I’m a computer graphics design program, Mario created a segment with endpoints at ( 1, 5) and ( 7, 3). He then reflected the segment about a vertical line through the segment’s own midpoint. WHAT ARE THE COORDINATES OF THE ENDPOINTS OF THE NEW SEGMENTS?
A. (5, 1) and (3, 7)
B (7, 5) and (1, 3)
C. (7, 3) and (1, 5)
D. (5, 1) and (7, 3)
Answers
Answer:
B (7, 5) and (1, 3)
Step-by-step explanation:
the other answer is right about finding the midpoint :
((x1 + x2)/2, (y1 + y2)/2) = ((1+7)/2, (5+3)/2) =
= (8/2, 8/2) = (4, 4)
now, there is a vertical line through this point, and the original line segment is reflected across this vertical line.
reflections across vertical lines keep the y-values unchanged.
and the x distance of the original point to the midpoint is the same as the x distance of the reflected point to the midpoint.
after all, a reflection means a mirroring.
so, the mirror points are
(..., 5) and (..., 3)
about the x coordinates of distances:
1 to 4 = 3
4 to mirrored point = 3, 4 + 3 = 7.
7 to 4 = 3
4 to mirrored point = 3, 4 - 3 = 1.
so, the points are
(7, 5) and (1, 3)

Find the intervals where the function is increasing and decreasing for the following functions. Using the first derivative test, state which critical value will give you your relative maximum/minimum. You DO NOT have to solve for relative max/min, just the value of c that would give me the min/max based off of the first derivative test.
Answers
f(x) = x^3 - 6x^2 + 12x the function is increasing for x < -2, increasing for x > 4 and decreasing for -2 < x < 4. The critical value that will give you a relative maximum is x = 4. The critical value that will give you a relative minimum is x = -2.
The derivative of the given function is f'(x) = 3x^2 - 12x + 12. Setting this equal to 0 gives us x = 0 and x = 4. By the first derivative test, we can determine that the function is increasing for x < -2, increasing for x > 4 and decreasing for -2 < x < 4. Therefore, the critical value that will give us a relative maximum is x = 4 and the critical value that will give us a relative minimum is x = -2. This can be verified by finding the second derivative of the function, which is f''(x) = 6x -12. Setting this equal to 0 gives us x = 2, which is between the two critical values. Since the second derivative is negative for x < 2, the critical value at x = -2 will give us a relative minimum and since it is positive for x > 2, the critical value at x = 4 will give us a relative maximum.

The point P=(1/2,y)lies on the unit circle shown below. What is the value of y in simplest form?
Answers
The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.
To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.
Plugging in the coordinates of the point P = (1/2, y), we get:
(1/2)^2 + y^2 = 1
1/4 + y^2 = 1
y^2 = 1 - 1/4
y^2 = 3/4.
To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).
Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

Two submarines began dives in the same vertical position to meet at a designated point.
If one submarine was on a course approximated by the equation x + 4y = -14 and
the other was on a course approximated by the equation x + 3y = -8, at what location would they meet?
Answers
Answer:
(10, -6)
Step-by-step explanation:
The solution of the system of the equations given would be the location that they would both meet.
Let's solve:
x + 4y = -14 ----› Eqn. 1
x + 3y = -8 -----› Eqn. 2
Subtract Eqn. 2 from Eqn. 1
y = -6
Substitute y = -6 into Eqn. 1.
x + 4y = -14 ----› Eqn. 1
x + 4(-6) = -14
x - 24 = -14
x = -14 + 24 (addition property of equality)
x = 10.
The answer is: (10, -6)

Explanation:

Use the cosine rule:
c² = a² + b² - 2ab cos(C)
Insert following variables:
6.3² = 9.6² + 8.1² - 2(9.6)(8.1) cos(Q)
39.69 = 157.77 - 155.52 cos(Q)

Refer to the Scheer Industries example in Section 8.2. Use 6.83 days as a planning value for the population standard deviation.
a. Assuming 95% confidence, what sample size would be required to obtain a margin of error of 1 days (round up to the next whole number)?
b. Assuming 90% confidence, what sample size would be required to obtain a margin of error of 2.5 days (round up to the next whole number)?
Answers
Answer:
a)Sample size would be required to obtain a margin of error of 1 days is
n = 179
b) sample size would be required to obtain a margin of error of 2.5 days is n = 20
Step-by-step explanation:
step(i):-
Given Population standard deviation = 6.83 days
a) Given margin of error = 1 day
The margin of error is determined by
\(M.E = \frac{Z_{\alpha } S.D }{\sqrt{n} }\)
Step(ii):-
Given 95 % of confidence level
Now the critical value Z₀.₀₅ = 1.96
\(1 = \frac{1.96 X 6.83 }{\sqrt{n} }\)
√n = 13.38
Squaring on both sides, we get
n = 179.206
b)
step(i):-
a) Given margin of error = 2.5 day
The margin of error is determined by
\(M.E = \frac{Z_{\alpha } S.D }{\sqrt{n} }\)
Step(ii):-
Given 90 % of confidence level
Now the critical value Z₀.₁₀ = 1.645
\(2.5= \frac{1.645 X 6.83 }{\sqrt{n} }\)
Cross multiplication , we get
\(\sqrt{n} = \frac{1.645 X 6.83 }{2.5 }\)
√n = 4.494
Squaring on both sides, we get
n = 20.19
Final answer:-
a)Sample size would be required to obtain a margin of error of 1 days is
n = 179
b) sample size would be required to obtain a margin of error of 2.5 days is n = 20

the factor of 990 is 3, 3, 2, 5, and 11.
Although there are more than two multiples and factors for 990, 330 is not one of them. As a result, only option D is correct (990/11 = 90).

Step-by-step explanation:
You want the density of a piece of driftwood that has a mass of 25 g and a volume of 30 cm³.
DensityUse the given formula with the given numbers, and do the arithmetic.
ρ = m ÷ V
ρ = (25 g)÷(30 cm³) = (25/30) g/cm³ = 0.83 g/cm³
The solution is Option D.
The density of the driftwood is given by the equation D = 0.83 kg/cm³
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the density of the material be represented as D
Now , the equation will be
The mass of the material = m
The value of m = 25 grams
The volume of the material = v
The value of v = 30 cm³
So , density D = m / v
Substituting the values in the equation , we get
Density of driftwood D = 25/30
On simplifying the equation , we get
Density of driftwood = 0.83 kg/cm³

x^2-25 , (x+5) quotient and remainder
Answers
The quotient when (\(x^{2} -25\)) is divided by (x+5) is (x-5) and the remainder is 0.
According to the question,
We have the following information:
(\(x^{2} -25\)) is divided by (x+5)
Now, we can solve this using two ways. First method is to use the long division method and second is to solve the expression using an identity.
We know that the following identity can used to expand the dividend:
\(a^{2} -b^{2} = (a+b)(a-b)\\\)
In this case, we have a = x and b = 5.
\(x^{2} -(5)^{2} = (x-5) (x+5)\)
Now, we have the following expression:
(x+5)(x-5)/(x+5)
(x-5)
Now, the remainder is 0.

Answers
Since the result is negative, we can say that the price of the vase decreased by 37.5%. Rounding to a whole number, the percent change is 38% (since a 37.5% decrease is approximately equal to a 38% decrease).
What is percent?Percent (often symbolized as "%") is a way of expressing a fraction or a portion of something in terms of hundredths. It is used to describe the relationship between a part and a whole, with the whole being represented by 100%. Percentages are commonly used in many areas of life, such as finance, business, and statistics. They can be used to describe changes in values over time, to compare different quantities or amounts, or to express probabilities or frequencies.
Here,
The percent change in the price of the vase can be calculated using the formula:
percent change = (new price - old price) / old price x 100%
In this case, the old price of the vase was $80 and the new price is $50. Substituting these values into the formula, we get:
percent change = ($50 - $80) / $80 x 100%

B' = (Bx + dx, By + dy)
Given that B is located at (5, -4) and B' is located at (20, -16), we can calculate the translation amounts:
