Answer:
(1,-2) (3,-2) (4,-4) (1,-4)
Step-by-step explanation:
First of all I noted that the origin would be the centre of rotation.
Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point
Then I drew a line from the point (2,1) to the centre of rotation (the origin)
From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).
I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.
From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.
Then I just drew in the other points to make the rest of the shape.
Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you
The required coordinate of the image of the rotation of the trapezoid (1, -2) (3, -2) (4, -4) (1, -4)
Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.
The graph is a demonstration of curves which gives the relationship between the x and y-axis.
Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).
Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

The correct answer will be given 68 points, explanation also will need to be included
Answer:
74
Step-by-step explanation:
3 3/7 , 4 2/7, 5 1/7, .... 66
=> could be changed into :
24/7, 30/7, 36/7, ...... 462/7
let the numbers = n
462 = 24 + (n-1)(6)
462 = 24 + 6n -6
462 = 6n +18
6n=462-18
6n = 444
n = 444/6 = 74
The equation 4.05p+14.40=4.50(p+3) represents the number p of pounds of peanuts you need to make trail mix. How many pounds of peanuts do you need for the trail mix?
Answer: p=2
Step-by-step explanation:
4.05p+14.40=4.50p+13.50
4.50p-4.50p=13.50-14.40
-0.45p=-0.90
p=-90/-0.45
p=2
.'. 2 pounds are needed to trail milk
Jordan has to solve this division problem: 42 divided by 7 = ?
Which of the following equations can he use?
42 + 7 = ?
7 x 42 = ?
? x 7 = 42
7 divided by 42 = ?
The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:
? x 7 = 42
So, the correct equation is option 3) ? x 7 = 42.
Given that, Jordan has to solve this division problem: 42 divided by 7 = ?
In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.
Therefore, he can use the equation:
? x 7 = 42
This equation represents the inverse operation of division, which is multiplication.
When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).
By solving for the missing factor, he will find the correct answer to the division problem:
The missing factor = 42 / 7 = 6
So, the correct equation is option 3) ? x 7 = 42.

How far was Zane from the edge of the volcano when he started climbing?
Answer:
Hope this helps
accoding to the web "He started out 25 meters below the edge of the volcano. It takes him 6.25 seconds to reach the edge."
Answer:
25 meters below the edge; 6.25 seconds
Step-by-step explanation:
We can represent this with a linear function in slope-intercept form.
We know the rate of change is 4 since he climbs up at 4 meters per second. We do not know the value of b, the y-intercept.
This gives us
y = 4x + b
We know that he is 13 meters below the edge after 3 seconds. Using -13 for y and 3 for x,
-13 = 4(3) + b
-13 = 12 + b
Subtract 12 from each side:
-13-12 = 12+b-12
-25 = b
This gives us the equation
y = 4x - 25
He started out 25 meters below the edge of the volcano.
To find how long it took him to reach the edge, substitute 0 in for y:
0 = 4x - 25
Add 25 to each side:
0+25 = 4x-25+25
25 = 4x
Divide both sides by 4:
25/4 = 4x/4
6.25 = x
It takes him 6.25 seconds to reach the edge.

Answer:
485 × [tex]10^{-10}[/tex]
Step-by-step explanation:
first we need to convert the number to fraction
0.0000000485
[tex]\frac{0.0000000485}{10000000000}[/tex]
it will be
[tex]\frac{485}{10000000000}[/tex]
or can be written as
[tex]\frac{485}{10^{10} }[/tex]
now we need to convert it to scientific notation

When this 3-digit number is rounded to the nearest hundred it rounds down to 600. The digit in the ones place is the third odd number that you count beginning with 1. The sum of the digits is 13. What is the number?
Answer:
1. rounds down to 600 = 601 - 649
2. The digit in the ones place is the third odd number that you count beginning with 1. = 605
3. The sum of the digits is 13
Answer:
625
Step-by-step explanation:
Firstly, I found the ones place because I just needed to know the third odd number starting from 1. The first odd number is 1 then 3 and then 5, so I know that the digit in the ones place is 5.
Ones place: 3rd odd number: 1, 3, 5
Then, I looked at the hundreds place, because I know that it is rounded to down to 600 in the nearest hundred, I know it has to be 649 or smaller and bigger than 600. In the range of 600-649, the hundreds place remains the same, and therefore I know that the digit in the hundreds place is 6
Finally, to determine the tens place, I can do 13-(6+5) I can do this because I know that the sum of the digits is 13. Because 13-11=2, I know that the digit in the tens place is 2
Final number: 625

Given polynomial:
3x⁶ - 2x⁹ + 5x - 12Convert this into standard form, order in descending powers:
-2x⁹ + 3x⁶ + 5x - 12The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.
[tex]\\ \rm\longmapsto 3x^6-2x^9+5x-12[/tex]
Write in standard form

1 [tex]\frac{13}{20}[/tex]
Step-by-step explanation:
1. Convert both [tex]\frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex] into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply [tex]\frac{1}{4}[/tex] by [tex]\frac{5}{5}[/tex] and multiply [tex]\frac{3}{5}[/tex] by [tex]\frac{4}{4}[/tex]
2. You should've gotten, [tex]\frac{5}{20}[/tex] and [tex]\frac{12}{20}[/tex]
3. 6 - 4 = 2, so 2 [tex]\frac{5}{20}[/tex] - [tex]\frac{12}{20}[/tex]
4. You have to convert 1 into [tex]\frac{20}{20}[/tex] and add that to [tex]\frac{5}{20}[/tex]. You should've got [tex]\frac{25}{20}[/tex]
5. Subtract.
