-50
So you want to pair them up
(1-2)+(3-4)+(5-6)..+(99-100)
And write the answer for each pair
(-1)+(-1)+(-1)..+(-1)
When looking at this you can see that each pair equals -1
So you divide 100 by 2 and multiply that by the -1
100/2=50
50*-1=-50
Answer is 50
You would use the same method if you were going up to a number like a 500
The answer would be -250

Answer:
Step-by-step explanation:
V = x(14 - 2x)(18 - 2x)
V = (14x - 2x²)(18 - 2x)
V = (252x - 28x² - 36x² + 4x³)
V = 4x³ - 64x² + 252x
V' = 12x² - 128x + 252
0 = 3x² - 32x + 63
x = (32 ±√(32² - 4(3)(63))) / (2(3)
x = (32 ± √268) / 6
x = 8.06 inches, which we ignore as this would mean we have no material left at all in the 14 inch dimension.
or
x = 2.60488... 2.60 inches
Vmax = 0.60(14 - 2(2.60))(18 - 2(2.60)) = 292.86478... = 292.86 inches³
Answer:
the original amount is $1,642
Step-by-step explanation:
The computation of the original amount is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
So,
Present value = Future value ÷ (1 + rate of interest)^number of years
= $3,024.56 ÷ (1 + 0.26 ÷ 2)^5
= $1,642
Hence, the original amount is $1,642
