The polynomial function is the product of two different linear factors, (x-2) and (x+3)^2, which means that we have two different roots, x=2 and x=-3
What are the roots the given polynomial function have?A polynomial function is a function that can be written as constants and n is the degree of the polynomial. The polynomial function y = (x − 2)(x + 3)² is a quadratic function because it has an [tex]x^{2}[/tex] term.
The roots of a polynomial function are the values of x that make the function equal to zero. In other words, they are the solutions to the equation y = 0.
The polynomial function y = (x − 2)(x + 3)² can be factored as (x-2)(x+3)(x+3), which means that we have three different linear factors, (x-2), (x+3), and (x+3) . Each linear factor corresponds to one root of the polynomial.
So the polynomial function y = (x − 2)(x + 3)² has 2 distinct roots. The correct answer is C.
Alternatively, we can also see that the polynomial function is the product of two different linear factors, (x-2) and [tex](x+3)^{2}[/tex], which means that we have two different roots, x=2 and x=-3.

Square 1 ABDC square 2 FGEH. AD= 18 DC=12 FE= 15 how do I find the square factor?
Using the similarity rectangle theorem, the value of FG is approx 23.
We determine the value of FG using the using the similar rectangle theorem.
Two rectangles must have proportional sides in order for them to be identical (form equal ratios). The two shorter sides should be proportionately equal to the two longer sides.
The rectangle ABCD and FGEH are both have same shape.
As we know that the rectangle same two sides equal. So
FG/EF = AD/DC
FG/15 = 18/12
Multiply by 15 on both side, we get
FG = 18/12 * 15
FG = 3/2 * 15
FG = 22.5

Relative frequency distributions are generally more useful than frequency distributions when?
Relative frequency distributions are generally more useful than frequency distributions when comparing data sets of the same size.
The frequency (or absolute frequency) of an event in statistics is the number of times the event occurred in an experiment or research. Histograms are frequently used to graphically show these frequencies.
The absolute frequency of an occurrence normalized by the total number of events is referred to as its relative frequency (or empirical probability). A frequency distribution can be created by plotting the values of all events.
A histogram is a graphical representation of tabulated frequencies that is displayed as consecutive rectangles erected at discrete intervals (bins) with an area equal to the frequency of the observations in the interval.
The frequency density of the interval, i.e. the frequency divided by the width of the interval, is also equal to the height of a rectangle.

what is the measure of the acute angle formed by the hands of a clock at $4:20$ a.m.? express your answer as number of degrees.
The acute angle formed by the hands of a clock at 4:20a.m is 10°.
For the minute hand, we can compute that, for its every move, it covers 6 degrees. And for the hour hand, each move covers 30 degrees.
A clock is a circle, and a circle always contains 360 degrees. Since there are 60 minutes on a clock, each minute mark is 6 degrees.
The angle between the hour's hand and the minute hand when the clock shows 4:20 pm can be calculated by using the formula:
Angle=|11/2 M-30H|
where M= minute H= hour's
Here M=20 H=4
Therefore we get the angle |11/2(20)- 30*4|=|110-120|=|-10°|=10°
Hence, 10° is the correct answer.

What is the probability that Andre, Olivia, and Zach all win gift cards that are at least $25?
The probability that Andre, Olivia, and Zach all win gift cards that are at least $25 is 0.
Since the value of the gift cards is determined by chance, it is impossible to calculate the probability of this exact outcome. Instead, we can calculate the probability of any one person winning a gift card that is at least $25, which is 0.5.
The probability of them all winning would be the product of the individual probabilities, which is 0.5 x 0.5 x 0.5 = 0.125. However, since this is impossible, the probability of this exact outcome is 0.

The speed of light is 3 x 10 8squared m/s. if its frequency is 4.11 x 10 4squared Hz, what is its wavelengeth
Taking into account the definition of wavelength, frecuency and propagation speed, the wavelength of a wave with a frequency of 4.11×10⁴ Hz is 7299.27 m.
WavelengthWavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).
FrequencyFrequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).
Propagation speedThe propagation speed is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.
The propagation speed relate the wavelength (λ) and the frequency (f) using the following equation:
v = f×λ
Wavelengeth in this caseIn this case, you know:
v= 3×10⁸ m/s
f= 4.11×10⁴ Hz
λ= ?
Replacing:

They are called this way because of their use in singular value decomposition. Say A=UΣVH , then the columns of U are the left-singular vectors and the columns of V are right-singular vectors.
We know that the non-zero eigenvalues of AAH and AHA are the same, they are the squares of the singular values of A . A singular of value of A is a value σ such that Av=σu AHu=σv where u is a left-singular vector and vs a right-singular vector.

What is algebraic expression?Algebraic expressions serve as the mathematical statement when operations such as addition, subtraction, multiplication, division, etc. are performed on variables and constants. Let's imagine that while playing with matchsticks, James and Natalie came up with the idea to arrange the sticks into patterns that represented numbers.
James drew a four in the air with four matchsticks. Natalie was able to make a pattern with two 4s by putting three more matchsticks on the board. They realised they could proceed to add three matchsticks each round until they had a total of four. This led them to the conclusion that, in general, 4+ 3(n-1) sticks are needed to make a pattern with n numbers of 4s. This sentence makes reference to the algebraic expression 4+ 3(n-1).
The total no. of tables are 32
Let x be the no. of Small tables = 2x
And y be the no. of Large tables = 4y
Total no. of tables = 12
2x + 4y = 32
And
x + y = 12
x = 12 - y
Putting the value of x in first equation
2(12 - y) + 4y = 32
24 - 2y + 4y = 32
4y - 2y = 32 - 24
2y = 8
y = 4
