Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the ___ , followed by a reflection across the line ___.
Answers
Answer:
y = x linex = 0 lineStep-by-step explanation:
The polygon ABCD showed in the image attached is first reflected across the y = x line, from the second quadrant to the fourth quadrant. This reflection will result like the second image.
Then, it's reflect across the y-axis, which in terms of lines would be x = 0 line. This reflection will be like the last position showed in the first image, it's a common reflection with y-axis as a mirror.

the total points scored in a basketball game can be calculated using the expression 3c - 3 if c = 41, how many points total were scored
Answers
Answer:
its actually 126
Step-by-step explanation:
The total points scored in the basketball game is 120 points.
Explanation:To find the total points scored in a basketball game, we can use the expression 3c - 3. Given that c is equal to 41, we can substitute this value into the expression to calculate the total points.
So, 3c - 3 = 3(41) - 3 = 123 - 3 = 120.
Therefore, a total of 120 points were scored in the basketball game.

A circle and a square have the same area. find the length of the diagonal of the square divided by the radius of the circle.
Answers
Let us say that the square have edge = sqrt(pi), then its area is pi since A = edge^2, and therefore the diagonal is pi*sqrt(2).
Meanwhile the circle of radius 1 has area pi since area of circle is A = pi *radius^2.
Therefore we get that the diagonal of the square divided by the radius is:
diagonal / radius = pi*sqrt(2) / 1 = pi*sqrt(2)

A dealer purchased a car for $29,700 and marked it up 12% what is the sticker price of the car
Answers
Answer: $ 33264
Step-by-step explanation:
Since, the original price of the car = $ 29,700
Marked up price = 12 % greater than the original price of the car
= Original price of the car + 12% of the original price of the car
= 29700 + 12% of 29700
= 29700 + 0.12 × 29700
= 29700 + 3564
= 33264
Hence, the marked price of the car = $ 33264
Which does not describe the same situation?
Answers
Answer:
4. Option 3rd.
Step-by-step explanation:
In this question, three options are given.
We need to describe the same situation.
First option: y = 3 + 6x
this equation represent the equation of a line. In that line all the points are related with each other with same relation.
So, this equation describe the same situation.
Second equation:
y is two more than six times x.
We write this situation in equation form.
y = 6x + 2
this is also describe the same situation.
Third option:
this table shows the x-y relation table.
Here no two points are describe the same situation.
So, option 3rd doesn't describe same situation.

bill is on the school archery team. the target has a center bull's-eye and two rings around the bull's-eye. the table gives the probabilities of each outcome. what is the probability that bill will get the next arrow in the inner or outer ring?express your answer as a decimal
Answers
add the 2 probabilities together:
0.297 + 0.423 = 0.72
Answer is C
To determine the probability that Bill will hit the inner or outer ring, you would subtract the probability of hitting the bull's-eye from 1, assuming there are no other sections on the target. If the probability of hitting the bull's-eye is 0.70, the combined probability for the inner or outer ring would be 0.30.
Explanation:The question asks about the probability that Bill will hit either the inner or outer ring on an archery target, knowing that he hits the bull's-eye with certain probabilities. To find this probability, we need additional information that specifies the probabilities of hitting the inner and outer rings. Assuming we know the probabilities of all possible outcomes (inner ring, outer ring, and bull's-eye), we would add together the probabilities of hitting the inner and outer rings to get the total probability of hitting one of those two sections.
If hitting the bull's-eye has a probability of 0.70 (70%), and since the sum of all possible probabilities must equal 1 (100%), the combined probability of hitting either the inner or outer ring would be 1 - 0.70 = 0.30 or 30%. This assumes there are no other sections to hit on the target. The probability in decimal form would be 0.30.

Question 2 : which characteristic distinguishes ieee 1394 from usb 2.0

A shop makes $37.50 for selling 15 calendars. If the shop wants to make $2450, how many calendars does it need to sell?
Answers
37.50/15=$2.5 per calendar
Next find the amount of calendars by dividing the amount the shop wants to sell by the price per calendar.
2450/2.5=980 calendars
The shop needs to sell 980 calendars to make $2450.
To find out how many calendars the shop needs to sell to make $2450, we first determine the price per calendar by dividing the total amount made from selling a batch of calendars by the number of calendars in that batch. The shop makes $37.50 from selling 15 calendars, so each calendar is sold for $37.50 / 15 = $2.50. To reach the goal of $2450, we need to calculate the number of calendars by dividing the target amount by the price per calendar.
$2450 / $2.50 = 980 calendars

If EF=2x-5, FG=3x-6, and EG=19 find the values of x, EF, and FG. The drawing is not to scale.

c. x = 1, EF = -3, FG = -3
d. x = 6, EF = 7, FG = 12
Answers
This means that EF + FG = EG
EF=2x-5
FG=3x-6
EG=19
Now all you do is plug in the numbers.
(2x - 5) + (3x - 6) = 19
5x - 11 = 19
5x = 30
x = 6
Now plug that x into EF and FG.
EF = 2x - 5
EF = 2(6) - 5
EF = 12 - 5
EF = 7
FG = 3x - 6
FG = 3(6) - 6
FG = 18 - 6
FG = 12
So your answers are:
x = 6
EF = 7
FG = 12
d. x = 6, EF = 7, FG = 12

4
Answers
Answer:
The answer is 3.
Step-by-step explanation:
In order to determine the slope of the function, we have to know about linear function.
In any linear function, we can get its slope using two pairs of coordinates that belong to the linear function.
m=Slope of the linear function.
P1=(x1,y1)=First pair of coordinate.
P2=(x2,y2)=Second pair of coordinate.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this case, we have many pairs of coordinates, so we choose two of them:
[tex]P_1=(-1,1)\\P_2=(0,4)[/tex]
Then, we replace them in the slope formula:
[tex]m=\frac{4-1}{0-(-1)}=\frac{3}{1}=3[/tex]
Finally, the slope of the function is 3.
