Acruise ship is traveling south going approximately 22 mph when it hits the gulf stream flowing east at 4 mph. which expression would find the resultant velocity?
a) sqrt(22^2 + 4^2)
b) sqrt(22^2 - 4^2)
c) 22^2 - 4^2
d) 4(22)

The answer is:

The correct option is

a)

Since a right triangle is formed, we can calculate the resultant force using the Pythagorean Theorem which states that:

Where,

c, is the hypothenuse.

a, is one triangle leg.

b, is the other triangle leg.

So, we are given the information:

So, calculating the resultant force (hypothenuse), we have:

Hence, the expression that would find the result velocity is:

a)

Have a nice day!

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

the cost of the apple depends on the weight

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
