Answer:
Step-by-step explanation:
Take out 4 from each term on the left.
4(B^2 - B) = -1 Divide both sides by 4
4(B^2 - B)/4 = - 1/4
(B^2 - B) = -1/4 Add 1/4 to both sides
B^2 - B + 1/4 = - 1/4+1/4
B^2 - B + 1/4 = 0
(b - 1/2)(b - 1/2)
This has 2 equal roots of (b - 1/2)(b - 1/2) or b = 1/2 , b = 1/2.
When that happens, the quadratic just touches the x axis (in this case at 1/2)
I've provided a graph to show you how this happens. None of your choices are what I'm getting. The answer is 1/2 no matter how it is factored.
By the polynomial remainder theorem, the remainder upon dividing
by
will be the value of
.
... | 1 ... -6 ... -4 ... -6 .... -2
3. | .. ... 3 ... -9 ... -39 .. -135
--------------------------------------
... | 1 ... -3 ... -13 . -45 .. -137
So you have
which means
.
Answer: 114
Step-by-step explanation:
680/17 is 40
40+40+17+17 is 114.
Answer:
6 ft
Step-by-step explanation:
As we know that, the arch meet the ground are the value of x when y = 0
y=−0.9(x+3)(x−3)
<=> 0 = −0.9(x+3)(x−3)
<=> x=3 or x=-3
So we have 2 coordinates: (3, 0) and (-3,0) and the distance between them is:
3 -(-3) = 6
=> The width of the arch at ground level is 6 ft
Neither equation is correct. the correct equation would be 44 - 7 = x
