Answer:

You do not sail on a "bearing". You sail on a "heading". A bearing is a direction you look at another ship or a lighthouse or whatever. " That tanker bears south by Southwest for example. Math texts drive me nuts. Landlubbers.

Anyway:

first ship east (+x) distance = 10 cos 46 = 6.95 km

first ship north (+y) distance = 10 sin 46 = 7.19 km

180 - 127 = 53 degrees north of west

second ship east distance = -18 cos 53 = - 10.8 km

second ship north distance = 18 sin53 = 14.4 km

difference east-west = 6.95 + 10.8 =

difference north south = 14.4 - 7.9 =

HELP!! Does this graph show a function?
blsea [12.9K]

Answer: B) Yes, the graph passes the vertical line test.

Since such as task is not possible in this case, we consider this curve to be "passing the vertical line test". It means that any x value input leads to exactly one and only one y value output.

One-quarter of the sum of 2 consecutive odd numbers is 14. Find the numbers.​
aalyn [17]

Answer:

27 and 29

Step-by-step explanation:

let A and B the expected numbers

assuming B = A + 2, the problem can be written as follows

¼(A + A + 2) = 14

4*¼(A + A + 2) = 4*14

(A + A + 2) = 56

2A + 2 = 56

A + 1 = 28

A = 27

B = 27 + 2 = 29

A computer technician charges $60 for coming to your house plus $76 per hour for labor. If the total bill for repairs is $269, h
zhuklara [117]

Answer:

2\frac{3}{4} or 2.75, depending on what you need.

Step-by-step explanation:

  1. Subtract $269 by the service fee ($60). This will be $209.
  2. Divide $209 by $76 to calculate hours. This will be 2.75.
  3. (optional) We know that 0.75 is \frac{3}{4}, so let's take 2.75 and convert it into 2\frac{3}{4}. This is your answer.

Is the z score corresponding to a number or score below the mean always negative?
rusak2 [61]

Answer:

Yes

Step-by-step explanation:

The z-score corresponding to a number or score can be calculated using:

z =  \frac{x -  \mu}{ \sigma}

Where x stands for the individual scores, and

\mu

stands for the mean.

Since

x \:  \:  <  \:  \mu

for all numbers or scores below the mean, the difference will always be negative these values below the mean.

This will always result in a negative z-score for all numbers below the mean.
