Answer:
Q(x) is = to 11x² that's my answer
The force being exerted by the cord is m(a+g) if the bucket is being accelerated upward.
If T = 70 N, then <span>a=70N/5.2kg−9.8m/<span>s2</span>=3.66m/<span>s2</span></span>is the maximum acceleration that it could have.
Starting from rest, <span>Δy = 1/2a<span>t2</span>→ t = </span>√2Δy/a = <span>√</span>2∗12.5/3.66 = 2.61s
2^7 b - 2^10
= 2^7( b - 2^3)
Answer:
4a(5a + 1)
Step-by-step explanation:
Given
20a² + 4a ← factor out 4a from each term
= 4a(5a + 1)

Answer:
- f(x) = x
- g(x) = -2x+1
- f(x) -(-g(x)) = -x+1
- f(x) +g(x) = -x+1
- f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not
Step-by-step explanation:
We can define a couple of linear functions as ...
f(x) = x
g(x) = -2x+1
Then the reflected function -g(x) is ...
-g(x) = -(-2x +1) = 2x -1
And the difference from f(x) is ...
f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))
We want to compare that to the sum of the functions:
f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)
The two versions of the function expression have the same value.
These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.
