1. D; -5m+2m, because -5+2=-3

2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.

3. Not 100% sure about this one, but I'll go with B; 4x².

4. C; 5b, that term cannot be combined because the variable is different from the rest.

I hope this was helpful.

One
The five has to be minus, the two is plus. m has to be both. That makes D the answer. The others give 3m 7m and 3m. 
Answer D

Two
This question is VERY important. Don;t leave it alone until you understand it.
2x and x can combine. Nothing else can combine with anything else. The answer you get is

3x - 5y + 3

There are 3 different terms. Nothing else will combine because either the letters are different (x and y) or the 3 has no letter with it. This is your answer. Algebra is real picky about that.

Answer A

Three
Another biggy. x^2 is not the same thing as x. The other three will combine by addition. x^2 must be left alone along with 4.
Answer B 4x^2
If you were actually to do this, you would get 9x + 4x^2
Four
5b. the letters are not the same.

Some government leaders propose allowing oil companies to drill in currently protected lands that may be rich in oil reserves. E
TEA [102]

The type of bias in this survey is question-wording bias because the question is influencing the response (option D).

Question-wording bias occurs when the words selected in the question influence a specific response. Here is one example:

  • Do you believe a cruel practice such as bullfighting should be forbidden?

In this question, the use of the word cruel qualifies bullfighting as negative, and therefore in most cases, people will answer that bullfighting should be forbidden.

This effect occurs in the question for this survey because the section given that an increase in drilling could result in increased tax revenue and additional jobs to the region indirectly states drilling is positive and therefore influences the response of those surveyed.

Note: This question is incomplete because some of the options are missing; here are the complete options:

What type of bias could be most likely affecting the survey results?

A. This is undercoverage bias because some segments of the population will be excluded from the sample.

B. This is response bias because those selected for the survey may not provide truthful opinions about oil drilling.

C. This is voluntary response bias because those most passionate about drilling will be more likely to register an opinion.

D. This is question-wording bias because the information given at the start of the question may lead those surveyed towards a desired response.

What are the critical points for g(θ) = 20θ − 5 tan θ
jarptica [38.1K]

g(θ) = 20θ − 5 tan θ

To find out critical points we take first derivative and set it =0

g(θ) = 20θ − 5 tan θ

g'(θ) = 20 − 5 sec^2(θ)

Now we set derivative =0

20 − 5 sec^2(θ)=0

Subtract 20 from both sides

− 5 sec^2(θ)=0 -20

Divide both sides by 5

sec^2(θ)= 4

Take square root on both sides

sec(θ)= -2  and sec(θ)= +2

sec can be written as 1/cos

so sec(θ)= -2  can be written as cos(θ)= -1/2

Using unit circle the value of θ is \frac{2\pi}{3} and\frac{4\pi}{3}

sec(θ)= 2  can be written as cos(θ)=1/2

Using unit circle the value of θ is \frac{\pi}{3}and\frac{5\pi}{3}

For general solution we add 2npi

So critical points are

\frac{2\pi}{3} + 2n\pi,\frac{4\pi}{3} + 2n\pi , \frac{\pi}{3} + 2n\pi, \frac{5\pi}{3} + 2n\pi
