Answer:

(f-g)(2)=14

Step-by-step explanation:

We are given the two functions:

f(x)=3x^2+1\text{ and } g(x)=1-x

And we want to find the value of:

(f-g)(2)

This is equivalent to:

(f-g)(2)=f(2)-g(2)

Substitute:

=(3(2)^2+1)-(1-(2))

Evaluate:

=(3(4)+1)-(1-2)=(12+1)-(-1)=13+1=14

Therefore:

(f-g)(2)=14

A news agency publishes results of a recent poll. It reports that candidate A leads candidate B by 10% because 45% of the poll p
natali 33 [55]

We need to use the formula to find Margin of Error but through the sample proportion, that is

E=z*\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}

We will use a 95% confidence interval, that is a z value of 1.96 (Search in a Normal distribution table)

A) For A our \hat{p} (proportion) is equal to 0.45. So applying the formula,

E=1.96*\sqrt{\frac{0.45(1-0.45)}{900}}

E=3.25\%

B) We make the same of point A, but change our proportion to 0.35

E=1.96*\sqrt{\frac{0.35(1-0.35)}{900}}

E=3.116\%

c) We need to calculate the SE through proportion for 0.1, that is

SE = \sqrt{(\frac{\hat{p_1}(1-\hat{p_1})}{n})+(\frac{\hat{p_2}(1-\hat{p_2})}{n})}

Then our Error is given by,

E=z*SE

E=1.96*\sqrt(0.45*\frac{0.55}{900}+0.35\frac{0.65}{900}

E=0.045

What is cosA for this triangle?<br><br> 48/55<br><br> 55/73<br><br> 55/48<br><br> 48/73
mash [69]

For this case we must indicate the cosine of A, of the figure shown. By definition:

Cosine (A) = \frac {Cateto\ adjacent\ to\ the \ angle} {hypotenuse}

Substituting the values we have:

Cosine (A) = \frac {48} {73}

So, we have to:

Cosine (A) = \frac {48} {73}

Option D
