tex]500 \times (1 + 0.15/1)^{(1 \times 40/2)}[/tex]
Future Amount = [tex]500 \times (1.15)^{20}[/tex]
Future Amount = [tex]500 \times 13.591409[/tex]
Future Amount = $6,795.70 (rounded to the nearest cent)
Therefore, starting with a $500 investment, you would have approximately $6,795.70 after 40 years if the investment increases exponentially by about 15% every 2 years.

Find the eigen values and eigen vectors of the matrix A=([2,2,0],[2,1,1],[-7,2,-3]).
The eigen values of the matrix A are 2, -2, and 7, and the corresponding eigen vectors are [1,1,2], [1,-2,0], and [2,1,1].
To find the eigen values and eigen vectors of the matrix A=([2,2,0],[2,1,1],[-7,2,-3]), we first need to find the characteristic equation of the matrix. This is done by finding the determinant of (A-λI), where λ is the eigenvalue and I is the identity matrix.
The characteristic equation is:
|A-λI| = |[2-λ,2,0],[2,1-λ,1],[-7,2,-3-λ]| = 0
Expanding the determinant, we get:
(2-λ)((1-λ)(-3-λ)-2) - 2(2(-3-λ)+7) + 0 = 0
Simplifying the equation, we get:
-λ³ + 6λ² - 5λ - 14 = 0
The eigen values are the roots of this equation. We can use the rational root theorem to find the possible rational roots of the equation, which are ±1, ±2, ±7, and ±14. By testing these values, we find that the eigen values are λ=2, λ=-2, and λ=7.
Now, we can find the eigen vectors by plugging the eigen values back into the equation (A-λI)v=0, where v is the eigen vector.
For λ=2, we get:
([2-2,2,0],[2,1-2,1],[-7,2,-3-2])v = 0
([0,2,0],[2,-1,1],[-7,2,-5])v = 0
The eigen vector for λ=2 is v = [1,1,2].
For λ=-2, we get:
([2+2,2,0],[2,1+2,1],[-7,2,-3+2])v = 0
([4,2,0],[2,3,1],[-7,2,-1])v = 0
The eigen vector for λ=-2 is v = [1,-2,0].
For λ=7, we get:
([2-7,2,0],[2,1-7,1],[-7,2,-3-7])v = 0
([-5,2,0],[2,-6,1],[-7,2,-10])v = 0
The eigen vector for λ=7 is v = [2,1,1].

Suppose z varies inversely with t and that z=6 when t=8. What is the value of z when t=2 ?
The value of z when t=2 is 24
The value of z varies inversely with t, which means that the product of z and t is a constant. We can write this relationship as:
zt = k
Where k is the constant. We are given that z=6 when t=8, so we can plug these values into the equation to find k:
6*8 = k
k = 48
Now we can use this value of k to find the value of z when t=2. Plugging in these values gives us:
z*2 = 48
Solving for z gives us:
z = 48/2
z = 24
Therefore, the value of z when t=2 is 24.

During a recent telethon, people pledged $25 or $50. Twice as many people pledged $25 as $50. Altogether, $18,000 was pledged. How many people pledged $25?
Answer:
360 people pledged $25.
Step-by-step explanation:
You'll need to set up only one equation to solve this.
Let's use x for the number of people who pledged $50. Since twice as many people pledged $25, it would be 2x. Keep this in mind for later.
Multiply 2x by 25, and you should get 50x. Now, your equation is 50x + 50x = 18,000. Simplify this to 100x = 18,000.
Now, divide both sides by 100. After doing so, you should have x = 180. This is how many people pledged $50. To find how many pledged $25, plug the value of x into 2x. (In other words, multiply 180 by 2.) After doing so, you should get 360. This is how many people pledged $25.

On a winter day adnan look up the current temperature in three nearby cities a adnan chooses two of the temperatures and writes a comparison what are all the possible compare says he can write
There are 9 possible comparisons that Adnan can write using the temperatures of the three nearby cities.
What are the Combinations?Combinations are the procedures used in mathematics to pick k things from n different items without replacement.
The following formula computes the combinations of k items from n:
(n, k) = n! / k!×(n-k)!
Let's say that Adnan looks up the current temperature in three nearby cities and writes down their temperatures as T1, T2, and T3.
To compare the temperatures, Adnan can choose any two of the temperatures and write a comparison of them.
Since there are three temperatures, there are a total of three possible pairs of temperatures that Adnan can choose:
1. T1 and T2
2. T1 and T3
3. T2 and T3
For each pair of temperatures, Adnan can write a comparison in one of three ways:
T1 is greater than T2 (T1 > T2)
T1 is less than T2 (T1 < T2)
T1 is equal to T2 (T1 = T2)
So, Adnan can write a total of nine possible comparisons of the temperatures:
T1 > T2,
T1 < T2,
T1 = T2,
T1 > T3,
T1 < T3,
T1 = T3,
T2 > T3,
T2 < T3, and
T2 = T3.
These are all the possible comparisons that Adnan can write using the temperatures of the three nearby cities.

Springfield avenue is 3 miles long. there are 8 sets of stop signs along Springfield avenue. the stop signs are the same distance apart . how far apart are the stop signs
The distance between the stop signs is 0.375 miles or roughly 0.6 kilometers.
distance between stop signs = 3 miles / 8
= 0.375 miles
What is the distance?
While distance and displacement appear to have the same meaning, they actually have very different definitions and implications. Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."
Distance is the sum of an object's movements, regardless of direction. The distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
The scalar quantity known as distance measures "how much ground an object has traversed" while moving.
From the question:
We can use the following calculation to calculate the separation between the stop signs:
distance between stop signs = total distance/number of intervals
There are 8 spaces between the stop signs and a total distance of 3 miles in this instance. As a result, we can determine the separation between the stop signs as:
distance between stop signs = 3 miles / 8
= 0.375 miles
As a result, there are 0.375 miles (or 0.6 kilometers) between each stop sign.

The cost of A Plus Advertising will be less than the cost of Print and More if the number of flyers to be printed and delivered is greater than 160.
Let's assume that the number of flyers to be printed and delivered is "x".
The cost of A Plus Advertising can be represented as:
Cost_A = 0.10x + 24
The cost of Print and More can be represented as:
Cost_P = 0.25x
To find out for how many flyers the cost of A Plus Advertising is less than the cost of Print and More, we need to set up an inequality:
Cost_A < Cost_P
0.10x + 24 < 0.25x
Subtracting 0.10x from both sides, we get:

Volume of a sphere = [tex]\frac{4}{3}[/tex] π r³, where r is the radius.
(a) Volume of fully inflated balloon = [tex]\frac{4}{3}[/tex] π (17)³
= [tex]\frac{19652}{3}[/tex]π inch³
(b) Volume of the half inflated balloon = Half of the fully inflated volume
= ([tex]\frac{19652}{3}[/tex]π / 2) inch³
= [tex]\frac{19652\pi }{6}[/tex] inch³
(c) Volume of half inflated balloon = [tex]\frac{19652\pi }{6}[/tex]
[tex]\frac{4}{3}[/tex] π r³ = [tex]\frac{19652\pi }{6}[/tex]
[tex]\frac{4}{3}[/tex] r³ = [tex]\frac{19652}{6}[/tex]
r³ = [tex]\frac{19652}{8}[/tex]
r = 13.49 inch
Hence the volume and radius are found.

The Amador family pays $7.50 per thousand cubic feet of natural gas. The total cost, t, varies directly as the number of thousand cubic feet of natural gas, g, used.
The constant of proportionality for the Amador family is obtained as k = 7.50.
What is a COP?The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.
If the cost t varies directly with the number of thousand cubic feet of natural gas g used, we can write -
t = kg
where k is the constant of proportionality, which represents the cost per thousand cubic feet of natural gas.
Since the Amador family pays $7.50 per thousand cubic feet of natural gas, we have -
k = 7.50
Therefore, the equation relating the total cost t to the number of thousand cubic feet of natural gas g used is -
t = 7.50g
This means that for every thousand cubic feet of natural gas used, the cost is $7.50.
If the Amador family uses 10,000 cubic feet of natural gas, the total cost would be -
t = 7.50(10) = $75
If they use 20,000 cubic feet of natural gas, the total cost would be -
t = 7.50(20) = $150
Therefore, the COP value is k = 7.50.
