Answer:
a) (9/2)
b) (9/4)
Step-by-step explanation:
I = ∫¹₀ (x³ - 5x) dx = -(9/4)
a) ∫¹₀ (10x - 2x³) dx = -2 ∫¹₀ (x³ - 5x) dx
∫¹₀ (x³ - 5x) dx = -(9/4) from the given value for I
-2 ∫¹₀ (x³ - 5x) dx = -2 × (-9/4) = (9/2)
b) ∫¹₀ (5x - x³) dx = -1 ∫¹₀ (x³ - 5x) dx
∫¹₀ (x³ - 5x) dx = -(9/4) from the given value for I
-1 ∫¹₀ (x³ - 5x) dx = -1 × (-9/4) = (9/4)
Hope this Helps!!!
Answer:
Bodmas rules first -7 multiplay by 3 and get -21 the 5 multiply by 2 and get 10 ..then +10 minus 21 and get -11
Answer: A. 2x2 - 3x - 8
Just subtract the functions and combine like terms
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x^2 - 5 -(3x + 3)
(f - g)(x) = 2x^2 - 5 - 3x - 3
(f - g)(x) = 2x^2 - 3x - 8
