Answer:

The points corresponding to P=(3,4) and Q=(6,7), so the answer is D.

Step-by-step explanation:

Ok, in mathematics, given two sets X and Y, the collection of all the ordered pairs (X, Y), formed with a first element in X and a second element in Y, is called the Cartesian product of X and Y. The Cartesian product of sets allows define relationships and functions. In this case, it is a function that contains two points, denoted P and Q. Given, the ordered pair of each, first read the one corresponding to the X axis and then to the Y axis.

For P: you read X and you see that it is on 3 (between 2 and 4), and then the Y axis is on 4 (between 3 and 5).

For Q: you read X and you see that it is on 6 (between 5 and 7) and then the Y axis is on 7 (between 6 and 8)

1. Rotate segment C D 180° around point D.

Yuliya22 [10]

Rotating CD 180 degrees around the point D would mean rotating it to the other side of D, in other words, rotating it clockwise. The new line would be D->M->C

Rotating CD 180 degrees around the point E would mean rotating it clockwise till "E" is a point of the line. The new line would be E->M->D.

Rotating CD 180 degrees would keep the line in the same position right now but with CD being in different order. The new line would be D->M->C.

Best of Luck!

Find tan2θ if θ terminates in Quadrant IV and cosθ =3/5 .

Liula [17]

Answer:

The answer to your question is $\frac{-8}{3}$

Step-by-step explanation:

Data

cos Ф = 3/5

tan2Ф = ?

Quadrant IV

Process

1.- Remember that tanФ = $\frac{Opposite side}{Adjacent side}$ and cos Ф = $\frac{adjacent side}{hypotenuse}$

then, adjacent side = 3 and hypotenuse = 5

2.- Calculate opposite side

O² = h² - a²

O² = 5² - 3²

O² = 25 - 9

O² = 16

O = 4

3.- Calculate the tan 2Ф

tan 2Ф = 2( $\frac{-4}{3}$ ) The opposite side is negative in the fourth

quadrangle

tan 2Ф = $\frac{-8}{3}$
