Answer:
its 7
Step-by-step explanation:
7
Sin 0 = 0
Sin 30 = 1/2
Sin 45 = 1/SR of 2
Sin 60 = SR of 3/2
Sin 90 = 1
Another example you can use is P:trees provide air, Q: 7 is an odd number. Write pq as a sentence. Then construct a truth table for this conditional. Solution: The conditional pq represents " If trees provide air, then 7 is an odd number." Trees provide air is the hypothesis, and 7 is an odd number is the conclusion. Note that the logical meaning of this conditional statement is not the same as its intuitive meaning. In logic, the conditional is defined to be true unless a true hypothesis leads to a false conclusion.
The implication of pq is that: since trees provide air, this makes 7 an odd number. However, intuitively, we know that this is false because the trees and the number 7have nothing to do with one another! Therefore, the logical conditional allows implications to be true even when the hypothesis and the conclusion have no logical connection
Answer:
Therefore the magnitude of the applied force is N.
Step-by-step explanation:
Torque: Torque is the cross product of force and the distance of applied force from the rotational axis.
Where is angle between F and r.
Newton-meter is the S.I unit of torque.
Along the positive y axis, the wrench lies .
The length of wrench is 0.1 m.
[ since the vector lies on y axis]
The direction of applied force is along the vector <0,2,-4>.
Then the angle between and <0,2,-4> = the angle between F and .
We know that,
We know that,
Here = 100 N-m, and
Now
Therefore the magnitude of the force is N.
Use the FOIL method to multiply these terms. Multiply the first, outside, inside, and last terms:
(5x - 4)(2x - 5)
(5x)(2x) + (5x)(-5) + (-4)(2x) + (-4)(-5)
10x² - 25x - 8x + 20
10x² - 33x + 20
The area of the rectangle should be 10x² - 33x + 20.
