Answer:
61
Step-by-step explanation:
So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below
Answer:
22.36
Step-by-step explanation:
if you drop the radius to less than that, then the Area will also drop to less than 1 unit, in this case it happens to be a decimeter
Answer:
77.25 cm^2
Step-by-step explanation:
Area of a regular octagon :
2a^2(1 + (sqrt2))
where a is the side
substitute 4 in for 'a'
Answer: center (1;0), radius = 2
Step-by-step explanation:
x² – 2x + 5+ y² = 8
x² – 2x + 5+ y² = x² – 2x + 1 + 4 + y² = (х-1)² +4 + y²
(х-1)² +4 + y² = 8
(х-1)² + y² = 8 - 4 = 4
(х-1)² + y² = 2²
center (1;0), radius = 2
