In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed). It is not the same as a fee that the borrower might pay to the lender or another entity. Interest advance, but rather on a pro-rata basis as a share of the reward received by risk-taking business people when revenue is earned that exceeds all costs.
For Interest, a customer who borrows money from a bank typically pays interest on it, so they pay the bank more than they borrowed; likewise, a customer who earns interest on their savings may withdraw more than they originally put. When it comes to savings, the bank serves as the borrower while the consumer serves as the lender.

Hence , the instantaneous rate of change of f(x) = e^(2x)e^(7x) at x = -1 will be 9e⁻⁹ .
The fast rate of modification is that the modification within the rate at a specific instant, and it's same because the modification within the by-product worth at a selected purpose. For a graph, the fast rate of modification at a selected purpose is that the same because the tangent line slope.Instantaneous rate of modification of a perform is portrayed by the slope of the road, it tells you by what quantity the perform is increasing or decreasing because the x -values modification.We have given a function f(x) = e²ˣ e⁷ˣ.
You can realize the fast rate of modification of a perform at a degree by finding the by-product of that perform and plugging within the x-value of the purpose.
On simplifying , we can write f(x) as e⁹ˣ
Differentiating f(x) with respect to x , we get
f'(x) = d/dx (e⁹ˣ)
f'(x) = e⁹ˣ × 9
Putting x = - 1 in f'(x) , we get
f'(-1) = 9e⁹⁽⁻¹⁾

Larry Mitchell invested part of his $19,000 advance at 3% annual simple interest and the rest at 2% annual simple interest. If his total yearly interest from both accounts was $560, find the amount invested at each rate.
Larry Mitchell invested $7600 at 3% rate of interest and $11400 at 2% rate of interest.
In the field of finance, interest is the payment of a sum over and above the principal amount owed by a lender or depositor to a borrower or deposit-taking financial institution at a set rate.
Rate of an interest in defined as the amount that a lender charges a borrower in interest as a percentage of the principal.
Larry invested part of his $19000 at 3% and the rest at 2%
Let he invested $'x' at 3% interest .
Therefore amount invested at 2%=$(19000-x)
Interest earned annually at 3% on $x = [tex]\frac{3}{100} \times x =0.03x[/tex] .
Interest earned annually at 2% on $(19000-x)=[tex]\frac{2}{100} \times(19000-x)[/tex]
=[tex]380-0.02x[/tex]
Now the combined interest for both the investment is $560 .
Therefore we can form a linear equation to solve for x:
0.03x+380-0.02x=560
or, 0.01x=180
or, x=18000
Therefore Larry invested $18000 at 3% interest.
Money invested at 2%=$(19000-18000)=$1000
Hence Larry invested $18000 at 3% rate of interest and $1000 at 2% rate of interest.

In mathematics, the greater than sign is a basic mathematical notation used to represent an inequality between two values. The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle. A typical use of the greater than sign is to compare two values, where the first is greater than the second, or one is greater than the other. The greater than sign is an approximation of a closing square bracket.Maximum width of the wall hanging can be 3.75 feet and maximum height can be 6.5 feet.
After completing the work it was found that the width measures 3 3/5 feet and height was 3 3/4 tall.

This part of the wall is 5 metres long and 1.5 metres high.
The complete wall will be 8 metres long and 1.5 metres high.
How many more bricks does Jack need to complete the wall?
The amount of bricks that Jack would need to complete the wall is 180.
How many more bricks does he need?The first step is to determine the total amount of bricks he would need to build the wall. In order to determine this value, ratio analysis would be used.
Total bricks needed = (area of wall x number of blocks already used) / (area of wall already built)
Area of wall = 8 x 1.5 = 12
Area of wall already built = 5 x 1.5 = 7.5
Total bricks needed = (12 x 300) / 7.5 = 400 bricks
Number of bricks needed to complete the wall = 400 - 300 = 180 bricks

How to find the number using variable?The difference of a number and eight is tripled, then the result is six more than the number.
Therefore, the number will be represented by a variable
let the number = x
Hence,
3(x - 8) = x + 6
Therefore, let's open the bracket
3(x - 8) = x + 6
3x - 24 = x + 6
subtract x from both sides of the equation
3x - 24 = x + 6
3x - x - 24 = x - x + 6
2x - 24 = 6
add 24 to both sides of the equation
2x - 24 + 24 = 6 + 24
2x = 30
divide both sides by 2
x = 30 / 2

what is the values of a and b
After evaluation we get the values as a = 8 + -0.4285714286b
Given, the expression is (7a ₊ 10)/(3b ₊ 6) = 72
Simplifying
(7a ₊ 10) ₊ (3b ₊ 6) = 72
Reorder the terms:
(10 ₊ 7a) ₊ (3b ₊ 6) = 72
Remove parenthesis around (10 ₊ 7a)
10 ₊ 7a ₊ (3b ₊ 6) = 72
Reorder the terms:
10 + 7a + (6 + 3b) = 72
Remove parenthesis around (6 + 3b)
10 + 7a + 6 + 3b = 72
Reorder the terms:
10 + 6 + 7a + 3b = 72
Combine like terms: 10 + 6 = 16
16 + 7a + 3b = 72
Solving
16 + 7a + 3b = 72
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + 7a + -16 + 3b = 72 + -16
Reorder the terms:
16 + -16 + 7a + 3b = 72 + -16
Combine like terms: 16 + -16 = 0
0 + 7a + 3b = 72 + -16
7a + 3b = 72 + -16
Combine like terms: 72 + -16 = 56
7a + 3b = 56
Add '-3b' to each side of the equation.
7a + 3b + -3b = 56 + -3b
Combine like terms: 3b + -3b = 0
7a + 0 = 56 + -3b
7a = 56 + -3b
Divide each side by '7'.
a = 8 + -0.4285714286b

Using integrals, we have that:
a) The mean is of 1205 and the standard deviation is of 2.87.
b) P(1200 < X < 1202) = 0.2.
What is the probability distribution?The distribution is given by:
f(x) = 0.1, 1200 < x < 1210.
The integral of this function will be used to find the probabilities.
The mean of the distribution is given by:
[tex]\mu = \int_{1200}^{1210} xf(x) dx[/tex]
Hence:
[tex]\mu = \int_{1200}^{1210} 0.1x dx [/tex]
[tex]\mu = 0.05x^2|_{x = 1200}^{x = 1210}[/tex]
Hence the mean is:
0.05(1210² - 1200²) = 1205.
The variance of the distribution is given by:
[tex]\sigma^2 = \int_{1200}^{1210} (x - \mu)^2 f(x) dx[/tex]
Hence:
[tex]\sigma^2 = \int_{1200}^{1210} 0.1(x - 1205)^2 dx[/tex]
[tex]\sigma^2 = 0.033(x - 1205)^3|_{x = 1200}^{x = 1210}[/tex]
[tex]\sigma^2 = 0.033(1210 - 1205)^3 - 0.033(1200 - 1205)^3[/tex]
[tex]\sigma^2 = 8.25[/tex]
The standard deviation is the square root of the variance, hence:
[tex]\sigma = \sqrt{8.25} = 2.87[/tex]
For item b, the probability is given by:
[tex]P(1196 < X < 1202) = \int_{1200}^{1202} 0.1 dx[/tex]
P(1196 < X < 1202) = 0.1x, from x = 1200 to x = 1202.
Applying the Fundamental Theorem of Calculus:
0.1(1202) - 0.1(1200) = 0.2.
The lower bound is of 1200 because the distribution is not defined for values less than 1200.
Hence:
P(1200 < X < 1202) = 0.2.

if you were to plot a graph of the profit generated by the book, what would the slope and y intercept represent?
The slope of the graph is 20 and the y-intercept is -1050.
The slope of a linear graph is defined as the gradient of the graph .It is also defined by trigonometric properties as the tangent of the angle formed by the line with the positive y-axis.
The y-intercept is the point of intersection of the graph and the y-axis.
The general equation of a straight line in the cartesian plane is given by
y = m x + c where 'm' represents the slope and 'c' represents the y-intercept.
It is given that the one time editing cost is 1050 dollars.
Variable cost of printing each book = 15 dollars
Each book is sold at = 35 dollars
∴profit per book sold = 35 - 15 = 20 dollars
Let Gary sells x number of books . Profit from selling x books = 20 x
Let us consider the net profit of Gary after selling x books be represented by y.
∴ y = profit from x books - establishment cost
or, y = 20 x -1050
Now comparing the above equation with the general equation of a straight line( y = mx + c ) we can infer that:
slope(m) = 20
y-intercept (c) = -1050

B. -5/9
C. 17.47
D. 4.28192489...

Step-by-step explanation:
Irrational numbers are those which cannot be expressed by the ratio of two integers.
A is rational because it is a recurring decimal. Recurring decimals can be represented by the ratio of two integers (this one can be represented by the fraction -2752/333, which is a ratio of two integers).
B is a fraction with two integers, therefore it is rational. -5/9 is a ratio of two integers.
C can be represented by 1747/100.
D is an infinite decimal but isn't recurring like A, meaning it cannot be represented by the ratio of two integers, and is therefore it is irrational, unless you are shown further digits of the decimal which prove it to be recurring, which is not the case here.
