Answer:
20.6 cm (im pretty sure lol)
Step-by-step explanation:
sine rule:
(ab = x)
13.5/sin41 = x/sin90
13.5sin90/sin41 = x
x = 20.57741667
ab = 20.6cm
Answer:
123.94
Step-by-step explanation:
Step-by-step explanation:
4x2+8x−3=0
For this equation: a=4, b=8, c=-3
4x2+8x+−3=0
Step 1: Use quadratic formula with a=4, b=8, c=-3.
x=
−b±√b2−4ac
2a
x= −(8)±√(8)2−4(4)(−3)
2(4)
x= −8±√112
8 x=−1+
1 2 √7 or x=−1+
−1 2 √7
Answer: x=−1+
1 2√7 or x=−1+
−1 2 √7
1995. 164 million
2001. 169 million
t = 2001 - 1995 = 6
169 =
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) =
f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be
181 million.
