7. In 2009, the national average price for milk was $3.11
and in 2011 it rose again to $3.57 per gallon.
Was the percent increase in cost greater from 2009
your answer.
Answers
The percentage increase in cost greater from 2009 is 14.79%
The average price of milk in 2009 = $3.11
The average of price of milk in 2011 = $3.57
The increase in price = The average of price of milk in 2011 - The average price of milk in 2009
Substitute the values in the equation
The increase in price = 3.57 - 3.11
= $0.46
The percentage increase = The increase in price / The average price of milk in 2009 × 100
Substitute the values in the equation
The percentage increase = ( 0.46 / 3.11 )×100
= 14.79%
Hence, the percentage increase in cost greater from 2009 is 14.79%

Rewrite the function by completing the square. h ( x ) = x 2 + 3 x − 18 h(x)=x 2 +3x−18
Answers
The quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.
We are given a quadratic function:
h (x) = x^2 + 3x − 18
We need to rewrite the function by completing the square.
We can see the coefficient of x is 3.
So, we will add and subtract the square of half that.
So, find the square of half of 3, we will get;
(3 / 2)^2 = 9 / 4 = 2.25
add and subtract the square of half of 3 from the given function, we will get;
h(x) = x^2 +3x + -18 2.25 -2.25
arrange the expression, we will get;
h(x) = (x^2 +3x +2.25) -18 -2.25
write the expression in parentheses as a square, and simplify the constant, we will get;
h(x) = (x + 1.5)^2 - 20.25
So, the square function is written as h(x) = (x + 1.5)^2 - 20.25.
Thus, the quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.

Answers
It will take 37.5 years.
From the question, we have
A_0 = 8 billion
A = 9 billion.
r= 3% per year
A = A_0*e^rt
9 = 8*e^3t/100
9/8 = e^3t/100
Taking log_e both sides,
log_e 9/8 = log_e e^3t/100
9/8 = 3t/100
t = (9*100)/(8*3)
t = 37.5 years

Membership costs for belonging to a gym for a certain number of months are shown in the table below.
Answers
Answer:
y = 35.5x - 10
Step-by-step explanation:
If we graph the function with the help of the given table,
Since, there is a common difference in each term of 'cost of gym membership'
d = 61 - 25.5 = 35.5
d = 96.5 - 61 = 35.5
Graph will represent a linear function.
Let the equation of the line is,
y - y' = m(x - x')
where (x', y') is a point lying on the graph and 'm' is the slope.
Two points lying on the graph are (1, 25.5) and (2, 61).
Slope of the line =
=
= 35.5
Equation of the line passing through (1, 25.5) having slope 'm' = 35.5
y - 25.5 = 35.5(x - 1)
y = 35.5x - 35.5 + 25.5
y = 35.5x - 10
Here x = duration of membership
y = membership price
Therefore, equation representing Fit Zoom's membership price equation will be,
y = 35.5x - 10

Answers
There is not any chance of getting negative number in answer.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
f(x) = 5
Here, f(x) = 5 shows that whatever is the value of x the result value will be 5.
As, there is no variable x in the defined function and only having a constant 5 which is positive in nature.
So, whatever be the value of x is we will get 5 only.
Thus, there is not any chance of getting negative number in answer.

Answers
The amount owed at the end of 1 year is $4120 and by the end of 2 years, $4243.60 when Tom borrows $4000 at an interest rate of 3% compounded each year.
What is compound interest?The interest you earn on interest is known as compound interest. Simple math can be used to demonstrate this: if you have $100 and it earns 5% interest annually, you will have $105 at the end of the first year. You will end up with $110.25 at the end of the second year. In order to calculate compound interest, multiply the principal of the original loan by the annual interest rate multiplied by the number of compound periods minus one.
Here,
principle amount=$4000
rate of interest=3%
For first year,
A=P(1+r/n)^(nt)
A=4000(1+3/12)^12*1
A=$4,120.00
For first year,
A=P(1+r/n)^(nt)
A=4120(1+3/12)^12*1
A=$4,243.60
When Tom borrows $4000 at an interest rate of 3% compounded annually, the total amount due at the end of one year is $4120, and at the end of two years, it is $4243.60.

300 metros = 300/1000 = 0.3 kilómetros
Entonces:
300 metros por minuto = 300metros/minuto
300 metros / minuto = 0.3kilómetros / 0.01667 horas
