The coordinates of ABC are A = (-2, -1) B = (-2, -10) C" = (-14, -1)
How to determine the coordinates of ABC?The coordinates of the triangle A"B"C" are given as
A" = (0.5, -1) B" = (5, -1) C" = (0.5, -7)
The transformation is given as
Rotation of 90° clockwise around the originDilation by 1/2 with a center of dilation at the originWhen these transformations are combined, we have
(x, y) ⇒ (-y/2, x/2)
So, we have
A" = (0.5, -1) B" = (5, -1) C" = (0.5, -7)
This gives
A = (-2, -1) B = (-2, -10) C" = (-14, -1)
Hence, the coordinates are A = (-2, -1) B = (-2, -10) C" = (-14, -1)

the null hypothesis claims that the proportion of community college students who work full-time is 0.45. the alternative hypothesis is that this proportion is greater than 0.45. which sample proportion will have the smallest p-value?
The sample proportion will have the smallest p-value is for Z=3 that can be calculated by taking comparisons between Z=1,2 and 3.
Null hypothesis H0= P=0.45
Alternative hypothesis H1= P>0.45
The null hypothesis assumes that any form of distinction among the selected traits which you see in a fixed of records is because of chance. For example, if the predicted income for the playing recreation are truely same to 0, then any distinction among the common income withinside the records and 0 is because of chance.
H=1000, x1=500, x2=600 and x3=700
P1= x1/h=500/1000=0.5
P2=x2/h=600/1000=0.6
P3=x3/h=700/1000=0.7
Z1=P1-P/(P(1-P)/h)61/2 = 0.5-0.45/(0.45*0.55/1000)^1/2 = 0.32
P-value for Z1=P(Z1>0.32)=0.37748
Z2=P2-P/(P(1-P)/h)61/2 = 0.6-0.45/(0.45*0.55/1000)^1/2 = 0.95
P-value for Z2=P(Z2>0.95)=0.17106
Z3=P3-P/(P(1-P)/h)61/2 = 0.7-0.45/(0.45*0.55/1000)^1/2 = 1.59
P-value for Z3=P(Z3>0.95)=0.055917
Thus, the smallest P-value will be for Z3.

As Venus revolves around the sun, it travels at a speed of approximately 22 miles per second. Convert this speed to miles per minute. At this speed, how many miles will Venus travel in 6 minutes?
Answer: In 6 minutes, Venus will travel 1320 * 6 = 7920 miles.
Step-by-step explanation: To convert the speed from miles per second to miles per minute, we multiply the speed by the number of seconds per minute. There are 60 seconds per minute, so Venus travels 22 * 60 = 1320 miles per minute.
In 6 minutes, Venus will travel 1320 * 6 = 7920 miles.

Answer:
ok i can do it if u want then see my m.s.g
The required solutions to the given triangle ABC below as:
(i) sin (B+C/2) = cos (A/2)
(ii) if angle A= 90°, then the value of tan (B+C/2) is is undefined.
What are Interior Angles?Interior angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles.
Given that A, B, and C are interior angles of a triangle ABC.
To solve the question, we would consider trigonometric ratios of complementary angles.
sin (90° - θ) = cosθ
We know that for ΔABC,
∠A + ∠B + ∠C = 180° (Angle sum property of triangle)
∠B + ∠C = 180° - ∠A
On dividing both sides by 2, we get,
(∠B + ∠C)/2 = (180° - ∠A)/2
(∠B + ∠C)/2 = 90° - ∠A/2
Applying sine angles on both sides:
sin {(∠B + ∠C)/2} = sin (90° - ∠A/2)
Since, sin (90° - θ) = cos θ, we get
sin (∠B + ∠C)/2 = cos A/2
(ii) if angle A= 90°, then find the value of tan (B+C/2)
If cos A/2 = 0 so ∠A = 90°
sin (∠B + ∠C)/2 = cos A/2 = 0
tan (B+C/2) = ∞
Thus, the value of tan (B+C/2) is undefined.

Would you rather receive a 3% raise followed by a 9% raise or a 9% followed by a 3%
It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.
What is the percentage increase?
The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original.
It is generally better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.
This is because the percentage raise you receive is applied to your current salary. If you receive a 3% raise first, your salary will be higher when you receive the 9% raise, so the 9% raise will be applied to a higher base salary. This means that you will receive a larger increase in salary overall if you receive the 9% raise first.
For example, let's say you are currently making $50,000 per year. If you receive a 3% raise followed by a 9% raise, your salary would increase to $51,500 after the first raise and then to $56,365 after the second raise, for a total increase of $6,365.
On the other hand, if you receive a 9% raise followed by a 3% raise, your salary would increase to $54,500 after the first raise and then to $56,365 after the second raise, for a total increase of $5,865.
In this example, you would receive a larger increase in salary overall if you received the 9% raise first. This is because the 9% raise is applied to a lower base salary, resulting in a larger increase in salary overall.
Of course, the actual amount of the raise will depend on your current salary and the percentage of the raise. In general, though, it is usually better to receive a larger percentage raise first, followed by a smaller percentage raise.
Hence, It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

If C is the line segment from (5,4) to, (0,0), find the value of the line integral:
The value of line integral of the line segment from (5,4) to, (0,0) is 90.
Given that C is the line segment from (5,4) to (0,0):-
So, our first task is to calculate the line segment
After calculating the line segment, we will be able to calculate the line integral
We know that the equation of line is -
y - y1 = (y1 - y2)/ (x1 - x2) * (x - x1)
So now,
y - 0 = (4 - 0)/ (5 - 0) * (x - 0)
y = 4/5 x
5x - 4y = 0 -----------> (1)
A line integral is used to calculate the area covered by that line
c1 = ∫₀⁴ 5x dx ------> (2)
c2 = ∫₀⁵ -4y dy -----> (3)
c1 = [ 5 x²/2 ]₀⁴ = 5 * ( 4² - 0)/2 = 40

The temperature at 4pm is 43 degrees. Throughout the night it steadily falls 6 degrees.
What is the rate of change in this situation?
Answer:
The rate of change in this situation is 6 degrees per hour.
Step-by-step explanation:
The rate of change in this situation is -6 degrees per hour. To find this, we need to divide the change in temperature by the amount of time over which the change occurs. In this case, the temperature falls from 43 degrees to 43-6=<<43-6=37>>37 degrees, so the change in temperature is 43-37=<<43-37=6>>6 degrees. Since the temperature falls over the course of one night, the rate of change is 6 degrees / 1 night = -6 degrees per hour.

how many integers must you pick in order to be sure that at least two of them have the same remainder when divided by 11?
We need to start by choosing some 10 integers so that we can ensure that when they are divided by 11, at least two of the integers will give the same remainder.
The following is the explanation:
If you divide a number by 11, the answer will be a fraction. There are 11 remainders which might occur, which are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
If for example we choose one number and divide it by 11, there is a chance that the remainder may be any of the 11 (0 reminders 1). Therefore, if we choose 10 numbers, we will have the opportunity to pick 10 unique remainders, ranging from 0 to 10.
In conclusion, if we select one more integer, that is we pick 10 integers, then at least two of them would have the same remainder since there are only 10 remainders.
Because of this, we need to choose 10 numbers such that we can guarantee that at least two of them will provide the same remainder when they are divided by 11.

What is linear System of Equations and it's solution?An ordered pair that satisfies all equations of the system is the solution of the system. A system of linear equations can have one solution, no solution, or an infinite number of solutions. The systems of equations can be classified according to the number of solutions. If a system has at least one i.e unique solution, it is called consistent. We have, the system of equations is
y = 2x + 4 => 2x - y + 4 = 0 --(1)
2y = x + 2 => x - 2y + 6 = 0 --(2)
Comparing the equation (1) with a₁x + b₁y + c₁=0
and equation(2) with a₂x + b₂y + c₂=0
We get, a₁ = 2 , a₂= 1 , b₁ = -1 , c₁= 4 , b₂= -2 , c₂ = 2
Now, compute the ratio of coefficients of variables .
a₁/a₂ = 2/1 , b₁/b₂ = -1/-2 = 1/2 , c₁/c₂= 4/6 = 2/3
=> a1/a2 ≠ b1/b2 ,

Julie is given the data point (6, 7) as a point on the profit equation that she must create. Her boss mentioned that the last equation that
they used was y = 2x+3. If Julie wants to write the new equation that is parallel to the old equation, what would her new equation look
like?
y=6x+7
y=2x-5
y=2x+7. In order to create an equation that is parallel to the old equation, Julie must make sure that her new equation has the same slope as the old equation. The slope of the old equation is 2, so Julie's new equation should also have a slope of 2. Additionally, she must make sure that the y-intercept of her new equation is the same as the given data point, which is (6, 7). Therefore, the new equation should be in the form y = 2x + b, where b is the y-intercept. Plugging in the values from the given data point, we get y = 2x + 7. This equation is parallel to the old equation and passes through the given data point, so it is the correct answer.
Answer:
The answer to the question is that the new equation that is parallel to the old equation and passes through the point (6, 7) is y = 2x - 5.
Step-by-step explanation:
To create an equation that is parallel to the old equation, you need to use the same slope. This means that your new equation should be y = 2x + b, where b is a constant. Since the point (6, 7) is on the new equation, you can plug those values into the equation to find b.
