The polygons (quadrilaterals) are similar by the congruency of three interior angles and the equal ratios (5 : 4) of  a pair of adjacent sides. The correct option is therefore

B. Yes; PQSN ~ AGKD, scale factor; 5 : 4

Similar polygons are polygons that have the same interior angle, and proportional dimensions.

The specified parameters indicate that we have;

Polygon PQSN and AGKD are quadrilaterals

Length of sides of polygon PQSN

Length of side PQ = 10, QS = 7.5, SN = 15, NP = 15

Length of sides of polygon AGKD

AG = 12, GK = 12, KD = 8, DA = 6

The measure of the angles are;

∠K ≅∠S

∠S ≅ ∠A

∠N = ∠G = 90°

The angle sum property of a quadrilateral indicates that the measure of the fourth angle of both quadrilateral are congruent

The ratio of two adjacent sides of the quadrilaterals are;

7.5/6 and 10/8

7.5/6 = 1.25

10/8 = 1.25

Therefore;

[tex]\dfrac{7.5}{6} =\dfrac{10}{8} =1.25[/tex]

The ratio of two adjacent sides of the quadrilaterals PQSN and AGKD are therefore the same.

The three interior angles of quadrilateral PQSN are congruent to three interior angles of quadrilateral AGKD, and the ratio of two adjacent sides from each quadrilateral are the same, therefore,  quadrilaterals are PQSN is similar to quadrilateral AGKD

Answer:

The transformations applied to the parent function k(x)=x| to obtain f(x)= -1/2|x+3/-1 are reflection in the y-axis, vertical stretching by a factor of 1/2, and a horizontal shift of 3 units to the right.

Step-by-step explanation:

To obtain f(x) from k(x), we first reflect k(x) in the y-axis, which changes the sign of the function and flips it over the x-axis. This gives us -k(x). Next, we vertically stretch the graph of -k(x) by a factor of 1/2. This makes the graph of -k(x) taller and narrower. Finally, we shift the graph of -k(x) 3 units to the right. This moves the entire graph 3 units to the right on the x-axis. The resulting function is f(x)=-1/2|x+3/-1.To understand why these transformations were applied, it's helpful to consider the effect of each transformation on the graph of k(x)=x|. Reflecting in the y-axis flips the graph over the x-axis and changes the sign of the function, so it becomes -k(x). Vertical stretching by a factor of 1/2 makes the graph of -k(x) taller and narrower. Finally, shifting the graph of -k(x) 3 units to the right moves the entire graph 3 units to the right on the x-axis. This results in the graph of f(x)=-1/2|x+3/-1.

Answer:

(Assuming it is k(x) = |x| and f(x) = -1/2|x+3| -1

Scale vertically by a factor of -1/2

Shift left 3

Shift down 1

Step-by-step explanation:

The -1/2 is multiplied by everything, so it scales the graph vertically by -1/2. The -1 is again, everything(as opposed to just modifying the x), so it shifts the graph down by 1.

The + 3 is a little more confusing. Basically, x would have to be x-3(which is shifting the graph left) in order to retain the same x-value(to make the equation true) for the same value. This is the same for y, but we usually isolate y so it doesn't come up as often. If we add 1 to both sides, we get [tex]f(x) + 1= -1/2|x+3|[/tex], and for the same reasoning the graph would shift down 1 even though it is f(x) + 1, because for the same x-value the y-value would need to be 1 less to make the equation to hold true.

We know that there are 850 more red marbles left than blue marbles by solving equations.

The equals sign is used in mathematical equations to indicate that two expressions are equal.

An equation is a claim that demonstrates the equality of two mathematical expressions, according to algebra.

For instance, the word "equal" separates the formulas 3x + 5 and 14, which together form the equation 3x + 5 = 14.

So, a number of red marbles more than blue marbles is:

Mackenzie has 3200 more red than yellow marbles.
y + 3200 = r

Additionally, she has 3840 more blue than yellow marbles.

y + 3840 = b

Assume Mackenzie has one yellow marble, then.

1 + 3200 = 3201 red marbles

1 +3840 = 3841 blue marbles

She will have left over 2351 blue marbles after giving away 1490

3841 - 1490 = 2351

She now has 3201 red marbles and 2351 blue marbles.

r - b =?

3201 - 2351 = 850

Therefore, we know that there are 850 more red marbles left than blue marbles by solving equations.

Miles has to spend $295.3375 on his new computer.

Sales tax is applied to the price after the discount is applied because discounts are typically provided directly by the retailer and lower both the sales price and the money the retailer receives.

So Original price of Computer  is $325.00

Discount with computer is 15% off.

15% of $325 is (325*15)/100 = $48.75.

Price of computer after discount = 325-48.75 =$276.25

Now sales tax will be applied on this price.

7% sales tax = 0.07

amount of sales tax = 276.25*0.07 = 19.3375

If you train 10 distinct models on the same training data, try integrating them into a voting ensemble, which will eventually produce better results.

Voting is an ensemble technique for making predictions by combining the results of various models. The predictive performance of an ensemble is better than that of a single predictive model in a predictive modeling issue. This is accomplished by the model adding bias, which lowers the variance component of the prediction error

calculation

Voting ensembles frequently produce even better results, so try combining them.

The models should differ greatly for it to operate. 95 percent accuracy.

We will therefore get better results if we combine them.

The total volume of all 10 holes and pipes is about 24.135 cubic feet.

Generally, To calculate the volume of the holes, you can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

In this case, the radius of the hole is 0.5 feet (since the hole is 1 foot across and the diameter of the pipe is 3 inches, which is 0.25 feet), and the height is 3 feet. Plugging these values into the formula, we get:

Volume = π * 0.5^2 * 3 = 0.785 * 3 = 2.355 cubic feet

So each hole has a volume of about 2.355 cubic feet. To find the total volume of all 10 holes, you can simply multiply this number by 10:

Total volume = 2.355 * 10 = 23.55 cubic feet

This is the volume of the holes themselves, not including the volume of the pipes. To find the volume of the pipes, you can use the same formula, but with the radius of the pipe (which is 1.5 inches, or 0.125 feet) and the length of the pipe (which is 3 feet).

Volume = π * 0.125^2 * 3 = 0.0195 * 3 = 0.0585 cubic feet

So the volume of one pipe is about 0.0585 cubic feet. To find the total volume of all 10 pipes, you can multiply this number by 10:

Total volume = 0.0585 * 10 = 0.585 cubic feet

23.55 + 0.585 = 24.135 cubic feet.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Equation}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

The given scenario can be modelled as an exponential equation.

Let y be the area the fire covers (in meters squared).

Let x by the time (in hours).

If the fire currently covers an area of 32 m² then the initial value, a, is 32.

If the area covered by the fire increases by 17% each hour, then the growth factor, b, is 1.17 (since an increase of 17% is 117% of the previous amount).

Therefore:

Substitute the values of a and b into the exponential formula:

[tex]y=32(1.17)^x[/tex]

To find the area that the first covers in 20 hours' time, simply substitute x=20 into the equation:

[tex]\implies y=32(1.17)^{20}[/tex]

[tex]\implies y=32(23.1055991...)[/tex]

[tex]\implies y=739.37917...[/tex]

Therefore, the area the fire will cover in 20 hours' time is 739 m²  (nearest 1 m²).
