Answer:
f(x) × g(x)= x^4 - x^3 - 28x^2 + 16x + 192
Step-by-step explanation:
We have the function f(x) = x^2 − x − 12 and g(x) = x^2 − 16 and we need to find the multiplication of both functions.
f(x) × g(x) = ( x^2 − x − 12)(x^2 − 16) = x^4 - 16x^2 -x^3 + 16x -12x^2 + 192
Simplifying:
f(x) × g(x)= x^4 - x^3 - 28x^2 + 16x + 192
What two numbers add up to -1 and multiply to -72?
-9 and 8
Rewrite the expression above
<u>(x - 9)(x + 8)</u>
Answer:
0.38 l
Step-by-step explanation:
Bottles:
- 650 ml
- 0.38 l= 380 ml
- 5020 ml
- 0.045 l= 45 ml
Closest to 1/2 l= 500 ml volume? The difference between the given and 500 ml volume:
- 650 ml- 500 ml= 150 m
- 380 ml- 500 ml= -120 ml
- 5020 ml- 500 ml= 4520 ml
- 45 ml- 500 ml= - 455 ml
The smallest absolute difference in the list above is -120 so the closest one to 1/2 liters is 380 ml= 0.38 l
