Answer:
8n - 4
Step-by-step explanation:
The numbers here go up in 8, so you have 8n. Afterwards, use the term and the 8 times tables. Eg. 4 is the first term and the first 8 multiple is 8, so 4-8. You have to subtract 4 from 8 to get the first term. Sorry if this didn't help but yeah...
Answer:
∡ZA = 66°
Step-by-step explanation:
Suplementary angles sum 180°
ZA + ZB = 180°
then:
(2x - 14)° + (3x-6)° = 180°
2x + 3x - 14 - 6 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40
then:
∡ZA = (2x - 14)
∡ZA = (2*40 - 14)
∡ZA = (80-14)
∡ZA = 66°

Answer:
1
Step-by-step explanation:
f(x) = x^2 - 2x - 4
when x = -1, f(-1) = (-1)^2 - 2(-1) - 4 = 1 + 2 - 4 = -1
when x = 4, f(4) = (4)^2 - 2(4) - 4 = 16 - 8 - 4 = 4
The average rate of change from x = -1 to x = 4:
f(4) - f(-1) 4 - (-1) 5
---------------- = -----------------= -------- = 1
x4 - x1 4 - (-1) 5
Answer
The average rate of change = 1
The population will reach 540 000 in 30.8 yr.
The formula for population growth is
<em>P</em>_<em>t</em> = <em>P</em>_0 × e^(<em>rt</em>)
540 000 = 270 000 × e^(0.0225t)
e^(0.0225t) = 2
0.0225t = ln2
t = (ln2)/0.0225 = 30.8
