Heng tried to define a reflection across line r.

Mathematics
1 answer:
Maurinko [17]3 years ago
5 0

Answer:

Any point N on line r maps to itself.

Step-by-step explanation:

Reflection is one of the examples of solid transformation in which a given point, segment, or figure is flipped over a reference point or line to produce its image. The distance of the object to the reference point or line is the same as the distance of its image to the point or line. And both have the same size, but different orientation.

The option that does not fully define a reflection is; any point N on line r maps to itself, because no image of point N is produced after the operation.

Someone help me pls <br><br>47 as the sum of ______
Elanso [62]

9514 1404 393

Answer:

  (a) 6² +3² +1² +1² = 47

  (b) 5² +4² +2² +1² +1² = 47

  (c) 3³ +4² +2² = 47

Step-by-step explanation:

It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.

The approach where a cube is required can work the same way.

(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1

__

(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...

__

(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2

A school administrator believes that the mean class gpas for a given course are higher than the preferred mean of 2.75 at a sign
Svetach [21]

The mean GPA is greater than 2.75.

<h3>What is GPA?</h3>
  • A grade point average is a figure that represents the average of the final grades obtained in courses over time.
  • A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.

To find the GPA:

  • GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
  • Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
  • Mean GPA = total/50
  • = 2.75.

Therefore, the mean GPA is greater than 2.75.
