Answer:
13%
Step-by-step explanation:
<u>Given:</u>
- MP = 2080
- Discount = d%
- VAT = (d-2)%
- Cost = 1997.84
<u>Apply discount:</u>
- 2080 - d% = 2080*(1 - 0.01d)
<u>Add VAT:</u>
- 2080*(1 - 0.01d) + (d - 2)%
- 2080*(1 - 0.01d) * (1 + (d -2)/100)
- 2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
- (1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
- 0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
- - 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
- 0.0001d²- 0.0002d - 0.0195 = 0
- d² - 2d + 195 = 0
<u>Solving the quadratic equation we get:</u>
<u>Then</u>
Answer:
The common difference is 3
Step-by-step explanation:
we know that
In an <u>Arithmetic Sequence</u> the difference between one term and the next is a constant called the common difference
we have
so
therefore
The common difference is 3
I think the shape is an right angel. And for the answer to h is 90° and i think for b it is 45°. I hope this helps :)
