michael wittry has been investing inhis roth IRA retirement account for 20 years. Two years ago his account was worth $215,658. after losing 1/3 of its origional value, it then gained 1/2 of its new value back, what is the current value of his roth IRA?
His current value is 215658 dollars.
How to calculate a fraction of amount of a total amount ?To calculate a fraction of amount of a total amount just multiply the given fraction to the total amount.
According to the given question
Michael wittry has been investing in his roth IRA retirement account for 20 years.
Two years ago his account was worth $215,658.
1/3rd of it's original value is
= (1/3) × 215658
= 71886 dollars.
∴ Remaining value is
=(215658 - 71886)
=143772 dollars.
After some time it gained half of it's new value back
∴ Half of this new value is
(1/2) × 143772
= 71886 dollars.
So , the current value is
(143772 + 71886)
=215658 dollars.
Actually his currect value of roth IRA is same as it was two years ago.

Find the dimensions of a rectangle with a perimeter of 148 feet that has the maximum area
The dimensions of the rectangle with a perimeter of 148 feet that has the maximum area would be 37 feet by 37 feet, forming a square. The maximum area of the rectangle is 1369 square feet.
Explanation:To find the dimensions of a rectangle with a known perimeter and the maximum area, first understand that the rectangle with the maximum area is a square. In this case, the perimeter is 148 feet.
To calculate the side length of the square, divide the perimeter by 4. Thus, the side of the square would be 148 feet / 4 = 37 feet. Therefore, the maximum area will be achieved when each side of the rectangle is 37 feet long, making it a square with these dimensions.
The maximum area of such a rectangle, which in this case is a square, is obtained by squaring the side length: Area = side × side = 37 feet × 37 feet = 1369 square feet.

Matlab the equation of a circle with its center at x=3 and y=2 is given by , where r is the radius of the circle. first derive the equation(symbolically) of the tangent line to the circle at the point on the upper part of the circle ( and ). then for specific values of r, , , make a plot of the circle and the tangent line. (r=9, )
To derive the equation of the tangent line to the circle, differentiate the circle equation implicitly and substitute the coordinates of a point on the circle to find the specific equation. For r = 9 and x = 3, the specific equation of the tangent line is y = 9 + 3x. Use software like Matlab or a graphing calculator to plot the circle and the tangent line.
Explanation:To derive the equation of the tangent line to the circle at the upper part, we need to find the slope of the tangent line and the coordinates of a point on the circle. The slope of a tangent line to a circle at a given point is the negative reciprocal of the slope of the radius from the center to that point. In this case, the center of the circle is (3, 2) and the radius is 9, so the equation of the circle is (x-3)^2 + (y-2)^2 = 9^2. By differentiating this equation implicitly, we can find the slope of the tangent line.
The equation of the circle is (x-3)^2 + (y-2)^2 = 81.
Differentiating implicitly with respect to x:
2(x-3) + 2(y-2) dy/dx = 0
Simplifying:
(x-3) + (y-2) dy/dx = 0
(y-2) dy/dx = 3-x
dy/dx = (3-x) / (y-2)
To find the slope of the tangent line at the upper part of the circle, we substitute y = 2 + sqrt(81 - (x-3)^2) into the derived equation of dy/dx. After simplifying, we can substitute the coordinates of a point on the circle to find the specific equation of the tangent line.
For r = 9 and x = 3, the specific equation of the tangent line is y = 9 + 3x.
To make a plot of the circle and the tangent line, we graph both the circle equation and the tangent line equation using a software like Matlab or a graphing calculator.

If you drive for 2 hours, at 60 miles per hour, you will have traveled 120 miles. this is a very common type of calculation, involving three quantities: distance, rate and time. if you know just two of these three quantities, you can always calculate the third. thus, if you want to know how much time it is going to take you to get somewhere, and you know that the distance is 120 miles and you will drive at a rate of 60 miles per hour, you can divide the 120 miles by the 60 miles per hour and obtain a time of 2 hours.

An important part of customer service responsibilities of a cable company relates to the speed with which trouble in service can be repaired. Historically, the data show that the likelihood is 0.75 that troubles in a residential service can be repaired on the same day. For the first 5 troubles reported on a given day, what is the probability that fewer than 2 troubles will be repaired on the same day?
Answer:
The probability that fewer than 2 troubles will be repaired on the same day is:
0.015576
Step-by-step explanation:
We have to use the Binomial function is n=order to calculate the probability of r successes out of the n-events.
We know that the probability of r success out of the n-events is given by:
[tex]P(X=r\ successes)=n_C_r\cdot p^r\cdot (1-p)^{n-r}[/tex]
where p is the probability of an success.
Here we have:
n=5 and r=0,1.
since we are asked to find the probability that fewer than 2 troubles will be repaired on the same day.
i.e we have to find:
[tex]P(X<2)=P(X=0)+P(X=1)[/tex]
Also p=0.75 ( since, likelihood is 0.75 that troubles in a residential service can be repaired on the same day )
Hence,
[tex]P(X=0)=5_C_0\cdot (0.75)^{0}\cdot (1-0.75)^{5-0}\\\\P(X=0)=1\cdot 1\cdot (0.25)^5\\\\P(X=0)=0.000976[/tex]
and
[tex]P(X=1)=5_C_1\cdot (0.75)^{1}\cdot (0.25)^{5-1}\\\\P(X=1)=5\cdot (0.75)\cdot (0.25)^4\\\\P(X=1)=0.0146[/tex]
Hence,
[tex]P(X<2)=0.000976+0.0146\\\\P(X<2)=0.015576[/tex]
Hence, the probability that fewer than 2 troubles will be repaired on the same day is:
0.015576
