The vertex form of the equation of a parabola is given to be:
\(y=a(x-h)^2+k\)where
\((h,k)\Rightarrow\text{ Vertex coordinates}\)The question provides the vertex coordinates to be:
\((h,k)=(7,4)\)Substituting this value into the vertex form equation, we get:
\(y=a(x-7)^2+4\)We are given the coordinates of a point on the parabola to be:
\((x,y)=(5,16)\)We can use this point to get the value of a in the vertex formula by substituting into the equation:
\(\begin{gathered} 16=a(5-7)+4 \\ 16-4=a(-2)^2 \\ 12=4a \\ a=\frac{12}{4} \\ a=3 \end{gathered}\)Therefore, the vertex form of the equation of the parabola is given to be:
\(y=3\mleft(x-7\mright)^2+4\)Which polynomial represents the difference below? 10x^8 + 11x^6 - 2x + 5 - (8x8 + 6x7 - 5)
Answer:
\(2x^8-6x^7+11x^6-2x+10\)
Step-by-step explanation:
To find: \(10x^8+11x^6-2x+5-(8x^8+6x^7-5)\)
Solution:
Like terms refer to terms with same variables and same powers.
Two like terms can be added or subtracted.
Consider the following expression:
\(10x^8+11x^6-2x+5-(8x^8+6x^7-5)=10x^8+11x^6-2x+5-8x^8-6x^7+5\\=(10-8)x^8-6x^7+11x^6-2x+(5+5)\\=2x^8-6x^7+11x^6-2x+10\)

The school store sells highlighters for $1.20 and permanent markers for $1.15. On Monday they sold 8 of these
items earning a total of $9.35. How many of each item did they sell?
Answer:
3 highlighters and 5 permanent markers were sold on Monday.
Step-by-step explanation:
Since the school store sells highlighters for $ 1.20 and permanent markers for $ 1.15, there is a difference between the two products of 5 cents, or $ 0.05.
Therefore, if 8 products were sold for a total of $ 9.35, and since 1.15 x 8 equals 9.20, there is a difference of 15 cents, attributable to the highlighters, since each highlighter costs 5 cents more than the permanent markers .
Therefore, since 15/5 is equal to 3, on Monday 3 highlighters and 5 permanent markers were sold, which is corroborated by the following calculation:
3 x 1.20 = 3.60
5 x 1.15 = 5.75
5.75 + 3.60 = 9.35

on the July 7 billing date, Marvin had a balance due of $216.71 on his credit card. the transactions during the following month were
July 14 office supplies $52.04 July 17 scarf $15.66
July 21 payment of $100
July 24 charge: toy truck $44.03
the interest rate on the card is 1.25% per month. using the previous balance method find the finance charge on August 7 then find the new balance of August 7.
simple interest formula i=prt
Answer:
The first step is to calculate the average daily balance for the billing cycle. This is done by adding up the daily balances for each day of the billing cycle and then dividing by the number of days in the billing cycle. In this case, the billing cycle is from July 7 to August 6, so there are 31 days in the billing cycle.
The daily balances are as follows:
* July 7: $216.71
* July 14: $268.75
* July 17: $284.37
* July 21: $116.71
* July 24: $260.74
The average daily balance is therefore $226.81.
The next step is to calculate the finance charge. This is done by multiplying the average daily balance by the interest rate and then by the number of days in the billing cycle. In this case, the interest rate is 1.25% and the number of days in the billing cycle is 31 days.
The finance charge is therefore $7.43.
The final step is to calculate the new balance. This is done by adding the finance charge to the previous balance. In this case, the previous balance is $216.71 and the finance charge is $7.43. The new balance is therefore $224.14.
Here is the solution in mathematical form:
* Average daily balance = (216.71 + 268.75 + 284.37 + 116.71 + 260.74) / 31 = 226.81
* Finance charge = 226.81 * 0.0125 * 31 = 7.43
* New balance = 216.71 + 7.43 = 224.14

Find the relative rate of change at the given value of . Assume is in years and give your answer as a percent
Answer:
84.37 %.
Step-by-step explanation:
The question is shown in the attached figure.
We have,
\(f(t)=2t^3+10,\ t=3\)
We can find the value of f(t) at t = 3,
\(f(3)=2(3)^3+10\\\\f(3)=64\)
Finding f'(t).
\(f'(t)=6t^2\)
Finding f'(t) at t = 3
\(f'(3)=6(3)^2\\\\=54\)
The relative change is calculated as :
\(\dfrac{f'(t)}{f(t)}=\dfrac{54}{64}\\\\=0.8437\)
In percentage rate of change,
\(\dfrac{f'(t)}{f(t)}=0.8437\times 100\\\\=84.37\%\)
Hence, the required percent change is 84.37 %.

1.What is the core characteristic that defines a zero-based budget?
2.Bianca has take-home pay every month of $800. She anticipates having $675 of expenses in August.
3.In a zero-based budget, why is it important that she put the extra $125 in some budget category?
4.Where might you suggest Bianca budget that extra $125? Why?
5.Does using a zero-based budget mean that your bank account will hit $0 at the end of every month? Explain.
Say that Bianca has take-home pay of $800, she budgets every cent out at the start of the month, and she then she needs less gas money than expected in August. She no longer spends the full $65 she budgeted there. What should she do with the leftover?
Answer:
1. You account for every dollar you make to where your budget shows you have $0
2. She will have $125 leftover to budget out as she sees fit
3. If she does not account for it she may over spend or think she has extra money
4. I would put it in savings
5. No this is not what it means. This means that your paycheck will be able to cover your expenses.
6. You should put extra money in savings. You never know what will occur and savings can always help.
Step-by-step explanation:
Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.
What is the zero-based budget?It is defined as the budgeting method that allows you to fix an amount for everything such as utility expenses, savings, and miscellaneous expenses In other words income minus all expenses plus savings should be equal to zero.
1) The core characteristic of the zero-based budget as follows:
Strategy is dependent on what each unit can provide for the price.Quick changes can be made in the budget anytime if it is required to do so.All the people of the organization can participate in the budgeting process.The purposes of each unit are in line with the corporate aspirations.2) Blanca has take-home pay every month = $800
Total expenses = $675
Savings = Income - Total expenses
= $800 - $675 ⇒ $125
We can assume Blanca has savings of $125 at the end of the month.
3) The extra amount = $800 - $675 ⇒ $125
According to a zero-based budget income minus all expenses plus savings should be equal to zero.
Therefore Blanca needs to allocate this amount($125) to some budget category.
4) Blanca has a total of $675 expenses she will have $125 as saving at the end of the month.
She should allocate this amount to savings because it will increase her wealth.
5) Zero-based budget does not mean that at the end of every month Blanca has zero dollars in her bank account because as per the definition zero-based budgeting means income minus expenses should be equal to zero. Blanca has savings and other emergencies funds in her bank account.
Thus, Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.

Jamie wants a new smart TV/sound system that costs $1,250. He does not have that much in cash to purchase it, so he uses a credit card with 18% annual interest. He puts $250 down, but he only pays the interest each month on that credit card debt. About how much will he pay in interest over 4 years?
Jamie would pay $720 in interest in 4 years
The amount of interest he would have to pay = amount borrowed x interest rate x time
Amount borrowed = cost of the TV - amount put down
$1250 - $250 = $1000
Interest rate = 18%
Time = 4 years
Interest = 1000 x 0.18 x 4 = $720
