Answer:

Option C is right.

Step-by-step explanation:

Resultant vector is the sum of two vectors.

i.e. addition of horizontal component and addition of vertical components.

For example, if ai+bj is one vector and ci+dj be another vector,

resultant vector = a+ib+c+id

= (a+c)+i(b+d)

i.e. option c is right

Best explained and correct answer gets brainliest.
Zolol [24]
Your answer would be A because $4800 is your starting number and it increases 2% every year. How much is it in 20 years?

You use the formula ab^x
a is your starting number
b is the percentage
x is always the length of time

Since you are increasing and trying to get its worth larger than what it was before you use a number larger than one hundred percent in this case the number would be 1.02.


Y=4800(1.02)^20
Y=$7132.55

galina1969 [7]

Answer:

Answer:

50.2

Step-by-step explanation:

ut =  \sqrt{ {6}^{2}  +  {5}^{2} }   \\  \sqrt{36 + 25}  \\  \sqrt{61 }  \\ using \: cosine \: rule \\ cos \: u =  \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times  \sqrt{61} }  \\  \\  =  \frac{25 + 61 - 36}{78}  \\  \\  = \frac{50}{78 }  \\  \cos \: u = 0.64 \\ m \:u = 50.2
