When he was 40 Keefer began investing $150 per month in various securities for his retirement savings. His investments averaged a 4.5% annual rate of return until he retired at age 70. What was the value of Keefer's retirement savings when he retired? Assume monthly compounding of interest.

Answers

At retirement, Keefer will have saved for 30 (that is, 70-40) years.
Monthly saving, P = $150, Annual rate of return, R = 4.5% = 0.045.

Therefore, future value (FV) at the time of retirement will be;

FV = P*[1+(R/12)^12*30]/(R/12)
Substituting all the parameters;
FV = 150*[1+(1+0.045/12)^360]/(0.045/12) = $113.907.92

write an equation of an ellipse in standard form with the center at the origin and a height of 3 units and width of 1 unit

Answers

Final answer:

The equation of an ellipse with the specified attributes, using the center as the origin, is x2/0.25 + y2/2.25 = 1.

Explanation:

The question asks for the equation of an ellipse with the center at the origin and a height of 3 units and width of 1 unit. In an ellipse, the center is the midpoint of both the major and minor axes. The major axis can be the horizontal (width) or vertical (height) axis, and the minor axis is the other one.

Given that the height of the ellipse is 3 units, this determines the major axis and its length of 2a=3, which means a=1.5. The width of the ellipse is 1 unit, this determines the minor axis and its length of 2b=1, which means b=0.5.

Using these values, the equation of such an ellipse, centered at the origin, in standard form is x2/0.25 + y2/2.25 = 1

The angle of elevation to the top of a building in chicago is found to be 11◦ from the ground at a distance of 1000 feet from the base of the building. find the height of the building.

Answers

The height is 1943.8 feet. easiest way to do this is draw a little diagram. Draw the building and the unknown height can be "x". We know a 1000 feet away from the base of the building, the angle between the ground and top of the building is 11 degrees. If you draw this, you can see that you can use the tan function to find the missing "x". tan (angle) = opposite side/adjacent side. So tan(11) = x/1000. Isolate for x and you get 1943.8 feet

Answer:

The point-slope form of the equation is y - 6 = 4/3(x + 4), which is answer B.

Step-by-step explanation:

In order to find the point-slope form of any equation, start with the base form of the equation.

y - y1 = m(x - x1)

Now input the slope given as m, and the point in for x1 and y1.

y - y1 = m(x - x1)

y - 6 = 4/3(x - -4)

y - 6 = 4/3(x + 4)

how do I solve (x-5)(x-1)=0

Answers

With this equation, you'd distribute one set of parenthesis into the other. Doing so you'd get "X^2 - 1x - 5x + 5 = 0". Simplified, you'd have "X^2 - 6x + 5 = 0"

Next, you'd find the factors of 5, that when multiplied equal 5, and when added, equal -6. Being that 5 is a prime number (a number that is only divisible by 1 and itself) those numbers are 1 and 5. Both numbers have to be negative, in order to get -6.

-1*-5 = 5
-1 + -5 = -6

Finally you split up the X^2 to a single x with each of the factors and make it equal to zero (X - 1 = 0) and (X - 5 = 0). Then you solve each.

(X - 1 = 0) Add 1 to each side. X = 1
(X - 5 = 0) Add 5 to each side. X = 5

A shell fits into a golden rectangle with a length of 8 in. What is the shell's width? write your answer is simplified radical form and rounded to the nearest tenth of an inch.
Select one:
a. About 4.9 inches
b. About 4.1 inches
c. About 5.3 inches

Answers

For this case we have the following relationship:
 l / w = (1 + root (5)) / 2
 Where,
 l: length of the rectangle
 w: width of the rectangle
 Clearing the width we have:
 w = (2 / (1 + root (5))) * (l)
 Substituting values:
 w = (2 / (1 + root (5))) * (8)
 Rewriting:
 w = 4.94427191 inches
 Rounding off we have:
 w = 4.9 inches
 Answer:
 the shell's width is:
 w = 4.9 inches
 a. About 4.9 inches

The correct answer is option(a) about 4.9 inches.

To find the width of a golden rectangle with a given length,  we will use the golden ratio formula  that is

l / w = (1 + √5) / 2

Where, l = length of rectangle &  w = width of rectangle

By applying the above formula we get  the golden ratio, which is ≈ 1.618.

The formula for a golden rectangle is length(l) = 1.618 × width.

Given that length is 8 inches, we set up the equation:

8 = 1.618 × width

Solving for width:

width = 8 / 1.618 = 4.948...

The simplified radical form of 4.948... is ≈ 4.9 inches.

Thus, the correct answer is about 4.9 inches or option (a).

How do you use properties of exponents and logarithms to rewrite functions in equivalent forms and solve equations?

Answers

Some of the logarithmic properties most used to solve equations are the following.
 1) log (a) ^ b = b * log (a)
 2) log (a * b) = log (a) + log (b)
 3) log (a / b) = log (a) - log (b)
 These logarithmic properties can be used to solve equations.
 For example:
 2 ^ x = 56
 If we apply to this equation the logarithm function on both sides that we have left
 log (2) ^ x = log (56)
 This function is equivalent to the first.
 If we now apply the property 1) of the previous logarithms, we can reveal x of the equation.
 x * log (2) = log (56)
 x = log (56) / log (2)
 x = 5,807
 Thus, thanks to the properties of the logarithms, this exponential function could be solved

Final answer:

To use properties of exponents and logarithms effectively, one must apply specific rules such as the logarithm of a product being the sum of the logarithms and the logarithm of a number raised to an exponent being the product of the exponent and the logarithm. Log transformations help linearize and solve equations involving exponents.

Explanation:

To rewrite functions in equivalent forms and solve equations using the properties of exponents and logarithms, one must understand several key rules and relationships. For example, the common logarithm (log) indicates the power to which 10 must be raised to equal a given number.

Two essential properties we use are:

The logarithm of a product of two numbers is the sum of the logarithms of the two numbers (log xy = log x + log y).The logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number (log x^n = n log x).

Exponential and logarithmic functions are inverses. This relationship allows us to simplify complex expressions and solve exponential equations by taking the logarithm of both sides. For instance, the natural logarithm (ln or loge) and the base e exponential are inverse functions, so ln (e^x) = x and e^(ln x) = x.

A log transformation can linearize functions that involve an exponent by taking the log of both sides of the equation. This technique is valuable in solving equations where the variable is an exponent.

A car is traveling at a speed of 50 miles per hour. Each wheel of the car makes 770 revolutions per minute. To the nearest tenth of an inch, what is the diameter of each car wheel? (Note: 1 mile = 5,280 feet)

Answers

Answer: 21.8 inches

Given:

A car is traveling at a speed of 50 miles per hour. Each wheel of the car makes 770 revolutions per minute.

To get the diameter of each car wheel

Get first the length of revolution (circumference of the wheel) in inches.

Speed=50 miles/hr

=50miles/60 minutes

= 0.833333 miles/minute

=.833/5280=4400ft= 52,800 inches/minute

Since there are 770 revolutions per minute, per revolution  (circumference of the wheel) =

=52,800/770

=68.57 inches

Answer:

The equation is [tex]y ^ 2 = \frac{x + 1}{2}[/tex]

The parameter that we have is t. We want to eliminate this parameter in both equations, therefore in the first equation we solve for t and in the second equation we solve for the variable t.

We have:

[tex]x = 2t-1\\\\x + 1 = 2t\\\\t = \frac{x + 1}{2}[/tex]

Now we solve the other equation for t.

[tex]y= \sqrt{t}[/tex]
