Answer:
20cm, 28cm, 40cm
Step-by-step explanation:
Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.
4x + 7x + 10x = 105
21x = 105
x = 105 ÷ 21
x = 5
Shortest side (4x) = 5 × 4
Shortest side (4x) = 20
Middle side (7x) = 7 × 4
Middle side (7x) = 28
Longest side (10x) = 10 × 4
Longest side (10x) = 40
Two million, nine thousand three hundred forty five
Answer: 1/2
Step-by-step explanation:
Circumference is equal to 2πr. Now, if the circumference itself is equal to pi, then the equation becomes the following:
π = 2πr
Divide both sides by pi:
1 = 2r
Divide both sides by 2:
r = 1/2
Answer:
There is a hole at x = 3 and an asymptote at x = –1.
Step-by-step explanation:
f(x) = (x-3)/(x²-2x-3)
f(x) = (x-3)/(x-3)(x+1) = 1 / x+1 (x=3 is a hole)
asymptote while x+1 --> 0 and f(x) -->∞
x = -1 is vertical asymptote
