No it is not an arithmetic sequence
F(x)= 0.02x^2 + 0.08x + 30.6
so for f(0) all that means is where you see x plug 0 for x..
f(0)= 0.02(0)^2+ 0.08(0) + 30.6
f(0)= 30.6
f(4)= 0.02(4)^2 + 0.08(4) + 30.6
f(10)= 0.02(10)^2 + 0.08(10) + 30.6
attached are calculated answers
Step-by-step explanation:
sofia mother-- 12+2a
sofia-- 2a
after 8years
sofia mother (2a×3) - 20
sofia 2a+8
solution
(2a×3) - 20) + 2a = (12+2a) + (2a+8)
(6a-20) + 2a = 12+2a+2a+8
6a-20+2a = 4a + 20
8a-20= 4a+20
collect like terms
8a-4a= 20+20
4a=40
divide both side by 4
a= 10
present age
sofia mother= 12+2a
12+2(10)
=12+20
= 32
sofia age= 2a
= 2(10)
= 20
Sofia mother present age is 32
sofia present age is 20
Answer: x<2
Step-by-step explanation:
9(2+3x)<72
2+3x<72/9
2+3x<8
3x<8−2
3x<6
x<6/3
x<2
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
