The annual rate of interest per year is 8%
Solution:
Given:- Principal (p) = 4600 rupees, Time –Period (t) = 5 years, Total amount(A) = 6440 rupees
First we will calculate the Interest and then using formula of simple interest we will calculate the rate of interest
Interest = Amount – Principal
Interest = 6440 – 4600 = 1840
Now using the formula of simple Interest and on putting values we get,
[tex]\text {Simple Interest }=\frac{P \times R \times T}{100}[/tex]
Where "P" is the principal and "R" is the rate of interest per annum and "T" is the time period
[tex]1840=\frac{4600 \times R \times 5}{100}[/tex]
[tex]\begin{aligned} \mathrm{R} &=\frac{1840 \times 100}{4600 \times 5} \\\\ \mathrm{R} &=\frac{1840}{230} \\\\ \mathrm{R} &=8 \% \end{aligned}[/tex]
Hence, the required rate of interest per year is 8%

1. r closest to 1: figure
2. No linear relationship: Figure 1
3. r equal to 1: Figure 3
Step-by-step explanation:
Correlation is the link between two variables or things"
When one quantity is increasing and the other is also increasing then the correlation co-efficient is positiveWhen one quantity is increasing and the other is decreasing then the correlation is negative.Now for the scatter plot of a correlation:
If the data points are close to a best fit line then the correlation is strongIf the data points follow a linear relationship i.e. a straight line then the correlation is 1 or -1 depending on the sign of correlationIf the data points are more scattered then they have least correlationCorrelation coefficient closest to 1:
We can see in figure 4 that the data points are gathered across a line but not a perfect line and both the quantities are increasing so the correlation coefficient is close to 1.
Least Evidence of linear relationship:
Figure 1 can be observed to conclude that the data points are scattered on whole scatter plot hence creating no relationship
Correlation coefficient equal to -1:
We can see in figure 3 that one quantity is increasing and the other is decreasing and the data points are forming a line so the correlation coefficient will be -1

how can I solve similar trigonometric integrals like this one
Answer:
ln|sec θ + tan θ| + C
Step-by-step explanation:
The integrals of basic trig functions are:
∫ sin θ dθ = -cos θ + C
∫ cos θ dθ = sin θ + C
∫ csc θ dθ = -ln|csc θ + cot θ| + C
∫ sec θ dθ = ln|sec θ + tan θ| + C
∫ tan θ dθ = -ln|cos θ| + C
∫ cot θ dθ = ln|sin θ| + C
The integral of sec θ can be proven by multiplying and dividing by sec θ + tan θ, then using ∫ du/u = ln|u| + C.
∫ sec θ dθ
∫ sec θ (sec θ + tan θ) / (sec θ + tan θ) dθ
∫ (sec² θ + sec θ tan θ) / (sec θ + tan θ) dθ

Write the equation of each line using the given information.
a. The points (2,1.5) and (−5,36.5) both lie on the line.
b. m=4 and the point (3,15) lies on the line.
c. It has the same slope as y=1 and passes through (3,−8).
d.m=2and it has a y-intercept of (0,4).
Answer:
a. 10x + 2y = 23
b. 4x - y + 3 = 0
c. y + 8 = 0
d. 2x - y + 4 = 0
Step-by-step explanation:
a.
Slope of the line 'm' is [tex]\frac{36.5-1.5}{-5-2}[/tex] = [tex]\frac{35}{-7}[/tex] = -5
Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)
⇒y-1.5 = -5·(x-2)
⇒y = -5x + 10 + 1.5
⇒5x + y = 11.5 (or) 10x + 2y = 23
b.
Slope of the line 'm' = 4
Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)
⇒y-15 = 4·(x-3)
⇒y = 4x -12 + 15
⇒4x - y + 3 = 0
c.
Line is parallel to y = 1
Equations of parallel lines only differ by constant. So the required line equation has the form y = c where c is any real number.
But, it is given that the line passes through the point (3,-8)
⇒c=-8
⇒y = -8 (or) y + 8 = 0
d.
Equation of a line with slope 'm' and y-intercept of (0,c) is of the form y = mx + c
⇒y = 2x + 4
⇒2x - y + 4 = 0

The quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\) is \(-\frac{3p^8}{4q^3}\). This is found by dividing the numerical coefficients and subtracting the exponents for variables of the same base (negative exponents indicate reciprocals).
Explanation:To find the quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\), we perform division of the coefficients (15 divided by -20) and subtraction of the exponents for variables with the same base (p's and q's exponents) according to the rules of exponents. First, simplify the numerical coefficients:
\(\frac{15}{-20} = -\frac{3}{4}\)
Now, subtract the exponents for p (applying the formula x^p \cdot x^q = x^{(p+q)}):
\(p^{-4} - p^{-12} = p^{-4 + 12} = p^8\)
Next, apply the same process to the exponents of q:
\(q^{-6} - q^{-3} = q^{-6 + 3} = q^{-3}\)
Combine the results to get the simplified quotient:
\(-\frac{3}{4} × p^8 × q^{-3}\)
Remember that a negative exponent indicates a reciprocal, so we can write \(q^{-3}\) as \(\frac{1}{q^3}\). Therefore, the final answer is:
\(-\frac{3p^8}{4q^3}\)

15. Determine the future value of $4,000 deposited into an ordinary
annuity after each quarter for 3 years at 6% interest compounded
quarterly. (Lesson 5.8)
Answer:
The future value of investment at 6 % compounded quarterly is $ 4782.472
Step-by-step explanation:
Given as :
The principal amount = $ 4000
The rate of interest compounded quarterly = 6 %
The time period = 3 years
Let The future amount = A
From Compounded method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{4\times 100})^{4\times \textrm time}[/tex]
Or, Amount = 4000 × [tex](1+\dfrac{\textrm 6}{4\times 100})^{4\times \textrm 3}[/tex]
Or, Amount = 4000 × [tex](1.015)^{12}[/tex]
Or, Amount = 4000 × 1.195618
∴ Amount = $ 4782.472
Hence The future value of investment at 6 % compounded quarterly is $ 4782.472 Answer
Goran's gas tank is 1/3
full. After he buys 3 gallons of gas, it is 1/2
full. How many gallons can Goran's tank hold?
Answer: 6 gallons
Step-by-step explanation:
1/3 = 2/6. 1/2 = 3/6
2/6 already + 3/6 = 5/6, it
To determine the total capacity of Goran's gas tank, we set up and solved an algebraic equation, finding that the total capacity of the tank is 18 gallons.
The student's question is about figuring out the total capacity of Goran's gas tank based on the information given. To solve this problem, we can set up a simple algebraic equation based on the proportions of the tank's capacity that are filled. Since filling the tank with 3 gallons of gas takes it from being 1/3 full to 1/2 full, we know that these 3 gallons represent the difference between 1/3 and 1/2 of the tank's total capacity.
Let's denote the total capacity of the tank as 'T' gallons. According to the question:
1/3 of 'T' + 3 gallons = 1/2 of 'T'We can now set up the equation:
1/3 * T + 3 = 1/2 * T
To find 'T', we need to solve for T:
1/2 * T - 1/3 * T = 3
This simplifies to:
(3T - 2T) / 6 = 3
T/6 = 3
Now multiply both sides by 6 to solve for T:
T = 18
Therefore, the total capacity of Goran's gas tank is 18 gallons.
the local bakery uses 1.75 cups of flour in each batch of cookies. the bakery usee 5.25 cups of flour this morning. How many batches of cookies did the bakery make? if there are 5 dozon cookies in each batch, how many cookies did the bakery make?
The bakery made 3 batches of cookies and a total of 180 cookies.
To determine the number of batches of cookies the bakery made, we divide the total amount of flour used by the amount of flour used in each batch. The bakery used 5.25 cups of flour in total, and each batch requires 1.75 cups of flour. Therefore, the number of batches made is:
[tex]\[ \text{Number of batches} = \frac{\text{Total flour used}}{\text{Flour per batch}} = \frac{5.25}{1.75} \][/tex]
[tex]\[ \text{Number of batches} = 3 \][/tex]
Since there are 5 dozen cookies in each batch, we multiply the number of batches by the number of cookies per batch to find the total number of cookies made:
[tex]\[ \text{Total number of cookies} = \text{Number of batches} \times \text{Cookies per batch} \][/tex]
[tex]\[ \text{Total number of cookies} = 3 \times (5 \times 12) \][/tex]
[tex]\[ \text{Total number of cookies} = 3 \times 60 \][/tex]
[tex]\[ \text{Total number of cookies} = 180 \][/tex]
Thus, the bakery made 3 batches of cookies, resulting in a total of 180 cookies."

14. You start an investment account with $3000 and save $100 each month. Write a
rule to represent the total amount of money you invest into your account as an
arithmetic sequence. How much money will you have invested after 12 months?
Answer:
4200
Step-by-step explanation:
In an arithmetic sequence equation t=a + (n-1)d, a is the starting value. In this case, a=3000.
Although, since the initial investment is not considered the first month, the equation is t = a + dn.
d is the rate of change. In this case, the rate of change is 100 for every month, n.
Substitute these values from the problem to get an equation:
t = 3000 + 100n
t means the total amount of money we have for the amount of months (n) that passed.
Sub n for 12.
t = 3000 + 100n
t = 3000 + 100(12)
t = 4200
You will have $4200 after 12 months of investment.
