8,9,10,11

Option C is correct.

Image 2:

No of subsets= 16

Step-by-step explanation:

Image 1:

We need to list the elements of the set:

{x | x ∈ Integers and 8 ≤ x < 12}

The values of x are between 8 and 12, where 8 is included because we have less than equal to, but 12 is not included because x is less than 12.

So, elements will be:

8,9,10,11

Option C is correct.

Image 2:

<u>Subsets</u>

If there are n elements in the set, then there are 2ⁿ elements

We have set:

B={car,train,bus,plane}

No of elements in set = 4

No of subsets= 2⁴ = 16

No of subsets= 16

The subsets are:

{{},{car},{train},{bus},{plane},{car,train},{car,bus},{car,plane},{train,bus},{train,plane},{bus,plane},{car,train,bus},{car,train,plane},{car,bus,plane},{train,bus,plane},{car,train,bus,plane}}

Speedy crawled 5/9 yards. Slimy crawled 4 times as far as speedy. How far did slimy crawl?

ELEN [110]

Answer:

2 2/9 yards or 20/9 yards

Step-by-step explanation:

Slimy went 4 times as much as Speedy did so that means 5/9 x 4 yards which is the same thing as 5 x 4/9 so 5 x 4/9 equals 20/9 or 2 2/9 so Slimy crawled 2 2/9 yards.

number 3 says,"If u and v are the measures of complementary angles such that sin u =2/5 and tan v =(square root of 21) 21/2, lab

vodomira [7]

Answer and Explanation:

Using trig ratios, we can express the given values of sin u and tan v as shown below

$\begin{gathered} \sin u=\frac{opposite\text{ of angle u}}{\text{hypotenuse}}=\frac{2}{5} \\ \tan v=\frac{opposite\text{ of angle v}}{\text{hypotenuse}}=\sqrt[]{21} \end{gathered}$

So we can go ahead and label the sides of the triangle as shown below;

We can find the value of u as shown below;
