Answer:
<em>£ 449.20</em>
Step-by-step explanation:
We have to reduce 465.98 by 3.6%
Firstly, lets convert the percentage to decimal by dividing by 100. So we have:
3.6/100 = 0.036
Lets find 3.6% of 465.98
That is:
0.036 * 465.98 = 16.77528
This is the "LESSENED" amount. So the final amount would be:
465.98 - 16.77528 = 449.20472
<em>Rounding to 2 decimal places, £ 449.20</em>
Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
Answer:
Graph D is correct
Step-by-step explanation:
This is complicated because the scales on the x-axis and y-axis are not the same. Graph D has the correct y-intercepts and the correct slopes. The solution is x = 500, where the two lines intersect.
You didn’t post the options but that is also equal to 1.0 x 10^-6
