Eli and his children went into a movie theater and will buy candies and pretzels. Each candy costs $3.50 and each pretzel costs $3.25. Eli has a total of $30 to spend on candies and pretzels. Write an inequality that would represent the possible values for the number of candies purchased, cc, and the number of pretzels purchased, p.p.

62 points, he would need to improve his credit score in order to take a mortgage for $150,000.

What is a mortgage?

It is an agreement between you and a lender that allows you to borrow money to purchase or refinance a home and gives the lender the right to take your property if you fail to repay the money you've borrowed. A mortgage is a type of loan that's used to finance the property. A mortgage is a type of loan, but not all loans are mortgages. Mortgages are “secured” loans.

To calculate the monthly payment, we can use the formula:

M = P [i(1 + i)^n] / [(1 + i)^n – 1]

Where M is the monthly payment, P is the loan amount, i is the interest rate, and n is the number of payments (in this case, the number of months in 30 years)

Plugging in the values,

M = 150000 * (0.0929 / 12) / [ (1 + (0.0929 / 12))^(12 * 30) - 1]

This gives a monthly payment of $1238.

To find out how many points he needs to improve his credit score, we can compare this monthly payment to the maximum monthly payment he can afford, which is $14,000.

If $1238 is more than $14,000, he would need to improve his credit score to a point where the monthly payment would be less than $14,000. By looking at the table, we can see that the interest rate for credit score of 620-674 is 7.40%.

Hence, (D) option is the correct answer.

It is true that the indexed variables (members) of an array must be integers.

The indexed variables or members of an array must be integers. This is because arrays are data structures that store elements in a contiguous block of memory, and each element is accessed using an index. Indexing allows us to uniquely identify and retrieve specific elements within the array. In most programming languages, including C, C++, Java, and Python, array indices are integers and must be whole numbers (positive or negative) without any fractions or decimals. Attempting to use non-integer values as indices would result in a compilation error or unexpected behavior.

Step-by-step explanation:

The root of the equation sinx = 2x-3 is 0.8401 (approx).

Given equation is sinx = 2x-3

We need to solve this equation using false position method.

False position method is also known as the regula falsi method.

It is an iterative method used to solve nonlinear equations.

The method is based on the intermediate value theorem.

False position method is a modified version of the bisection method.

The following steps are followed to solve the given equation using the false position method:

1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.

Here, f(x) = sinx - 2x + 3.

2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))

3. Evaluate the function at point c and find the sign of f(c).

4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.

5. Repeat the steps 2 to 4 until we obtain the required accuracy.

Let's solve the given equation using the false position method.

We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.

So, the root lies between 0 and 1.

The calculation is shown in the attached image below.

Therefore, the root of the equation sinx = 2x-3 is 0.8401 (approx).

Answer:

21 is the correct answer

Step-by-step explanation:

Consider that we need to find \((a+b)(x), (a-b)(x), (ab)(x),\left(\dfrac{a}{b}\right)(x)\).

Given:

The functions are:

\(a(x)=4x+9\)

\(b(x)=3x-5\)

To find:

The function operations \((a+b)(x), (a-b)(x), (ab)(x),\left(\dfrac{a}{b}\right)(x)\).

Solution:

We have,

\(a(x)=4x+9\)

\(b(x)=3x-5\)

Now,

\((a+b)(x)=a(x)+b(x)\)

\((a+b)(x)=4x+9+3x-5\)

\((a+b)(x)=7x+4\)

Similarly,

\((a-b)(x)=a(x)-b(x)\)

\((a-b)(x)=4x+9-(3x-5)\)

\((a-b)(x)=4x+9-3x+5\)

\((a-b)(x)=x+14\)

And,

\((ab)(x)=a(x)b(x)\)

\((ab)(x)=(4x+9)(3x-5)\)

\((ab)(x)=12x^2-20x+27x-45\)

\((ab)(x)=12x^2+7x-45\)

And,

\(\left(\dfrac{a}{b}\right)(x)=\dfrac{a(x)}{b(x)}\)

\(\left(\dfrac{a}{b}\right)(x)=\dfrac{4x+9}{3x-5}\)

Therefore, the required functions are \((a+b)(x)=7x+4\), \((a-b)(x)=x+14\), \((ab)(x)=12x^2+7x-45\) and \(\left(\dfrac{a}{b}\right)(x)=\dfrac{4x+9}{3x-5}\).

Remember that the sum of the interior angles of any triangle must be equal to 180°.

Now, looking at the triangle in the left, we can see that the top angle is equal to:

180 - 2α

The right angle is equal to:

180 - 2β

And the left angle is α

Then we can write:

α + (180 - 2α) + (180 - 2β) = 180

-α - 2β = -180

α = 180 - 2β

Now we can go to the other triangle, where theta is, and write:

Tri-County will have to charge approximately $83.1 per MWh to break even.

To calculate the break-even price that Tri-County will have to charge to cover its costs, we need to consider both the fixed costs and the variable costs. The fixed costs are given as $80.1 million per year.

The variable costs are calculated by multiplying the quantity of electrical power sold (150,000 MWh per year to Boulder) by the variable cost per MWh ($20). Therefore, the variable costs amount to 150,000 MWh/year * $20/MWh = $3 million per year.

To cover both fixed and variable costs, Tri-County needs to charge a total amount that equals the sum of these costs. The total cost is $80.1 million + $3 million = $83.1 million per year.

Now, let's calculate the break-even price per MWh. Since Tri-County has a demand of 1,000,000 MWh from its customers (other than Boulder), we can divide the total cost by this quantity to find the break-even price.

Break-even price = Total cost / Quantity of electrical power demanded
Break-even price = $83.1 million / 1,000,000 MWh = $83.1/MWh

Therefore, Tri-County will have to charge approximately $83.1 per MWh to break even.

The maximum value of f(x,y) on the disk D is attained on the boundary of the disk, where x^2 + y^2 = 1. Since f(x,y) = 18x^2 + 19y^2 is increasing in both x and y, the maximum value is attained at one of the points (±1,0) or (0,±1), where f(x,y) = 18. The minimum value of f(x,y) on the disk D is attained at the point (√(19/36), √(18/38)), where f(x,y) = 18/36

To find the maximum and minimum values of the function \(f(x,y) = 18x^2 + 19y^2\) on the disk \(D: x^2 + y^2 \leq 1\), we can use the method of Lagrange multipliers.

Let \(g(x,y) = x^2 + y^2 - 1\)be the constraint equation for the disk D. Then, the Lagrangian function is given by:

L(x,y, λ) = f(x,y) - λg(x,y) \(= 18x^2 + 19y^2 -\)λ\((x^2 + y^2 - 1)\)

Taking partial derivatives with respect to x, y, and λ, we get:

∂L/∂x = 36x - 2λx = 0

∂L/∂y = 38y - 2λy = 0

∂L/∂λ = \(x^2 + y^2 - 1 = 0\)

Solving these equations simultaneously, we get two critical points:

(±√(19/36), ±√(18/38))

To determine whether these points correspond to maximum, minimum or saddle points, we need to use the second derivative test. Evaluating the Hessian matrix of second partial derivatives at these points, we get:

H = [ 36λ 0 2x ]

[ 0 38λ 2y ]

[ 2x 2y 0 ]

At the point (√(19/36), √(18/38)), we have λ = 36/(2*36) = 1/2, x = √(19/36), and y = √(18/38). The Hessian matrix at this point is:

H = [ 18 0 √(19/18) ]

[ 0 19 √(18/19) ]

[ √(19/18) √(18/19) 0 ]

The determinant of the Hessian matrix is positive and the leading principal minors are positive, so this point corresponds to a local minimum of f(x,y) on the disk D.

Similarly, at the point (-√(19/36), -√(18/38)), we have λ = 36/(2*36) = 1/2, x = -√(19/36), and y = -√(18/38). The Hessian matrix at this point is:

H = [ -18 0 -√(19/18) ]

[ 0 -19 -√(18/19) ]

[ -√(19/18) -√(18/19) 0 ]

The determinant of the Hessian matrix is negative and the leading principal minors alternate in sign, so this point corresponds to a saddle point of f(x,y) on the disk D.

Therefore, the maximum value of f(x,y) on the disk D is attained on the boundary of the disk, where \(x^2 + y^2 = 1\). Since f(x,y) = \(18x^2 + 19y^2\) is increasing in both x and y, the maximum value is attained at one of the points (±1,0) or (0,±1), where f(x,y) = 18. The minimum value of f(x,y) on the disk D is attained at the point (√(19/36), √(18/38)), where f(x,y) = 18/36.
