The amount in the account after the given time if compounded semiannually to the nearest cent is $1104.2
Compound interestInterest is any amount added on a sum of money over a period of time. The formula for calculating the compound interest is:
A = P(1+r/n)^nt
Given
Principal = $1000
rate r = 5% = 0.05
time = 3years
n = 2 (semi annually)
Substitute the given parameters
A = 1000(1 + 0.05/3)^3(2)
A= 1000(1.1042)
A = $1104.2
Hence the amount in the account after the given time if compounded semianually to the nearest cent is $1104.20

A. g(x) = |3|
B. g(x) = 3|4|
O C. g(x) = |x - 3|
D. g(x) = 1/3|x|
Answers
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|

Answers
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

Answer:

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

The radius of a cylinder is 6.0 inches and the height is 9.0 inches, what is the volume of the cylinder? if the cylinder is enlarged by a linear scale factor of 3, what is the volume of the enlarged cylinder?
Answers
Answer:
A) The volume of the cylinder is 1017.9 in³.
B) The volume of the enlarged cylinder is 27,482.7 in³.
Step-by-step explanation:
What is the volume of the cylinder?The radius of the cylinder is r = 6 in and the height is h = 9 in.
The volume of a cylinder can be found using the formula:
V = πr²hSubstitute r = 6 and h = 9 into the formula.
V = π(6)²(9)V = π(36)(9)V = π(324)V = 1017.876The volume of the cylinder is 1017.876 in³.
What is the volume of the enlarged cylinder?If the cylinder is enlarged by a factor of 3, this means that each dimension is getting increased by 3.
Therefore, we need to multiply the original volume by a factor of three cubed; 3³.
V_enlarged = V · 3³V_enlarged = 1017.876 · 27 = 27482.652 in³The volume of the enlarged cylinder is 27,482.652 in³.

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?
Answers
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.

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

Answers
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

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]

x - 9 = -10
x = -1
For the y-coordinate, we have that:

y + 8 = 10
y = 2.
