Answer:

See below

Step-by-step explanation:

20% loss a year with initial value of £6000 can be shown as function:

V(t) = 6000*0.8^t

V(t) - is the value after t years

a) t = 1 year

V(1) = 6000*0.8 = £4800

b) t = 3 years

V(3) = 6000*0.8^3 = £3072

c) t = 8 years

V(8) = 6000*0.8^8 = £1006.63

Step-by-step explanation:

Given

Investment P₀ = $8300
Interest rate r = 6.6%
Compound = continuous
Time t=14 years
P = ?

5. 3x-X-7=3 6.3x-3-X=3 7. -1 - 2x +3x=5 8. 3x - 22 - X=6 9. 2x+3x-10=10

Marta_Voda [28]

** 3x - x -7 = 3

2x = 10

x = 5

** 6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = $\frac{6}{17}$

** 7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** 8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = $\frac{28}{23}$

** 9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

21x = 20

x = $\frac{20}{21}$

Ken’s predicted temperature for April is 7ºC. His prediction for May is 2ºC higher than April. He used the number line to solve

tia_tia [17]

Answer: Ken Should have moved 9 units to the right because his prediction for May is 9°C. Moving to the left part of the number line would take Ken into negative degrees. 9°C is warmer than 7°C. Therefore, Ken should have moved 9 units to the right of the number line instead of 2 units to the left.
