Answer:

D. 64 (cos(pi)+isin(pi))

Step-by-step explanation:

Put 2+2i into trigonometric form, raise the r value to the power of 4, and multiply the angle value (theta) by 4 to get the equation of z^4. In this case, r was 2(sqrt2), which raised to the 4th power was 64. The angle value was pi/4, which multiplied by 4 was pi. That's how we get the answer:

64 (cos(pi)+isin(pi)). How this helps!

Answer:

assume z is equal to 5.

log(z^4/5) equals log(5^4/5) equals log(5^3) equals 2.096910013.

4 * log(5) - log(5) equals 2.096910013.

they give you the same answer.

this means they're equivalent.

What is the domain of g?

Mrac [35]

Answer:

Solution. The domain of g(x) consists of all real numbers except x = 32, since that input value would cause us to divide by 0. Likewise, the domain of f consists of all real numbers except 1. So we need to exclude from the domain of g(x) that value of x for which g(x) = 1.

A train company charges a flat fee of $175, plus $2.50 per mile for a bus. If the band paid exactly $1,875 for three buses, how

Art [367]

Answer:

680 miles

Step-by-step explanation:

1,875=2.5x+175

Minus 175 each side.

1,700=2.5x

Divide both sides by 2.5

680=x

If the band travels 680 miles for $2.50 each mile, plus the flat fee of 175. The total will be 1,875.

Evaluate the expression for f = -6 and g = -1. fg - f =

Arlecino [84]

Answer:

Step-by-step explanation:

Given the information from the question:

$fg - f = f \times g - f$

Next we can use the order of operations to find the value of the expression.

$fg - f = - 6 \times - 1 - ( - 1) \\ = 6 - ( - 1) \\ = 6 + 1 \\ = 7$
