Answer:
A= 2000*(1+0.05)^t
Explanation: The equation represents the compound interest formula where A is the amount of money in the account, P is the principal amount (initial investment) which is $2,000, r is the interest rate (expressed as a decimal) which is 5% or 0.05, and t is the number of years. The formula shows that the account balance will increase by 5% each year, meaning the interest will be added to the principal and the new interest will be calculated on the new balance.

In the diagram below, (5, 2) is the midpoint of a segment with one endpoint (-1, 8). What is the other endpoint of the segment? Show your work or explain how you find your answer.
The line segment AB has point B(x, y) = (11, - 4) as its other endpoint.
How to determine the coordinates of the missing endpoint of a line segment
Herein we find the case of a line segment, of which the coordinates of its midpoint and one of its endpoints are known. Midpoint and endpoints are related by following expression:
0.5 · A(x, y) + 0.5 · B(x, y) = M(x, y)
Where:
A(x, y), B(x, y) - EndpointsM(x, y) - MidpointIf we know that A(x, y) = (- 1, 8) and M(x, y) = (5, 2), then the coordinates of the other midpoint are:
0.5 · (- 1, 8) + 0.5 · B(x, y) = (5, 2)
(- 1, 8) + B(x, y) = 2 · (5, 2)
(- 1, 8) + B(x, y) = (10, 4)
B(x, y) = (11, - 4)
The point B(x, y) = (11, - 4) is an endpoint of line segment AB.

Determine the solutions of the equation. What solution makes sense for the situation?
The dimensions of the rectangle are 8 inches as width and 13 inches as length.
How to calculate the equation?An equation simply has to do with the statement that illustrates the variables given. In this case, it is vital to note that two or more components are considered in order to be able to describe the scenario.
The equation is given as:
x² + 5x - 104.
x² + 13x - 8x - 104
x(x + 13) - 8 (x + 13).
x - 8 = 0
x = 0 + 8
Width = 8
Length = x + 5
= 8 + 5.

Identify the transformed function that represents f(x) = ln x stretched vertically by a factor of 5, reflected across the x-axis, and shifted by 6 units left.
A. G(x) = -5ln (x - 6)
B. G(x) = 5ln (x + 6)
C. G(x) = -5ln (x + 6)
D. G(x) = 5ln (x - 6)
The function after transformation is G(x) = -5 ln (x+6) is the correct answer.
The correct answer is an option (C)
Here, the function is f(x) = ln x
A function f(x) is stretched vertically by a factor of 5.
As we know for a vertical stretch, we need to multiply the whole function by the factor of stretching.
If the stretching factor is m, then after stretching the function becomes
⇒ m × f(x)
Here, stretching factor m = 5
So the transformed function would be,
G(x) = 5 f(x)
⇒ G(x) = 5 ln x
Now, function is reflected across the x-axis, so the function becomes
⇒ G(x) = -5 ln (x+6)
Then the function is shifted by 6 units left, so after translation the function becomes
⇒ G(x) = -5 ln (x+6)
Thus, we can conclude that the function f(x) = ln x after transformation would be G(x) = -5 ln (x+6) is the correct answer.

I need help with substitution the two parts are 4x+5y=48 and 7x-3y=-10. i need to find x and y
The solution to the simultaneous equation is x = 38 and y = 8
How to determine the valueFrom the information given, we have the equations;
4x+5y=487x-3y=-10From equation (1), make 'x' the subject of formula;
4x = 48 - 5y
Divide both sides by 4
x = 48 - 5y/4
Substitute the value x in equation (2)
7(48 - 5y/4) - 3y = -10
expand the bracket
336 - 35y/4 - 3y = -10
Find the lowest common multiple
336 - 35y - 12y/4 = -10
336 - 47y/4 = -10
cross multiply
336 - 47y = -40
collect like terms
-47y = 376
y = 8
Substitute the value into equation 3
x = 48 - 5(8)/4
x = 48 - 10
x = 38
Hence, the values are 38 and 8

Answer: 2.294524311274043, 4.294524311274043, 6.294524311274043 and 8.294524311274043 radians.
Step-by-step explanation: We can start by isolating the sin function on one side of the equation:
sin (2x-4) = 2/3
Next, we can use the inverse sine function (sin^-1) to find the value of 2x-4:
2x-4 = sin^-1(2/3)
We know that the domain of the inverse sine function is [-1,1], so the value of 2/3 falls in that range. To find the value of x, we can add 4 to both sides and divide both sides by 2:
x = (sin^-1(2/3) + 4) / 2
The value of sin^-1(2/3) is approximately 0.5890486225480862 radians and that's the first solution in the range [0, pi], and we can add multiples of pi to get the other solutions.
x = (0.5890486225480862 + 4) / 2 = 2.294524311274043 radians (in the range [0, pi])
x = (0.5890486225480862 + 4 + pi) / 2 = 4.294524311274043 radians (in the range [pi, 2pi])
x = (0.5890486225480862 + 4 + 2pi) / 2 = 6.294524311274043 radians (in the range [2pi, 3pi])
x = (0.5890486225480862 + 4 + 3pi) / 2 = 8.294524311274043 radians (in the range [3pi, 4*pi])
So there are four solutions to this equation: 2.294524311274043, 4.294524311274043, 6.294524311274043 and 8.294524311274043 radians.
[tex]3\sin(2x-4)=2\implies \sin(2x-4)=\cfrac{2}{3}\implies 2x-4=\sin^{-1}\left( \cfrac{2}{3} \right) \\\\\\ 2x=\sin^{-1}\left( \cfrac{2}{3} \right)+4\implies x=\cfrac{\sin^{-1}\left( \frac{2}{3} \right)+4}{2} \\\\\\ x=\cfrac{\sin^{-1}\left( \frac{2}{3} \right)}{2}+2\implies x\approx\cfrac{0.73}{2}+2\implies \stackrel{II~Quadrant}{x\approx 2.365}\hspace{5em}\stackrel{III~Quadrant}{\stackrel{\frac{\pi -0.73}{2}+2}{x\approx 3.206}}[/tex]

A tank can be filled by an inlet pipe in 12 hours and emptied by a drain pipe in 16 hours. How long will it take to fill the tank if both pipes are left open?
It will take 48 hours, to fill the tank if both pipes are left open simultaneously.
We are given the following data -
The time taken to fill the tank by inlet pipe = 12 hrs
so, the rate of filling = 1/12
The time taken to empty the tank by drain pipe = 16 hrs
so, the rate of emptying = - 1/16
Therefore, the total work done by both pipes can be given by the following formula -
(1/rate of filling) + (1/rate of emptying) = (1/rate of net change)
1/12 + (-1/16) = (1/Rn)
Therefore, (1/Rn) = 1/12 - 1/16 = 1/48
To find how long it will take to fill the tank, we need to find the reciprocal of the rate of net change:
1/Rn = 1/(1/48)
Rn = 48
So it will take 48 hours, to fill the tank if both pipes are left open.

Step-by-step explanation:
You want to know how far Dylan travelled if he drove 50 mph for 3.5 hours and 65 mph for 2 hours.
DistanceDistance is the product of speed and time. The total distance Dylan travelled will be the sum of lengths of the legs of his trip.

jose needs 20 1/3 feet of string for a project. he has lengths of string that are 9 1/2 feet, 3 1/4 feet and 4.5 feet long does jose have enough string for his project?
Answer: To check if Jose has enough string for his project, we need to add the lengths of the strings he has and compare it to the amount of string he needs for the project.
The length of the first string is 9 1/2 feet, the second string is 3 1/4 feet and the third string is 4.5 feet.
To add these lengths we need to convert them all to the same unit of measurement.
3 1/4 feet can be converted to 3.25 feet
So the total length of the strings Jose has is 9 1/2 + 3.25 + 4.5 = 17.25 feet
Jose needs 20 1/3 feet of string for his project, and he has 17.25 feet of string.

The child has 14 quarters and 28 dimes if child's bank contains $6.30 in dimes and quarters.
What is Algebraic expression ?
Algebraic expression can be defined as the combination of variables and constants.
With coin problems you need to keep track of the count of the coins and the value.
d = number of dimes
10d = value of the dimes in cents
q = number of quarters
25q = value of the quarters in cents
10d + 25q = 630 cents
d = 2q
substitute
10(2q) + 25q = 630
20q + 25q = 630
45q = 630
q = 14
d = 2q
d = 2*14 = 28
Check the values to be sure this answer is right.
25(14) = 350 cents
10(28) = 280 cents
