Answer:
55
Step-by-step explanation:
Tamara's forearm is given to be 0.366 meters in length, so that a force of 155 newtons is being applied at this distance from her elbow. Again, this force is applied at an angle of 15 degrees, so that the positioning should be the following -
r = ( 0.366( cos 15 ), 0, 0.366( sin 15 ) ),
r = ( 0.35352885242, 0, - 0.0947277705 ) - ( Approximately )
Now the force is applied in the vertical direction, so -
F = ( 0, 0, 155 )
_________________________________________________
We can now multiply the two ( ( 0.35352885242, 0, - 0.0947277705 ) and ( 0, 0, 155 ) ), performing the following calculation to receive " j " the magnitude,
<u><em>And as you can see, j / magnitude is about 54.8</em></u>
- 48r ^2 - 10r + 3
I use the box method for this, however, you can also use the FOIL method for this.
In the box method, draw a square and divide it into four smaller squares. On top of the first row of squares, input the first formula or ( 6r - 1 ) and on the left input the next equation to the side - don't forget whether or not the numbers are negative or not!
After that, multiply like normal - in the first box, multiply the number on top and the number on the left, etc ( If you need clarification, feel free to message me! )
Hope this helps!
Answer:
(5x-8)(x-3)
Step-by-step explanation:
The factor of this equation is 5x-8
So, after the factorization is (5x-8)(x-3)
