What divides a design so that every point on one side of the line coincides with a point on the other side of it

Answers

Answer:

line of symmetry

Step-by-step explanation:

Final answer:

The term that represents a design divided so that every point on one side coincides with a point on the other side is known as symmetry. This involves an axis of symmetry dividing the design into two contrasting fields.

Explanation:

The concept in question is commonly known as symmetry, and it is often a key factor in design and visual arts. In a symmetrical design, every point on one side of the line, often referred to as the axis of symmetry, coincides with a corresponding point on the other side. This alignment creates a mirroring effect, dividing the entire design into two contrasting fields, like images divided on a poster. For instance, if you have a vertical line dividing a rectangle directly down the middle, and you have a circle on the left side of the line, a symmetrical design would have a corresponding circle on the right side.

Sam y have ages that are consecutive odd integers. The product of their ages is 783. Which equation could be used to find Jeremy's age, j, if he is the younger man?

Answers

sam and jeremy
consecitive odd
means they are 2 years apart
j is younger
j+2=s
product is 783
783=js
s=j+2
783=j(j+2)
783=j^2+2j
minus783 both sides
0=j^2+2j-783
factor or use quadratic formula
0=(j-27)(j+29)
set to zero

0=j-27
add 27
27=j

0=j+29
minus 29
-29=j
false, cannot be negative age

answer is jeremy is 27 years old

What is the exact value of sec(-405degress)?? ...?

Answers

sec= 1/(cos), you can add or subtract 360 degrees from any angle measurement without changing the value of any of the trig functions i.e. 405 degrees= 405-360=45. cos of 45 is sqrt(2)/2 so sec405= 2/sqrroot2

Suppose that you roll a pair of honest dice. If you roll a total of​ 6, you win​ $18; if you roll a total of​ 11, you win​ $72; if you roll any other​ total, you lose​ $9. Let X denote the payoff in a single play of this game. Find the expected value of a play of this game. Round your answer to the nearest penny.A.) -​ $0.50B.) −​ $1.00C.) ​$0D.) ​$0.75E.) −​ $0.75

Answers

You can roll a total of 6 by rolling (1, 5), (2, 4), (3, 3), (4, 2), or (5, 1). There are 36 total possible rolls that can be obtained, so you roll a total of 6 with probability 5/36.

You can roll a total of 11 by rolling (5, 6) or (6, 5), hence with probability 2/36 = 1/18.

Any of the other remaining 29 outcomes occurs with probability 29/36.

The expected value of your winnings is

$18*5/36 + $72*1/18 - $9*29/36 = -$0.75

so the answer is E.

Need help please....

Answers

To solve this or to simplify it simply divide both the top and bottom terms. In the quotient.

By dividing each term with the correct similar variable, you can simplify the expression.

2x - 3y would be the final answer.
