Answer: They both intersect once.

Step-by-step explanation: Solving for x, we get:

3x = 0

x = 0

Now we can substitute x = 0 into either equation to find the y-coordinate:

y = 2(0) + 4 = 4

So the two lines intersect at the point (0,4).

Therefore, the graphs of the equations y = 2x + 4 and y = −x + 4 intersect once.

Answer:

It intersects once.

Step-by-step explanation:

To plot y = 2x + 4, you start at the y-intercept which is 4. Then you go up 2 times, and to the right once.

To plot y = -x + 4, you start at the y-intercept which is also at 4. Then you go down once and to the right one time.

The graph will intersect at (0, 4).

Answer: Therefore, the height of the light pole is 50 feet.

Step-by-step explanation:

We can use proportions to solve the problem.

Let h be the height of the light pole.

Then, we have:

h / 75 = 8 / 12

To solve for h, we can cross-multiply:

12h = 75 * 8

h = (75 * 8) / 12

h = 50

Step-by-step explanation:

The given statement "Measuring the entire population is usually preferred over measuring a sample from the population" is False because measuring the entire population is often impractical or impossible.

When dealing with large populations, it is typically more feasible to gather data from a representative sample rather than measuring the entire population. This approach saves time, resources, and effort. Sampling allows statisticians to make reliable inferences about the population based on the characteristics observed in the sample.

Carefully chosen samples can accurately reflect the population's attributes and provide valuable insights.

However, it is crucial to ensure that the sample is representative and unbiased to avoid potential sampling errors and ensure the validity of the conclusions drawn from the data.

The value Newton's interpolating polynomial P 2(x) of f(x) of f[x0, x1] is -4.

In Newton's interpolating polynomial, the coefficients of the linear terms (x) correspond to divided differences. The divided difference f[x0, x1] represents the difference between the function values f(x0) and f(x1) divided by the difference between x0 and x1.

Since we are given P2(x) = \(x^2 + x + 2\), we can substitute the given x-values into P2(x) to find the corresponding function values.

For x0 = -3, substituting into P2(x) gives f(-3) = \((-3)^2 + (-3) + 2 = 12\).

For x1 = 1, substituting into P2(x) gives f(1) = \((1)^2 + (1) + 2 = 4\).

To calculate f[x0, x1], we need to find the divided difference between these two function values: f[x0, x1] = (f(x1) - f(x0)) / (x1 - x0) = (4 - 12) / (1 - (-3)) = -8 / 4 = -2.

Therefore, f[x0, x1] = -2, and the correct answer choice is b. -4.

Answer:

The rational function is \(f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}\)

The horizontal asymptote occur at y = 1

Step-by-step explanation:

Given that the function has an x-intercept at (-9, 0), we have;

(x + 9) is a factor of the function

Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)

With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5

The general form of the function can be presented as follows;

f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)

Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1

The horizontal asymptote occur at y = 1

Step-by-step explanation:

If Kristens dog weighs 2.5 pounds less, then you just have to subrtact 2.5 from 18.25

The answer is B. 15.75 pounds. Kristen's dog weighs 2.5 pounds less than Milo's dog which is 18.25. So, all you have to do is subtract 2.5 from 18.25. 18.25 - 2.5 = 15.75.

A car is traveling at the speed of 35 miles per hour, and its speed in feet per second will be equal to 51.33 feet per second.

The amount of the shift in approach per time unit or the size of the shift to the right over time for just an object can be used to describe speed, which in everyday language and kinematics is a scalar quantity.

As a time interval's duration goes closer to zero, the beginning speed serves as that of the maximum permitted speed.

The speed of the car in miles per hour = 35 miles/hour

Multiply it by 1.46 to convert the speed to feet/second.

35 × 1.46 = 51.33 feet/second.

If the omnibus null hypothesis is rejected in a one-factor ANOVA, then, we can conclude that at least one of the population means is different from at least one other population mean.

ANOVA table gives us the total sum of squares ( TSS ), the residual sum of squares ( RSS ) and the estimated sum of squares ( ESS ).

It establishes the relation that:

ESS + RSS = TSS.

If we reject the omnibus null hypothesis, then it means that:

at least one of the population means is different from at least one other population mean.

Therefore, we get that, if the omnibus null hypothesis is rejected in a one-factor ANOVA, then, we can conclude that at least one of the population means is different from at least one other population mean.

Therefore, value of r(x) as x approaches Infinity : zero

\(\bold{\lim_{x \to \infty} r(x)=0}\)

"A function is a special relationship where for each input and their is single outputs."

"Limit is defined as the value that a function approaches for the given input value."

For given situation,

We have been given a function,

r (x) = Start Fraction a x Superscript b Baseline + 8 Over c x Superscript d Baseline End Fraction

We can rewrite it as,

\(r(x)= \frac{ax^b+8}{cx^d}\) , where a, b, c, and d are positive integers and b < d.

We need to find the value of r(x) approach as x approaches Infinity.

This means, we need to find the value of the limit \(\lim_{x \to \infty} r(x)\)

Now, we find the value of limit for given function.

\(\lim_{x \to \infty} r(x)\)

=  \(\lim_{x \to \infty} \frac{ax^b+8}{cx^d}\)

= \(\lim_{x \to \infty} (\frac{ax^b}{cx^d} + \frac{8}{cx^d})\)

= \(\lim_{x \to \infty} \frac{a}{cx^(d-b)} + \lim_{x \to \infty} \frac{8}{cx^d}\)                          ...............(since d > b)

Answer:

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.

Wavelength of light = velocity of light / frequency of light
