<h3>Given:</h3>

Polygon 1
Polygon 2

The mathematical name for the given 2 polygons.

<h3>Solution:</h3>

The first polygon has 6 sides with an angle sum of 720°, which means the mathematical name given for this polygon is,

$\large\boxed {Hexagon}$

The second polygon has 7 sides with an angle sum of 900°, which means the mathematical name given for this polygon is,

$\large\boxed {Heptagon}$

Hence, the first polygon is a hexagon and the second polygon is a heptagon.

17. El precio de los terrenos en Lima es proporcional al área e inversamente proporcional a su distancia con respecto al centro

grin007 [14]

Answer:

375000

Step-by-step explanation:

We have that in this case the following proportion would be fulfilled:

Price * Distance / area

Now, we have that for a distance of 45 km and an area of 900 m ^ 2 the price is 250,000, now for a distance of 40 km but with an area of 1,200 m ^ 2, how would the price be, we replace:

250000 * 45/900 = P * 40/1200

12500 * 1200/40 = P

P = 375000

Which means that for these conditions the price is 375000.

Write the trinomial as a square of a binomial x^2+2xy+y^2

vitfil [10]

Answer:

$\large\boxed{x^2+2xy+y^2=(x+y)^2}$

Step-by-step explanation:

$(x+y)^2=(x+y)(x+y)\\\\\text{Use FOIL}\ (a+b)(c+d)=ac+ad+bc+bd\\\\=(x)(x)+(x)(y)+(y)(x)+(y)(y)=x^2+xy+xy+y^2=x^2+2xy+y^2$

How Many Close Confidants Do People Have? In a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to g

yaroslaw [1]

Answer:

0.08065

Step-by-step explanation:

Given that in a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to give the number of people in the last six months with whom you discussed matters that are important to you.

If X is random variable then X has mean 2.2 and s = 1.4

n=2006

Std error of mean = $\frac{1.4}{\sqrt{2006} } \\=0.03126$

For 99% since sample size is large, t and z distn almost coincide.

Hence we can take 2.58 as critical value

Margin of error at 99% = $2.58*0.03126\\=0.08065$
