Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
= (2x² - 9x) + (3x - 2) = 2x² - 6x - 2.
Therefore (f + g)(3) = 2(3)² - 6(3) - 2 = -2.
(f - g)(x) = f(x) - g(x)
= (2x² - 9x) - (3x - 2) = 2x² - 12x + 2.
Therefore (f - g)(-4) = 2(-4)² - 12(-4) + 2 = 82.
(g o f)(x)
= g(2x² - 9x) = 3(2x² - 9x) - 2 = 6x² - 27x -2.
(f o g)(x)
= f(3x - 2) = 2(3x - 2)² - 9(3x - 2) = 18x² - 51x + 26.
The opposite of a negative number is the positive number, so 1 1/2 would be the answer <span />
Answer:
1750 trees
Step-by-step explanation:
Scale :
1 inch² = 1 mile²
Number of pine trees per square inch = 35
Area of model = 50 inch²
Hence,
Since scale factor is ; 1 inch² = 1 mile²
Area of forest will also be 50 mile²
Approximate number of trees on forest ;
Area * number of trees per square inch
50 * 35
= 1750 pine trees
Answer: yes it does lol
Step-by-step explanation:
Answer:
53 hours and 45 minutes
Step-by-step explanation:
since they open for 10 hours and 45 minutes a day.
10*5=50 hours, 45*5=225 minutes
add the minutes and hours together and it is 53 hours and 45 minutes
