how do you find the axis of symmetry?
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.
A cylinder has a circumference of 16 \pi inches and a height of 20 inches. What is the surface area of the cylinder in terms of \pi ?

The purchase price of Wynona’s boots is 85.5% of the original price.
It is given that
The marked price of boots = $85.79
What is the percentage?The percentage is a relative value indicating the hundredth parts of any quantity.
Price after a discount of 10% = \(85.79 - 85.79*10/100 = 77.211\)
Price after another discount of 5% = \(77.211-77.211*5/100 = 73.35\)
\(\frac{PurchasePrice}{OriginalPrice}*100 =\frac{73.35}{85.79}*100 = 85.5\)

A valid study Group of answer choices uses random sampling. results in a causal relationship between the independent and dependent variables. portrays the population being studied. measures what it is supposed to. verifies expected results.
A valid study is one that portrays the population being studied and measures what it is supposed to. It must use random sampling and produce expected results to be deemed a reliable source. However, such studies do not necessarily result in a causal relationship between the independent and dependent variables.
The primary goal of any study is to depict the population being investigated in an accurate and unbiased manner. This involves selecting an appropriate sample of the population to study. This is why a study must use random sampling, which means every member of the population has an equal chance of being selected. This helps avoid sample bias, which is when a sample is chosen in a way that it is not representative of the population, leading to incorrect or inaccurate conclusions.
A valid study must measure what it is supposed to, which means that the study should be designed to measure what it claims to measure. For instance, a study on the effects of sleep on memory should use measures that accurately assess memory and sleep. If the study is designed to assess memory but fails to do so, the results will be unreliable. Finally, a valid study verifies expected results.
This means that the study should produce results that are consistent with what is expected based on prior research or theory. However, this does not mean that a study necessarily results in a causal relationship between the independent and dependent variables. Rather, such a relationship can only be inferred if the study is well-designed and the results are properly analyzed and interpreted.

Step-by-step explanation:
likert-type scale response choices must be balanced at the ends of the response continuum.
that it is important for likert-type scale response choices to be balanced at the ends of the response continuum. This means that there should be an equal number of positive and negative response options to avoid any bias or skew in the results.
An explanation for this is that if there are too many positive or negative response options, respondents may feel pressured to choose a certain option even if it doesn't accurately reflect their true opinion. This can result in inaccurate data and can skew the results of the survey or study.
balancing the response choices on a likert-type scale is crucial for obtaining accurate and unbiased data. By having an equal number of positive and negative options, respondents are more likely to provide honest and accurate responses.

Vernon's work for finding the value of x is shown below. Lines A C and B D intersect at point E. Angle A E D is (16 x + 8) degrees and angle D E C is 76 degrees. Step 1: 16x + 8 = 76 Step 2: 16x = 68 Step 3: x = 4.25 Did Vernon solve for the correct value of x? If not, explain where he made his error. Yes, he solved for the correct answer. No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other. No, he should have added 8 to both sides rather than subtracting 8 from both sides. No, he should have multiplied both sides by 16 rather than dividing both sides by 16.
Answer:
No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other
Step-by-step explanation:
Find the diagram attached
If line AC and BD intersects, then m<AED + m<DEC = 180 (sum of angle on a straight line is 180 degrees)
Given
m<AED = 16x+8
m<DEC = 76 degrees
16x + 8 + 76 = 180
16x + 84 = 180
16x = 180-84
16x = 96
x = 96/16
x = 6
Hence the value of x is 6
Hence the correct option is No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other
Answer:
b is correct
Step-by-step explanation:
Yes, he solved for the correct answer.
✔No, he should have set the sum of ∠AED and ∠DEC equal to 180°, rather then setting ∠AED and ∠DEC equal to each other.
No, he should have added 8 to both sides rather than subtracting 8 from both sides.
No, he should have multiplied both sides by 16 rather than dividing both sides by 16.

A motorist takes 4. 5 hours to reach his destination at 80km/ h.
If he wants to complete his journey in 4 hours at what speed must he travel
Answer:
71.11 km/h
Step-by-step explanation:
D = S/T
D = distance
S = Speed
T = Time
The motorist is going 80km/h and takes 4.5 hours to reach his destination.
80/4.5 = 17.77km
The motorist travels 17.77km
Now find how fast he'll have to go to reach 17.77km in 4 hours.
17.77 * 4 = [71.11 km/h]
Flag In a fish tank 2/3 of the fish are red, 1/4 are yellow, and
the rest are green. There are 42 more red fish than green fish.
What fraction of the total number of fish does 42 represent? (Hint:
42
The fraction that represents the quantity of 42 in relation to the total number of fish is 504/5.
In the fish tank, 2/3 of the fish are red, 1/4 are yellow, and the remaining fish are green. Additionally, there are 42 more red fish than green fish. We need to determine the fraction that represents the quantity of 42 in relation to the total number of fish.
Let's assume the total number of fish in the tank is represented by the variable "T."
From the given information, we can deduce the following:
The fraction of red fish is 2/3 of the total number of fish: (2/3) * T.
The fraction of yellow fish is 1/4 of the total number of fish: (1/4) * T.
The fraction of green fish is the remainder after considering the red and yellow fish: (1 - (2/3) - (1/4)) * T.
We are also told that the number of red fish is 42 more than the number of green fish:
(2/3) * T = (1/4) * T + 42.
To find the fraction that represents the quantity of 42 in relation to the total number of fish, we need to express 42 as a fraction of T.
To do this, we can set up the equation:
42/T = 42/(T * 1) = 42/[(2/3) * T - (1/4) * T].
Simplifying this equation yields:
42/T = 42/[(8/12) - (3/12)].
42/T = 42/(5/12).
To divide by a fraction, we can multiply by its reciprocal:
42/T = 42 * (12/5) = 504/5.
Therefore, the fraction that represents the quantity of 42 in relation to the total number of fish is 504/5.

Total surface area of the tent that is in a shape like a triangular prism
= 255ft²
Step-by-step explanation:
Find the surface area of the triangles.
height = 5ft, base = 5ft
2 Triangles = 5 × 5 ÷ 2 × 2 = 25ft²
Now for the base.
height = 10ft, base = 5ft
base of triangular prism = 10ft × 5ft = 50ft²
And then, the last 2 rectangles.
height = 10ft, base = 9ft
2 Rectangles = 10ft × 9ft × 2 = 180ft²
Lastly, we add all these up.
25ft² + 50ft² + 180ft²
