I will answer second attachment and after since I can't see the firs attachment
2nd attachment
if x is negative, then the first number gets infinitely small
look at the second number, the first 2 is -2 which is wrong since it should be +2
3rd option is not because if x=-2, then y=1
answer is D
3rd attachment
2nd: f(x)=60*1.15^x
3rd: no xint
6th: after 7.86 years value tripples
7th maybe: after 8 years value is 183.51, not exatly 184.00
4th attachment
nth score is
f(n)=57+4(n-1)
9th is
f(9)=57+4(9-1)
57+32=89
answer is C 89
5th
f(t)=23000(1.02)^t
t=time in years from 23000
Answer:
<u>f(f¹(14)) = 134</u>
Step-by-step explanation:
Given :
Find the value of f(14) :
- f(14) = 3(14) + 2
- f(14) = 42 + 2
- f(14) = 44
Therefore, f(f¹(14)) = f(44).
Solving :
- f(44) = 3(44) + 2
- f(44) = 132 + 2
- <u>f(f¹(14)) = 134</u>
The linear equation is “y = 1/4 + 40”.
tan = opposite/adjacent
tan 57° = x/12
Cross multiply.
x = 1.53986496381 * 12
x = 18.5 (rounded to nearest tenth).
