Brandon invested $41,000 in an account paying an interest rate of 3% compounded
continuously. Evan invested $41,000 in an account paying an interest rate of 37%
compounded quarterly. To the nearest dollar, how much money would Brandon have
in his account when Evan's money has doubled in value?
After 1.959 years Evan's money has doubled in value and at that time Brandon have $43,481.78 in his account.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
Let's suppose, after t time, Evan's money has doubled in value.
[tex]\rm 2P = P(1+\dfrac{0.37}{4})^{4t}[/tex]
After solving
x = 1.959 years
Use x = 1.959 years to get how much money would Brandon have.
[tex]\rm A = P e^{rt}[/tex]
[tex]\rm A = 41000\times e^{0.03\times 1.959}[/tex]
A = $43,481.78
Thus, after 1.959 years Evan's money has doubled in value and at that time Brandon have $43,481.78 in his account.

Two companies offer river tubing trips.
• The first company charges $7.50 rental fee for the tube and $3.00 an hour.
• The second company charges $10.50 rental fee for the tube and $2.00 an hour.
What is the minimum number of hours a person would need to rent a tube in order for
the second company to be a better deal?
Minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.
What is a mathematical model?A mathematical model is the model which is used to explain any system, the effect of the components by study and estimate the functions of systems.
Two companies (first and second) offers river tubing trips and the rates of them are as follows: The first company charges $7.50 rental fee for one tube, with a charge of $3.00 an hour.
For the x hours, the charge of the company is,
7.50+3.00x
The second company charges $10.50 rental fee for one tube with a charge of $2.00 an hour. For the x hours, the charge of the company is,
10.50+2.00x
Let x is the hour at which the cost of both companies are equal. Thus,
7.50+3.00x=10.50+2.00x
3x-2x=10.5-7.5
x=2.5
Thus, the minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

Step-by-step explanation:
To find:-

It is given that the crew made 8¼ miles of road in 5½ days . To find the rate of work done , simply divide the total length of road nade by total time taken . That would be , ( rate is represented by "r" . )
[tex]:\implies \sf r = 8\dfrac{1}{4}\div 5\dfrac{1}{2} \ miles/day\\[/tex]
Convert the mixed fraction into improper fraction.
[tex]:\implies \sf r = \dfrac{33}{4}\div \dfrac{11}{2} \ miles/day \\[/tex]
For dividing them , multiply the reciprocal of 11/2 by 33/4 as ,
[tex]:\implies \sf r = \dfrac{33}{4}\times \dfrac{2}{11} \ miles/day\\[/tex]
[tex]:\implies \sf r = \dfrac{3}{2} \ miles/day \\[/tex]
[tex]:\implies \sf \pink{ r = 1\dfrac{1}{2}\ miles/day } \\[/tex]
Hence the unit rate of constructing the road is 1½ miles/day .

If you vertically compress the absolute value parent function, f(x) = 1x1, by a
factor of 3, what is the equation of the new function?
A. g(x) = |3|
B. g(x) = 3|4|
O C. g(x) = |x - 3|
D. g(x) = 1/3|x|
Answer:
your answer should be c
Step-by-step explanation:
5 star?
If you vertically compress the absolute value parent function, f(x) = 1x1, by a factor of 3 then the equation of the new function is g(x) = (1/3)|x|
What is a function?A relation is a function if it has only One y-value for each x-value.
The absolute value function, f(x) = |x|, has a "V" shape with the vertex at (0, 0).
f(x) can also be called as parent function.
A parent function is the simplest function that still satisfies the definition of a certain type of function
When we vertically compress the graph by a factor of 3, we are multiplying the y-value by 1/3.
So the new function g(x) can be expressed as:
g(x) = (1/3) f(x)
g(x) = (1/3)|x|
Hence, if you vertically compress the absolute value parent function, f(x) = 1x1, by a factor of 3 then the equation of the new function is g(x) = (1/3)|x|

d-y=-1/8(x-2)^2-3
WILL GIVE BRAINLIEST
Answer:
D. y = -1/8(x-2)² - 3
Step-by-step explanation:
General eqaution of a parabola : y = a(x-h)² + k where (h,k) is the vertex and a determines whether the parabola goes up or down as well as the width of the parabola
step 1 identify vertex
the vertex is the point that starts the curve
the vertex appears to be at (2,-3)
step 2 plug in h and k using the x and y values of the vertex
again we have y = a(x-h)² + k where (h,k) is the vertex
here the vertex is (2,-3) so h = 2 and k = -3
we get y = a(x-2)² - 3
because the curve goes down a must be negative 1/8
so the final equation would be y = -1/8(x-2)² - 3 meaning D would be the answer
The price went down by 15%, and went 340 money. What was the previous price? ASAPP PLSS
The previous price given the percentage decrease is 400.
How to find the previous price?It follows from the task content that the previous price of the commodity is required;
let, x = previous price
New price = 340
Percentage decrease = 15%
Hence, it follows from the given information that;
340 = x - (15% × x)
340 = x - (0.15x)
340 = 0.85x
x = 340/0.85
x = 400
Therefore, the previous price given the percentage decrease is 400.

On a coordinate plane, a line is drawn from point a to point b. point a is at (9, negative 8) and point b is at (negative 6, 7). what are the x- and y- coordinates of point p on the directed line segment from a to b such that p is two-thirds the length of the line segment from a to b? x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 (2, –1) (4, –3) (–1, 2) (3, –2)
Using proportions, it is found that the coordinates of p in the line segment are given as follows: (-1,2).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the points are:
Point a(9, -8).Point b(-6, 7).Point p(x, y).p is two-thirds the length of the line segment from a to b, hence:
[tex]p - a = \frac{2}{3}(b - a)[/tex]
For the x-coordinate, we have that:
[tex]x - 9 = \frac{2}{3}(-6 - 9)[/tex]
x - 9 = -10
x = -1
For the y-coordinate, we have that:
[tex]y + 8 = \frac{2}{3}(7 - (-8))[/tex]
y + 8 = 10
y = 2.

I would very much like to thank Aklee18oo for everything. this is my last question please see the attachment.
Answer:
8mm
Step-by-step explanation:
The volume of a cylinder is the base area times the height. The base is a circle, and we are not given the radius, so let the radius of the circle of the base of the circle be r. The area of a circle would be [tex]\pi r^{2}[/tex]. This multiplied by the height, which is 15, is [tex]15\pi r^{2}[/tex]. The volume is given to be 753.6, so we can make this an equation:
753.6 = [tex]15\pi r^{2}[/tex]
We are told to use 3.14 for pi, so:
[tex]753.6 = 15 * 3.14 * r^{2}[/tex]
[tex]r^{2} = 16[/tex]
[tex]r = 4[/tex]
The diameter is twice the radius, so the diameter is 8mm.
Answer:
8 mm
Step-by-step explanation:
Formula to find volume :
Volume (cylinder) = πr²h
⇒ 753.6 = 3.14 × r² × 15
⇒ 47.1 × r² = 753.6
⇒ r² = 753.6/47.1
⇒ r² = 16
⇒ r = 4 mm
Relating radius and diameter :
Diameter = 2 × Radius
⇒ Diameter = 2 × 4 mm
⇒ Diameter = 8 mm

Pls explain bc I’m having finals and I need a bit more help with this
Answer:
81/5 or 16 1/5.
Step-by-step explanation:
First convert the mixed number to an improper fraction:
3 6/7
= (3*7 + 6) / 7
= 27/7.
So we have
27/7 / 5/21
Invert the second fraction and multiply:
= 27/7 * 21/5
= (27*21) / (7*5)
= (27*3) / 5 ( as 21/7 = 3)
= 81/5

Step-by-step explanation:
4th and final attempt:
10 * 5 + 2(10x + 2x) + 2(5x) = 104
50 + 2(12x) + 10x = 104
50 + 24x + 10x = 104

34x = 104 - 50
34x = 54
x = 54 / 34
