year's
this year´s profit is $ 472857
Explanation
we can easily solve this by using a rule of three
so
Step 1
a)let x represents this year's profit
so
if it is decreases by 2.1 %
[tex]\begin{gathered} x=100-2.1\text{ = 97}.9 \\ x=97.9\text{\%} \end{gathered}[/tex]so, this year's profit is 97.9% of the last year profit
hence
[tex]\begin{gathered} \text{if} \\ 483000\rightarrow100\text{ \%} \\ x\rightarrow97.9\text{ \%} \end{gathered}[/tex]we can make a proportion
[tex]\frac{483000}{100}=\frac{x}{79}[/tex]finally, solve for x,
[tex]\begin{gathered} \frac{483000}{100}=\frac{x}{97.9} \\ \text{Multiply both sides by 9}7.9 \\ \frac{483000}{100}\cdot97.9=\frac{x}{97.7}\cdot97.9 \\ 472857=x \end{gathered}[/tex]therefore
this year´s profit is $ 472857

The formula that can be used to find the nth term of the sequence is aₙ = 4n + 1
How to find the formula of an arithmetic sequence?The sequence follows an arithmetic patterns. Therefore, the formula for arithmetic progression can be used to find the nth term as follows:
aₙ = a + (n - 1)d
where
n = number of termsd = common differencea = first termTherefore, using the sequence 5, 9, 13, 17, 21
a = 5
d = 9 - 5 = 4
Hence,
aₙ = 5 + (n - 1)4
aₙ = 5 + 4n -4
aₙ = 5 - 4 + 4n
Therefore,
aₙ = 4n + 1

A customer at a shipping store is planning to send a package and is considering two options. The customer can send a package for $3, plus an additional $2 per pound. The cost, y, can be represented by the equation y = 3 + 2x, where x represents the amount of pounds of the package. Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
Based on the graph of the system of equations, when will the cost of the two shipping options be the same?
A package that weighs 10 pounds will cost $17 for both options.
A package that weighs 7 pounds will cost $17 for both options.
A package that weighs 17 pounds will cost $31 for both options.
A package that weighs 17pounds will cost $37 for both options.
The correct option is :
A package that weighs 7 pounds will cost $17 for both options.
What is an equation ?The declaration that shows that the provided variables exist is a mathematical equation. When describing the scenario in this circumstance, two or more factors are taken into account.
The equation can be used to symbolize the price, y: Y is equal to 3 plus 2 times the weight of the package, x.
Another choice is for the buyer to pay a one-time price of $17, which is represented by the equation y = 17, in order to send the package.
We'll compare the equation as a whole.
In this case,
3 + 2x = 17

Step-by-step explanation:
It is possible for 2 lines to
intersect in such a way
that 3 of the angles
formed have measures 20,
70, and 20.?
Sometimes true,
Never true,
Always true.
Answer:
sometimes true
Step-by-step explanation:
Given, two straight lines intersect each other in such a way that one of the angles formed measure 90°.
We know that, lines which intersect to form a right angle are known as perpendicular lines
In the above figure , AB is perpendicular to CD
Considering ∠AOC=90°
Now,
∠AOC+∠AOD=180° [Linear pair]
90°+∠AOD=180°
∠AOD=90°
Similarly,
∠AOC+∠BOC=180° and ∠BOD+∠AOD=180° [Both making linear pair]
So, we get ∠BOC=90° and ∠BOD=90°
Hence, ∠AOC=∠AOD=∠BOC=∠BOD=90°

What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
Given f(x)= -4x-2
g(x)=2x²+4x-5
For (f-g)(x) = -4x-2+2x²+4x-5
=2x²-9
(f-g)(x) = 2x²-9
