PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!
Nadya [2.5K]

Answer: B

<u>Step-by-step explanation:</u>

  x³ - 3x²  + 16x - 48 = 0

→ x²(x - 3)   + 16(x - 3) = 0

→ (x² + 16) (x - 3) = 0

→ (x² - (-16)) (x - 3) = 0

→ (x - 4i)(x + 4i)(x - 3) = 0

→ x - 4i = 0    x + 4i = 0   x - 3 = 0

→  x = 4i          x = -4i        x = 3

2 imaginary roots         and 1 real root

Maureen walked 3 miles how many feet did she walk
Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}

\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}

\text{Number of feet Maureen walked}=15,840\text{ feet}

Therefore, Maureen walked 15,840 feet.

mamaluj [8]

Answer:

Step-by-step explanation:

The purple circle, not ring is pi 7 squared = 153.93804

Then subtract the smaller circles area (pi 4 squared) = 153.9... - 103.6725576 =

50.2654824

Purple ring is 50.2654824

The entire circle is 4+3+3 (10) squared times pi = 314.1592654

( 50.2654824 / 314.1592654 ) x 100 = 15.999999998 %
