Answer:

4\sqrt{3}/3

Step-by-step explanation:

tan 30 = \sqrt{3} /3

cos 30 = \sqrt{3}/2

sin 60 = \sqrt{3}/2

=> Total = \sqrt{3} /3 + \sqrt{3}/2 x 2 = 4\sqrt{3}/3

Answer:

\sqrt{3} + \frac{5\sqrt{3} }{6}

Step-by-step explanation:

tan(30°) = \frac{\sqrt{3}}{3}

cot(30°) = \sqrt{3}

sin(60°) = \frac{\sqrt{3}}{2}

\frac{\sqrt{3} }{3} +\sqrt{3} +\frac{\sqrt{3}}{2}  = \sqrt{3} +\frac{5\sqrt{3} }{6}

In an effort to learn more about the wild lemur population in Madagascar, a researcher wants to collect a sample. Which statemen
steposvetlana [31]

A reseacher wants to collect a sample to learn more about the wild lemur population in Madagascar. According to this, the true statement is the reseacher can assign each lemur a number and then use a systematic sampling (option A).

Systematic sampling is a form of sampling characterized by choosing the sample at random. According to the above, random sampling is the best option for the researcher.

It is not easy to study the entire population of lemurs in Madagascar, therefore systematic sampling is ideal. In this way, the researcher can sample a few lemurs and using this probability method can draw conclusions.

According to the above, the correct answer is A. because it presents information corresponding to the situation presented.

WILL GIVE 98 POINTS!!!! NOT PLAYING!!!!!!! WILL MARK BRAINLIEST!!!!!!!! + THANKS AND 5 STAR RATING!!!!!!!! JUST ANSWER ALL QUEST
just olya [345]

Answer:The first one is 2.333333333

Step-by-step explanation:Simplifying

5(2 + -1j) + (2j + -3) = 0

(2 * 5 + -1j * 5) + (2j + -3) = 0

(10 + -5j) + (2j + -3) = 0

Reorder the terms:

10 + -5j + (-3 + 2j) = 0

Remove parenthesis around (-3 + 2j)

10 + -5j + -3 + 2j = 0

Reorder the terms:

10 + -3 + -5j + 2j = 0

Combine like terms: 10 + -3 = 7

7 + -5j + 2j = 0

Combine like terms: -5j + 2j = -3j

7 + -3j = 0

Solving

7 + -3j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + -3j = 0 + -7

Combine like terms: 7 + -7 = 0

0 + -3j = 0 + -7

-3j = 0 + -7

Combine like terms: 0 + -7 = -7

-3j = -7

Divide each side by '-3'.

j = 2.333333333

Simplifying

j = 2.333333333

The function,f, shifts the parent function 5 units
omeli [17]

Answer:

To shift right 5 units equation needs to be: y=0.5(x-<u>5</u>)^2

To shift left 5 units equations needs to be y=0.5(x+<u>5</u>)^2

To shift up 5 units equation need to be y=0.5x^2 +<u>5</u>

To shift down 5 units equation need to be y=0.5x^2 -<u>5</u>

For the question with 8 units just replace all the <u>5</u> with 8.

Kobotan [32]

Answer:

Step-by-step explanation:

We can apply Pythagoras' Theorem.

so, 65² = 52² + d²

=> d² = 4225 - 2704

=> d² = 1521

so, d = √1521 = 39 yards
