Find the interest rate for a principal of $5305 and charged $39534 in interest for 20 years
Answer:
37.237%
Step-by-step explanation:
Use the Formula I = P x R x T
P = Principal amount (the beginning balance).
R = Interest rate (usually per year, expressed as a decimal).
T = Number of time periods (generally one-year time periods).
Plug in the values
I = 5305 x R x 20
Solve for R by dividing 20 by 5305
I=5305 x R x 20
20 / 5305 = 0.0037
Answer: 10.56 or 10.6 %
Step-by-step explanation:
5305 x x^20 = 39534
39534/5305 = x^20
20√39534/5305 = x
x = 1.1056
1.1056 x 100 = 110.56
110.56 - 100 = 10.56 or 10.6
assume that the maximum speed your car will go is a linear function of the steepness of the hill is going up or down. SUppose the car can go a maximum of 55 mph up a 5 hill and a maximum of 104 down a 2 hill
The maximum speed of the linear function is y = -7x + 90
Assume that the maximum speed your car will go is a linear function of the steepness of the hill is going up or down?a. we have two points connecting (speed, degree) are (+5,55) and (-2,104) representing (x₁ , y₁) and (x₂, y₂)
Slope = (y₂ - y₁) / (x₂ - x₁)
slope = (104-55) / (-2-5) = 49/-7 = -7 mph/1°
speed = slope x (degree) + b
Solve 'b':
55 = -7 x (5) + b
55 = -35 + b
b = 55 + 35
b = 90
y₁ = -7x₁ + 90
b) What does the speed-intercept equal and what does it represent?
The speed is 90 mph when there is no hill.
c ) What does the degree of steepness-intercept and what does it represent?
Up the hill, the steepness is roughly 12.9 degrees at its maximum. Whenever there is a slope, the car will not move.
d) Interpret the slope in words.
The speed drops by 7 mph for every 1 degree that the hill's steepness increases.
e) If your top speed is 83 mph, how steep is the hill? Be sure to include whether the direction is up or down.
83 = -7 x + 90
83 -90 = -7x
-7 = -7x

Algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)= 50
The x-coordinates where the line y = 2x + 3 intersects the circle is equal to -2 and -4.
What is the equation of a circle?Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;
(x - h)² + (y - k)² = r²
Where:
h and k represents the coordinates at the center of a circle.r represents the radius of a circle.From the information provided, we have the following system of equations:
(x - 3)² + (y + 6)² = 50 ......equation 1.
y = 2x + 3 .............equation 2.
In order to determine the x-coordinates at the point of intersection, we would substitute the equation 2 into equation 1:
(x - 3)² + (2x + 3 + 6)² = 50
(x - 3)² + (2x + 9)² = 50
x² - 6x + 9 + 4x² + 36x + 81 - 50 = 0
5x² + 30x + 40 = 0
x² + 6x + 8 = 0
x² + 6x + 9 = 1
(x + 3)² = 1
Taking the square of both sides of the equation, we have;
x + 3 = ±1
x = ±1 - 3
x = -2 and -4

Find the greatest possible error :19oz
Answer:
0.5 oz
Step-by-step explanation:
You want the greatest possible error associated with the measurement 19 oz.
Measurement errorThe possible error is generally considered to be half the place value of least-significant digit. Here, the least significant digit has a place value of units, so the greatest error is 1/2 unit, or 0.5 ounces.
__
Additional comment
We know that values of 18.5 oz up to 19.4999... oz will round to 19 oz. That is why the greatest error is considered to be 0.5 oz.
In practice, there can be some difficulty associated with knowing that a value is 18.5 instead of 18.49. Hence real-world error may actually be slightly larger than 0.5 oz. In math, we ignore that case.

On January 1, 2019, Marblehead, Massachusetts had a population of approximately 19,800 people. On that date, 1,098 Marblehead residents were living with asthma. Between January 1, 2019 and September 1, 2019, there were 495 newly diagnosed cases of asthma in Marblehead. You can assume that the population (19,800) remained constant throughout 2019.
What was the prevalence of asthma in Marblehead on January 1, 2019?
What was the prevalence of asthma in Marblehead on September 1, 2019?
What was the incidence of asthma in Marblehead between January 1, 2019 and September 1, 2019?
Based on the information provided above, it is NOT possible to calculate asthma incidence rate in Marblehead for the year 2018.
The prevalence of asthma on January 1, 2019 is 0.055, the prevalence of asthma on September 1, 2019 is 0.080, the incidence of asthma between January 1 and September 1 is 0.025, there is not possible to calculate asthma incidence rate for the year 2018.
How to calculate prevalence and incidence asthma?Prevalence is the formula to determine the rate of some case based on population. This can be calculated by divide the case by the population.
Incidence rate is same as prevalence in some factor except it only calculate time range and for this case it have same formula which is we can calculate incidence rate by divide the case by the population.
So, for January 1, 2019 is
Prevalence = 1,098 / 19,800
= 0.055
For September 1, 2019 is
Prevalence = (1,098 + new 495) / 19,800
= 1,593 / 19,800
= 0.080
For incidence of asthma between January 1 and September 1 is
Incidence = 495 / 19,800
= 0.025
For 2018 because we are not provided with data for that year so it is impossible to calculate it.
Thus, the prevalence in January 1 is 0.055, September 1 is 0.080, and incidence between January 1 and September 1 is 0.025, and also there is not possible to calculate asthma incidence rat for the year 2018.

A cruise ship traveled to Madagascar and
back. On the trip there it traveled 12 km/h
and on the return trip it went 18 km/h.
How long did the trip there take if the
return trip took six hours?
A) 12 hours
C) 9 hours
B) 10 hours
D) 7 hours
To find the time it took the cruise ship to travel to Madagascar, we need to use the formula for distance, which is distance = speed x time. We are given the distance and the speed of the ship on the trip there, so we can solve for the time by dividing the distance by the speed:
time = distance / speed
We are told that the distance of the trip there was the same as the distance of the return trip, which took 6 hours. We are also told that the ship traveled 12 km/h on the trip there, so the distance of the trip there was 12 km/h x 6 h = 72 km.
Now we can plug this information into the formula to solve for the time:
time = 72 km / 12 km/h = <<72/12=6>>6 hours
Therefore, it took the cruise ship 6 hours to travel to Madagascar. The correct answer is therefore (A) 12 hours.
determine the z transform for each of the following sequences. sketch the pole-zero plot and indicate the region of convergence. indicate whether or not the (discrete time) fourier transform of the sequence exists.
The Fourier transform of this sequence does not exist
What is Fourier Transform?
The output of a Fourier transform is a function of frequency and is a mathematical transformation that breaks down functions into frequency components.
To determine the z-transform of a given sequence, we need to find the sum of the sequence's terms multiplied by z raised to the negative of the term's position. For example, given a sequence x[n], the z-transform X(z) is given by:
[tex]X(z) = sum_{n=-infinity}^{infinity} x[n] * z^{-n}[/tex]
To sketch the pole-zero plot of a z-transform, we need to plot the poles (values of z where the z-transform is infinite) and zeros (values of z where the z-transform is zero) in the complex plane. The region of convergence (ROC) is the set of values of z for which the sum defining the z-transform converges.
[tex]x[n] = a^n u[n][/tex], where a is a constant and u[n] is the unit step function[tex](u[n] = 1 for n > = 0[/tex] and [tex]u[n] = 0 for n < 0)[/tex]
The z-transform of this sequence is given by:
[tex]X(z) = sum_{n=0}^{infinity} a^n * z^{-n}= 1 / (1 - a*z^{-1})[/tex]
This z-transform has a pole at z = 1/a and a zero at z = 0. The pole-zero plot consists of a single pole at 1/a in the complex plane. The ROC is the set of values of z such that [tex]|a*z^{-1}| < 1[/tex], which is the region inside the unit circle centered at the origin. The Fourier transform of this sequence exists.
[tex]x[n] = (-1)^n u[n].[/tex]
The z-transform of this sequence is given by:
[tex]X(z) = sum_{n=0}^{infinity} (-1)^n * z^{-n}= 1 / (1 + z^{-1})[/tex]
This z-transform has a pole at z = -1 and a zero at z = 0. The pole-zero plot consists of a single pole at -1 in the complex plane. The ROC is the set of values of z such that [tex]|z^{-1}| < 1[/tex], which is the region inside the unit circle centered at the origin. The Fourier transform of this sequence exists.
[tex]x[n] = n^2 u[n].[/tex]
The z-transform of this sequence is given by:
[tex]X(z) = sum_{n=0}^{infinity} n^2 * z^{-n}= z^{-2} / (1 - z^{-1})^3[/tex]
This z-transform has poles at z = 1, z = 1, and z = 1. The pole-zero plot consists of three poles at the origin in the complex plane. The ROC is the set of values of z such that [tex]|z^{-1}| > 1[/tex], which is the region outside the unit circle centered at the origin.

The fraction 1¹/₂ + ⁵/₇ = 2³/₁₄
What are fractions?Fractions are numbers written in the form a/b where a and b are integers and b ≠ 0.
How to find what 1¹/₂ + ⁵/₇?Since we have the fractions 1¹/₂ and ⁵/₇ and we want to compute the sum
1¹/₂ + ⁵/₇, we re-write the first fraction as an improper fraction.
So, 1¹/₂ = ³/₂
Now, re-writting the equation, we have
³/₂ + ⁵/₇
To find the sum, wetake the L.C.M of both numbers which 2 × 7 = 14.
So, we make both denominators equal to the L.C.M.
So,
³/₂ × ⁷/₇ + ⁵/₇ × ²/₂ = ²¹/₁₄ + ¹⁰/₁₄
= (21 + 10)/14
= 31/14
= (28 + 3)/14

A sector with central angle theta is cut froma circle of radius 10 inches and the edges of the secotr are brought toegether to ormnr a cone find the amgnitude of theta such that thte volume of the conbe is a maximum
So, the maximum volume of the cone is approximately 1047.19 cubic inches.
The volume of a cone is given by the formula V = (1/3) * pi * r^2 * h, where r is the radius of the base and h is the height of the cone. In this case, the height of the cone is the radius of the circle, which is 10 inches, and the radius of the base is half the length of the circumference of the sector, which is (theta/360) * 2 * pi * 10 inches.
We want to find the value of theta that maximizes the volume of the cone. We can do this by taking the derivative of the volume formula with respect to theta, setting it equal to 0, and solving for theta.
V = (1/3) * pi * r^2 * h
= (1/3) * pi * ((theta/360) * 2 * pi * 10)^2 * 10
= (1/3) * pi * (theta/36)^2 * 100
dV/dtheta = (2/3) * pi * (theta/36) * (100/36)
= (2/3) * pi * theta/36
Setting dV/dtheta = 0 and solving for theta, we get theta = 0.
Since the magnitude of theta must be positive, the maximum volume occurs when theta = 0, which means that the entire circle is used to form the cone. The maximum volume of the cone is then
V = (1/3) * pi * r^2 * h
= (1/3) * pi * (10)^2 * 10
= (1/3) * pi * 100 * 10
= (1/3) * pi * 1000
= approximately 1047.19 cubic inches
So, the maximum volume of the cone is approximately 1047.19 cubic inches.

The statement is true. Functions that are concave upward are always increasing.
What is Concave Upward Function?
Where the derivative f′ is growing, a function f is concave up (or upwards). This is equivalent to the derivative of f′, which is represented by the notation f′′f, start superscript, prime, end superscript, positive.
Explanation:
If a function is concave upward on an interval, it must be increasing on the interval. Given statement is true. Functions that are concave upward are always increasing.
A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval.
At interval if function is increasing then functions that are concave upward are always increasing.
Hence, The statement is true. Functions that are concave upward are always increasing.

Can someone please answer this problem for me.
Answer:
$1 per movie
$5.50 per video game
Step-by-step explanation:
We know 5 movies and 2 video games cost $16 and 3 movies and 8 video games cost $47.
Let x be the cost of 1 movie and y be the cost of a video game.
5x + 2y = 16
3x + 8y = 47
In the first equation, lets solve for y
2y = 16 - 5x
y = 8 - 2.5x
Now, we can substitute this into the other equation.
3x + 8(8 - 2.5x) = 47
3x + 64 - 20x = 47
-17 x = - 17
x = 1
So a movie costs $1 to rent.
2y = 16 - 5(1)
2y = 11
y = 5.5
A video game costs $5.50 to rent.
