Answer:

17. a)

Step-by-step explanation:

17.

f(x) =x/2, then f(x-3)=(x-3)/2

x=3, f(x-3)=f(3-3)=f(0)=0 (values in table)

f(x-3)+3=0+3=3

18.

f(x) =x/2

f(x-2) for x=5 is f(5-2)=f(3)=3/2

f(x-2)+5=f(3)+5=3/2+5=3/2+10/2=13/2

In 2010, the population of a city was 161,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 6.7%.
solniwko [45]

Answer:

99%

Step-by-step explanation:

2010 population = 161,000

From 2010 to 2015, the population grew by 8%.

2010 to 2015 = 161,000 + (8% of 161,000)

= 161,000 + (0.08 * 161,000)

= 161,000 + 12,880

= 173,880

2010 to 2015 = 173,880

From 2015 to 2020, it fell by 6.7%

2015 to 2020 = 173,880 - (6.7% of 173,880)

= 173,880 - (0.067 * 173,880)

= 173,880 - 11,649.96

= 162,230.04

2015 to 2020 = 162,230.04

what percent did the city grow from 2010 to 2020.

= 161,000 / 162,230.04 × 100

= 0.9924179270374 × 100

= 99.241792703743

Approximately, 99% to the nearest whole number

Simplify, thank you in advance

\bf \cfrac{3}{x+4}+\cfrac{2}{x^2-16}\implies \cfrac{3}{x+4}+\cfrac{2}{\stackrel{\textit{difference of squares}}{x^2-4^2}}\implies \cfrac{3}{x+4}+\cfrac{2}{(x-4)(x+4)}\\\\\\\stackrel{\textit{so our LCD will be }(x-4)(x+4)}{\cfrac{(x-4)3+(1)2}{(x-4)(x+4)}}\implies \cfrac{3x-12+2}{(x-4)(x+4)}\implies \cfrac{3x-10}{(x-4)(x+4)}
