Answer:

The answer to your question is: 24/25

Step-by-step explanation:

Remember that sinФ = opposite leg / hypotenuse

Opposite leg = 24/25

Hypotenuse = 1

then sin Ф = (24/25) / 1

sin Ф = 24/25

Given two vectors A=2i+3j+4k,B=i-2j+3k find the magnitude and direction of sum<br>(physics question)

Law Incorporation [45]

Answer:

$Magnitude =\sqrt{59} \\\\Direction \: of \: \overrightarrow{A + B} = \frac{3}{\sqrt {59}} , \:\frac{1}{\sqrt {59}} , \:\frac{7}{\sqrt {59}}$

Step-by-step explanation:

A=2i+3j+4k

B=i-2j+3k

Sum of the vectors:

A + B = 2i+3j+4k + i-2j+3k = 3i + j + 7k

$Magnitude =\sqrt{3^2 + 1^2+ 7^2} \\\\Magnitude =\sqrt{9+1+49} \\\\Magnitude =\sqrt{59}$

Direction of the sum of the vectors:

$\widehat{A + B} =\frac{\overrightarrow{A + B}}{Magnitude\: of \:\overrightarrow{A + B}} \\\\\widehat{A + B} =\frac{3i + j + 7k}{\sqrt {59}} \\\\\widehat{A + B} =\frac{3}{\sqrt {59}} i +\frac{1}{\sqrt {59}} j+\frac{7}{\sqrt {59}} k\\\\Direction \: of \: \overrightarrow{A + B} = \frac{3}{\sqrt {59}} , \:\frac{1}{\sqrt {59}} , \:\frac{7}{\sqrt {59}} \\\\$

Which expression is equivalent to –5(6x – 3) – 4(–2x + 1) + 3(4x) – 8?

Sedaia [141]

Answer:

C = -10x+3

Step-by-step explanation:

So the simplified version of the main expression is -10x+3. after finding the main expression you just need to simplify the rest of them too.

A. = -10x+9

B. = 8x-9

C. = -10x+3

D. = -10x-3

Now that you simplified all the expressions, you can pick out the one that's the same as the target expression, which is C.

5(1+4K)+7k=4(7k+2)<br> Help

stepladder [879]

Answer:

k = -3

Step-by-step explanation:

1) Simplify

5+20k+7k=28k+8

2) Combine the k's

5+27k=28k+8

3) Subtract 27k on both sides

5=k+8

4) Subtract 8 on both sides

-3=k or k= -3
