Answer:
x³ sin(x)
Step-by-step explanation:
Tabular method is a special form of integration by parts. It works by taking derivatives of u and integrals of dv. You multiply diagonally, then sum the results, alternating the signs.
The important thing to note is that this will produce an antiderivative only if the derivatives of u eventually become 0. So the correct choice is x³ sin(x), because the derivatives of x³ eventually becomes 0:
d/dx (x³) = 3x²
d/dx (3x²) = 6x
d/dx (6x) = 6
d/dx (6) = 0
Answer:
there are no real solutions
Step-by-step explanation:
The discriminant is (-10)² - 4*6*50 is below zero, hence there are no solutions.
Answer:
4/1x plus 2
Step-by-step explanation:
Answer:
1. (1/4 x 5/4 x 5/4) = 25/64
2. (2/4 x 2/4 x 6/4) = 3/8
3. (1/4 x 1/4 x 4/2) 1/8

Answer:
166 m^2
Step-by-step explanation:
Break the diagram into 3 rectangles:
rectangle 1 has 5 m width and 9 m length
rectangle 2 has 19 m width and 4 m length
rectangle 3 has 5 m width and 9 m length
area of rectangle 1 = l * w = 9m * 5m = 45 m^2
area of rectangle 2 = l * w = 4m * 19m = 76 m^2
area of rectangle 3 = l * w = 9m * 5m = 45 m^2
total area = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
= 45m^2 + 76 m^2 + 45 m^2
= 166m^2
