Answer:

-20i^2 + 22i - 6

Step-by-step explanation:

(3 - 5i)(-2 + 4i) = -6 + 10i + 12i - 20i^2 = -20i^2 + 22i - 6

if you want to go further,

-20i^2 + 22i - 6 = -2(10i^2 - 11i + 3)

1,478 people went to the movies on Saturday, and 956 people went to the movies on
wlad13 [49]

The percent decrease in people going to the movies from Saturday to Sunday is 35.3%

Step-by-step explanation:

The percent decrease is given by the formula:

Percent\ decrease = \frac{Decrease}{Old\ Value}*100\\where \\Decrease = Old\ value -New\ value\\

Given

New Value = 956

Old Value = 1478

Decrease = 1478-956

= 522

Percent\ decrease= \frac{522}{1478}*100\\=0.353*100\\=35.3\%

The percent decrease in people going to the movies from Saturday to Sunday is 35.3%

Half a number added to the number gives 240.What is the number?
STALIN [3.7K]

Answer:

Step-by-step explanation:

Let number be "n".

Half a number added to the number = 240

This means

0.5n + n = 240

1.5n = 240

Divide both sides by 1.5

n = 240/1.5 = 160

What is the exact solution to the equation 4^5x=3^(x-2)<br> list the steps to get the answer
scoray [572]

Answer: x = -0.377

Step-by-step explanation:

We have the equation:

4^(5*x) = 3^(x - 2)

Now we can use the fact that:

Ln(A^x) = x*Ln(A)

Then we can apply Ln(.) to both sides of the equation to get:

Ln(4^(5*x)) = Ln(3^(x - 2))

(5*x)*Ln(4) = (x - 2)*Ln(3)

(5*x)*Ln(4) - x*Ln(3) = -2*Ln(3)

x*(5*Ln(4) - Ln(3)) = -2*Ln(3)

x = -2*Ln(3)/(5*Ln(4) - Ln(3)) = -0.377
