Given p: 10 < 7, clearly p is false and ~p is true. Also, given q: 10 < 5, clearly q is false and ~q is true.
Thus, the truth value of the conditional statement ~p → ~q is <span>T T → T.</span>
the additive inverse of -8 is 8
to find the additive inverse you just have to change the sign of the number
Answer:
Option A is the correct answer.
Explanation:
Any vector can be resolved in to two components. Horizontal component and vertical component.
Consider a vector F which is at angle θ⁰ to the horizontal, we can resolve this vector in to two.
Horizontal component = F cos θ
Vertical component = F sin θ
Here we have Force , F = 50 pounds
Angle with horizontal = 80°
Horizontal component = F cos θ = 50* cos 80 = 8.68 pounds
≅ 9 lb.
Option A is the correct answer.
Answer:
8x²- x -8
Step-by-step explanation:
The question is not well written. I guess what you mean is:
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9, that is
6x^2+3x-9 - (-2x^2+4x-1). This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes
8x²-x -8
The answer is 8x²-x -8.
It is asking for the tangent ratio at B.
In my answer; angle=theta
tan(theta)=opposite/adjacent
tan(theta)= 3/2
