Step-by-step explanation:
Slope intercept form is written as y = mx + b, where m is the slope and b is the y- intercept.

1.50y = -2.00x + 15

[tex]2 \log_{a}(2x-1)=\log_{a}(2x-1)^{2}[/tex]

So the expression can be expressed as a single logarithm as follows:

here is a list 31 29 33 37 43 38 33 40 find the mode in number of list and work out on mean
Answers
Answer: Mode = 33, Mean = 35.5
Step-by-step explanation: The mode is whatever number appears the most.
To find the mode, first put the numbers in order from least to greatest.
29, 31, 33, 33, 37, 38, 40, 43
In this case, 33 appears the most, so the mode is 33.
The mean is the average of all of the numbers.
Firstly, add up all of the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
Now that you have all of them added up, divide the final sum by the number of numbers you have in the list. In this case, you have 8 numbers.
284/8 = 35.5
Your mean is 35.5
Answer:
Mode = 33
Mean = 35.5
The mode is whatever number appears the most.
to find the mean:
add all the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
divide that by the number of numbers you have in the list.
284/8 = 35.5
mean = 35.5

Write an equation for a polynomial with all the following features:
a. The degree is 5.
b. The polynomial has 4 terms.
c. The graph of the polynomial crosses the vertical axis at Y = 12 .
Identify the approximate input values of any relative maximums and minimums of this 5th degree polynomial.
Answers
Answer:
Step-by-step explanation:
(x-1)^5 = x^5 - 5x^4 + 15x^3 - 15x^2 + 5x - 1
That has 6 terms, so let's get rid of the two middle ones.
f(x) = (x-1)^5 - 15x^2(x-1)
Now, f(0) = 1, but we want f(0) = 12
So, let
f(x) = 12((x-1)^5 - 15x^2(x-1)) = 12x^5 - 60x^4 + 60x - 12
As for the graph, it looks like
y = (x+4)(x+2)(x-1)^2(x-6)
The extrema appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)
The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The degree of the polynomial is 5.
The polynomial has 4 terms
So (x-1)⁵ = x⁵ - 5x⁴ + 15x³ - 15x² + 5x - 1
Let's eliminate the two middle terms from it, which has six.
f(x) = (x-1)⁵ - 15x²(x-1)
Given that the graph of the polynomial crosses the vertical axis at Y = 12
So, substitute f(0) = 1, but we determine f(0) = 12
So, let f(x) = 12((x-1)⁵ - 15x²(x-1)) = 12x⁵ - 60x⁴ + 60x - 12
As for the graph, it looks like
So the approximate input values of relative maximums and minimums of this 5th-degree polynomial :
y = (x+4)(x+2)(x-1)²(x-6)
The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)

If f(x)=1−x² and g(x)=x²−1, then for which of the following values of b does
f(3b)+8=g(3b)−8?
A) 1
B)√8
C) 8
D) √3
E) 0
Answers
Answer:
A
Step-by-step explanation:
We have the two functions: [tex]f(x)=1-x^2[/tex] and [tex]g(x)=x^2-1[/tex].
And we want to find the value of b such that [tex]f(3b)+8=g(3b)-8[/tex] is true.
Notice that we can multiply f(x) by -1. This yields:
[tex]-f(x)=x^2-1[/tex]
Notice that this is the same as g(x). Therefore:
[tex]-f(x)=g(x)[/tex]
If we substitute 3b for x:
[tex]-f(3b)=g(3b)[/tex]
So, we can go back to our equation. We have:
[tex]f(3b)+8=g(3b)-8[/tex]
Substitute -f(3b) for g(3b):
[tex]f(3b)+8=-f(3b)-8[/tex]
Solve. Subtract 8 from both sides and add f(3b) to both sides:
[tex]2f(3b)=-16[/tex]
Divide both sides by 2:
[tex]f(3b)=-8[/tex]
Now, we can use the function of f(x). Substitute 3b into f(x). So:
[tex]1-(3b)^2=-8[/tex]
Subtract 1 from both sides:
[tex]-(3b)^2=-9[/tex]
Divide both sides by -1:
[tex](3b)^2=9[/tex]
Take the square root of both sides:
[tex]3b=\pm 3[/tex]
Divide both sides by 3. So, the value of b can be:
[tex]b=-1, 1[/tex]
Therefore, our answer is A.
And we're done!
Answer:
A.1
Step-by-step explanation:
f(x) = 1 - x² ⇒ f(3b) = 1 - (3b)² = 1 - 9b²
g(x) = x² - 1 ⇒ g(3b) = (3b)² - 1 = 9b² - 1
f(3b) + 8 = g(3b) - 8 ⇒ (1 - 9b²) + 8 = (9b² - 1) - 8
⇔ 9 - 9b² = 9b² - 9
⇔ 9 + 9 = 9b² + 9b²
⇔ 18 = 18b²
⇔ b² = 1
⇒ b = 1; - 1

2y = 9
y=4.5
Answer:
[tex]\boxed{(0 , 4.5)}[/tex]
Step-by-step explanation:
→ Rearrange into y = mx + c format
2y = - 3x + 9
→ Divide everything by 2
y = -1.5x + 4.5
→ Substitute x = 0
y = 0 + 4.5 ⇒ 4.5

The women’s heptathlon in the Olympics consists of seven track and field events: the 200-m and 800-m runs, 100-m high hurdles, shot put, javelin, high jump, and long jump. In the 2000 Olympics, the best 800-m time, run by Gertrud Bacher of Italy, was 8 seconds faster than the mean. The winning long jump by the Russian Yelena Prokhorova was 60 centimeters longer than the mean. Bacher’s winning 800-m time of 129 seconds was 8 seconds faster than the mean qualifying time of 137 seconds (the standard deviation of the qualifying times was 5 seconds). Prokhorova’s winning long jump was 60cm longer than the average 6-m jump (Note: the standard deviation of the long jumps was 30 cm). Which performance is more outstanding (and hence deserves more points when computing their overall score)? Explain.
Answers
Answer: Prokhorova is more outstanding.
Step-by-step explanation: To compare scores from different distributions, first standardize it:
z-score = [tex]\frac{x-\mu}{\sigma}[/tex]
where
x is the individual mean you want to compare
μ is the mean of the population
σ is standard deviation
For Gertrud Bacher:
z-score = [tex]\frac{129-137}{5}[/tex]
z-score = [tex]-1.6[/tex] (s)
The negative sign indicates Bacher's mean is less than the mean
For Yelena Prokhorova:
z-score = [tex]\frac{660-600}{30}[/tex]
z-score = 2 (cm)
The positive sign indicates Prokhorova's mean is more than the mean.
Using z-score table, you determine the percentiles are:
For Bacher: Percentile = 5.5%
For Prokhorova: Percentile = 97.7%
Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.
