Simplify the expression
4+ x/2
Answer:
Option (a)
Step-by-step explanation:
The given equation is
y = 4 (2ˣ)
To find y-intercept, substitute x=0 in the equation.
y = 4 (2⁰) = 4 (1) =4
Hence y-intercept is 4.
Since y-intercept is 4, the equation should pass through the point (0,4).
The only graph passing through the point (0,4) is the graph in option (a).
Hence the answer is option (a).
Answer:
The lawyer will have to pay $9541.57 in income tax
Step-by-step explanation:
multiply 173,483 by .055
to get 9,541.57
Answer:
The function is
Step-by-step explanation:
The table representing balance in the account is presented as follows;
Year t
0 100
1 125
2 156.25
3 195.31
4 244.14
5 305.18
The given exponential relationship is y = a·b^t
When t = 0, y = 100
We get; 100 = a·b⁰ = a·1
∴ a = 100
When t = 1, y = 125
We get;
125 = 100·b¹
∴ b = 125/100 = 1.25
The function that represent 'y' (in dollars) after 't' years is y = 100×1.25^t
