The dimensions of the photograph are found as 13 in and 6 in.

Let length = x.

So, width = x - 7

Area = length x width

A = x (x -7)

and A = 78 inches squared.

Thus,

78 = x (x -7)

On solving.

x² - 7x - 78 = 0

Find the factors of the quadratic equation,

x² - 7x - 78 = 0

(x - 13)(x + 6) = 0

Thus,

x = 13 and x = -6 but (x > 0)

Thus, when x = 13 in,

Width = x + 7

Width = 13 - 7

Width = 6 in

Thus, the dimensions of the photograph are found as 13 in and 6 in.

Answer:

2) m∡1 = 100°

3) m∡2 = 40°

4) TD

5) m∡1 = 67°

Step-by-step explanation:

The amplitude of the wave is 2 m.

The wavenumber of the wave is 4 \(m^-^1\).

The angular frequency of the wave is 2 \(s^-^1\).

The period of the wave can be calculated using the formula T = 2π/ω, where T is the period and ω is the angular frequency. In this case, T = 2π/2 = π s.

The wavelength of the wave can be determined using the formula λ = 2π/k, where λ is the wavelength and k is the wavenumber. In this case, λ = 2π/4 = π/2 m.

The speed of the wave can be calculated using the formula v = λ/T, where v is the speed, λ is the wavelength, and T is the period. In this case, v = (π/2)/(π) = 1/2 m/s.

The direction in which the wave moves can be determined by examining the coefficient of the x-term in the equation. In this case, the coefficient is positive (+4), indicating that the wave moves in the positive x-direction.

The phase constant is determined by the argument of the sine function in the equation. In this case, the phase constant is 3π.

To find the displacement at x = 0.5 m and t = 0.5 s, we substitute these values into the equation. y(0.5, 0.5) = 2sin(4(0.5)+2(0.5)+3π) = 2sin(2+1+3π) = 2sin(3+3π) = 2sin(3π) = 0. The displacement at x = 0.5 m and t = 0.5 s is 0.

The given equation provides information about the properties of the wave. The amplitude (2 m) represents the maximum displacement of the wave from its equilibrium position. The wavenumber (4 m^(-1)) indicates the number of wavelengths per unit distance. The angular frequency (2 s^(-1)) represents the rate at which the wave oscillates in radians per second. The period (π s) is the time it takes for one complete cycle of the wave. The wavelength (π/2 m) is the distance between two consecutive points in the wave that are in phase. The speed of the wave (1/2 m/s) is the rate at which the wave propagates through space. The positive coefficient of the x-term indicates that the wave moves in the positive x-direction. The phase constant (3π) represents the initial phase of the wave. Finally, substituting x = 0.5 m and t = 0.5 s into the equation gives a displacement of 0 at that point in space and time.

Therefore, the numerator of the given equation comes out to be 4x+6

A fraction denotes a component of a whole or, more generally, any number of equal parts. In conversational English, a fraction, such as one-half, eight-fifths, or three-quarters, denotes the quantity of a specific size of portions.

Given

\(\frac{x}{x^{2} +3x+2} + \frac{3}{x+1}\)

A common denominator must exist for the fractions before we can add them.

Factor the denominator of the first fraction

\(\frac{x}{(x+1) (x+2)} + \frac{3}{x+1}\)

Subtract (x + 2) from the second fraction's numerator and denominator.

\(\frac{x}{(x+1) (x+2)} + \frac{3(x+2)}{(x+2)(x+1)}\)  ← Currently, fractions share a common denominator.

Add the numerators leaving the denominators

= \(\frac{(x+2)(x+3)}{(x+2)(x+1)}\)  

= \(\frac{x^{2} +3x+6}{(x+2)(x+1)}\)

=  \(\frac{4x+6}{(x+2)(x+1)}\)

simplified sum with numerator 4x + 6

Therefore the numerator of the given equation comes out to be 4x+6.

Answer:

Slope-intercept

y = 3/4(x) - 7

Point slope

y -5= 3/4(x - 16)

Step-by-step explanation:

In slope-intercept

We have the general slope intercept as;

y = mx + b

where m is the slope and b is the y-intercept

in this case, m = 3/4 and b = -7

So we have;

y = 3/4(x) - 7

In point-slope

we have the general form as;

y-y1 = m(x-x1)

So what we have is as follows;

y -5= 3/4(x - 16)

Where we have (x1,y1) = (16,5)

The condition that p(x)/q(x) is an integer for any number of inputs of integers x is satisfied by the integer polynomials p and q. It's not necessary for q(x) to split p(x).

In mathematics, a polynomial with integer values (also called a numerical polynomial) has an integer value for each integer n.

Contrary to popular belief, every polynomial with integer coefficients has integer values.

For instance, when t is an integer, the polynomial takes on integer values.

So, polynomials are the sums of terms of the form kˣⁿ, where k is any number and n is a positive integer.

A description of polynomials, such as the polynomial 3x+2x-5.

The concepts of degree, standard form, monomial, binomial, and trinomial are all covered in this section.

A. In a randomized block design, each block is a group of experimental units that are similar with respect to some known characteristic. Each block is randomly assigned to one treatment to reduce variability within blocks.

B. In a completely randomized experimental design ANOVA procedure, the MSE (mean square error) represents the within-treatment estimate of population variance. The MSE is a measure of the variability of the data within each treatment group.

C. For full factorial experimental design ANOVA procedure, the f-statistic can be calculated by taking the mean square due to treatments divided by the mean square due to error. The f-statistic is used to test whether the treatments have a significant effect on the response variable.

D. Randomization is the process of assigning the treatments to the experimental units in a random and unbiased manner to minimize the effect of extraneous variables. The goal of randomization is to ensure that the differences between the treatment groups are due to the treatments themselves and not to any systematic differences between the groups. Therefore, the statement that randomization is the process of assigning the treatments to the experimental units in a systematic or subjective basis is false.

Aryabhata, also called Aryabhata I or Aryabhata the Elder, (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

Aryabhatasiddhanta circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).

The 6th shape in this pattern is an octagon, which has 8 sides. This pattern follows a sequence of shapes, beginning with a triangle which has 3 sides, followed by a square which has 4 sides, then a pentagon which has 5 sides, and so on.

The conclusion that is correct in a two-tailed test at α = .05 is There appears to be no difference in the mean occupancy rates.

From the given values:

Thus, the P-value = 0.1791

Interpret results. Since the P-value (0.1791) is greater than the significance level (0.05), we failed to reject the null hypothesis.

From the above test, we do not have sufficient evidence in favor of the claim that there is a difference in the mean occupancy rates.
