Answer:
19.3 m²
Steps:
Area of octagon : 2 ( 1 + √2 ) * a² ........ <u>where a is length of each side</u>
using the formula: 2 ( 1 + √2 ) * 2²
: 2 ( 1 + √2 ) * 4
: ( 8 + 8√2 ) m²
: 19.3 m² ...............our final answer in three significant fig
Answer:
Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also ... Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without ... This is because there are two special triangles whose side ratios we know!

Answer:
24 years
Step-by-step explanation:
Total = start*(1 + interest rate / amount of times compounded per month)^(years*amount of compounds per year)
6000 = 3000*(1+0.03/4)^(4x)
6000 = 3000* ((403/400)^4)^x
2 = ((403/400)^4)^x
x = log base-((403/400)^4) of 2 = x
x = 23.19
rounding down 23 years (but you probably want a year over that to get at least 6000, so 24)
Answer:
6
Step-by-step explanation:
