The graph of [tex]y = \sqrt{-2x[/tex] relates to its parent function as a result of (d) horizontal compression by a factor of 2, and a reflection across the y-axis

A function transformation involves changing the form or equation of a function to another through reflection, dilation, translation or rotation

The parent function is given as:

[tex]y = \sqrt x[/tex]

Compress the function horizontally by a factor of 2, using the following rule

[tex](x,y) \to (2x,y)[/tex]

So, we have:

[tex]y = \sqrt {2x[/tex]

Next, reflect the function over the y-axis, using the following rule

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex]y = \sqrt {-2x[/tex]

Hence, the function transformation is (d)

Answer: Option c. $ 611.20 will be correct.

Explanation:

Since, the total amount of finance charge is [tex]A=P\frac{r(1+r)^n}{(1+r)^n-1}[/tex]

Where P is the principle, r is the rate, n is the times of compound interest (monthly or quarterly etc.) .

Here P=$4250 r=13.25%, and n=24.

So according to the formula So, the finance charge= [tex]4250\frac{13.25(1+13.25)^{24}}{(1+13.25)^{24}-1}[/tex] =  $ 611.20

The total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months is c) $611.20.

To calculate the total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months, we can use the following formula:

Total finance charge = Principal * (1 + Monthly interest rate)^Number of months - Principal

Where:

Principal is the amount of the loan ($4,250)

Monthly interest rate is the annual interest rate divided by 12 (13.25% / 12 = 1.1042%)

Number of months is the term of the loan in months (24)

Total finance charge = 4250 * (1 + 0.011042)^24 - 4250

Total finance charge = 611.20

Therefore, the answer is c. $611.20.

Note that this formula is for calculating the total finance charge over the entire term of the loan. If you want to calculate the monthly finance charge, you can simply divide the total finance charge by the number of months in the loan term. For example, the monthly finance charge for this loan would be $611.20 / 24 = $25.47.

1/4 and 33/16 are the last ones

and for the multiple choice answer which is last is A

Step-by-step explanation:

To solve the quadratic equation 2x^2 + x - 4 = 0, we can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a). Substituting the given values into the formula, we find two solutions: x = (-1 ± √33) / 4.

To solve the equation 2x2 + x - 4 = 0, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax2 + bx + c = 0, the solutions for x can be found using the formula:

x = (-b ± √(b2 - 4ac)) / (2a)

For our equation, a = 2, b = 1, and c = -4. Substituting these values into the formula, we have:

x = (-1 ± √(1 - 4(2)(-4))) / (2(2))

Simplifying further, we get two solutions: x = (-1 ± √33) / 4.

Answer:

[tex]\bigg(\displaystyle\frac{f}{g}\bigg)(5) = 270[/tex]

Step-by-step explanation:

We are given the following information in the question:

[tex]f(x) = 7 +4x\\\\g(x) = \displaystyle\frac{1}{2x}[/tex]

We have to find the values of [tex]\displaystyle\frac{f}{g}(x)[/tex]

[tex]\bigg(\displaystyle\frac{f}{g}\bigg)(x) = \frac{f(x)}{g(x)} = \frac{7 + 4x}{\frac{1}{2x}} = 2x(7+4x)[/tex]

Putting x = 5, we have:

[tex]\bigg(\displaystyle\frac{f}{g}\bigg)(x) = 2x(7+4x)\\\\\bigg(\displaystyle\frac{f}{g}\bigg)(5) = 2(5)(7+20)=270[/tex]

270 is the required value of [tex]\bigg(\displaystyle\frac{f}{g}\bigg)(5)[/tex].

The sum of the geometric series with a1 = 7, r = 2, and n = 14 is -327661.

The question is asking for the sum of a geometric series. In mathematics, the sum (S) of a geometric series is determined using the formula S = a1 * (1 - r^n) / (1 - r), where a1 is the first term, r is the common ratio, and n is the number of terms.

In the provided geometric series, a1 = 7, r = 2, and n = 14. Substituting these values into the formula gives us S = 7 * (1 - 2^14) / (1 - 2). After performing the calculations, the sum of the geometric series is -327661.

The sum of the first 14 terms of the geometric series with the first term (a1) = 7, common ratio (r) = 2, is 114,691.

Given the first term of the geometric series (a1) = 7, the common ratio (r) = 2, and the number of terms (n) = 14, we would like to find the sum of this series.  Using the formula for the sum of a geometric series, S = a1 * (1 - r^n) / (1 - r), substituting the given values, we get:

S = 7 * (1 - 2^14) / (1 - 2)

This simplifies to S = 7 * ( -16383) / -1, which results in S = 114,691. So, the sum of the first 14 terms of this geometric series is 114,691.

Step-by-step explanation:

The triangle ABC is not a right angle triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

The measure of side AB = 8 inches

The measure of side BC = 12 inches

The measure of side AC = 16 inches

Now , For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Substituting the values in the equation , we get

AC² = AB² + BC²

16² = 8² + 12²

256 ≠ 64 + 144

256 ≠ 208

Therefore , it does not satisfy Pythagoras relation

Hence , the triangle is not a right angle triangle
