Answer:

(y +2)(y +4i)(y -4i)

Step-by-step explanation:

This lends itself to factoring by grouping. Then the quadratic factor can be considered to be the difference of squares and factored accordingly.

(y^3 +2y^2) +(16y +32) = y^2(y +2) +16(y +2) = (y^2 +16)(y +2)

= (y +2)(y^2 -(√-16)^2) = (y +2)(y^2 -(4i)^2)

= (y +2)(y -4i)(y +4i)

A regular six sided die and an eight equal segment spinner, numbered 1 to 8, are rolled/spun simultaneously. What are the odds i

kirill [66]

Answer:

1/3

Step-by-step explanation:

In statistics, the probability of both an event A and an event B happening is equal to the probability of A happening multiplied by the probability of event B happening.

Let's say spinning a prime number is event A and rolling a number ≤ 4 is event B.

There are 8 possibilities on an eight equal segment spinner, and there are 4 prime numbers between 1 and 8 (including 8), which are 2, 3, 5, and 7. This means that the probability of spinning a prime number is 4/8, or 1/2

There are 6 possibilities on a die, and there are 4 possibilities of rolling a 4 or less (1, 2, 3, 4). Therefore, the probability of rolling 4 or less on a die is 4/6, or 2/3

The probability of both of these happening can be calculated by multiplying these together, so 1/2 * 2/3 = 2/6 = 1/3

A JET TRAVELS 460 MILES IN 2 HOURS?

Tanzania [10]

Find how fast it travels in one hour:

460 miles / 2 hours = 230 miles per hour.

A) Multiply the speed per hour by the number of hours:

230 x 8 = 1840 miles in 8 hours.

B) 230 x 20 = 4,600 miles in 20 hours.

C) 460 miles / 2 hours = 230 miles per hour.

Choose all options that apply. Which of the following are equal to 20%? | a) .25 b) 1/5 Oc) 1/10 d) .20

zloy xaker [14]

Answer:

b. and d.

Step-by-step explanation:

$20 = \frac{20}{100} \\ 0.25 = \frac{25}{100} \\ \frac{1}{5} = \frac{20}{100} \\ \frac{1}{10} = \frac{10}{100} \\ 0.20 = \frac{20}{100}$
