1st step:  break each of these arrows (vectors) into their x- and y-components.  The pedestrian vector would be <6,0>.

The wind vector would be <-13cos(45), 13sin(45)>  (Notice the x-component is negative because it is to the left.)

2nd step.  Add the two vectors:  <6, 0> + <-9.1924,9.1924>  =  <-3.1924, 9.1924>    This is the resultant vector in rectangular coordinates.   Now you need the magnitude of this vector.

3rd step:  Magnitude is always positive and it is sqrt[x-coord2 + y-coord2]

Magnitude = sqrt(94.6915598949) = 9.7309588374  rounded to whatever

Charra [1.4K]

Answer:

279.62 feet

Step-by-step explanation:

We have a rectangle with 5ft x 305ft sides representing the area between your device and the base of the courthouse.

In addition to this we have an angle of 42 °

The height would come being the length of the opposite side of this triangle.

We know that:

tan (° A) = opposite / adjacent

Adjacent side is 305 ft and ° A is 42 °

Solved for opposite:

Opposite = adjacent * tan (° A)

Opposite = 305 * tan (42) = 274.62 feet

We must add 5 feet to this result and we are left with:

274.62 + 5 = 279.62

It means that the height is 279.62 feet

What is compound interest?​
kakasveta [241]

Answer:

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
