Answer:
-1
Step-by-step explanation:
The formula for D/4 is b'^2-ac (where b' = 4/2=2, a=1, c=5). When we use the special discriminant (D/4) we get D/4 = (2)^2-1*5 = 4-5=-1.
Hope this helps!
Answer:
Firstly, we have to transform CHF to in order to work with the same currency and make the comparisson:
If
Then:
Now we can make the comparisons:
a) In Geneva the watch costs and in Manchester it costs .
According to this:
<h2>In Geneva the watch is cheaper</h2>
b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:
Therefore:
<h2>The watch in Geneva is
cheaper than the same watch in Manchester.</h2>
Answer:
Total profit = $59.10
Step-by-step explanation:
Total profit = Total selling price - total buying price
Total selling price = $75.50 + $83.60 = $159.10
Total buying price = 2 × $50 = $100
Hence total profit earned = $159.10 - $100 = $59.10
Answer: 5
----------------------------------------------------------
On the curve, the highest point has a y coordinate of y = 6
The lowest point on the curve has a y coordinate of y = -4
Subtracting the y values gets us: 6 - (-4) = 6 + 4 = 10
Cut that result in half: 10/2 = 5
The amplitude is 5. This is the vertical distance from the midline (y = 1) to either the highest point or the lowest point.
