Given that a trapezoid has the following dimensions, find the area. Area = ________ units^2 (only put the number)

patriot [66]

Trapezoid area = ((sum of the bases) ÷ 2) • height

Trapezoid area = ((5 + 3) / 2) * 5

Trapezoid area = ((8) / 2) *5

Trapezoid area = 20

Which expression is equivalent to this polynomial expression? (2x^5 + 3y^4)(-4x^2 + 9y^4)

SOVA2 [1]

Answer:

A. -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸

Step-by-step explanation:

Given:

(2x⁵ + 3y⁴)(-4x² + 9y⁴)

Required:

Find an equivalent polynomial

Solution:

(2x⁵ + 3y⁴)(-4x² + 9y⁴)

Using distributive property of multiplication

2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)

-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸

There are no like terms to add or combine, therefore:

(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸

Give a power series representation for the function f(x) x^3/(1 + 9x^2)

Nata [24]

Recall that for $|x|$ , we have

$\displaystyle\frac1{1-x}=\sum_{n\ge0}x^n$

Replace $x$ with $-9x^2$ and we get

$\displaystyle\frac1{1-(-9x^2)}=\sum_{n\ge0}(-9x^2)^n=\sum_{n\ge0}(-9)^nx^{2n}$

Lastly, multiply this by $x^3$ , so that

$\boxed{f(x)=\displaystyle\sum_{n\ge0}(-9)^nx^{2n+3}}$
