Apparently, your periodic rate is that used to compute the interest accrued each period. It seems to be the compound (annual) rate divided by the number of periods in a year: quarterly, 4; monthly, 12; daily, 365; biweekly, 26; semimonthly, 24.
_____
If you want the effective annual rate to be 18% in each case, the numbers are different. For n periods per year, those are calculated as
[tex]\sqrt[n]{1.18}-1[/tex]
A periodic rate of 0.04224664 will give an effective annual rate of 18%.
Periodic rates for a 18% compound rate compounded quarterly, monthly, daily, biweekly, and semimonthly are calculated as follows :
Quarterly periodic rate: 0.18/4 = 0.045 or 4.5%Monthly periodic rate: 0.18/12 = 0.015 or 1.5%Daily periodic rate: 0.18/365 ≈ 0.000493 or 0.0493%Biweekly periodic rate: 0.18/26 ≈ 0.006923 or 0.6923%Semimonthly periodic rate: 0.18/24 ≈ 0.0075 or 0.75%Q #5 please I need your help

The drama club is washing cars for a fundraiser if the rate continues how many cars will they wash in 4 hours
In order to calculate the number of cars the drama club could wash in 4 hours, one needs to know their washing rate per hour. Supposing it to be 2 cars/hour, the multiplication of the rate by the number of hours (2 * 4), shows that they could wash 8 cars.
Explanation:The subject of this question is mathematics, specifically rate problems in the context of a real-world situation. In order to solve a problem like this, we need to know the rate at which the drama club is washing cars. This information is missing from the question, so let's suppose that they wash 2 cars per hour. In that case, their rate of washing cars is 2 cars/hour. Then, if you want to find out how many cars they could wash in 4 hours if they continue at this pace, you'll need to multiply their rate by the number of hours.
Let's calculate: Rate (2 cars/hour) * Time (4 hours) = 8 cars.
This means that if they keep washing cars at a rate of 2 cars per hour, they will have washed 8 cars in 4 hours.

if i have a pay rate of $21.00 and marked up 78.7% and made a 10% profit. how did i get $41.28?
Step-by-step explanation:
Since we have given that
Amount of pay rate =$21
If she marked up by 78.7% , so it becomes
[tex]78.7\%\text{ of}\$21\\\\=\frac{78.7}{100}\times \$21\\\\=\$16.527[/tex]
So, our amount for pay rate becomes
[tex]21+16.527\\\\=\$37.527[/tex]
Now, he said he made a profit of 10%,so it becomes
[tex]10\%\text{ of }37.527\\\\=\frac{10}{100}\times 32.527\\\\=\$3.7527[/tex]
So, our new pay rate becomes
[tex]37.527+3.7527\\\\=\$41.2797[/tex]
This is the step through which we can get $41.28.

The number of visitors was about 15,051 after ______ weekends.
Answer:
1) There were 18582 visitors on the opening weekend.
2) There were approximately 7199 visitors on the 9th weekend.
3) The number of visitors was about 15,051 after 2 weekends.
Step-by-step explanation:
Given : The curve of best fit to model the data is given below.
[tex]y=18582(0.90)^x[/tex]
To find : Complete the statements,
1) There were _____ visitors on the opening weekend.
2) There were approximately _____ visitors on the 9th weekend.
3) The number of visitors was about 15,051 after ______ weekends.
Solution :
[tex]y=18582(0.90)^x[/tex] is the exponential equation:
where, y is the number of visitors and x are the weekends since opening
1. Since the opening weekend is the day of the the park's opening.
So, replace x=0 in our exponential equation to get the number of visitors on the opening weekend:
[tex]y=18582(0.90)^x\\y=18582(0.90)^0\\y=18582(1)\\y=18582[/tex]
Therefore, There were 18582 visitors on the opening weekend.
2. To find the approximate number of visitors on the ninth weekend.
We replace x=9 in our exponential equation:
[tex]y=18582(0.90)^x\\y=18582(0.90)^9\\y=7199.0475[/tex]
Rounded to the nearest integer : y=7199
Therefore, There were approximately 7199 visitors on the 9th weekend.
3. Here, we know that the number of visitors is 15051
Since y represents the number of visitors.
So, replace y=15051 in our exponential equation and solve for x:
[tex]y=18582(0.90)^x\\\\15051=18582(0.90)^x\\\\ \frac{15051}{18582} =0.90^x\\\\0.90^x= \frac{5017}{6194} \\\\ln(0.90^x)=ln(\frac{5017}{6194})\\\\xln(0.90)=ln(\frac{5017}{6194})\\\\x= \frac{ln(\frac{5017}{6194})}{ln(0.90)} \\\\x=2.0002[/tex]
Rounded to the nearest whole number : x=2
Therefore, The number of visitors was about 15,051 after 2 weekends.
Can someone graph x < 2?
To graph x < 2, draw a number line with an open circle at 2, and shade to the left of the circle. This indicates all numbers less than 2 are included, while 2 itself is not.
Explanation:To graph the inequality x < 2, you first need to draw a number line. Let's represent x by a point on the number line. The inequality x < 2 means that x can be any value less than 2, but not 2 itself.
To represent this on the number line, you would place an open circle (which represents exclusion) at 2, and then shade or draw an arrow pointing to the left (representing all numbers less than 2). This visually shows that the solution contains all numbers less than 2, but not 2 itself.

The solutions for the equation 2x^2 + 9x + 8 = 0 are x = (-9 + √17)/(4) and x = (-9 - √17)/(4), which are approximately 0.44 and -4.94, respectively.
Explanation:To solve the equation 2x^2 + 9x + 8 = 0, we can use the quadratic formula. The quadratic formula states that the solutions for any quadratic equation of the form ax^2 + bx + c = 0 can be calculated using the formula:
x = (-b ± √(b^2 - 4ac))/(2a)
For the given equation, a = 2, b = 9, and c = 8.
Plugging these values into the formula, we get:
x = (-9 ± √(9^2 - 4*2*8))/(2*2)
Simplifying, we have:
x = (-9 ± √(81 - 64))/(4)
x = (-9 ± √17)/(4)
So, the solutions for the equation 2x^2 + 9x + 8 = 0 are x = (-9 + √17)/(4) and x = (-9 - √17)/(4), which are approximately 0.44 and -4.94, respectively.

what is the y-intercept of (2, 18) and (6, 6)?
Assuming you want the y-intercept of the line through those two points, you can find it a couple of different ways.
The slope of the line is ...
... slope = (change in y)/(change in x) = (6-18)/(6-2) = -12/4 = -3
We are given the y-value for x=2. When x decreases by 2 to x=0, then the y-value changes by (-2)·(-3) = +6, from 18 to 24.
___
You can also write the equation of the line in point-slope form as ...
... y = -3(x -2) +18
Again, when x=0, the y-intercept is ...
... y = -3(0 -2) +18 = 6 +18 = 24

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 0 ) and (x₂, y₂ ) = (0, - 5 )
m = [tex]\frac{-5-0}{0-3}[/tex] = [tex]\frac{5}{3}[/tex]

The Answer is 335.
To evaluate the expression {362-[6×3+(48÷2)×2]}+3(9+4), we need to follow the order of operations. After simplifying each part of the expression and performing the necessary operations, the final result is 287.
Explanation:To evaluate the expression {362-[6×3+(48÷2)×2]}+3(9+4), we need to follow the order of operations, also known as PEMDAS. This acronym stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, let's simplify the expression inside the parentheses: [6×3+(48÷2)×2].
Using the division rule, we have: [6×3+(24)×2].Next, we perform the multiplications: [18+48×2].Then, we simplify further: [18+96].The sum inside the parentheses is equal to 114. Therefore, the expression becomes {362-114}+3(9+4).Next, let's evaluate the expression inside the curly braces: {362-114}. This can be done by subtracting 114 from 362, resulting in 248.Finally, we have to evaluate the expression 3(9+4). Following the order of operations, we perform the addition inside the parentheses first: 3(13). Multiplying 3 by 13 gives us 39.Now, we add the results of the two evaluated expressions: 248+39. This gives us a final result of 287.

Find the equation of the line in slope-intercept form.Slope is 2/3 through (3, 4)
Remark
You have been told that the slope of the line is 2/3. That means that if the general equation is y = mx + b is the equation for the slope intercept formula and since m = the slope, then m also equals 2/3
y = (2/3)x + b
Use the point to find b
when x = 3
y = 4 This comes from the point
4 = (2/3) * 3 + b multiply 2/3 and 3 together
4 = 6/3 + b Simplify 6/3
4 = 2 + b Subtract 2 from both sides
4 - 2 = b Combine
2 = b
Equation
y = (2/3)x + 2
