(4 – 2i)(6 + 2i)

Use FOIL

First: 4 multiplied by 6 equals 24

Outer: 4 times 2i gives 8i

Inner: -2i times 6 results in -12i

Last: -2i times 2i equals -4i², which simplifies to 4

Combine the results

24 + 8i - 12i + 4

Final result: 28 - 4i

The answer is: 28 - 4i

Which equation is equivalent to log Subscript x Baseline 36 = 2?

PIT_PIT [12445]

Answer:

x = 6

Step-by-step explanation:

The equation we need to solve is:

$log_{x}36 = 2$

We can change it to exponential form to determine the answer. Below we illustrate the formula to convert log to exponential form:

$log_{x}a=b\\x^b=a$

Next, we convert the log into exponential:

$log_{x}36 = 2\\x^2=36$

Now we will solve for

Find a parametrization, using cos(t) and sin(t), of the following curve: The intersection of the plane y= 5 with the sphere

Svet_ta [12734]

Answer:

The parametrization of the specified curve is $x = 10 cos(t) \ \,z = 10 sin(t)$

Step-by-step explanation:

From the provided problem statement, we derive the function

$x^2 + y^2 + z^2 = 125$

When y = 5

$x^2 + 5^2 +z^2 =125$

$x^2 + z^2 = 100$

$x^2 + z^2 = 10^2$

Converting the above to a polar equation yields

$x = 10 cos(t) \ \,z = 10 sin(t)$

. A manager has just received the expense checks for six of her employees. She randomly distributes the checks to the six employ

tester [12383]

Answer:

13.8%

Step-by-step explanation:

With six employees and six checks, there are a total of 36 (6x6) possible distributions. To determine the probability that exactly five individuals receive the correct checks, there’s only one correct distribution for each of them out of the 36 possibilities, resulting in the calculation of 1/36 for the first and then 1/36 for the subsequent checks. Therefore, the final probability becomes 5/36 = 13.8%.
