Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
, where
- <em>A</em> is the new value
- <em>P</em> is the original value
- <em>r</em> is the rate in decimal
- <em>t</em> is the time in years
∵ Dan buys a car for £2700
∴ <em>P</em> = 2700
∵ It depreciates at a rate of 1.4% per year
∴ <em>r</em> = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ <em>t</em> = 5
→ Substitute all of these values in the rule above to find A
∵ 
→ Use your calculator to find the answer
∴ <em>A</em> = 2516.22
∴ The car will be worth £2516.22 in 5 years
Y(y+21) If you think about it you will see that it would most likely be this answer because the product of something is multiplying, and the sum is adding. If this answer is not correct then I am sorry.
No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.
We find that the lcm ( lowest common denominator ) is 20.
1 x 5 = 5
4 x 5 = 20
2 x 4 = 8
5 x 4 = 20.
so the answer is no.
Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x + 10 = 0 ( subtract 10 from both sides )
x² - 8x = - 10
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 10 + 16
(x - 4)² = 6 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact solutions
