perimeter of square = 4 length of its sides
x represents the side lengths
y represents the perimeter of the a square
y = ax + b
a = slope = y2-y1 / x2 -x1
= 8-4 / 2-1 = 4
y = 4x + b
from any point (1,4 )
4 = 4 .(1) + b

luke wants to buy an ipod. determine the equivalent cash price if luke makes 18 monthly payments of $31.48 at an interest rate of 15.2% compounded monthly
Answers
Answer:
We can use the formula for the present value of an annuity:
PV = PMT x [(1 - (1 + r)^(-n)) / r]
where PV is the present value, PMT is the monthly payment, r is the monthly interest rate, and n is the number of payments.
Substituting the given values, we have:
PV = $31.48 x [(1 - (1 + 0.152/12)^(-18)) / (0.152/12)]
PV = $31.48 x [(1 - 0.5159) / 0.0127]
PV = $1,007.97
Therefore, the equivalent cash price of the iPod is $1,007.97.

A salesperson had 360,000 dollars in sales last year, which is 40% of the sales she had this year. Which equation could be used to determine x, the salesperson’s total amount of sales, in dollars, for this year?
Answers
Answer: \(0.4x=360,000\)
Step-by-step explanation:
From the problem it can be seen that 360,000 is 40% of the sales she got this year. So, 40% of her sales is 360,000.
40% of x is mathematically 0.4 times x.
Therefore the equation you could use is: \(0.4x=360,000\)
If you want to solve this for x, simply divide 0.4 from both sides to get x by itself.
\(x=(\frac{360,000}{0.4})=900,000\)
So this year she made 900,000 dollars.

The side of a cube is measured as 11.4 centimeters with a possible error of + - (positive and negative) 0.04 centimeters. Give an estimate for the possible error in the value of the volume of the cube.
Answer: _________ cubic cm
Answers
Answer:
The volume of a cube is given by the formula V = s^3, where s is the length of a side of the cube. In this case, the length of a side is 11.4 centimeters with a possible error of + - 0.04 centimeters.
To find the possible error in the value of the volume of the cube, we can use the formula for the maximum error in a product:
max error in V = |V| * (max error in s / s)
where |V| is the absolute value of the volume, and max error in s is the maximum possible error in the measurement of the side.
Substituting the given values, we get:
max error in V = |11.4^3| * (0.04 / 11.4)
max error in V = 538.516 * 0.00351
max error in V = 1.89 cubic centimeters (rounded to two decimal places)
Therefore, the estimate for the possible error in the value of the volume of the cube is 1.89 cubic centimeters

Answer:
Step-by-step explanation:
If the roots are 7 and 3, then x = 7 and x = 3 are solutions. In factor form, x = 7 is (x - 7); in factor form, x = 3 is (x - 3). We FOIL these together to get
\(x^2-3x-7x+21\) which simplifies to
\(x^2-10x+21\) and we distribute in the 4:
\(4(x^2-10x+21)\) to get
\(4x^2-40x+84\) which is another way to write the last choice you're given.

The percentage of people taking the test who score below 335 is
Answers
Answer:
2.5%
Step-by-step explanation:
You want the percentage below 335 if the distribution is normal with a mean of 555 and a standard deviation of 110, using the empirical rule.
Z scoreThe z-score of 335 is ...
Z = (X -µ)/σ
Z = (335 -555)/110 = -220/110 = -2
DistributionThe empirical rule tells you that 95% of the distribution is between Z = -2 and Z = 2. That is, 5% of the distribution is evenly split between the tails Z < -2 and Z > 2. Half that value is in each tail.
P(X < 335) = 5%/2 = 2.5%
The percentage of people taking the test who score below 335 is 2.5%.

Using mid-term break formula.
Break the mid-term (8x) into such two terms that the product of which gives the side terms and sum or difference of which gives the second terms.x² × 12 = 12x²Choose such two terms the product of which gives 12x².We can use 6x and 2x since 6x + 2x = 8x (mid-term) and 6x × 2x = 12x² (side-terms)So, the equation becomes:x² + 6x + 2x + 12 = 0

The difference in overall loss or gain between sell at the current day's high price or low price is found tp be the difference in overall gain as $280.10
The third option is correct.
How do we calculate?For stock A:High price value: 115 shares * $105.19 per share = $12,084.85
Low price value: 115 shares * $103.25 per share = $11,858.75
For stock B:High price value: 30 shares * $145.18 per share = $4,355.40
Low price value: 30 shares * $143.28 per share = $4,298.40
The overall value at high price:
$12,084.85 + $4,355.40
= $16,440.25
The overall value at low price:
$11,858.75 + $4,298.40

Carlos is working two summer jobs, making $6 per hour walking dogs and making
$11 per hour clearing tables. In a given week, he can work no more than 14 total hours
and must earn no less than $110. If a represents the number of hours walking dogs
and y represents the number of hours clearing tables, write and solve a system of
inequalities graphically and determine one possible solution.
Answers
The system of inequalities graphically is given above.
One possible solution is (8.8, 5.2).
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
x = represents the number of hours walking dogs.
y = represents the number of hours clearing tables.
Now,
$6 per hour = walking dogs and making
$11 per hour = clearing tables.
Now,
No more than 14 total hours and must earn no less than $110.
We can make two inequalities.
x + y ≤ 14
6x + 11y ≥ 110
The graph is given below.
The intersection point from the graph is the one solution.
i.e
(8.8, 5.2)
or
x + y = 14
x = 14 - y
Substituting in 6x + 11y = 110.
6 (14 - y) + 11y = 110
84 - 6y + 11y = 110
5y = 110 - 84
5y = 26
y = 5.2
And,
x = 14 - 5.2
x = 8.8
Thus,
The system of inequalities graph is given above.
(8.8, 5.2) is the solution.

Classify each decreasing function as having a slope that is steeper or less steep than the slope of the function represented in this graph. y = - 4 3 x + 2 3 y = - 3 2 x + 1 2 y = - 2 x + 7 3 y = - 7 4 x + 3 2 y = - 8 7 x + 4 7
Answers
To compare the steepness of the slopes of different lines, we need to compare the absolute value of the coefficient of the x-term (the number in front of x) in each equation. A larger coefficient of x means a steeper slope, while a smaller coefficient of x means a less steep slope.
y = - 4 3 x + 2 3
The coefficient of x in this equation is - 4 3, this function has a steeper slope than the function y = - 3 2 x + 1 2
y = - 3 2 x + 1 2
The coefficient of x in this equation is - 3 2, this function has a steeper slope than the function y = - 2 x + 7 3
y = - 2 x + 7 3
The coefficient of x in this equation is - 2, this function has a steeper slope than the function y = - 7 4 x + 3 2
y = - 7 4 x + 3 2
The coefficient of x in this equation is - 7 4, this function has a steeper slope than the function y = - 8 7 x + 4 7
y = - 8 7 x + 4 7
The coefficient of x in this equation is - 8 7, this function has the least steep slope of all the functions.
So the order of the functions from steepest to least steep is: y = - 4 3 x + 2 3 , y = - 3 2 x + 1 2, y = - 2 x + 7 3, y = - 7 4 x + 3 2 , y = - 8 7 x + 4 7

Based on the population that the people were picked from, the probability that two people in a random sample drawn from 37,100,000 know each other is 0.0036.
What is the probability that the two people will know each other?Based on the fact that we have to find the probability that the two people might know each other if picked from 37,100,000 people, a probability of successful outcomes needs to be found.
A binomial probability formula is therefore the best model to use.
The probability that two people will know each other from 20 random people is:
= (20! / 2!(20-2)!) x (0.5²) x ((1-0.5)²⁰⁻²)
