Step-by-step explanation:
the perimeter = 17+19+21+33+27=117 cm
First: f(2) is same as f(x=2) so all we have to do is to express x=2 in f(x)
f(2) = 3*2 + 2 = 8
Second
f^(-1) (3) is inverse function. first we solve f(x) for x.
let f(x) be equal to some variable m
m = (2x -7)/3
3m = 2x - 7
2x = 3m + 7
x = (3m + 7)/3
now we write:
f^-1(x) = (3x + 7)/3
x=3
f^-1(3) = 16/3
Third
2y + 14 = 4y - 2
we just solve for y
2y = 16
y = 8
Now we take that f(x) = y because we both write to be the functions of x
that means that First and third have same result.
74.3 is greater than 7.43
Answer:
, the fourth option.
Step-by-step explanation:
Tan means 
or opposite side divided by adjacent side.
Tan A equals the opposite side of the angle A divided by its adjacent side.
The side opposite of A is y and side adjacent to it is x.
So, Tan A equals !
The total bill paid for a person who uses 600 kWh in a month is $60.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let us assume that the utility company charges $0.10 per kWh, hence:
Total charge in a month = 0.10 * 600 = $60
The total bill paid for a person who uses 600 kWh in a month is $60.
