What is equivalent to 9(w+8)

Answer:

400

The ladder is the hypotenuse of a right triangle. The 2 feet from the wall on the ground is one side, the distance up the wall is another side.

In a right triangle, the square of the hypotenuse is the sum of the squares of the other two sides. This is called the Pythagorean Theorem. In equation form:

c^2 = a^2 + b^2

Substitute the known values:

20^2 = 2^2 + b^2

Square the numbers:

400 = 4 + b^2

Subtract 4 from both sides:

b^2 = 400 - 4 = 396

Take the square root:

b = sqrt(396) = 19.9 (rounded) feet

Check:

20^2 ?= 2^2 + 19.9^2

400 ?= 4 + 396.01

400 ?= 400.01 (off just a bit due to rounding)

Answer: The usual number of yellow eggs in the selected sample is 26.

Step-by-step explanation:

It is given that there are 2 types of dragon eggs: Yellow and green

Observation says that 39% of the eggs are yellow.

When selected at random for incubation:

Number of eggs selected are = 66

To evaluate the number of yellow eggs, we must calculate 39% of 66 eggs

\(\Rightarrow \frac{39}{100}\times 66\\\\\Rightarrow 25.74\approx 26\)

Hence, the usual number of yellow eggs in the selected sample is 26.

The slope is 4.5

Step-by-step explanation:

Here, we want to find the slope of the line that passes through the given points

Mathematically, we use the slope formula here

Using the slope formula m, we have the equation as follows;

m = (y2-y1)/(x1-x1)

m = (63-18)/(14-4) = 45/10 = 4.5

It is sampled at a rate 25% higher than the Nyquist rate and quantized into L levels. The maximum acceptable error in sample amplitudes is limited to 0.1% of the peak signal amplitude.

To sketch the amplitude spectrum of g(t), we observe that sinc functions centered at 16 kHz and 10 kHz contribute amplitudes of 16x10³ and 10x10³, respectively, while the cosine component centered at 30 kHz has an amplitude of 20x10³. The horizontal axis represents the frequency (f).

The amplitude spectrum of the sampled signal, within the range -50 kHz to 30 kHz, will exhibit replicas of the original spectrum centered at multiples of the sampling frequency. The amplitudes and frequencies should be labeled according to the replicated components.

The minimum required bandwidth for binary transmission can be determined by considering the highest frequency component in g(t), which is 30 kHz. Therefore, the minimum required bandwidth will be 30 kHz.

For M-ary multi-amplitude signaling within a channel bandwidth of 50 kHz, we need to find the minimum value of M. It can be determined by comparing the available bandwidth with the required bandwidth for each amplitude component of g(t). The minimum M will be the smallest number of levels needed to represent all the significant amplitude components without violating the bandwidth constraint.

To minimize M, we need to select a pulse shape that achieves the narrowest bandwidth while maintaining an acceptable level of distortion. Different pulse shapes can be considered, such as rectangular, triangular, or raised cosine pulses.    

If a raised cosine pulse is used, the roll-off factor determines the pulse shape's bandwidth efficiency. The roll-off factor is defined as the excess bandwidth beyond the Nyquist bandwidth. The required M can be calculated based on the available channel bandwidth, the roll-off factor, and the distortion tolerance.

When using delta modulation with a sampling rate of five times the Nyquist rate, the number of levels (L) and corresponding bit rate can be determined by considering the quantization error and the maximum acceptable error in sample amplitudes. The bit rate will be determined based on the number of bits required to represent each level and the sampling rate.

To identify the vertical asymptotes, we have to factor the denominator. For horizontal asymptotes, we compare the degrees of the numerator and denominator.

For rational functions, there are vertical and horizontal asymptotes. To identify the vertical asymptotes, we first have to factor the denominator. After that, we should look for values that make the denominator zero. These values can be found by setting the denominator equal to zero and solving for x. The resulting x values would be the vertical asymptotes of the function.

The horizontal asymptote is the line that the function approaches as x goes towards infinity or negative infinity. For rational functions, the horizontal asymptote is found by comparing the degrees of the numerator and the denominator.

If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is y = the ratio of the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

Step-by-step explanation:

y = f(x) + C C > 0 moves it up

f(x) = f(x) + 6 moves it up 6 units

Answer:

Vertical shift, 6 up.

Step-by-step explanation:

The entire function f(x) has a value of six added to it. That means that regardless of where f(x) was plotted on the coordinate plane, after the translation f(x) + 6, every single point would increase its value by six. Since all points would increase their values by six, the entire function would shift 6 up.

The rate of simple interest is 0.05, which is equivalent to 5% when expressed as a percentage.

Answer:

The Diagonal is 4√5

The arc AB in degrees is equal to \((2π*11.5)/360,\) which is equal to 1.04 radians. In degrees, this is equal to 59.7 degrees, which can be rounded to 59.8 degrees.

The length of the arc in degrees can be calculated by taking the ratio of the circumference of the circle to the total circumference of the circle. The circumference of the circle is equal to 2π times the radius, and the total circumference of the circle is equal to 360 degrees. Therefore, the ratio of the arc AB to the circumference of the circle is equal to the arc AB in degrees divided by 360. The radius of the circle is equal to half the diameter, so the radius of the circle is equal to 11.5 meters. Therefore, the arc AB in degrees is equal to (2π*11.5)/360, which is equal to 1.04 radians. In degrees, this is equal to 59.7 degrees, which can be rounded to 59.8 degrees.

The standard deviation of the sample mean would equal $4,812.71.

We would explain how standard error is used to estimate the standard deviation of the sample mean, which helps to determine the precision of our estimate of the population mean. We would also provide additional context and examples to help the reader understand the importance of standard error in statistical analysis.

The standard error is the standard deviation of the sampling distribution of the mean. In simpler terms, it measures how much the sample means vary from the population mean. The formula for standard error is:
SE = σ / sqrt(n)
where SE is the standard error, σ is the population standard deviation, and n is the sample size.
In this case, we are given that the population standard deviation is $18,000 and the sample size is 14. Plugging these values into the formula, we get:
SE = 18,000 / sqrt(14)
SE = 4,812.71

Answer: D

Step-by-step explanation: y=mx+b

b is -2 because when x is 0, y is -2.

"Rise-over-run" is really helpful in this problem, because with every +1 y value, the x value is increased by two, making the slope 1/2.

Therefore making the equation y=1/2x -2

Answer:

Use the slope equation to solve: \((Y_{2} - Y_{1} ) / (X_{2} - X_{1})\)

Pick any two points: (2, -1), (0, -2)

(-2 - -1) / (0 -2)

(-2+1) / (-2) = 0.5

The slope, m, is 0.5

The y-intercept is when x=0, so it is -2

y-intercept = b

The equation is y=mx+b

y=0.5x - 2

y= 1/2x - 2

The answer is D.) y= 1/2x - 2
