Answer:

Rational

Step-by-step explanation:

To find out whether it is rational or irrational let's write the definitions of both

Rational: Any number that can be written as a fraction, integer, whole number, natural number

Irrational: Numbers that can't be written as a fraction

This has to be rational because every rational number can be written as a repeating decimal.

Since it can be expressed as fraction, it's a rational number.

Sarah invested £12000 in a unit trust 5 years ago, the value of the unit trust increased by 7% per annum for each of the last 3
trasher [3.6K]

Answer:

The current price of the unit trust =  £13,831.72

Step-by-step explanation:

Since it increased 7% per annum in last three years and decreased by 3% per annum before that, it implies that the unit trust decreased by 3% per annum for the first 2 years and then increased by 7% per annum for the next 3 years in the total 5 year period

The invested after 2 years = 12,000*(1-0.03)^2 = £11,290.8

This amount then grows by 7% for the next 3 years making it = 11,290.80*(1+0.07)^3 =  £13,831.7155 = £13,831.72 (Rounded to 2 decimals)

The current price of the unit trust =  £13,831.72 (Rounded to 2 decimals)

My name is Ann [436]

Answer:

v = \dfrac{8}{a(y - 7)}

Step-by-step explanation:

y = \dfrac{8}{av} + 7

Subtract 7 from both sides.

y - 7 = \dfrac{8}{av}

Multiply both sides by v.

v(y - 7) = \dfrac{8}{a}

Multiply both sides by 1/(y - 7).

v = \dfrac{8}{a(y - 7)}
