al dividir A entre 23 se obtuvo 247 de cociente y el residuo fue el maximo. hallar A a)5242 b)5436 c)5703 d)5332 solo esas 4 alt

yuradex [85]

Aplicando la división, hay que el valor de A es dado por:

c) 5703

Una división es representada por:

$\frac{a}{b} = c + \frac{r}{b}$

En que:

c es el cociente.

r es el residuo.

En este problema, $b = 23$ , y también:

Cociente de 247, o sea, $c = 247$ .

Residuo maximo, que es 22, o sea, $r = 22$ .

$\frac{a}{b} = c + \frac{r}{b}$

$\frac{A}{23} = 247 + \frac{22}{23}$

$A = 23(247) + 22 = 5703$

El valor de A es dado por:

c) 5703

What is the prime factorization of 45÷2

KATRIN_1 [288]

I think the question is supposed to be 45/3 which will give 15.The prime factorization of 15 is simply splitting 15 into product of prime factors, which is 3*5.
Please mark me as brainliest.

Find an equation equivalent to r= 1 + 2 sin thete in rectangular coordinates

noname [10]

Answer:

x^2+y^2=(x^2+y^2-2y)^2

Step-by-step explanation:

Here we are given that

r=1+2sin

we know that the polar cordinates are represented as

x=rsin

y=rcos

Also squaring both and adding them gives you ,

Hence

also r=1+2sin

1+2sin =

Also ,

r = r=1+2sin

also sin =

Hence replacing sin we get

STEP

Equation at the end of step 1

3 ${}^{2}$ x ${}^{2}$ - 1

STEP

Trying to factor as a Difference of Squares:

2.1 Factoring: 9x ${}^{2}$ -1

Theory : A difference of two perfect squares, A ${}^{2}$ - B ${}^{2}$ can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A ${}^{2}$ - AB + BA - B2 =

A ${}^{2}$ - AB + AB - B2 =

A ${}^{2}$ - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 9 is the square of 3

Check : 1 is the square of 1

Check : x ${}^{2}$ is the square of x1

Factorization is : (3x + 1) • (3x - 1)

Final result :

(3x + 1) • (3x - 1)
