QUICK HELP! Which graph represents the product of a complex number, z, and the negative real number -1/3 ?

Mathematics

Answer:

C.

Step-by-step explanation:

The minus sign (of the multiplier -1/3) changes the direction of z by 180°. The magnitude of the multiplier 1/3 reduces the magnitude of the product to 1/3 that of z. The graph that has these characteristics is graph C.

insens350 [35]

Answer:

<u>1. New York City:</u> The initial charge is $ 2.50 plus $ 0.50 per 1/5 mile when traveling above 12 mph or per 60 seconds in slow traffic or when the vehicle is stopped. There are other surcharges for overnight, rush hour or congestion.

<u>2. Boston:</u> First 1/7 Mile: $2.60  and each 1/7 Mile thereafter: $0.40.

<u>3. Houston:</u> First 1/11 mile  $2.80 , each additional 1/11 mile  $0.20 . Rate per mile after first mile  $2.20 and wait time per minute  $0.40.

Step-by-step explanation:

Normally, there's a standard fare for each city, so for answering the question we picked three well-known cities for comparing the fares.

<u>1. New York City:</u> The initial charge is $ 2.50 plus $ 0.50 per 1/5 mile when traveling above 12 mph or per 60 seconds in slow traffic or when the vehicle is stopped. There are other surcharges for overnight, rush hour or congestion.

<u>2. Boston:</u> First 1/7 Mile: $2.60  and each 1/7 Mile thereafter: $0.40.

<u>3. Houston:</u> First 1/11 mile  $2.80 , each additional 1/11 mile  $0.20 . Rate per mile after first mile  $2.20 and wait time per minute  $0.40.

Help!!!!!!!! i have no clue
siniylev [52]

Answer: Non-proportional

Step-by-step explanation:

The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70

So...you know that it is not proportional

Which has the greater slope B is not the answer ...
olga nikolaevna [1]

B is the answer.

The slope i got for the table is -1 because i divided -2 by 2.

The slope i got for the graph was 0 because 0/7 is 0.

Which quotient is reasonable? Do not perform the division. 7315 ÷ 12 A. 6 R 9 B. 60 R 9 C. 609 D. 6,009
ANTONII [103]

Answer:

C. 609

Step-by-step explanation:

In the question, 4-digits number were given to be divided by a 2-digits number. Without performing the division, it is only reasonable to say that the quotient will be a 3-digits number.

In the given options, the only 3-digits number is 609

Also, you can multiply 609 by 12 to check how reasonable your guess is.

⇒ 609 x 12 = 7308

The difference between 7315 and 7308 is 7.

The remaining number (7) is not up to 12 and when 7 is divided by 12 it will not give a whole number digit.

Therefore, the only reasonable quotient in the given options is 609.
