Keywords:
Polynomial, variable, coefficients, constant term.
For this case, the first thing we must do is rewrite the polynomial in a standard way. For this, we reorder the polynomial coefficients.
The standard form of the polynomial is:
[tex]ax ^ 2 + bx + c[/tex]
Where,
a, b, c: are the coefficients of the polynomial.
x: is the variable
Rewriting the polynomial we have:
[tex]3x ^ 2-5x + 2[/tex]
Comparing with the standard form we have that the values of the coefficients are given by:
[tex]a = 3\\b = -5\\c = 2[/tex]
Answer:
The values for the coefficients and constant term are:
[tex]a = 3\\b = -5\\c = 2[/tex]
Answer:

Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b.
What is an equivalent equation solved for h?
h = (– b)÷ r
h = – b ÷ r
h = ÷ r – b
h = ÷ r
Answer:
a
Step-by-step explanation:
Final answer:
The equivalent equation solved for h is h = -b/r. To derive this equation, we can isolate h in the given equation p = 0.7(rh + b) by multiplying both sides by the reciprocal of 0.7, distributing, and simplifying, option n 2 is correct.
Explanation:
The equivalent equation solved for h is h = −b ÷ r.
To derive this equation, we need to isolate h in the given equation p = 0.7(rh + b). We can start by multiplying both sides of the equation by the reciprocal of 0.7, which is 1.4286 (approximately).
Then, we can distribute the 1.4286 to the terms inside the parentheses to get p = 1.4286rh + 1.4286b. Next, we can subtract 1.4286b from both sides of the equation to isolate the 1.4286rh term.
Finally, we can divide both sides of the equation by 1.4286r to solve for h, which gives us the equivalent equation h = −b ÷ r.

Katrina is 69.75 inches tall. Her best friend, Allison, is 64.85 inches in height. How many inches taller is Katrina than Allison?
A) 4.10
B) 4.90
C) 5.10
D) 5.90
Answer: B) 4.90
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Katrina: 69.75 inches tall Allison: 64.85 inches tall.Since Katrina is taller than Allison, to calculate the how many inches taller is Katrina than Allison, we have to subtract Allison’s height to Katrina’s height:
Mathematically speaking:
69.75 -64.85 = 4.9 inches.

in a certain class, the ration of passing grades to failing grades is 9 to 3. If 17 grades were failing, how many passing grades were there?
Final answer:
The ratio of passing to failing grades in the class is 3 to 1. With 17 failing grades, we can determine there were 51 passing grades by setting up a proportion and solving for the number of passing grades.
Explanation:
The question relates to the ratio of passing grades to failing grades and asks us to find the number of passing grades if there are 17 failing grades. The ratio given is 9 to 3, which simplifies to 3 to 1 (since both 9 and 3 are divisible by 3). This means for every 3 passing grades, there is 1 failing grade.
Since there are 17 failing grades and the ratio of failing to passing is 1 to 3, we can set up a proportion to find the number of passing grades (p):
1/3 = 17/p
Multiplying both sides by p and then by 3 gives us:
3 × 17 = 1 × p
51 = p
Therefore, there were 51 passing grades.

in the drawing six out of every 10 tickets are winning tickets of the winning tickets one out of every three awards is a larger prize what is the probability that a ticket is randomly chosen will award a larger prize
The probability that a randomly chosen ticket will award a larger prize is calculated by multiplying the probability of getting a winning ticket with the probability that the winning ticket is for a larger prize, which results in a 20% chance.
Explanation:The question is seeking to determine the probability that a ticket chosen at random from a raffle will award a larger prize. We are given that 6 out of every 10 tickets are winning tickets, and of those winning tickets, 1 in every 3 is for a larger prize. To find this probability, we need to multiply the probability of a ticket being a winner by the probability of the winning ticket awarding a larger prize:
Probability of a winning ticket = 6/10 or 0.6Probability of a larger prize if it's a winning ticket = 1/3 or approximately 0.333Now, we multiply these probabilities:
Probability of a larger prize = Probability of winning ticket × Probability of a larger prize given a winning ticket
Probability of a larger prize = 0.6 × 0.333
Probability of a larger prize = 0.2 or 20%

Describe how the graph of y=log (10 000x) is related to the graph of y=log x
graph of y=log (10 000x) is related to the graph of y=log x is transposed by 4 units.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given graphs of y=log (10 000x)
y equal to ten thousand of x
We know a property of log.
logab=loga+logb
Log ab equal to log a plus log b.
So log (10 000x) =log 10000+log x
=4+logx
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
So the graph of log (10 000x) is transposed by 4 units.
Hence graph of y=log (10 000x) is related to the graph of y=log x is transposed by 4 units.

If x > 1, then which of the following has the LEAST value?
If x > 1, then the expression (0.25 - x) will have the least value when x is equal to 1.
Explanation:If x > 1, then the expression (0.25 - x) will be negative. When comparing negative values, the one with the least absolute value will have the least value. Therefore, to find the expression with the least value, we want to find the largest negative value for (0.25 - x). Since x > 1, the largest negative value for (0.25 - x) would occur when x is closest to its minimum value, which is 1. Therefore, the expression (0.25 - x) will have the least value when x is equal to 1.

Joey Chestnut is trying to break his own world record for eating the most hot dogs and buns in 10 minutes. He needs to eat more than 72 hot dogs to break his record. After 1 minute of competition, Joey has eaten 10 hot dogs. Joey wants to know the number of hot dogs per minute that he needs to eat for the next 9 minutes to break his own record.
Joey Chestnut needs to eat more than 6.89 hot dogs per minute for the next 9 minutes to break his record of 72 hot dogs.
Explanation:To find the number of hot dogs per minute Joey Chestnut needs to eat in the remaining 9 minutes to break his record, we need to start by calculating how many more hot dogs he needs to surpass 72 hot dogs. Since he has already eaten 10 hot dogs in the first minute, he needs to eat more than 62 hot dogs in the next 9 minutes to break the record.
We calculate the average number of hot dogs per minute by dividing the remaining number of hot dogs by the number of minutes left. So,
Number of hot dogs needed > 72 hot dogs - 10 hot dogs = 62 hot dogsMinutes remaining = 9 minutesHot dogs per minute needed = Number of hot dogs needed / Minutes remainingHot dogs per minute needed > 62 hot dogs / 9 minutes ≈ 6.89 hot dogs per minuteTo break his record, Joey Chestnut needs to eat more than 6.89 hot dogs per minute for the next 9 minutes.

Joey Chestnut wants to break his record of eating more than 72 hot dogs in 10 minutes. After the first minute, he has already eaten 10 hot dogs. We need to find out how many hot dogs per minute he needs to eat for the remaining 9 minutes to break his record.
First, determine the number of hot dogs Joey needs to eat in total to break the record:

Next, calculate the number of hot dogs he still needs to eat after the first minute:
[tex]\[73 - 10 = 63 \text{ hot dogs}\][/tex]
Since he has 9 minutes remaining, we need to find the number of hot dogs per minute he needs to eat:

Sales tax on an item is directly proportional to the cost of the item purchased if the tax on a $600 item is $36 what is the sales tax on a $950 item?
The sales tax on the item costs $950 is $57.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Given that, the cost of the item purchased if the tax on a $600 item is $36.
Now, rate of sales tax =36/600 ×100
= 6%
The sales tax on a $950 item is
6% of 950
= 0.06×950
= $57
Hence, the sales tax on the item costs $950 is $57.
