Answer:
The correct option is B) £2621440.
Step-by-step explanation:
Consider the provided information.
Contestants are asked a number of questions; they get £5 if they only answer one question correctly, £10 if they answer two questions correctly, £20 if they answer three questions correctly and so on.
This form a G.P
5, 10, 20, 40.....
The nth term of a GP series is
Where a₁ is the first term and r is the common ratio.
Here the first term is 5 and we need to find the value of 20th term.
The common ratio is:
Substitute the respective values in the above formula.
Hence, the correct option is B) £2621440.
The answer is (2, 14) because if you substitute the x and y values, it would have to be 2 + 7 = 14.
Answer:
D. y = 6x
Step-by-step explanation:
y intercept B is zero
slope A is Δy/Δx = (12 - 6) / 2 - 1) = 6
y = Ax + B
y = 6x + 0
y = 6x
Unit rate of change is 60, because he's paid 60 dollars an hour. This is found by dividing his profit by hours worked, so for example on day one he worked 5 hours and received 300 dollars. 300/5=60. The equation for the graph would be y=60x [money paid = $60 x (hours)]
