Answer:
-8n² - 8n + 3
Step-by-step explanation:
Combine like terms (terms with the same variables, as well as the same amount of that variable).
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)
First, distribute the negative sign to all terms within the second parenthesis:
4n⁴ - 8n + 4 - 8n² - 4n⁴ - 1
Combine like terms:
(4n⁴ - 4n⁴) - 8n² - 8n + (4 - 1)
-8n² - 8n + 3
-8n² - 8n + 3 is your answer.

Michael starts a website for people in his town to share news and photos. Before launching the website, he has his friends and family sign up. Then, he uses the equation shown to estimate the number of users, y, who will have signed up x weeks after he officially launches the website.
y = 82(1.045)x
part A: What is the rate of growth Michael expects each week after launching the website?
A.
104.5%
B.
95.5%
C.
0.045%
D.
4.5%
Answer:
D. 4.5%
Step-by-step explanation:
Michael expects the rate of growth to be 4.5% each week because in the equation inside the parenthesis is 1.045 meaning it has already had 1 added to the original percentage so subtract 1 from 1.045 then move the decimal twice to the right and change it into a percentage sight which will give you 4.5%
the growth rate per week is 4.5% Micheal can expect.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
The given equation is,
y = 82(1.045)x,
Where y represents number of people and x represent number of week.
After 1 week, x=1
y=82×1.045
The multiplying factor is 1.045
It implies that after 1 week growth increase by, 0.045
The percentage value of 0.045 is 4.5%
So the growth rate per week is 4.5%.

What kind of fraction will you have when the percent is over 100%
Answer:
100% means “100 out of 100” — in other words, everything. So when you say you have 100% confidence in someone, you mean that you have complete confidence in them. But a lot of times, percentages larger than 100% are perfectly reasonable.!
Answer:
"Improper Fraction"
Step-by-step explanation:
An improper fraction is a fraction where the numerator exceeds the denominator. When the percent is over 100%, then technically the numerator is exceeding the denominator when the percentage is converted to a fraction.
Example:
110%convert to fraction... [tex]\frac{110}{100}[/tex]simplify... [tex]\frac{11}{10}[/tex]You can go further by making it a proper fraction but that is beyond the current problem we are solving.

Aleksandra started studying how the number of branches on her tree grows over time. Every 1.51.51, point, 5 years, the number of branches increases by an addition of \dfrac{2}{7} 7 2 start fraction, 2, divided by, 7, end fraction of the total number of branches. The number of branches can be modeled by a function, NNN, which depends on the amount of time, ttt (in years). When Aleksandra began the study, her tree had 525252 branches. Write a function that models the number of branches ttt years since Aleksandra began studying her tree. N(t) =N(t)=N, left parenthesis, t, right parenthesis, equals
Answer:
52(9/7)^t/1.5
Step-by-step explanation:
The function N(t) a which models the number of branches t years after Aleksandra began studying her trees ;
Initial number of branches = 52
Increment every 1.5 years = 2/7
N(t) = Initial * (1 + r)^t
t expressed per year = t/1.5
Hence,
N(t) = 52(1 + 2/7)^t/1.5
N(t) = 52(9/7)^t/1.5

Calculate simple interest :
a) P = 2500, rate 8% PA, T = 1 year
b) P = 4200, rate 6% P.A, T = 3 year
Nhen 6 added to a number gives 13
Answer:
the simple interest in both cases is 200 and 756 respectively
Step-by-step explanation:
The computation of the simple interest is shown below:
As we know that
Simple interest = P × r% × t
So
a. Simple interest is
= 2,500 × 8% × 1
= 200
b. The simple interest is
= 4,200 × 6% × 3
= 756
Hence, the simple interest in both cases is 200 and 756 respectively

Answer:
C 12.50b+22.50n≥800
Step-by-step explanation:
Tonya is staring a jewelry business. She is going to sell b bracelets for $12.50 each and n necklaces for $22.50. Tonya wants to make at least $800 a month.
When we use the word at least in Mathematics is means that it is equal to or more than $800.
It is represented by the symbol ≥
Number of bracelets = b
Number of necklaces = n
Therefore, the inequality below models this situation is given as:
$12.50 × b + $22.50 × n ≥ $800
= 12.50b + 22.50n ≥ 800
