Find the first three nonzero terms in the power series expansion for the product f(x)g(x).

WARRIOR [948]

Answer:

∑(-1)^k/(2k+1)! (5x)^2k+1

From k = 1 to 3.

= -196.5

Step-by-step explanation:

Given

∑(-1)^k/(2k+1)! (5x)^2k+1

From k = 0 to infinity

The expression that includes all terms up to order 3 is:

∑(-1)^k/(2k+1)! (5x)^2k+1

From k = 0 to 3.

= 0 + (-1/2 × 5³) + (1/6 × 10^5) + (-1/5040 × 15^5)

= -125/2 + 100000/6 - 759375/5040

= -62.5 + 16.67 - 150.67

= - 196.5

A bicycle that usually sells for $230 is on sale for 15% off. Find the sale price.

nikitadnepr [17]

$\frac{15}{100} = \frac{x}{230 } \\ x = \frac{15 \times 230}{100} = \frac{3450}{100 } = 34.5$
15% of $230 is $34.5
$230 - 34.5 = 195.5$
so the price is $195.5
hope this helps
