Suppose that $10,083 is invested at an interest rate of 6.8% per year, compounded continuously.
a) Find the exponential function that describes the amount in the account after time t, in years.
b) What is the balance after 1 year? 2 years? 5 years? 10 years?
c) What is the doubling time?
Answer:
a) The exponential function is \(A(t) = 10083(1.068)^t\)
b)
The balance after 1 year is of $10,768.644
The balance after 2 years is of $11,500.91
The balance after 5 years is of $14,010.25.
The balance after 10 years is of $19,467.15
c)
The doubling time is of 10.54 years.
Step-by-step explanation:
Continuously compounded interest:
The amount of money earning after t years, with interest compounded continuously, is given by:
\(A(t) = A(0)(1+r)^t\)
In which A(0) is the amount of the initial investment and r is the growth rate, as a decimal.
a) Find the exponential function that describes the amount in the account after time t, in years.
Suppose that $10,083 is invested at an interest rate of 6.8% per year
This means, respectively, that \(A(0) = 10083, r = 0.068\)
So
\(A(t) = A(0)(1+r)^t\)
\(A(t) = 10083(1+0.068)^t\)
\(A(t) = 10083(1.068)^t\)
b) What is the balance after 1 year? 2 years? 5 years? 10 years?
After 1 year:
\(A(1) = 10083(1.068)^{1} = 10,768.644\)
The balance after 1 year is of $10,768.644
After 2 years:
\(A(2) = 10083(1.068)^{2} = 11,500.91\)
The balance after 2 years is of $11,500.91.
After 5 years:
\(A(5) = 10083(1.068)^{5} = 14,010.25\)
The balance after 5 years is of $14,010.25.
After 10 years:
\(A(10) = 10083(1.068)^{10} = 19,467.15\)
The balance after 10 years is of $19,467.15.
c) What is the doubling time?
This is t for which \(A(t) = 2A(0)\). So
\(A(t) = A(0)(1.068)^t\)
\((1.068)^t = 2\)
\(\log{(1.068)^t} = \log{2}\)
\(t\log{1.068} = \log{2}\)
\(t = \frac{\log{2}}{\log{1.068}}\)
\(t = 10.54\)
The doubling time is of 10.54 years.
Does this graph represent a function? Why or why not?
Answer:
No, because it fails the line test.
Step-by-step explanation:
The line test is a test to tell whether or not a graph represents a function. If the line passes through the graph at one point, it is a function. x's length is at least 8, which means the line would cut through more than one point. Therefore, it is not a function.

What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Given the table where a number of hours and miles are shown,
The unit rate of first data = 69/1.5 = 46
the unit rate of second data = 161/3.5 = 46
And so on
So, 46 will be constant of the function
It means the function will be y = 46x and the rate of the function will be y/x = 46.
Hence "The speed where Trish is driving is 46 miles per hour".

Find the distance between (5, -4) and (-1, -2)
Answer: The distance is sqrt(40).
Step-by-step explanation:
Let's use the Pythagorean Theorem (a^2 + b^2 = c^2)
(Look at the image I attached)
Let's set a = 2 and b = 6. The mystery side is c, which is opposite to the right angle that is formed when you draw perpendicular lines from each of the points.
(2)^2 + (6)^2 = c^2 <--- First, we need to simplify
4 + 36 = c^2
40 = c^2 <--- Now, we need to take the square root of both sides.
c = sqrt(40)
So, the distance between (5, -4) and (-1, -2) is sqrt(40). I recommend looking at some videos on Khan Academy if you need more help! Let me know if you want me to attach a link that you can visit.
Find the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0. Also, show in the graph.
The inversion point of (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0 is (6, 7).
Finding the inversion pointTo find the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0, we need to follow these steps:
Step 1: Write the equation of the given circle in standard form by completing the square for x and y: (x - 2)² + (y - 3)² = 16.
Step 2: Find the radius of the circle by taking the square root of the constant term: r = √16 = 4.
Step 3: Find the distance between the given point (4, 5) and the center of the circle (2, 3) using the distance formula: d = √[(4 - 2)² + (5 - 3)²] = √8.
Step 4: Use the formula for inversion point to find the coordinates of the inversion point (x', y'): (x', y') = (h + r²/d² * (x - h), k + r²/d² * (y - k)), where (h, k) is the center of the circle and r is the radius.
Plugging in the values, we get: (x', y') = (2 + 4²/8 * (4 - 2), 3 + 4²/8 * (5 - 3)) = (6, 7).
Therefore, the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0 is (6, 7).

The statement "the Y value of function I would ask equals -2 is greater than the Y value function be when I ask equals negative to the Y value function a 1X equals -2 is less than the Y value a function be one x was -2" is true.
Given, two functions y = -2f(x) = 1/x
To determine whether the statement "the Y value of function I would ask equals -2 is greater than the Y value function be when I ask equals negative to the Y value function a 1X equals -2 is less than the Y value a function be one x was -2" is true or false, we need to find the value of Y for both functions when x = -2.
Substituting x = -2 in the functions we get:I would ask y = -2(-2) = 4f(-2) = 1/(-2) = -1/2Therefore, the Y value of the function I would ask is greater than the Y value function be when I ask equals negative to the Y value function a 1X equals -2 is less than the Y value a function be one x was -2. Hence, the given statement is true.

Maggie and Alan drive for a total of 32 hours.
How long did each person drive?
Answer:
Step-by-step explanation:
Let the number of hours driven by Maggie be x and that of Alan be y
If Maggie and Alan drive for a total of 32 hours, then;
x+y = 32 ..... 1
Also if Maggie drives three times the number of hours that Alan drives on their vacation, then x = 3y ...... 2
Substitute eqn 2 into 1;
x+y = 32
3y+y = 32
4y = 32
y = 32/4
y = 8 hours
Since x = 3x
x = 3(8)
x = 24 hours
Hence Maggie drives for 24 hours and Alan drives for 8 hours

Step-by-step explanation:
The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.
Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:
number of people that like MATH 123 = 68% of the population
number of people that like MATH 123 = 0.68 * 1000

Evaluate log4 exponent 0.5
We can claim that after answering the above question, the So, logarithm \(log4 (0.5^(1/2)) =-0.0752\)
what is logarithm?The logarithm is a power's reciprocal in mathematics. Accordingly, the exponent by which b must be raised to obtain a number x equals the logarithm of that number in base b. For instance, since 1000 = 103, its base-10 logarithm is 3, or log10 = 3. As an illustration, the base 10 logarithm of 10 is 2, while the square of 10 is 100. Log 100 = 2. To answer a question like, For example, how many times must a base of 10 be multiplied by itself to achieve 1,000, a logarithm (or log) is the mathematical term utilized. The solution is 3 (1,000 = 10 10 10).
Using the following property of logarithms:
\(log_a (b^c) = c * log_a (b)\\log4 (0.5^(1/2))\\(1/2) * log4 (0.5)\\log4 (0.5) = log (0.5) / log (4)\\log (0.5) ≈ -0.3010\\log (4) = 2\)
Therefore,
\(log4 (0.5) ≈ -0.3010 / 2 ≈ -0.1505\\(1/2) * log4 (0.5) ≈ (1/2) * (-0.1505) ≈ -0.0752\\\)

The measure of the angle ABD is (3x + 29)
What is Bisecting angles?Bisecting angles is the process of dividing an angle into two congruent angles. In geometry, an angle bisector is a line or ray that divides an angle into two equal parts.
When an angle is bisected, each of the two angles formed is called a half-angle or bisector angle, and the point where the angle is bisected is called the vertex of the angle.
Here we have
BD bisects ABC and ∠ABC = 6x+58
When a straight bisect an angle then the measure of the resultant 2 angles will be equal in measure
Here BD bisected ABC
The resultant angles will be ∠ABD and ∠DBC
Hence,
=> ∠ABC = ∠ABD + ∠DBC
=> ∠ABC = ∠ABD + ∠ABD [ Since two angles are equal
=> ∠ABC = 2∠ABD
From the given data,
=> 6x + 58 = 2∠ABD
=> 2 ∠ABD = 2(3x + 29)
=> ∠ABD = (3x + 29)
Therefore,
The measure of the angle ABD is (3x + 29)

iii. 0, 1, 2, 3, 4, 5 personality preferences in common
iv. 0, 1, 2, 3, 4 personality preferences in common
Answer:
a. Probability (0) = 36/375 = 0.096
Probability (1) = 61/375 = 0.162
Probability (2) = 124/375 = 0.330
Probability (3) = 128/375 = 0.341
Probability (4) = 30/375 = 0.08
b. iii) Yes, because they cover the entire sample space.
c. Obviously, the sample space in this problem is iv.
iv = {0,1,2,3,4} personality preferences in common.
Step-by-step explanation:
In this question, we are asked to calculated the probability of preferences in common.
As we know, the general formula for probability is:
Probability = Number of favorable outcome/ Total number of favorable outcomes
Data Given:
For 0 = 36
For 1 = 61
For 2 = 124
For 3 = 128
For 4 = 128
Total = 375 Married Couples
Probability (0) = Number of favorable outcomes/ Total Number of Favorable outcomes
Probability (0) = 36/375 = 0.096
Similarly,
Probability (1) = 61/375 = 0.162
Similarly,
Probability (2) = 124/375 = 0.330
Similarly,
Probability (3) = 128/375 = 0.341
Similarly,
Probability (4) = 30/375 = 0.08
b. Total Probability can never be greater than 1 and less than 0.
So, Probabilities of the sample will add up to 1
iii) Yes, because they cover the entire sample space.
Total Probability = P(0) + P(1) + P(2) + P(3) + P(4) = 1
Total Probability = 0.09 + 0.16 + 0.33 + 0.34 + 0.08 = 1
