Answer: He pays £4500 as tax.

Step-by-step explanation:

Given: John's earnings before tax = £38000 >  £20000

Money over  £20000 =  £38000  - £20000 = £18000

Tax amount = 25% of money over  £20000

⇒Tax amount= 0.25 x (18000 )   [25% = 0.25]

⇒Tax amount=  £ 4500

Hence, he pays £4500 as tax.

9375 grams of radioactive material decays every hour in a geometric fashion. After 4 hours of decay, 15 grams of radioactive mat
Paladinen [302]

The amount of radioactive material that would remain by the 7th hour of decay is 0.12 grams.

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where y,x are variables, a is the initial value and b is the multiplicative factor.

Let y represent the amount of substance remaining after x hours. Hence:

a = 9375, at x = 4, y = 15:

15 = 9375(b)⁴

b = 0.2

y = 9375(0.2)ˣ

For the 7th hour, x = 7:

y = 9375(0.2)⁷ = 0.12

The amount of radioactive material that would remain by the 7th hour of decay is 0.12 grams.
