What is the distance between the points R (5,7) and S (-2,3) 1: 25 2:33 3:55 or 4:65
Shtirlitz [24]
d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}
d = \sqrt{(-2 - 5)^{2} + (3 - 7)^{2}}
d = \sqrt{(-7)^{2} + (-4)^{2}}
d = \sqrt{49 + 16}
d = \sqrt{65}

The answer is 4, √(65).

Which statement describes the daily motion of the moon?
vladimir1956 [14]

hi again uwu

Answer:  i know that the moon rises in the east, and takes 27 1/3 days to go around the earth....

Step-by-step explanation:

because every time Earth spins around once the moon moves about 13 degrees east along its orbit.Thus, the Earth must rotate an extra 13 degrees more each day for a point on its surface to be roughly under the moon again. since earth takes about 50 minutes to spin 13 degrees the moon rises about 50 minutes later each day and sets about 50 minutes later too.

What’s the y- intercept and x-intercept of y = 3/4x + 3
DochEvi [55]

Answer:

see below

Step-by-step explanation:

y = 3/4x + 3

To find the y intercept, let x =0 and solve for y

y = 0+3

The y intercept is 3

To find the x intercept, let y =0 and solve for y

0 = 3/4x+3

-3 = 3/4x

-3 *4/3 = 3/4x*4/3

-4 =x

The x intercept is -4
