Point  k is located at  (7,4)  in the coordinate plane. its image is created by the following rule: k'=ro 270°^(k)what are the coordinates of  k'? a. (4,-7)b. (4, 7)c. (7, -4)d. (-7, 4)

We are given coordinate of K point (7,4).

We need to find the new coordinate of K' point.

Given rule is K' = Ro 270°^(k).

That represents rotation of k 270 degree about the origin.

The rule for rotation of 270 degree about the origin is as following:

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

Now, applying same rule on point (7,4).

(7,4)  > (4,-7).

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
