The finance charge on Daniyar's May statement is $4.45.
What is finance charge?
The cost of consumer credit expressed as a dollar amount is the financing charge. It includes any fee imposed by the creditor as an incident to or a requirement of the credit extension that is directly or indirectly payable by the customer. It excludes any fee that would be paid in an equivalent cash transaction.
The finance charge is equal to the product of the average daily balance and the monthly periodic rate.
So,
$270.31 x 1.65%
= $270.31 x 0.0165
= $4.45

Answer:
[tex]f(x) = $\begin{cases}3x-4 & -2\le x < 1\\x + 3 & 1 \le x \le 5\\8 & 5 \le x \le 8 \end{cases}$[/tex]
Step-by-step explanation:
The permissible values of x for a function is called the domain of the function. Permissible values mean that the function is real and defined.
The range of a function is the set of all y values for the domain
If a point on a graph is a filled circle, that point is included in the domain(x-value) and represents a ≤ or a ≥ inequality
If a point on a graph is an unfilled or hollow circle, that point is not included in the domain(x-value) and represents a < or a >inequality
Let's look at the three parts of the given piecewise graph
Piecewise part A
We see that the minimum and maximum values of x for this function are x = -2 and x = 1 respectively. The point corresponding to x= 1 is a hollow circle so it is not included in the domain whereas the point corresponding to x = -2 is included
Let's find the equation of this line:
Take 2 points on the line. We choose points (0, -4) and (1, -1)
Slope of this line is -1 -(-4)/(1-0) = (-1 + 4)/1 = 3
The y-intercept is -4
So equation of the line is y = 3x -4 for -2 ≤ x < 1
Proceeding in a similar manner we can determine the domain and function equation for the other two pieces, B and C
Piecewise part B
Domain of x : 1 ≤ x ≤5
Slope = (8-4)/(5-1) = 4/4 = 1
Equation is of the form y = 1x + b
To calculate b, plug in values of x = 1, y = 4 to get
4 = 1(1) + b
b = 3
Equation of this piecewise function is
y = x + 3 for 1 ≤ x ≤ 5
Piecewise Part C
This is a flat horizontal line at y = 8
So that is the equation of the line
The domain of this piece is 5 ≤ x ≤ 8
So we get y = 8 for [tex]$\begin{cases}3x-4 & -2\le x < 1\\x + 3 & 1 \le x \le 5\\8 & 5 \le x \le 8 \end{cases}$[/tex]
Normally, instead of using y we use f(x)
Putting all this together we get the piecewise function defined as
[tex]f(x) = $\begin{cases}3x-4 & -2\le x < 1\\x + 3 & 1 \le x \le 5\\8 & 5 \le x \le 8 \end{cases}$[/tex]
Find LM tangent angle circle
Applying the two-tangent theorem, the length of LM is: A. 18.
What is the Two-Tangent Theorem?The two-tangent theorem states that if two tangents are drawn from a circle to meet at a point outside the circle, then the tangent segments are congruent to each other, that is they have equal lengths.
Segments LK and LM are tangent segments drawn to meet at the external point L. This means, the length of Lk and the length of LM would be equal to each other.
LK = 4x - 2
LM = 3x + 3
LK = LM
Substitute
4x - 2 = 3x + 3
Combine like terms
4x - 3x = 2 + 3
x = 5
LM = 3x + 3
Plug in the value of x
LM = 3(5) + 3
LM = 15 + 3
LM = 18

Carlos builds a robot that moves with small wheels. each wheel has six 5 inch long metal spokes that meet in the center what is the length of the arc
Answer:
Explanation:
a)
The formula for calculating the length of an arc is expressed as
Length of arc = θ/360 x 2πr
where
θ is the angle subtended at the center of the circle.
r is the radius of the circle
From the information given,
diameter = 5(length of each metal spoke)
r =diameter/2 = 5/2 = 2.5
Recall, the total angle in the circle is 360 degrees. There are 8 partitions. Angle between consecutive spokes is
360/8 = 45. Thus,
θ = 45
Length of are between consecutive spokes = 45//360 x 2 x π x 2.5
Length of are between consecutive spokes = 5π/8
b) The formula for calculating the area of a sector is expressed as
area of a sector = θ/360 x πr^2
By substituting the values,
area of a sector = 45/360 x π x 2.5^2
Area of sector = 25π/32 square inches
Write the domain and range of g as intervals or unions of intervals
It's important to know that empty circles refer to open intervals or parenthesis.

what is the arc measure of ct in radians? what is the arc length in feet?
We will determine the arch lenght (In radians) as follows:
*First: We transform the measure of the angle from degrees to radians, that is:
[tex]\theta=80\cdot\frac{\pi}{180}\Rightarrow\theta=\frac{4\pi}{9}[/tex]*Second: We find the arc length:
[tex]s=r\theta\Rightarrow s=(13.2)(\frac{4\pi}{9})[/tex][tex]\Rightarrow s=\frac{88}{15}\pi[/tex]So, the arc length for CT is 88pi/15 radians.
*Third: We find its measure in feet:
[tex]s\approx18.43[/tex]So, the arch length for CT in feet is approximately 18.43 feet.
A price-taking firm makes air conditioners. The market price of one of its new air conditioners is $125. The firms total cost information is given in the table below

2. To maximize profits, the price-taking firm should produce 6 air conditioners per day.
What is the profit-maximizing point?The profit-maximizing point or units is the output and price interaction that ensures that the marginal revenue equals the marginal cost.
The marginal revenue (MR) is the revenue earned from an additional unit. The marginal cost (MC) is the production cost per additional unit.
For price-taking firms, the maximum profit is achieved at the level of output where MC equals MR.
Market Price for one unit = $125

Tom invested $2500 a year in a mutual fund for 15 years. If the market value of the fund increases 5% per year, what will be the value of the fund after 15 deposits?
The value of the mutual fund of Tom after 15 deposits will be $5197.320 .
In the question ,
it is given that , Tom invested $2500 in mutual fund for 15 years ,
So,
the investment amount(P) = $2500 .
time for investment(x) = 15 years
rate of increase(r) = 5% = 0.05
The amount of fund after 15 deposits can be calculated using the formula
amount = P*(1+r)ˣ
Substituting the values of P, x and r , we get
amount = 2500*(1 + 0.05)¹⁵
= 2500*(1.05)¹⁵
= 5197.320
Therefore , The value of the mutual fund of Tom after 15 deposits will be $5197.320 .
