Answer:
<h2>823.7 m²</h2>
Step-by-step explanation:
If a figure A and a figure B are similar, then
(*)
<em>k</em><em> - similarity scale</em>
<em />
Calculate the similarity scale:
We have the surface area of the smaller prism 572 m².
Substitute to the formula (*):
Answer:
√6 + √2
= --------------

Step-by-step explanation:
15° = 45° - 30°
So
cos(15) = cos(45 - 30)
=cos(45) × cos(30) + sin(45) × sin(30)
= 1/√2 × (√3)/2 + 1/√2 × 1/2
(√3) + 1
= --------------
2√2
(√3) + 1 √2
= -------------- x ---------
2√2 √2
√6 + √2
= --------------

Answer: 3log5(2) - 1 or ~0,29203
Step-by-step explanation:
2log5(4) - log5(10)
log5(4^2) - log5(10)
log5(4^2/10)
log5(16/10)
log5(8/5)
Log5(8) - log5(5)
log5(2^3) - 1
3log5(2) - 1
The positive integers would be 8 and 9
because 8*9= 72
