Silvia wants to retire at 65 and live on $40,000 a year. How much does she need to save to ensure that her retirement funds last until she is 85?
Select the best answer from the choices provided.
$800,000 because she will need to save for 20 years times $40,000
more than $800,000 because taxes and inflation will increase the value of her savings
less than $800,000 because returns will continue to increase the amount in her savings even after retirement
more than $800,000 because compound return will reduce her savings
Answers
Answer:
$800,000 because she will need to save for 20 years times $40,000
Step-by-step explanation:
Silvia wants to retire at 65 and live on $40,000 a year.
She wants to live till 85 and retire at 65 years.
So, number of years to save = [tex]85 -65= 20[/tex]
And she needs to save [tex]40000\times20=800000[/tex]
Hence, she must save 800,000.

where [tex]x[/tex] lies in what you might call the "principal branch". That is, [tex]\arctan x[/tex] is bounded below by [tex]-\dfrac\pi2[/tex] and above by [tex]\dfrac\pi2[/tex], so it's only a valid inverse of [tex]\tan x[/tex] if we restrict the domain of [tex]\tan x[/tex] to [tex]-\dfrac\pi2<x<\dfrac\pi2[/tex].
In other words, [tex]x[/tex] is some angle whose terminus lies in either the first or fourth quadrant (I'm assuming you're at least a little familiar with the typical unit circle diagrams used in trig). The only value of [tex]x[/tex] in this domain that satisfies the equation above is [tex]x=-\dfrac\pi3[/tex].
On the other hand, [tex]\mathrm{Arctan}(-\sqrt 3)[/tex] captures all possible values of [tex]x[/tex] that satisfy
[tex]\tan x=-\sqrt3[/tex]
First, we know that [tex]\tan(x+\pi)=\tan x[/tex] (in other words, [tex]\tan[/tex] has a period of [tex]\pi[/tex]), so in fact [tex]\tan(x+2\pi)=\tan(x-2\pi)=\cdots=\tan x[/tex] as well. In general, then, we know that [tex]x+n\pi[/tex] will be a valid solution to the equation above, where [tex]n[/tex] is any integer.
Earlier we found that [tex]\arctan(-\sqrt3)=-\dfrac\pi3[/tex], so in this case, [tex]\mathrm{Arctan}(-\sqrt3)=-\dfrac\pi3+n\pi[/tex] for [tex]n\in\mathbb Z[/tex].

At a high school 7 student volunteer for a committtee how many different 5 person committees can be chosen
Answers
Number of committee = 5
Number of ways of selecting the committee from the 7 volunteers = 7C5 = 7!/(5!*2!) = 21 ways.
There are 21 ways in which the 5-committee member can be selected from the 7 volunteers.
Using the combination formula, 21 different 5-person committees can be chosen from a group of 7 students.
To determine how many different 5-person committees can be chosen from a group of 7 students, we use the concept of combinations, specifically the combination formula which is defined as:
C(n, k) = n! / [k! * (n - k)!]
where n is the total number of items to choose from, k is the number of items to choose, and the exclamation point represents a factorial, which is the product of all positive integers up to that number.
Applying this to the given problem, we have:
C(7, 5) = 7! / [5! * (7 - 5)!]
This simplifies to:
C(7, 5) = (7 * 6) / (2 * 1)
Therefore, C(7, 5) = 21.
There are 21 different 5-person committees that can be formed from 7 students.
He altitude of a triangle is increasing at a rate of 3000 centimeters/minute while the area of the triangle is increasing at a rate of 3500 square centimeters/minute. at what rate is the base of the triangle changing when the altitude is 10000 centimeters and the area is 89000 square centimeters?
Answers
A = (1/2) * (b) * (h)
Where,
b: base of the triangle
h: height of the triangle
Deriving the area we have:
A '= (1/2) * ((b') * (h) + (b) * (h '))
Clearing b' we have:
b '= (2A' - (b) * (h ')) / (h)
We must look for the value of the base:
A = (1/2) * (b) * (h)
Substituting values:
89000 = (1/2) * (b) * (10000)
b = (89000) / (5000)
b = 17.8 cm
Then, the speed at which the base changes is:
b '= (2 * (3500) - (17.8) * (3000)) / (10000)
b '= -4.64 cm / min
Answer:
The base of the triangle is decreasing at:
4.64 cm / min
The recursive rule for a sequence is shown. an=an−1+7 a1=17 what is the explicit rule for this sequence?
Answers
an=a(n-1)+7; a1=17
to get the explicit formula we proceed as follows:
common difference=7
a1=17
but the explicit formula for arithmetic sequence is:
an=a+(n-1)d
where:
a=fist term
n=number of terms
d=common difference
plugging the values in the formula we get:
an=17+(n-1)7
simplifying we get
an=17+7n-7
an=7n+10
Answer: an=7n+10
The explicit rule for the sequence is [tex]a_n = 10 + 7n[/tex]
The recursive rule is given as:
[tex]a_n=a_{n-1}+7[/tex]
[tex]a_1 = 17[/tex]
The above shows that the sequence is an arithmetic sequence.
Start by calculating a2
We have:
[tex]a_n=a_{n-1}+7[/tex]
Substitute 2 for n
[tex]a_2=a_1+7[/tex]
This gives
[tex]a_2 = 17 + 7[/tex]
[tex]a_2 = 24[/tex]
So, we have:
a1=17
a2 = 24
The common difference (d) is:
d =a2 - a1
d = 24 - 17
d = 7
The explicit rule is then calculated as:
[tex]a_n = a_1 + (n - 1)d[/tex]
This gives
[tex]a_n = 17 + (n - 1) * 7[/tex]
Expand
[tex]a_n = 17 - 7 + 7n[/tex]
[tex]a_n = 10 + 7n[/tex]
Hence, the explicit rule for the sequence is [tex]a_n = 10 + 7n[/tex]

The length of a rectangle is 5 yd less than three times the width, and the area of the rectangle is 28 yd2 . find the dimensions of the rectangle.
Answers
The formula for the area of a rectangle is A = lw. Substitute, so then it's 28 = (3x-5) * x, and you evaluate.
Hope this helps you! And rate so I can see if I did well!
The dimensions of the rectangle are width = 4 yds and length = 7 yds.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that the length of a rectangle is 5 yds less than three times the width,
The area of the rectangle is 28 yds square.
Let the width of the rectangle is x
So the length of the rectangle = 3x - 5
The area of a rectangle = x × (3x - 5)
28 = 3x² - 5x
3x² - 5x - 28 = 0
(3x + 7)(x - 4) = 0
3x + 7 = 0 and and x - 4 = 0
x = -7/3 and x = 4
Take x = 4 as the width
So the length of the rectangle = 3(4) - 5 = 12 - 5 = 7
Therefore, the dimensions of the rectangle are width = 4 yds and length = 7 yds.

Moves object to a distance=9 [tex]f t s[/tex]
Let A and B be the displacements Vectors
A= (0,-5)
B= (6,-2)
To Find:

Solution:
Work done [tex]W=F \times D[/tex]
Direction of force vector= (3,-1) (i, j)

Result:
Work done to move an object [tex]=23.15 \text { foot pounds }[/tex]
Answer:
[tex]W = 25.617\,lbf\cdot ft[/tex]
Step-by-step explanation:
The work done to move the object is:
[tex]W = F \cdot s \cdot \cos \alpha[/tex]
The angle of the force with respect to change in the position vector is:
[tex]\alpha = \tan^{-1}\left(-\frac{7}{6} \right) - \tan^{-1}\left(-\frac{1}{3} \right)[/tex]
[tex]\alpha \approx 18.415^{\textdegree}[/tex]
The magnitude of the work done is:
[tex]W = (3\,lbf)\cdot (9\,ft)\cdot \cos 18.415^{\textdegree}[/tex]
[tex]W = 25.617\,lbf\cdot ft[/tex]
