Answer:
The answer is 4x(exponent of 2)
Step-by-step explanation:
Use the formula for finding axis of symmetry:
-b -25 -25
x = ------ ⇒ --------- = -------- = 2.6
2a 2(-4.9) -9.8
Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
Answer:
Fixed exchange rate
Step-by-step explanation:
We are given,
'A currency whose value is tied to another currency, meaning that the exchange is fixed'.
So, we can see that,
<em>This statement defines the 'Fixed exchange rate' which is a system where the currency is matched (or fixed) to the value of another currency.</em>
Thus, we get,
A 'fixed exchange rate' is a currency whose value is tied to another currency, meaning that the exchange is fixed.
Answer:
x=-3
Step-by-step explanation:
4x-5y=8
Substitute the value -4 in for y
4x -5(-4) = 8
4x +20 = 8
Subtract 20 from each side
4x+20-20 = 8-20
4x = -12
Divide each side by 4
4x/4 = -12/4
x = -3
