The current price index is mathematically given as,$538.194
What is the current price index?By increasing the ratio of the current value to the reference value by 100, one can determine the index value.
Given that the current cost of gasoline is $3.10 per gallon. we need to find the current price index number, using the 1975 price of 56.7 cents as the reference value.
In regard to this issue, we have that:
Current value = $3.10
Reference value: $0.576
Typically, the mathematical formula for the Index price is,
I = (3.10/0.576) x 100
I= $538.194
The current price index number is 538.194

Roland's farm land is assessed at 1.5 million dollars and the improvements for $500,000.
At a tax rate of 4 mills, how much are Rolan's monthly taxes?
At a tax rate of 4 mills, Rolan's monthly taxes are $667.00.
What is the mill rate?The amount of tax due per $1 of a property's assessed value is known as the mill rate. The word mill comes from the Latin millesimum, which means thousandth. In terms of property tax, 1 mill is the amount of property tax levied per $1,000 of the assessed value of a property. Divide the mill rate by 1,000 and multiply the assessed value of the property to determine the property tax.Given:
Assessed value = 1.5 million dollars
Amount for Improvements = $500,000
Tax rate = 4 mills
Total assessment of the property = Assessed value + Improvements
= 1,500,000 + 500,000
= $2,000,000
Multiply these 2 million by 4 mills then divide by 1000.
(2,000,000 × 4)/1000
= $8000 in annual taxes
To calculate the monthly tax amount divide by 12.
$8000/12 = $667.00

Brandon is trying out for a junior bowling league. He bowled some extra games Friday and Saturday to practice. On Friday, he paid $7 to rent a pair of shoes and x dollars an hour to bowl. He went to a different bowling alley on Saturday, where he paid $5 to rent shoes and y dollars an hour to bowl. Brandon bowled 2 hours on Friday and 3 hours on
Saturday.
The equation for two different bowling alleys is 2x - 3y = -2
This is a problem from algebraic equations. We can solve this problem by following a few steps.
In the first case, he paid $7 to rent a pair of shoes and x dollars an hour to bowl and bowled for 2 hours on Friday.
Here, the cost to bowl for one hour is x dollars. So, the cost to bowl for 2 hours is ( 2× x ) = 2x
Now, the total expenditure for shoes and to bowl is, (2x + 7) dollars
In the second case, he paid $5 to rent a pair of shoes and y dollars an hour to bowl and bowled for 3 hours on Saturday.
Here, the cost to bowl for one hour is y dollars. So, the cost to bowl for 3 hours is (3 × y) = 3y
Now, the total expenditure for shoes and to bowl is, (3y + 5) dollars.
As the total expenditure is the same in these two cases. Therefore, we can conclude,
(2x + 7) = (3y + 5)
Or, 2x - 3y = -2

The profit from the expenditure of x thousand dollars on advertising is given by P(x)=930+15x-4x^2.
Find the marginal profit when the expenditure is x = 7.
The marginal profit is -41 dollars.
In accounting, a profit is an income that is given to the owner throughout a successful market producing process (business).
Profitability, which is the owner's primary interest in the income-formation process of market production, is measured by profit. There are various profit metrics that are frequently used.When one more unit is manufactured and sold, a company or individual will make a profit known as marginal profit. The additional expense or profit made when producing the following unit is referred to as marginal. While marginal cost is the additional expense for producing one extra unit, marginal product is the additional income earned.The advertising is given by P(x) = 930 + 15x -4x².
The marginal profit at x = 7 is given by
P(x) = 930 + 15x -4x²
P'(x) = 15 - 8x
Now at x = 7 the marginal profit is
P'(7) = 15 - ( 8×7 )
or, P'(7) = -41
Hence there will be marginal profit of -41 dollars.

Ms. U.S. Bonds invested a total of $4500, some at 9% per year and the rest at 6% per year. The return for the 9% investment exceeds that from the 6% investment by $180. How much did she Invest at each rate
Using simple interest, the amounts she invested are given as follows:
$3,000 at 9%.$1,500 at 6%.Simple InterestSimple interest is used when there is a single compounding per time period, usually measured in years.
The amount of money after t periods in is modeled by:
A(t) = P(1 + rt)
The interest accrued after t periods is modeled by:
I(t) = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.She had two investments, investing a total of $4500, hence:
[tex]P_1 + P_2 = 4500[/tex]
The return for the 9% investment exceeds that from the 6% investment by $180, hence:
[tex]I_2 = 0.06(4500 - P_1)[/tex][tex]I_1 = 0.09P_1[/tex][tex]I_2 = I_1 - 180[/tex]Then:
[tex]I_2 = 0.06(4500 - P_1)[/tex]
[tex]I_1 - 180 = 0.06(4500 - P_1)[/tex]
[tex]0.09P_1 - 180 = 0.06(4500 - P_1)[/tex]

The required implicit solution to the initial-value problem would be 5x²- y² = 9.5 which is the equation of a hyperbola.
What is the hyperbola?Hyperbola is defined as a conic section, a two-branched open curve, produced by the intersection of a circular cone.
(x-h)²/b² - (y-k)²/a² = 1
We have been given that 5x²- y² = c is a one-parameter family of solutions of the differential equation.
To determine an implicit solution to the initial-value problem ydy/dx = 5x
⇒ y dy/dx = 5x
⇒ y dy = 5x dx
⇒ y²/2 = 5x²/2 + c
If y(3) = −8 which is the means that when substitute x = 3 then y = -8
⇒ (-8)²/2 = 5(3)²/2 + c
⇒ 64/2 = 5(9)/2 + c
⇒ 32 = 22.5 + c
⇒ c = 9.5
Substitute the value of c in the given function 5x²- y² = c
⇒ 5x²- y² = 9.5 which is the equation of a hyperbola.
Therefore, the implicit solution to the initial-value problem would be 5x²- y² = 9.5.

Step-by-step explanation:
You want the piecewise function that describes the relation shown in the graph.
RelationThe relation shown consists of three line segments connecting the points ...
(-6, 5) and (-4, -2)
(-4, -2) and (1, -1)
(1, -1) and (5, 8)
LinesThe equations for the lines between the pairs of points can be written using the slope formula and the point-slope equation of a line.
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
And the point-slope equation of a line is ...
y -y1 = m(x -x1)
If we add y1 to the equation of the line, and substitute the equation for m, we get ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . . a 2-point formula for a line
ApplicationBetween x-values -6 and -4, the equation of the line will use the first pair of points:
y = (-2 -5)/(-4 -(-6))(x -(-6)) +5
y = -7/2(x +6) +5 = -7/2x -16
Between x-values -4 and 1, the equation of the line will use the second pair of points:
y = (-1-(-2))/(1 -(-4))(x -(-4)) +(-2)
y = 1/5(x +4) -2 = 1/5x -6/5
Between x-values 1 and 5, the equation of the line will use the last pair of points:
y = (8 -(-1))/(5 -1)(x -1) +(-1)
y = 9/4(x -1) -1 = 9/4x -13/4
Piecewise functionThe piecewise function uses the equation for the line that is applicable for the appropriate x-values. We have listed those sets of x-values above.
We need to make sure that the function has only one definition for any given value of x. When two segments have a point in common, we need to make sure only one segment includes it.

write a quadratic equation that opens down and has vertex at (2,-8)
The quadratic equation that opens down and has vertex at (2,-8) is y = (-|a|)*(x - 2)² + (-8).
The graph of a quadratic function has the shape of a parabola. Although a parabola's "width" or "steepness" and direction of opening can differ, they all have the same basic "U" shape. If the leading coefficient is larger than zero, the parabola opens upward; if it is less than zero, it opens downward.
The quadratic equation's vertex form is y = a*(x - h)2 + k.
Given that (2,-8) or (h, k) is the vertex point (2,-8)
Since the graph starts out downward, a will have a negative value.
Since |a| is the magnitude of a, the quadratic equation will then be written as y = (-|a|)*(x - 2)2 + (-8).
Consequently, y = (-|a|)*(x - 2)2 + is a quadratic equation that opens downward and has a vertex at (2,-8). (-8).
