Write expression as a complex number in standard form and show work [(13i)/(1-2i)]

Answers

Answer 1
Answer: the solution
let A = 13i /1-2i 
    so A = 
13i (1+2i) /(1-2i) ( 1+2i) = 13i (1+2i) /1² - (2i)² = 13i -26 / 1  
finally A = 13i -26

The quotient of x^2+x-6/x^2-6x+5*x^2+2x-3/x^2-7x+10 has ___ in the numerator and ______ in the denominator.

Answers

Answer:

So the quotient of (x^(2) + x - 6)/(x^(2) -6x + 5) X (x^(2) + 2x - 3)/(x^(2) -7x + 10) has (x + 3)² in the numerator and (x + 5)² in the denominator.

Step-by-step explanation:

(x^(2) + x - 6)/(x^(2) -6x + 5) X (x^(2) + 2x - 3)/(x^(2) -7x + 10)

Factorizing the expressions we have

(x^(2) + 3x -2x - 6)/(x^(2) -x - 5x + 5) X (x^(2) + 3x - x - 3)/(x^(2) -2x -5x + 10)

(x(x + 3)- 2(x + 3))/(x(x -1) - 5(x - 1)) X (x(x + 3) - 1(x + 3))/(x(x - 2) - 5(x - 2))

((x + 3)(x - 2))/((x - 5)(x - 1))X((x + 3)(x - 1))/((x - 2)(x - 5))

Cancelling out the like factors, (x -1) and (x - 2), we have

((x + 3)(x + 3))/((x - 5)(x - 5))

= ((x + 3)^(2) )/((x + 5)^(2) )

So the quotient of (x^(2) + x - 6)/(x^(2) -6x + 5) X (x^(2) + 2x - 3)/(x^(2) -7x + 10) has (x + 3)² in the numerator and (x + 5)² in the denominator.

What are the zero(s) of the function f(x) = the quantity of 5 x squared minus 25 x, all over x? x = 5 x = 0 and x = 5

Answers

Answer:

x=5

Step-by-step explanation:

f(x)= (5x^2-25x)/(x)

To find out zeros we replace f(x) with 0

0= (5x^2-25x)/(x)

Now solve for x

first we divide the numerator by x

0=5x-25

Now we facor out GCF 5

0=5(x-5)

Divide by 5 on both sides

0=x-5

Add 5 on both sides

x= 5

zero of the function is x=5

(5x^2-25x)/x
simplify
((x)(5)(x-5))/x=5(x-5)=5x-25=f(x)
(just fyi, that x we cancled is a hole)
set to zero
5x-25=0
5x=25
divide 5
x=5

zeroe is at x=5
or (5,0)


x=5 is answer

PLEASE, PLEASE HELP!!! WILL MARK BRAINLIEST!!! Decompose the following single log statement into several log statements: Log (4x^2) /(3yz)

this reads the log of 4 times x squared, divided by (3 times y times z) the log statement applies to everything to the right.

Answers

Rewrite the original equation as:

Log(4x^2) - log(3yz)

Rewrite log(4x^2) as log(4) + log(x^2)

Rewrite log(4) as 2log(2)

Rewrite log(x^2) as 2log(x)

Separate log(3yz) into 3 logs: log(3), log(y) and log(z)

Now combine them to get:

2log(2) + 2log(x) - log(3) - log(y) - log(z)

Final answer:

The decomposition of the logarithmic expression Log((4x^2)/(3yz)) leads to the end result: Log(4) + Log(x^2) - Log(3) - Log(y) - Log(z). The given expression is separated into individual logarithms applying the logarithmic rules.

Explanation:

The decomposition of the logarithmic expression Log((4x2)/(3yz)) according to the laws of logarithms can be done as follows:

Using the rule that log(a/b) = log(a) - log(b), we can first split the expression into two parts: Log(4x2) - Log(3yz).

From there, we can apply the rule that log(ab) = log(a) + log(b) to split these further. So, Log(4x2) becomes Log(4) + Log(x2), and Log(3yz) becomes Log(3) + Log(y) + Log(z).

Finally, we substitute these back into the original expression to get the final decomposition: Log(4) + Log(x2) - Log(3) - Log(y) - Log(z).
