Determine the domain of the function.f as a function of x is equal to the square root of eleven minus x.

Answer Choices:
All real numbers except 11
x > 11
All real numbers
x ≤ 11

Answers

Answer:

Option D, x ≤ 11

Step-by-step explanation:

We have to determine the domain of the function.

f(x) = $√(11-x)$

This function is defined for the positive values of ( 11 - x ) because under root of negative terms is not defined.

Therefore, domain of the given function will be ( 11 - x ) ≥ 0

x ≤ 11

Option D, x ≤ 11 is the answer.

Alexis has 32 2/5 ounces of beads. How many necklaces can she make if each uses 2 7/10 ounces of beads?

Answers

Answer:

12 necklaces

Step-by-step explanation:

Given,

The total quantity of beads she has = $32(2)/(5)$ ounces,

Also, the quantity of beads needed for each necklace = $2(7)/(10)$ ounces,

Thus, the number of necklaces can be made

$=\frac{\text{total quantity of beads}}{\text{quantity of beads needed for each necklace}}$

$=(32(2)/(5))/(2(7)/(10))$

$=(162/5)/(27/10)$

$=(1620)/(135)$

$=12$

32 2/5 ÷ 2 7/10let's turn above into improper fractions:32 2/5 ----> 162/52 7/10 -----> 27/10so,162/5 ÷ 27/10 -------> 162/5 * 10/27 = 12 necklaces

Right angled triangle calculation. the opposite is 150mm and the only known angle is the right angle how can i calculate the other two sides and angle??

Answers

You can't. One side and one angle is never enough to define a unique triangle.

If the side opposite the right angle is 150mm, the other 2 sides could be . . .

-- 75 and 129.9
-- 100 and 111.8
-- 110 and 101.98
-- 120 and 90
-- 130 and 74.83
-- both 106.07

or any one of an infinite number of other possibilities.

You need to know one more side, or one more angle.

500mm x 600mm how many 25cm fit inside

Answers

Since 1 mm = 0.1 cm, then 500mm x 600mm = 300,000mm, or 30,000cm.

Now you need to divide 30,000 into 25.

30,000 / 25 = 1,200

Now lets check our answer.

1,200 x 25 = 30,000

So 1,200 25's can fit in 500mm x 600mm.
