Answer:

270 degrees counterclockwise rotation

Step-by-step explanation:

you can use the formulas, but if you don't know them you can always draw

270 degrees counterclockwise = 90 degrees clockwise

(x,y) -> (y,-x)

A'(1,-2) -> A(-2,-1)

B'(3,-2) -> B(-2,-3)

C'(3,-5) -> C(-5,-3)

D'(1,-5) -> D(-5,-1)

Answer:

270 degrees counterclockwise rotation/ the last answer

Step-by-step explanation:

reflection over the y axis wouldn't work bc the shape would still be a horizontal rectangle

dilation would change the size of the shape

and translation wouldn't map it correctly bc it would still be turned the wrong way

What is the nth term for 7,11,15,19
Murrr4er [49]

Answer:

a_{n} = 4n + 3

Step-by-step explanation:

Note there is a common difference d between consecutive terms, that is

d = 11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4, thus

a_{n} = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Gerry just returned from a cross-country trip. The trip was 3,000 miles from his home, and his total time in the airplane for th
e-lub [12.9K]

The speed of the jet stream is 4.55 miles per hour

Step-by-step explanation:

Distance of one way trip= 3000 miles

The total distance of the round trip= 6000 miles

Total time = 11 hrs

Speed of the plane = 550 miles per hr

Speed = distance/time

= 6000/11

= 545.45 miles per hour

Speed of the plane = 545.45 + speed of the jet stream

550 = 545.45 + speed of jet stream

Speed of jet stream = 4.55 miles per hour

The speed of the jet stream is 4.55 miles per hour
