Two ships leave a harbor at the same time. one ship travels on a bearing s 15 degrees w at 10 miles per hour. the other ship travels on a bearing n 75 degrees e at 11 miles per hour. how far apart will the ships be after 2 hours?

The distance between the ships after 2 hours will be 36.38 miles.

Explanation:

Given that,

One ship travels on a bearing S 15 degrees W at 10 miles per hour.

The other ship travels on a bearing N 75 degrees E at 11 miles per hour.

After 2 hour,

One ship covered the distance is 20 miles.

Other ship covered the distance is 22 miles.

We need to calculate the distance between the ships

Using cosine rule

Put the value into the formula

Hence, The distance between the ships after 2 hours will be 36.38 miles.

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
