Mathematics
1 answer:
vodomira [7]3 years ago
6 0

Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

- a(-4-5a) - 3a(2 + a) =
Lorico [155]

Answer:

Let's simplify step-by-step.

(−a)(−4 − 5a) − 3a(2 + a)

Distribute:

= (−a)(−4) + (−a)(−5a) + −3a^2 + −6a

= 4a + 5a^2 + −3a^2 + −6a

Combine Like Terms:

= 4a+5a^2 + −3a^2+ −6a

= (5a2+ −3a^2) + (4a + −6a)

= 2a2 + −2a

Final Answer:

= 2a^2−2a!

For which of the following integrands will the table method for parts produce an antiderivative?
Sonja [21]

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
