Can anyone help out with the first question so I can get an idea with the others?
Oksanka [162]
As you can see, the first number line is divided into tenths (0.1, 0.2, 0.3). So, put 8.152 in between 8.1 and 8.2.

Then, the ends of the next number line should be 8.1 at the start, and 8.2 at the end. You keep going smaller to find the exact spot. So, move 5 places inwards and place the 8.153, between 8.15 and 8.16.

Afterwards, the ends of the last number line should be 8.15 and 8.16. Now, it is divided into thousandths. So, find the third spot. Now, it should be 8.153 correctly labeled.

A six-sided number cube is rolled twice.
Gekata [30.6K]

Answer:

1/6

Step-by-step explanation:

There are 6 numbers on a dice

1,2,3,4,5,6

the even numbers are 2,4,6

so there are 3/6 chance of getting an even number

3/6=1/2

5 and 6 are the two numbers greater than 4

so there are 2/6 chance of getting a number greater than 4

2/6=1/3

So for both to happen chance = 1/2 × 1/3

 = 1/6

Fully factored form: f(x) = (x − 3)(x + 3)[x − (2 − i)][x − (2 + i)] The function has ____ real roots and ____ imaginary roots.
Lostsunrise [7]

2 real roots and 2 imaginary roots

f(x) = (x - 3)(x + 3 )(x-2 + i)(x - 2 - i)

(x - 3) and (x + 3) give real roots x = ± 3

(x - 2 + i)(x - 2 - i) give 2 imaginary roots x = 2 ± i
