Step-by-step explanation:
The question is incomplete, as the dimension of the dam is not given.
However, a general way of calculating volume is to calculate the base area and the multiply by height.
Take for instance,the dam has a rectangular base of 20m by 30m.
The base area will be
Area = 20m * 30m = 600m²
If the height of the water in the dam is 40m, then the volume is:
Volume = 600m² * 40m
Volume = 24000m³
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.
Answer:
f(x) = 2x² +13x -7
Step-by-step explanation:
Given a root r, a factor of the expression with that root is (x -r). For your roots, the factors of a suitable polynomial are ...
(x -1/2)(x +7)
Since you don't want any fractions, you can multiply this by 2:
(2x -1)(x +7)
And you can eliminate parentheses and write it as a function.
f(x) = (2x)(x +7) -1(x +7) = 2x² +14x -x -7
f(x) = 2x² +13x -7
