The statement A is correct option.
What is the vertex of a quadratic function?The vertex of a quadratic equation is the minimum or maximum point of the equation.
Given that, the quadratic function f(x) has a vertex at (1, 6) and opens downward and g(x) = (x - 7)² + 1,
The vertex of f(x) is at (1, 6), we know that a vertical line passing through the vertex is called the axis of symmetry for the parabola.
That mean, axis of symmetry will pass through (1, 6)
Therefore, the axis of symmetry for f(x) is x = 1
And, g(x) = (x - 7)² + 1
= x²+49-14x+1
= x²-14x+50
Vertex = -b / 2a
here, b = -14 and a = 1
Vertex (h, k) = 14 / 2 = 7
To find k, put x = 7 in the equation,
(7-7)²+1 = 1
Therefore, point of the vertex = (7, 1)
That mean axis of the symmetry will pass through (7, 1)
Therefore, axis of the symmetry for g(x) = 7
Hence, the statement A is correct option.

The complete equation is 3 lb/sec ≈ 4897.0806 kg/h.
How to complete the conversionFrom the question, we have the following parameters that can be used in our computation:
3 Ib/sec ≈ ? kg/h
To convert pounds per second (lb/sec) to kilograms per hour (kg/h), we can use the conversion factor: 1 lb = 0.45359237 kg.
So, 3 lb/sec = 3 * 0.45359237 kg/sec = 1.361 kg/sec
To convert from per second to per hour, we multiply by the number of seconds per hour:
1.3607771 kg/sec * 3600 sec/hour = 4897.0806 kg/h
Therefore, 3 lb/sec ≈ 4897.0806 kg/h.

In Bill the Boring's dryer there are 3 black shirts, 8 gray shirts, 13 black sweaters, and 7 gray sweaters. Bill is going to take one of these pieces of clothing out
of the dryer at random to check if his clothes are completely dry. What is the probability that the piece of clothing Bill takes out is gray or is a shirt?
Do not round intermediate computations, and round your answer to the nearest hundredth.
Answer:
0.58
Step-by-step explanation:
First, we need to find the total number of pieces of clothing in the dryer. We do this by adding up the number of black shirts, gray shirts, black sweaters, and gray sweaters: 3 + 8 + 13 + 7 = 31
Next, we need to find the number of gray pieces of clothing in the dryer. We do this by adding up the number of gray shirts and gray sweaters: 8 + 7 = 15
Now we can find the probability of Bill taking out a gray piece of clothing by dividing the number of gray pieces of clothing by the total number of pieces of clothing: 15/31
To find the probability of Bill taking out a shirt, we add the number of black shirts and gray shirts: 3 + 8 = 11
Now we can find the probability of Bill taking out a shirt by dividing the number of shirts by the total number of pieces of clothing: 11/31
To find the probability that the piece of clothing Bill takes out is gray or is a shirt, we add the probability of Bill taking out a gray piece of clothing and the probability of Bill taking out a shirt.
So the probability that the piece of clothing Bill takes out is gray or is a shirt is: (15/31)+(11/31)= 0.58 rounded to the nearest hundredth.

and-a-half for her overtime hours. what are her bi-weekly gross earnings if she works
47 hours during a week of her pay period?
Her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.
How is this determined?The answer is determined by calculating the income earned for the additional hours she works multiplied by the income earned for the additional hours. This is then added with the gross income for the week and the total is calculated by taking the sum of the two.
Given that her bi-weekly gross earnings are $913.45, and she earns additional compensation for all hours over 40 worked in one week.
For 47 hours, the extra hours worked are 7.
Hence, the compensation for additional hour is:
a = 7 (913.45/2)
a = 3197.075
The gross income would be:
Total = bi-weekly pay + additional hours
T = 913.45 + 3197.075
T = 4110.525
Hence, her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.

The "=" sign determines on both sides must always be present when writing an equation.
Given data,
Let the equation be represented as A
Now, the value of A is equal to the original amount of money
The amount Ofelia spends = $ 12
The remaining amount of money Ofelia had=(1/5)A
So, the equation will be
subtract the original amount of money A - amount Ofelia spends = remaining amount of money Ofelia had
By substituting the values in the equation, we get
A - 12 = ( 1/5 )A
Add 12 on both sides of the equation, and we get
A = (1/5)A + 12
Subtract (1/5 )A on both sides of the equation, and we get
A - ( 1/5 )A = 12
On simplifying the equation, we get
(5A - A)/5 = 12
4A/5 = 12
Multiplying by 5 on both sides of the equation, we get

Which is the smallest number?13,0.13,1.03,1.3
Answer: the smallest number out of the four is 0.13
Step-by-step explanation:
First, let's think about the number 13. It's a whole number and it's pretty big. It's definitely larger than the other numbers we're looking at today.
Next, let's take a look at 0.13. This number is a decimal, which means it's a number that has a whole number part and a fractional part. The whole number part is 0 and the fractional part is 13. So, 0.13 is smaller than 13.
Now, let's move on to 1.03. This is also a decimal and it's a little bit bigger than 0.13, but smaller than 13.
Finally, we have 1.3. This number is a decimal with a whole number part of 1 and a fractional part of 3. It is bigger than 0.13 and 1.03 but smaller than 13.
So, we can see that the smallest number out of the four is 0.13.

what is the minimum z score a data point could have to remain in top 25 percent
The top 25 percent, a data point would need to have a z score greater than 0.67.
A z score is a measure of how many standard deviations a data point is from the mean of a data set.
To determine the minimum z score, we first need to find the mean and standard deviation of the data set. The mean represents the center of the data and the standard deviation tells us how spread out the data is.
If a data point has a z score greater than 0, it is above the mean and considered in the top half of the data set.
To be in the top 25 percent, the data point would need to have a z score greater than the value that separates the top 75 percent from the bottom 25 percent.
This value can be found using a table of standard normal distributions or using software that calculates z scores.
In a standard normal distribution, the value that separates the top 75 percent from the bottom 25 percent is about 0.67.

this question is designed to be answered without a calculator., what are the one-sided limits of f(x) at x = 1?
one-sided limits of a function f(x) at x = 1 is lim x → 2[f(x) - f(2)]/(x - 2) = 20
Since function f(x) = 5(x² - 1) and we want to find its derivative, we can proceed thus.
Let x = h + 2
So,
f(x) = 5(x² - 1)
f(2) = 5[(2)² - 1]
= 5[4 - 1]
= 5(3)
= 15
f(2 + h) = 5[(2 + h)² - 1)
= 5(4 + 4h + h² - 1)
= 5(3 + 4h + h²)
= 15 + 20h + 5h²
So, f(2 + h) - f(2) = 15 + 20h + 5h² - 15
= 20h + 5h²
So, we have that
[f(2 + h) - f(2)]/h = (20h + 5h²)/h
= 20 + 5h
Now, taking the limit as h → 0, we have
= 20 + 5(0)
= 20 + 0
= 20
So, lim h → 0[f(2 + h) - f(x)]/h = lim x → 2[f(x) - f(2)]/(x - 2) = 20
So, lim x → 2[f(x) - f(2)]/(x - 2) = 20

If ABC is a right angled triangle and angle BAC = 90°. If AD perpendicular to BC and BD=DC then BC² = 4AD² is 4 * AD^2.
How to prove that BC² = 4AD²?
In right triangle ABC, by Pythagorean theorem, we have:
AC^2 + BC^2 = AB^2
Since AD is perpendicular to BC, by similarity, triangle ABD is similar to triangle ADC. Therefore, we have:
BD/AD = AD/DC
BD = AD^2/DC
Substituting BD into the first equation, we get:
AC^2 + BC^2 = AB^2 = AD^2 + (AD^2/DC)^2
AC^2 + BC^2 = AD^2 + AD^4/DC^2
AC^2 + BC^2 = AD^2(1 + AD^2/DC^2)
Since BD = DC, we have:
AC^2 + BC^2 = AD^2(1 + AD^2/BD^2)
And substituting DC = BD:
AC^2 + BC^2 = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2) = AD^2(1 + AD^2/BD^2)
Since AB^2 = AC^2 + BC^2, we have:
BC^2/AD^2 = AB^2/AD^2 - AC^2/AD^2 = (AB^2 + AC^2)/AD^2 - AC^2/AD^2 = (BC^2 + AC^2)/AD^2 = 4
Therefore, BC^2 = 4 * AD^2.
