A patio is in the shape of a trapezoid. The length of the longer base is 17 feet. The length of the shorter base is two feet les

erma4kov [3.2K]

Answer:

The area of the patio is 43 square feet

Step-by-step explanation:

In this question, we have a trapezoid and we are asked to calculate the area of the patio which is in the form of the trapezoid.

Please check attachment for possible trapezoid picture.

Mathematically, the area of the trapezoid can be calculated using the mathematical formula below;

A = 1/2 (a+b) h

where a and b are the lengths of the parallel sides.

Now, let’s say a is 17 feet

b was stated explicitly to be 2 feet half the length of the longer base. That would be 1/2(17) - 2 = 8.5 -2 = 6.5 feet

Now let’s calculate the area of the patio;

A = 1/2(6.5+17) * 4 = 2(23.5) = 47 square feet

If x=(10-3i) and y=(3-10i), then xy=? and x/y=?

Solnce55 [7]

Answer:

$xy=-109i$

$\frac{x}{y}=\frac{60}{109}+\frac{91}{109}i$

Step-by-step explanation:

$xy=(10-3i)(3-10i)$

To compute x times y must use foil on the right hand side.

First: $10(3)=30$

Outer: $10(-10i)=-100i$

Inner: $-3i(3)=-9i$

Last: $-3i(-10i)=30i^2=-30$

------------------------------------Add like terms:

$-109i$

----------------

$\frac{x}{y}$

$\frac{10-3i}{3-10i}$

Multiply top and bottom by bottom's conjugate:

$\frac{(10-3i)(3+10i)}{(3-10i)(3+10i)}$

Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:

$\frac{30+100i-9i-30i^2}{9-100i^2}$

Replace $i^2$ with -1:

$\frac{30+91i+30}{9+100}$

$\frac{60+91i}{109}$

$\frac{60}{109}+\frac{91}{109}i$
