Siân is saving for a car which costs 11 800 AUD. Find how many years it will take for the value of the investment to reach this value. Round to the nearest year.
Answer:
See explanation
Step-by-step explanation:
The question is incomplete as the invested amount and the interest rate are not given. However, I will give a general method of solving it.
Assume that:
[tex]r = 5\%[/tex] --- interest rate
[tex]PV =9000[/tex] --- Present value or invested amount
To calculate time (in years), we make use of the following formula of future value
[tex]FV = PV(1 + r)^n[/tex]
Where
[tex]FV = 11800[/tex]
So:
[tex]11800 = 9000( 1 + 5\%)^n[/tex]
Divide both sides by 9000
[tex]1.31 = ( 1 + 5\%)^n[/tex]
Take logarithm of both sides
[tex]Log(1.31) = Log(1 + 5\%)^n[/tex]
Apply law of logarithm
[tex]Log(1.31) = nLog(1 + 5\%)[/tex]
Make n the subject
[tex]n = \frac{Log(1.31)}{Log(1 + 5\%)}[/tex]
Express 5% as decimal
[tex]n = \frac{Log(1.31)}{Log(1 + 0.05)}[/tex]
[tex]n = \frac{Log(1.31)}{Log(1.05)}[/tex]
[tex]n = \frac{0.1173}{0.0212}[/tex]
[tex]n \approx 6[/tex]
The time to reach the future value is approximately 6 years.

An economist calculates that the cost of living in Westminster is currently $44,000 per year and is increasing by 5% per year. What will the cost of living be in 20 years? Round to the nearest cent.
Given:
Initial cost of living = $44,000
Rate of increase = 5% = 0.05
To find:
The cost of living in 20 years.
Solution:
The exponential growth model is:
[tex]y=a(1+r)^t[/tex]
Where, a is the initial value, r is the growth rate and t is the number of years.
Putting [tex]a=44000,r=0.05, t=20[/tex] in the above model, we get
[tex]y=44000(1+0.05)^{20}[/tex]
[tex]y=44000(1.05)^{20}[/tex]
[tex]y=116745.099026 [/tex]
[tex]y\approx 116745.10 [/tex]
Therefore, the cost of living in 20 years is about $116745.10.

Insert 3 rational numbers between 1 /4 and 1/3 using mean method
Answer:
13/48, 7/24, and 15/48
Step-by-step explanation:
When we have two numbers A and B (such that A < B), the mean between these numbers is:
mean = (A + B)/2
And we will always have that:
A < mean < B
In this case, we have the numbers 1/4 and 1/3
The mean between these numbers is:
M = (1/4 + 1/3)/2 = (3/12 + 4/12)/2 = (7/12)/2 = 7/24
we know that 7/24 is an integer that is between the numbers 1/4 and 1/3
Now we can take the mean between 1/4 and 7/24
M = (1/4 + 7/24)/2
= (6/24 + 7/24)/2 = (13/24)/2 = 13/48
And we have:
1/4 < 13/48 < 7/24
Now we can find the mean between 7/24 and 1/3:
M = ( 7/24 + 1/3)/2 = (7/24 + 8/24)/2 = (15/24)/2 = 15/48
then:
7/24 < 15/48 < 1/3
Then we can write:
1/4 < 13/48 < 7/24 < 15/48 < 1/3
Then the 3 rational numbers between 1/4 and 1/3 are:
13/48, 7/24, and 15/48

the diameter of the circle is 8 ft
what is the approximate area of the circle, in square feet? use 3.14 for π
Answer:
50.24
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Area of a Circle:
A = πr²
Work:
A = πr²
A = 3.14(4²)
A = 3.14(16)
A = 50.24
The approximate area of the circle is 50.24 square feet.
Given is a circle with diameter of 8 ft we need to find the approximate area of the circle.
To find the approximate area of a circle, you can use the formula:
Area = π × (radius)²
Given that the diameter of the circle is 8 ft, we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 8 ft / 2 = 4 ft
Now we can calculate the approximate area:
Area ≈ 3.14 × (4 ft)²
= 3.14 × 16 ft²
≈ 50.24 ft²
Therefore, the approximate area of the circle is 50.24 square feet.

A walking path across a park is represented by the equation y=-4x+10. A new path will be built perpendicular to this path. The paths will intersect at the point (4,-6). Identify the equation that represents the new path. A. y=4x-22 B. y=1/4x-7 C. y=-4x+10 D. y=-1/4x-5
Given:
The equation of a line is
[tex]y=-4x+10[/tex]
A perpendicular line on the given line passes through the point (4,-6).
To find:
The equation of the perpendicular line.
Solution:
We have,
[tex]y=-4x+10[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=-4[/tex]
So, the slope of the given line is -4.
We know that the product of slopes of two perpendicular lines is always -1.
[tex]m\times m_1=-1[/tex]
[tex](-4)\times m_1=-1[/tex]
[tex]m_1=\dfrac{-1}{-4}[/tex]
[tex]m_1=\dfrac{1}{4}[/tex]
The slope of the required line is [tex]\dfrac{1}{4}[/tex] and it passes through the point (4,-6). So, the equation of the line is
[tex]y-y_1=m_1(x-x_1)[/tex]
[tex]y-(-6)=\dfrac{1}{4}(x-4)[/tex]
[tex]y+6=\dfrac{1}{4}x-1[/tex]
[tex]y=\dfrac{1}{4}x-1-6[/tex]
[tex]y=\dfrac{1}{4}x-7[/tex]
Therefore, the correct option is B.
