Answer:

f(x) = 100 (3)^x  <===> C

f(x) = 100 (3.5)^x  <===> B

f(x) = 100 (4)^x <===> A

Step-by-step explanation:

Since the base of each of the exponential functions is the same, the higher the base, the higher up the graph will be with respect to another base with a lower value

This can be easily determined by choosing a specific value for x for each equation and seeing what the f(x) value is

Let's choose x = 2

For f(x) = 100 (3)^x, at x = 2 we get f(2) = 100(3)^2 = 100 x 9 = 900

For f(x) = 100 (3.5)^x, at x = 2 we get f(2) = 100(3.5)^2 = 100 x 12.25 = 12.25

For f(x) = 100 (4)^x, at x = 2 we get f(2) = 100(4)^2 = 100 x 16 = 1600

So for a specific value of x, the higher the base, the higher the graph is relative to the x-axis

So the matches are:

f(x) = 100 (3)^x  <===> C

f(x) = 100 (3.5)^x  <===> B

f(x) = 100 (4)^x <===> A

The table that represents the equation of the proportional relationship is; Table 4

A proportional relationship is defined as a mathematical relationship that exists between two variables in which their ratio is always equal.

We have that the equation s equals three fourths times f. This is expressed as;

s = ³/₄f

where;

s is the amount of sugar

f is the amount of flour

Table 1;

when f = 1

s = ³/₄(1)

s = ³/₄

when f = 2

s = ³/₄(2)

s = 6/4

In order to determine the practical significance requires considering both the effect size measures and the context of the study

One way to determine practical significance is by using effect size measures. Effect size is a standardized measurement of the magnitude of a treatment or intervention.

A common equation used to calculate effect size is Cohen's d, which is the difference between the means of two groups divided by the standard deviation.

Another equation used is the odds ratio, which is the ratio of the odds of an event occurring in one group compared to another.

Additionally, it is important to consider the context of the study when evaluating practical significance.

The limit of f(x) as x approaches positive infinity and negative infinity is equal to 3/4, and the horizontal asymptote of the function is y=3/4.

The horizontal asymptote of a function is a horizontal line that the function approaches as x approaches infinity or negative infinity.

The function f(x) is given by

=> f(x)= 3x³ + 8/4x³ + √ 64x⁶⁴.

To evaluate the limits, we need to consider what happens as x approaches positive infinity and negative infinity.

In this case, as x approaches positive infinity or negative infinity, the x³ term in the numerator and denominator will dominate and the limit of the function will be equal to 3/4.

This means that the function has a horizontal asymptote of y=3/4.

The heights of the bars of a histogram correspond to the frequency of values within the data set.

A histogram is used to illustrate the distribution of data within a set by showing the number of data points that fall within a specified range of values (called bins).

The height of each bar in the histogram represents the frequency of values within the bin range. A taller bar indicates that more data points fall within that range. The area of each bar is also proportional to the frequency of the values in the bin.

The system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.

The stability of a linear system can be determined by analyzing the magnitude of its impulse response −

The number of tones of the black plastic that is required here is 9567.3 tones .

The volume of one meter of piping can be calculated as follows:

V = π * (r^2) * l

Where r is the radius of the pipe (6.5 mm), and l is the length (1 meter).

So, the volume of one meter of piping is:

V = π * (6.5^2) * 1 = 134.96 mm^3

Since 1 m^3 = 10^9 mm^3, the volume in m^3 of one meter of piping is:

V = 134.96 / 10^9 = 0.00013496 m^3

Therefore, the total volume of 81000 km of piping is:

V = 0.00013496 * 81000 * 10^3 = 11,124.16 m^3

the data y = (y1,..., yn) are a sample from a normal distribution with unknown mean θ and known standard deviation σ = 2. Our prior distribution p(θ) is normal with mean 0 and standard deviation σ0.

y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1 y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1

We have two cases for Ф,

1.  Ф=1; it implies that Pr(Ф=1)=0.5, while y~N(1,α²)

2. Ф=2; it implies that Pr(Ф=2)=0.5, while y~N(2,α²)

Now,

For 1st case of α=2,

We have marginal probability density formula

p(y)=∑p(yIФ)p(Ф)

=p(yIФ=1)p(Ф=1)+p(yIФ=2)p(Ф=2)

=N(yI1,2²)(1/2)+N(yI2,2²)(1/2)

=(1/2)[N(yI1,2²)+N(yI2,2²)]

Now.

For Pr(Ф=1Iy=1) at α=2

We have,

=p(Ф=1Iy=1)

=[p(y=1,Ф=1)]/[p(y=1)]

=[p(y=1IФ=1)p(Ф=1)]/[p(y=1)]

={(1/)exp[(-1/(2*2²))(1-1)²(1/2)]}/{(1/)(1/2)[exp[(-1/(2*2²))(1-1)²]+exp[(-1/(2*2²))(1-2)²]}

=0.53 Answer

Now, to describe the changes in shape of Ф when α is increased and decreased deviation

The formula for posterioir density is p(ФIy)=p(yIФ)p(Ф)/p(y)

=exp[(-1/(2α²)(y-Ф)²]/{exp[(-1/(2α²)(y-1)²]+exp[(-1/(2α²))(y-2)²]}

Now at Ф=1 and solving the equation, we get

p(Ф=1Iy)=1 / {1+exp[(2y-3)/2α²]}

Similarly at Ф=1 and solving the equation, we get

p(Ф=2Iy)=1 / {1+exp[(2y-3)/2α²]}

Conclusion:

α² → ∞ ⇒p(ФIy) → p(Ф) = 1/2

α² → 0 ⇒ two cases

The solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:

What is inequality?

A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is the set of all solutions.

We can solve this absolute value equation by first isolating the absolute value term on one side of the equation and then solving for both possible cases. Here are the steps:

|4 − 2x| + 6 = 18

|4 − 2x| = 12 (subtract 6 from both sides)

Now we have an absolute value equation with no constant term. We can split this equation into two cases: one where the expression inside the absolute value is positive, and one where it is negative. For each case, we can solve for x:

Case 1: 4 - 2x > 0

If 4 - 2x is positive, then we can drop the absolute value bars and write:

4 - 2x = 12

-2x = 8

x = -4

So one solution is x = -4.

Case 2: 4 - 2x < 0

If 4 - 2x is negative, then we must flip the inequality when dropping the absolute value bars:

-(4 - 2x) = 12

-4 + 2x = 12

2x = 16

x = 8

So the other solution is x = 8.

Therefore, the solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:

[tex]\boxed{21.691} \; feet[/tex]

Step-by-step explanation:

See attached figure

The power cable going south first by 50 feet and then going west by 30 feet form the legs of a right triangle.

The diagonal which is the shortest distance between start and end points can be computed by the Pythagorean theorem

[tex]c^2 = a^2 + b^2[/tex]

where c is the hypotenuse and a, b the other two sides

Plugging in values for a = 50 and b = 30 we get

[tex]c^2 = 50^2 + 30^2\\\\c^2 = 2500 + 900\\\\c^2 = 3400\\\\c = \sqrt{3400}\\\\c = 58.3095 \;feet[/tex]

The cable length if going south and then west will be 50 + 30  = 80 feet

So cable length saved = 80 - 58.3095 = 21.6905

Rounded to 3 decimal places this would be 21.691 feet

Answer:

By using the Pythagorean Theorem, we can calculate that the diagonal of the city block is approximately 58.3 feet long. This means that the power company could save 7.3 feet of powerline cable by running the powerlines across the diagonal of the city block, instead of around the south and west sides.
