The x-intercept and the asymptote of g(x) are x = 5 and x = 4, respectively
How to determine the x-intercept and asymptote of g(x)?The equation of the function is given as:
g(x) = log3 (x - 4)
Set the function to 0, to determine the x-intercept
log3 (x - 4) = 0
Express the function as an exponential function
x - 4 = 3^0
Evaluate the exponent
x - 4 = 1
Add 4 to both sides
x = 5
Set the radical to 0, to determine the asymptote
x - 4 = 0
Add 4 to both sides
x = 4
Hence, the x-intercept and the asymptote of g(x) are x = 5 and x = 4, respectively

Voluntary sampling is one type of sampling method that is not probability based. this means that
Voluntary sampling is one type of sampling method that is not probability based this means that the survey's findings cannot be reliably extrapolated or generalized.
What is voluntary sampling?
A sample made up of people who freely decided to take part in the sample group is known as a voluntary sampling. Those who want to participate in a voluntary sampling typically do so because they are passionate about the topic of the survey. According to definitions, a sample with self-selected individuals is one that includes voluntary responses.
Researchers who wanted to be able to generalize their findings to the entire community would not choose volunteer sampling because it does not produce a representative sample.
A convenience sample is one that the researcher can use at their discretion, such as voluntary sampling.
However, because only those who have strong opinions about the poll will typically agree to participate, voluntary sampling can result in bias.
The survey's findings cannot be confidently extrapolated or generalized because of the possibility of bias.

Answer:
A ≈ 75 in²
Step-by-step explanation:
the area (A) of the circle is calculated as
A = πr² ( r is the radius )
here r = 5 and using 3 for π , then
A = 3 × 5² = 3 × 25 = 75 in²
Answer:
75 in^2
Step-by-step explanation:
Since the formula to find the area of a circle is already up, we can use that to solve the question.
The image gave us the value of the radius right away, so the question will be a lot easier to solve.
--> The reason why the radius is needed is that the 'r' in the formula means radius. We need the value of the radius to find the area of the circle.
Now, we can just replace r with 5.
--> A = 25 [tex]\pi[/tex]
Since the question told us to replace [tex]\pi[/tex] with 3, we can do that.
--> A = 25 x 3
--> A = 75
We can conclude that the area of the circle is 75 in^2.

1. Graph the following sample data set showing the distance covered by a runner
during an 800 meter race.
A graph for the data (time and distance) shown in the given table is plotted in the image attached below.
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
This ultimately implies that, the data of a linear graph are directly proportional and as such as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.
In this exercise, you're required to plot a graph for the data (time and distance) that are recorded for an object that is starting from rest.
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:

PLEASE HELP! ……………..
Step-by-step explanation:
I am not sure I can read the original expression right, the picture is too blurry for the small digits.
is it 3^(5/5) ?
or rather 3^(5/6) ?
in any case, you should know that a number written like this always has the structure
a^(b/c)
so,
a = 3
b = 5 (or whatever is the numerator or top of the fraction)
c = 5 (or whatever is the denominator or bottom of the fraction).
the denominator of a fraction in an exponent gives us the grade of root to be taken.
the numerator gives us the power of the base number.
and if the exponent is negative it would mean that the whole thing is a 1/... fraction.

The midpoint between A and E is (0,1)
How to determine the midpoint between A and E?The coordinates of the cities are given as:
A(-2,3), B(2,7), C(7,8), D(6,3) and E(2,-1).
From the above, we have:
A = (-2,3)
E = (2,-1)
The midpoint between A and E is calculated using
Midpoint = 1/2 * (x1 + x2, y1 + y2)
Substitute the known values in the above equation
Midpoint = 1/2 * (-2 + 2, 3 - 1)

How many ways are there to put five beads on a necklace if there are eight distinct beads to choose from, and rotations and reflections of the necklace are considered the same
Answer:
3,360
Step-by-step explanation:
so, to start with, there are 8 over 5 permutations (the sequence of the picked beads matters, but no repetitions of beads are possible) to pick 5 items out of 8 available ones.
that is
8! / ((8-5)!) = 8! / 3! = 8×7×6×5×4 = 6,720
rotations and reflections are the same thing here for a 1- dimensional sequence.
1 2 3 4 5 rotated around the middle (3) is
5 4 3 2 1
a reflection is again
5 4 3 2 1
so, we need to consider that instead of 8 beads for the first choice we have only 4 beads to choose from to leave the other 4 beads as choices for the last position.
once we have this established, it is sure that the first and the last position cannot have mirrored beads in any permutation. and therefore rotational or reflectional permutations are impossible.
in other words, half of the possible permutations would be rotations/reflections, and we need to eliminate them.
so, the calculation is
4×7×6×5×4 = 8×7×6×5×4/2 = 6,720/2 = 3,360

Calculate angles in a triangle
Step-by-step explanation:
Total Angle in a triangle is 180°
so D = 140 + 25 = 165°
D = 190° - 165° = 15°
Your answer is 15°.
Answer:
angle d = [tex]\boxed{15}^ {\circ}[/tex]
Step-by-step explanation:
The angles in a triangle add up to 180°.
∴ ∠d + 25° + 140° = 180°
⇒ ∠d + 165° = 180°
⇒ ∠d = 180° - 165°
⇒ ∠d = 15°

If 2x + 5 ≤ 9, what is the greatest possible value of
2x - 5 ?
Answer:
-1
Step-by-step explanation:
Since we have the linear equation, 2x-5, and it's increasing since the slope is positive, that means we want the maximum x-value, to find the maximum y-value, or possible value.
This means, we want to find the maximum x-value of 2x+5 that is less than or equal to 9, and since we want the maximum x-value, we want the right side to also be the maximum, and since we have a less than or equal to symbol, we can have the equation equal to 9, which is the make value. So we get the following equation
[tex]2x+5=9\\[/tex]
Subtract 9 from both sides
[tex]2x=4[/tex]
Divide both sides by 2
[tex]x=2[/tex]
This is the maximum x-value we can get from the inequality, and now we plug this into the equation 2x-5
[tex]2(2)-5[/tex]
4-1
-1
So the maximum value is -1

What is cost ?
Cost denotes the amount of money that a company spends on the creation or production of goods or services. It does not include the markup for profit. From a seller's point of view, cost is the amount of money that is spent to produce a good or product.
Cost of playing = $2
Expected return
10% chance to win $1 = $1 10% = $0.1
25% chance to win back $2 = $2 25% = $0.5
50% chance to win $5 = $5 50% = $2.5
15% chance to lose $2 (being cost) = $2 15% = ($0.3)
= $0.1 + $0.5 + $2.5 - $0.3 = $2.8
Now for this we have to pay fixed cost $2
Thus, expected value of playing game = $2.8 - $2 = $0.8
