Mathematics

Statement.
(1). ∠1 is right angle & ∠2 is right angle

(2). ∠1 = ∠2

Reason
(1). Given

(2). Euclid’s Fourth Postulate states that all right angles are equal to one another.

Warning
This is assuming, that we only include Euclidean geometers.
This is because Euclidean geometry only recognise angles between straight lines.

So we have Non-Euclidean geometry for things that are not straight but this raises a question what is a straight line?

A general definition is (A curve is "straight' if tangent vectors stay tangent when parallel-transported along that curve)

Sonja [21]

Answer:

0.2

Step-by-step explanation:

Conditional probability:

P(A | B) = P(A & B) / P(B)

P(striped | red) = P(striped & red) / P(red)

P(striped | red) = 0.05 / 0.25

P(striped | red) = 0.2

x will represent the first unknow number

6x will represent the second number

the two numbers together will equal 21

6x + x = 21  combine like terms

7x =21  divide both sides by 7

x =3


Hope that helps.

HELPPP IF YOU CAN DO THISSSS (BRAINLIST) thank youuu

Answer:

a) $50,880

b) $48

c) 1060

Step-by-step explanation:

a)

-320x^2 + 1920x + 48000 = 0

This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)

x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3

The maximum revenue, y, is the value of the function evaluated at x = 3.

f(x) = -320x^2 + 1920x + 48000

f(-3) = -320(3)^2 + 1920(3) + 48000

f(-3) = 50,880

The maximum revenue is $50,880

b)

Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48

c)

$50,880/$48 = 1060
