Each with 220 sides,meaning 440 edges on the end
According to Wikipedia, "the domain... is the set of "input"... for which the function is defined."
This essentially means the domain is where there is a 'definition' or y value for a function.
For this equation the only y value possible is 0 so the domain is 0 or optionally written as [0,0]
Answer:
1.) 3/4
2.) 44/5 or 8 4/5
3.) 17/6 or 2 5/6
Step-by-step explanation:
1.) 5/16 ÷ 5/12
To divide a fraction by another fraction, reciprocate (put the numerator to denominator and vice versa) the divisor then change the sign to multiplication:
5/16 × 12/5
5 × 12 / 16 × 5
Cancel out 5 since both numerator and denominator has it:
12 / 16
Divide both by 4:
12 ÷ 4 / 16 ÷ 4
3/4
2.) 3 1/5 • 2 3/4
You have to convert the fractions first to improper fractions by multiplying the denominator to the whole number then adding the numerator to the product:
3 1/5 = 3×5 + 1 = 16/5
2 3/4 = 2 × 4 + 3 = 11/4
Now you can multiply the numerator to numerator then denominator to denominator:
Since 16 is a factor of 4, you can cancel it out, which leaves 4:
16 / 5 × 11/4
4 × 11 / 5 × 1
44/ 5
3.) 6 3/8 ÷ 2 1/4
Convert to improper fraction:
6 3/8 = 6× 8 + 3 = 51/8
2 1/4 = 4 × 2 + 1 = 9/4
(51 × 4)/ (9×8)
51 × 1/ 9× 2
51 / 18
Divide by 3:
17/6
Answer:
40.8 yd
Step-by-step explanation:
From SOH CAH TOA, you know that the relationship between the adjacent side (distance to tower) and opposite side (height of tower) of the relevant triangle is given by ...
... tan(11°) = (height of tower)/(distance to tower)
Multiplying by the denominator, we have ...
... height of tower = (distance to tower) × tan(11°)
... = (210 yd) × 0.19438 ≈ 40.82 yd
Rounded to the nearest 0.1 yd, the height is 40.8 yd.
