Final answer:
The number 59 is prime, and the trinomial a^2 - 4a + 4 is a perfect square trinomial.
Explanation:
Prime number: The number 59 is prime because it is only divisible by 1 and itself, while the other numbers have factors other than 1 and themselves.
Perfect square trinomial: The trinomial a2 - 4a + 4 is a perfect square trinomial because it can be factored to (a - 2)(a - 2), making it a square of a binomial.

The step function f(x) is graphed. What is the value of f(0)? -2 -1 0 1
Answer: -2 is the correct answer
Explanation:
This is the graph for greatest integer function by looking at the graph we can clearly conclude that f at zero is giving the value -2
Greatest integer function gives the value that is less than or equal to the value taken inside the function
For example if we have 2.09 and is operating under greatest integer function the value comes out to be 2 because it will convert the decimal value in integer
denoted as [2.09]=2
can u guys show me how 58 is the right answer? i need to see where i went wrong so please include the whole process.
NMO = LMO = x+34
LMO = 1/2 of LMN
so 2(x+34) = 6x-28
2x+68 = 6x-28
2x +96 = 6x
96 = 4x
x =96/4 = 24
x = 24
LMO = x+34 = 24+34 = 58
since NMO = LMO, NMO = 58

the function a(b) relates The area of a trapezoid with a given height of 12 and one base length of 9 with the length of its other base
The equation that represents the function B(a) as the length of the side parallel to the base is B(a) = a/6 - 9, as per the area of a trapezoid.
What is the area of a trapezoid?If the length of two parallel sides of a trapezoid is 'a', 'b' and the height of that trapezoid is 'h', then the area of a trapezoid can be represented as
= [(a + b)h]/2
Given, the base of the trapezoid is 9 and the height of the trapezoid is 12.
Therefore, 'b' is the parallel side of the base.
The given function that represents the area of the trapezoid is:
A(b) = [12(b + 9)]/2
Let, A(b) = a.
Therefore, a = [12(b + 9)]/2
⇒ 2a = 12(b + 9)
⇒ a = 6(b + 9)
⇒ a = 6b + 54
⇒ 6b = a - 54
⇒ b = (a - 54)/6
⇒ b = a/6 - 9
If we assume the length of the side parallel to the base 'b' = B(a), therefore, the equation will be:
B(a) = a/6 - 9

Joel borrowed $18,000 for 6 years at simple interest to purchase a vehicle. If Joel repaid a total of $20,953.80, at what rate did he borrow the money?
Joel borrowed money at an interest rate of approximately 2.73%. This was determined by using the simple interest formula to calculate the interest paid over 6 years and then re-formulating to find the interest rate using the known principal amount and time period.
Explanation:The subject of this question is simple interest which is a concept in Mathematics. The question is asking for the interest rate at which Joel borrowed money to purchase a vehicle. By knowing that Joel borrowed $18,000, repaid a total of $20,953.80 after 6 years, and by applying the simple interest formula I = PRT (where I is interest, P is principal amount, R is interest rate and T is time in years), we can find out the interest rate.
The first step is to calculate the simple interest itself, which can be found by subtracting the original principal amount from the total amount repaid. So, $20,953.80 - $18,000 = $2,953.80 is the interest paid over 6 years.
Then we rearrange the simple interest formula to solve for the rate: R = I / (PT). Substituting the known values, our equation is: R = $2,953.80 / ($18,000 * 6), which gives R = 0.027325, or approximately 2.73% when expressed as a percentage.

Inga lives 3 miles more than twice as far from school as Brent does. If Brent lives b miles from school then Inga lives ____ miles from school
Inga lives 2b + 3 miles from school, where b is the distance Brent lives from school in miles.
Therefore, the distance that Inga lives from school, in terms of b, is 2b + 3 miles.
Explanation:The problem states that Inga lives 3 miles more than twice the distance that Brent lives from school. If the distance Brent lives from school is b miles, this can be expressed algebraically as 2*b (twice the distance of Brent) + 3 (the extra 3 miles that Inga lives). Therefore, the distance that Inga lives from school, in terms of b, is 2b + 3 miles.

Why would the owner withdraw assets from other cash?
Answer:
The owner of a business sometimes withdraw assets other than cash because cash is more liquid and can be used in transactions easily, whereas the assets after a period of times becomes liable of depreciation.
The depreciation on assets decreases the amount of the assets based on the time and wear and tear of the tangible assets.
Therefore, to retain some liquid assets in hand the tangible or intangible assets are used first.
Hence, the businessman here did the right thing.

Michael owns a lawn care service. He charges each customer 30 + 12h dollars, where h represents the number of hours spent working on a lawn. What does each part of the expression represent? Drag the answer into the box to match each part of the expression.
The linear expression 30 + 12h represents Michael's lawn care service charges, where '30' is the fixed fee and '12h' is the variable fee depending on the hours worked.
Explanation:Michael's lawn care service uses an equation to calculate the charges for his customers: 30 + 12h dollars, where h represents the number of hours spent working on a lawn. In this expression, the number 30 represents a fixed fee, likely covering base expenses such as equipment, transportation, or administrative costs. The term 12h represents the variable fee, where 12 is the hourly rate in dollars Michael charges for his labor, and h is the number of hours he works on the lawn.
Thus, to determine the total cost to a customer, one would multiply the number of hours Michael works (h) by his hourly rate (12) and then add the fixed fee (30). For instance, if Michael works 5 hours on a lawn, the total cost would be calculated as follows: 30 + 12(5) = 30 + 60 = 90 dollars.

Jeremy saves $35 per month over the first 7 months of the year. He saves $40 per month over the next 5 months of the year. If Jeremy spends none of his savings, which expression shows how many dollars he will have saved by the end of the year?
Answer: The expression shows the number of dollars he will have saved by the end of the year is given by [tex]35(7)+40(5)=\$445[/tex]
Step-by-step explanation:
Since we have given that
Amount he saved per month over the first 7 months = $35
Amount he saved per month over the next 5 months = $40
So, total saving by the end of the year is given by
[tex]35\times 7+40\times 5\\\\=\$245+\$200\\\\=\$445[/tex]
Hence, the expression shows the number of dollars he will have saved by the end of the year is given by

A hummingbird can travel up to 15 meters per second. What is the hummingbirds speed in miles per hour? 1 mile = 1609 meters
Answer:
33.56 miles per hour.
Step-by-step explanation:
First we will see how many meters the hummingbird can travel in an hour (in meters)
it can travel up to 15 meters per second, but we know that one hour has 3600 seconds ( because an hour has 60 minutes of 60 seconds each one ( 60 x 60 = 3600)
So the hummingbird can travel 3600 x 15 = 54,000 meters in one hour.
Now, we know that 1 mile = 1609 meters, so in order to convert the 54,000 meters in miles per hour we're going to use a rule of three.
1 mile ----------- 1609 meters
x miles ---------- 54,000 meters
x miles = 54,000/1,609 = 33.56
Therefore, the hummingbird speed is 33.56 miles per hour.
To rent a bike there is a set fee, plus an hourly rate. Renting a bike for 4 hours costs $24. Renting it for 7 hours costs $37.50. How much to rent it for 3 hours?
By solving a system of linear equations, the set fee for renting a bike is determined to be $6 and the hourly rate is $4.50. Hence, the cost to rent the bike for 3 hours is $19.50.
Explanation:The question involves creating linear equations based on the given information to find the cost of renting a bike for a certain number of hours. We are told that renting a bike for 4 hours costs $24 and renting for 7 hours costs $37.50. We can express this situation with two equations, where x represents the set fee and y represents the hourly rate:
4y + x = 247y + x = 37.5We solve this system of equations to find the values of x and y. Subtracting the first equation from the second gives us 3y = 13.5, hence y = 13.5 / 3 = $4.50 per hour. We can then substitute y back into the first equation: 4(4.50) + x = 24, which simplifies to 18 + x = 24, hence x = $6.
To rent the bike for 3 hours, the cost would be 3(4.50) + 6 = $13.50 + $6 = $19.50.
