Answer:

The greatest number is 32 .

Step-by-step explanation:

As given

The ratio of three numbers is 4 : 3 : 1.

The sum of the numbers is 64.

Let us assume that the x be the scalar multiple of the numbers .

First number = 4x

Second number = 3x

Third number = x

Than the equation becomes

4x + 3x + x =  64

8x = 64

x = \frac{64}{8}

x = 8

Thus

First number = 4x

                     = 4 × 8

                     = 32

Second numbers = 3x

                             = 3 × 8

                             = 24

Third number = x

                       = 8

Therefore the greatest number is 32 .

Total value of ratio = 4+3+1 = 8

value of 1 unit = 64/8 = 8

numbers are 4(8), 3(8), 1(8) = 32, 24, 8

so, the greatest number is 32

Vector V is in standard position and makes an angle of 50° with the positive x-axis. Its magnitude is 18. Write V in component f
Umnica [9.8K]

Answer:

11.57 units east, 13.79 units upwards

11.57i + 13.79j

Step-by-step explanation:

V = 18 units at an angle of 50° to the positive x-axis

In component Form, this is how each component is calculated

a = 18cos50° = 11.57 units east

b = 18sin50° = 13.79 units upwards

check if your answer is correct

\sqrt{11.57^{2} +13.79^{2} } = 18.0

In vector component form ai + bj = 11.57i + 13.79j
