What is the equation of the axis of symmetry for the parabola y equals start fraction one over three end fraction left parenthesis x plus one right parenthesis squared minus three?
Answers
Explanation:
Our equation is
[tex]y=\frac{1}{3}(x+1)^2-3[/tex].
This is in vertex form, which is
y = a(x-h)² + k, where (h, k) is the vertex.
In our equation, h corresponds with -1 and k corresponds with -3, making the vertex (-1, -3).
The axis of symmetry is the x-coordinate of the vertex; this makes the axis of symmetry for this equation x = -1.
the slope of a line is negative 1 / 5 and the y-intercept is 5 what is the equation of the line written in general form
Answers
Answer;
= x + 5y -25 =0
Explanation;
Thee equation of a line in general form is ;
Ax + By + C = 0
Where A, B and C are integers.
The equation of a line in slope-intercept form is
y = mx + b ; where m is the slope and b is the y-intercept
In this case; m = -1/5 and b =5
thus; y = -1/5 x + 5 (the slope-intercept form)
y = -1/5 x + 5
Multiplying all terms by 5
5 y = -x + 25
= x + 5 y - 25 = 0 (in general form)
A magazine published a list consisting of the state tax on each gallon of gas. If we add the 50 state tax amounts and then divide by??? 50, we get 27.3 cents. Is the value of 27.3 cents the mean amount of state sales tax paid by all U.S.??? drivers? Why or why??? not?
Answers
To find the mean, we divided by 50 because there are 50 states. However, the number of people in each state is not equal. Therefore, the 50 states should not be treated as they are equal.
To find the mean correctly, we would have to find weight the value of each state according to the number of people in the state.

Samuel paid $720 for a new music system. The list price for the music system was $800. What was his rate of discount?
Answers
Samuel received a 10% discount on the music system, calculated by finding the difference between the list price ($800) and the sale price ($720), then dividing that by the list price and multiplying by 100.
Explanation:The question at hand is about calculating the rate of discount Samuel received on his new music system. Initially, the list price of the music system was $800, but Samuel paid $720 for it. To find the rate of discount, we first need to determine the discount amount which is the difference between the list price and the sale price.
List Price = $800Sale Price = $720Discount Amount = List Price - Sale Price = $800 - $720 = $80Next, to find the rate of discount, we use the formula:
Rate of Discount = (Discount Amount / List Price) × 100
Substituting the values we have:
Rate of Discount = ($80 / $800) × 100 = 10%
Therefore, Samuel received a 10% discount on the music system.
Claire created a pie chart to show how she spent her time on Monday She spent 8 hours at school, 4 hours playing basketball, 2 hours doing homework, 8 hours sleeping, and 2 hours doing chores. Which statements describe how the pie chart will look? Check all that apply
Answers
The pie chart showing Claire's daily activities will have five sections representing school, basketball, homework, sleeping, and chores. Each section will portray the fraction of 24 hours that she spends on that activity. For example, School and Sleeping will both occupy 1/3 of the pie chart each.
Explanation:The subject in question is related to pie charts in Mathematics, specifically fractions and percentages. Claire has a total of 24 hours in the day and her activities are school for 8 hours, basketball for 4 hours, homework for 2 hours, sleep for 8 hours, and chores for 2 hours. In the pie chart, her spent time in a day can be shown as fractions of the total time, 24 hours.
For instance, Claire spent 8/24 or 1/3 of her time at school; the pie chart will show a section occupying 1/3 of the circle representing this. Similarly, she spent 4/24 or 1/6 of her time playing basketball, 2/24 or 1/12 of her time doing homework, 8/24 or 1/3 of her time sleeping, and 2/24 or 1/12 of her time doing chores. Each of these fractions will be a section on the pie chart. Hence, the chart will have five different sections, each representing a different activity.

Which image that would portray the rotation of the given preimage and the rotation arrow.
Pre-image (1st picture shown):
Image (the following 4 pictures are the options):
Answers
Answer:
First figure as shown below is the correct option.
Step-by-step explanation:
We are given that,
The pre-image is rotated in the direction of the arrow to form an image.
It is required to find the image formed.
Since, the arrow is rotating counter-clockwise, we get that,
The star in the pre-image will rotate upwards towards the left.
So, according to the options, we have,
The first image where the star is at the highest height will be the image after rotating the pre-image.
Hence, the first figure as shown below is the correct option.
Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3).
Answers
The first thing I'll do is solve "5y = 2x + 20" for "y=", so that I can find my reference slope:
y = (2/5)x + 4;
So the reference slope from the reference line is m = 2/5;.
Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line.
Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope m = 2/5. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);
Finally, y = (2/5)x + 17/5;

Answers
Therefore, your answer is A because there is an x to the 5th power, and three different components (3, -7x^5, and x^2)
Answer: The answer you are looking for is option A which would be 3 - 7x^5 +x^2
Step-by-step explanation: It is a 5th degree trinomial because, there are three terms in this equation being 3, 7x^5, and x^2; this makes it a trinomial becuase there are three terms. What makes this a 5th degree is the fact that the highest exponet is 5.
Darrin lives in Washington, D.C., which has a sales tax of 6%. He just bought a video camera whose full price was $620, but after sending in a rebate form, he later received a check in the mail for $95. What was the total amount that Darrin ended up paying after receiving the rebate? A.$562.20 B.$556.50 C.$525.00 D.$657.20
Answers
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Cost of video camera = $620
Rate of sales tax = 6%
Amount of sales tax is given by
[tex]\dfrac{6}{100}\times 620\\\\=\$37.2[/tex]
Total amount after sales tax is given by
[tex]\$620+\$37.2\\\\=\$657.20[/tex]
Amount of rebate = $95
So, final amount that Darrin ended up paying after receiving the rebate is given by
[tex]\$657.20-\$95\\\\=\$562.20[/tex]
Hence, option 'A' is correct.
Which number produces an irrational number when added to 0.4
Answers
To find an irrational number when added to 0.4, you need to add an irrational number. One example is adding the square root of 2 to 0.4.
To find a number that produces an irrational number when added to 0.4, let's consider a rational number like 0.6.
Irrational numbers are infinite in nature and cannot be represented accurately as a finite decimal or fraction. They exist along with rational numbers, forming the set of real numbers on the number line.
0.4 + 0.6 = 1, which is rational.Rational + Irrational = Irrational, so to get an irrational number, you need to add an irrational number.One example of an irrational number you can add to 0.4 to get irrational is √2 - 0.4, where √2 is irrational.8x+10=12x-18

out of a port departed a steam boat with a speed of 36.8km/h. In 1.75 hours out of the same port and going the Sam direction departed a speed boat. In 1.8 hours after the the department of the speed boat, the distance between the speed boat and the steam boat was 86.9km. What was the speed boats speed in km/h?
Answers
steam boat:
r1 = (36.8) * t
speed boat:
r2 = v * (t-1.75)
The distance between the boats is:
d = r2-r1 = v * (t-1.75) - (36.8) * t
Substituting t = 1.8 and d = 86.9 we have:
86.9 = v * (1.8-1.75) - (36.8) * 1.8
We clear the speed:
v = (86.9 + (36.8) * 1.8) / ((1.8-1.75))
v = 3062.8 Km / h
Answer:
the speed boats speed in km / h is:
v = 3062.8 Km / h
Answer: the speed boats speed in km / h is:
v = 3062.8 Km / h
