Como se calcula la medida de la sircunferencia si conocen la medida del diámetro
anygoal [31]
Para encontrar la medida de la circunferencia se aplica la ecuación P = π*D.

Explicación.

El perímetro es la medida total de todos los lados que pueda tener una figura geométrica, además se tiene que tener en cuenta que es una magnitud fundamental de los polígonos.

Para una circunferencia el perímetro se encuentra multiplicando el diámetro y el número π (pi), como se muestra a continuación:

P = π*D

Dónde:

P es el perímetro.

D es el diámetro

Geometry Question with Circles: If GP=PH, GA=17, mED=37, and mAB =87c find each measure.
Romashka [77]

The geometry illustrates that the value of DB is 34°

<h3>How to calculate the angles?</h3>

AB = 87°

ED = 37°

BCD will be:

= (360° - 87° - 32°)/2

= 118°

FA will be:

= 118°/2

= 59°

DC = 118/2 = 59°

HB = GA = 17°

DB = 2 × 17° = 34°

EG = GA = 17°

Consider the polynomials p1(t) = 1 + t , p2(t) = 1 -t , and p3(t) = 2 (for all t). By inspection, write a linear dependence rela
emmasim [6.3K]

Answer:

\{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}

Step-by-step explanation:

Given the polynomials:

p_1(t) = 1 + t\\ p_2(t) = 1 -t\\p_3(t) = 2\\

On Inspection

(1+t)+(1-t)=1+1+t-t=2\\$Therefore:\\p_1(t)+p_2(t)=p_3(t)

By the Spanning Theorem  

If one vector in S is a linear combination of the others, we can delete it and get a subset (one vector smaller) S' \subseteq S that has the same span.

Therefore, since p_3(t)=p_1(t)+p_2(t)

Span\{p_1,p_2,p_3\}=Span\{p_1,p_2\}

p_1$ and p_2 are linearly independent because p_1 cannot be written in terms of p_2.

Therefore, \{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}$ as required.
