The rate of interest for simple compounding if Louis is offered an interest rate of 6.35% for an investment with continuous compounding, is 0.0656 or 6.56%, so option D is correct.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
Louis is offered an interest rate of 6.35% for an investment with continuous compounding,
Here, P will be the same, the amount will be the same and the time period will be the same then,
The amount in simple compounding = The amount in continuous compounding
[tex]P(1 + r)^t = Pe^{rt}[/tex]
Here, r is the rate of interest for simple compounding,
[tex]1 + r = e^{0.0635}[/tex] (All same quantities get canceled)
r = 1.0656 - 1

a conditional probability p(b|a) is equal to its marginal probability p(b) if
A conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.
The likelihood that any two events will occur is equal to the sum of the probabilities of each event separately, less the probability that the two occurrences will meet. However, if two occurrences are incompatible with one another, then there is a zero probability of the two events intersecting, therefore the likelihood that either one or the other will occur is equal to the sum of the two individual probabilities.
To calculate conditional probability, use the following formula:
p( b | a ) = p( a ∩ b )/ p(a)
It is known that if two events A and B are independent, then p(a ∩ b) = p (a) . p(b)
So, p(b | a) = [p (a) . p(b)]/p(a) = p(b)
Thus, it is concluded that a conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

Rationalise the denominator 1/5-root 2
Answer:
the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).
Step-by-step explanation:
Correctly me if im wrong. To rationalize the denominator of the fraction 1/(5^(1/2)-2), we can use the conjugate of the denominator. The conjugate of a+b is a-b, so the conjugate of 5^(1/2)-2 is 5^(1/2)+2. We can then multiply the numerator and denominator of the fraction by the conjugate to obtain:
1/(5^(1/2)-2) * (5^(1/2)+2)/(5^(1/2)+2)
= (1*(5^(1/2)+2)) / ((5^(1/2)-2)*(5^(1/2)+2))
= (5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)
Notice that we can further simplify this expression by substituting 5^(1/2) with x and expanding the denominator:
(5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)
= (x+2) / (x^2 - 2x - 4)
= (x+2) / (x-2)(x+2)
The denominator of this expression can be further simplified by factoring out x-2, which gives us:
(x+2) / (x-2)(x+2)
= (x+2) / (x-2)(x-2 + 4)
= (x+2) / (x-2)(x^2 - 2x + 4 - 4)
= (x+2) / (x-2)(x^2 - 2x)
= (x+2) / (x-2)((x-1)(x+1))
Finally, we can use the fact that x-1 and x+1 are factors of x^2-2x, which means that we can factor out x-1 and x+1 from the denominator to obtain the fully simplified expression:
(x+2) / (x-2)(x^2 - 2x)
= (x+2) / (x-2)(x-1)(x+1)
= (x+2) / ((x-2)(x-1)(x+1))
Therefore, the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).

The coordinates of points a and b are a(2, 16) and b(22, 4). what are the coordinates of the point that is 34 of the way from a to b?
The coordinates of the point is (17, 7)
How to determine the coordinates of the point?From the question, we have the following parameters that can be used in our computation:
Point A = (2, 16)
Point B = (22, 4)
Ratio = 3/4
The ratio can be expressed as
m : n = 3 : 1
The coordinates of the point can be calculated as
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
Substitute the known values in the above equation, so, we have the following representation
Point = 1/(3 + 1) * (3 * 22 + 1 * 2, 3 * 4 + 1 * 16)

Two stores have the same item for the same price. • Store A offers successive discounts of 5% one week, 10% the next week, and 10% the third week. • Store B offers one discount of 25% the third week. Which offer results in the greater discount? Justify your answer. Show your work.
Answer:
Below
Step-by-step explanation:
10 % OFF means you pay 90% of price
x = original price
Store A : 5% off means price is .95x
then another 10% off would mean .9 * (.95x)
then another 10% off would mean .9 * ( .9 *(.95x)
this equals .7695 x
Store B 25% off means you pay 75%
price is then .75x
price of .75x at store B is < than .7695 x at store A
so B has greater discount
Answer:
Step-by-step explanation: To compare the discounts offered by Store A and Store B, we need to calculate the final price of the item after all discounts have been applied.
For Store A, the successive discounts of 5%, 10%, and 10% can be applied as follows:
The initial price of the item is reduced by 5%, resulting in a price of 0.95 * Price.
The price from step 1 is reduced by an additional 10%, resulting in a price of 0.9 * (0.95 * Price) = 0.855 * Price.
The price from step 2 is reduced by an additional 10%, resulting in a price of 0.9 * (0.855 * Price) = 0.7695 * Price.
For Store B, the single discount of 25% can be applied as follows:
The initial price of the item is reduced by 25%, resulting in a price of 0.75 * Price.
Comparing the final prices of the item at Store A and Store B, we can see that Store B offers a greater discount. The final price of the item at Store A is 0.7695 * Price, while the final price at Store B is 0.75 * Price. Since 0.75 is less than 0.7695, the final price at Store B is lower.
Therefore, Store B offers a greater discount on the item.
For which function i the average rate of change over the interval 1 < x < 5 greater than the average rate of change over the ame interval for the function g(x) = 1. 8x2?
Option D is correct the answer. The average rate of change over the interval 1 < x < 5 is greater than the average rate of change over the same interval for the function g(x) = 1. 8x2 is k(x) = 2x^2
The average rate of change:
Given a function y, the average rate of change S of y=f(x) in an interval (xs,xf) will be given by the following equation:
[tex]S=\frac{f(xf)-f(xo)}{xf-xo}[/tex]
In this problem, we have that:
Interval (1,5), so xf=5,xo=1
Then
[tex]S=\frac{f(5)-f(1)}{4}[/tex]
All options are compared to g(x).
[tex]g(x)=1.8x^{2}[/tex]
g(5) = 1.8*(5)^2 = 45
g(1) = 1.8*(1)^2 = 1.8
[tex]S=\frac{45-1.8}{4} =10.8[/tex]
A.=f(x) = x^2
f(5) = 5^2 = 25
f(1) = 1^2 = 1
[tex]S=\frac{25-1}{4} =6.25[/tex]
Smaller than 10.8, so this is not the answer.
B.=g(x) = 1.2x^2
g(5) = 1.2*(5)^2 = 30
g(1) = 1.2*(1)^2 = 1.2
[tex]S=\frac{30-1.2}{4} =7.2[/tex]
Smaller than 10.8, so this is not the answer.
C.=h(x) = 1.5x^2
h(5) = 1.5*(5)^2 = 37.5
h(1) = 1.5*(1)^2 = 1.5
[tex]S=\frac{37.5-1.5}{4}= 9[/tex]

Answer:
The x-axis interval of 39 to 65 has the smallest rate of change.
Step-by-step explanation:
See the attached worksheet. The interval of x that results in the least change in y can be visually seen by plotting the points and drawing a curve. The curve begins to flatten as x increases. So the smallest rate of change is between the last two points, x = 39 to 65.
This can also be calculated by finding the change in y per a change in x. The table in the graph confirms the earlier observation. Dx and Dy represent the "delta," or difference, D, between the x (Dx) and y(Dy) values. The rate of change is calculated as Dy/Dx, or the change in y divided by the change in x. The results confirm that the 39 to 65 segment is the smallest, at 0.15.

Daliyah is given one point on a line as (3,−1) and the slope of the line as −5. What is the y-intercept of the line?
Answer: The y-intercept is 14
Step-by-step explanation:
The slope intercept is y=mx+b
since we already have the slope, we can write this as
y=-5x+b
substitute the points of (3,-1) into the equation and solve for b
-1=-5(3)+b
-1=-15+b
b=14
The y-intercept is 14
The y-intercept of the line is 14.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = -5
The line passes through the point (3, -1).
The equation of the line is y = mx + c.
y = -5x + c
(3, -1) = (x, y)
-1 = -5 x 3 + c
-1 = -15 + c
-1 + 15 = c
c = 14
Thus,
The y-intercept is 14.
