The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Answers
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.

A tree measured 12 1/2
feet tall. Over the next 5 1/2
years it grew to be 51 feet tall.
During the 5 1/2
years, what was the average yearly growth rate of the tree?
Answers
Answer:4.08 ft a year or 1 and 5/8 feet a year (approx)
Step-by-step explanation:
It's 12.5 feet the first year
51 feet 5 years later
If you do the math and divide 51 by 12.5, you get 4.08 which is around 1 and 5/8 ft
12.5x4.08 is 51 feet.
So the tree grows approximately 1 and 5/8 feet a year

$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answers
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140

How many radians is 252°?
Give the exact answer in simplest form
Answers
Radian is a more advanced degrees measurement that is easier to use in trigonometry physics etc.
A full circle 360 degrees is 2pi radian.
We just need to find the ratio of 252 degrees to 360 degrees and multiply that by 2pi.
252/360*2pi(rad)
=126/180*2pi(rad)
=63/90*2pi(rad)
=21/30*2pi(rad)
=7/10*2pi(rad)
=7/5*pi (Radian)
