Answer:

The domain is (all possible values of x) \{0,1,2,3,4,5\}

The range is (all possible values of f(x)) \{250,200,150,100,50,0\}

Step-by-step explanation:

A contestant on a game show is given $250.  He is asked five questions and loses $50 for every wrong answer.

  • If he answer all 5 questions correct, then he will still have $250;
  • If he answers 4 questions correct and 1 question incorrect, he will have $200;
  • If he answers 3 questions correct and 2 questions incorrect, he will have $150;
  • If he answers 2 questions correct and 3 questions incorrect, he will have $100;
  • If he answers 1 question correct and 4 questions incorrect, he will have $50;
  • If he answers 5 questions incorrect, he will have $0.

Let x be the number of wrong answers. Then you get a relationship

\begin{array}{cc}x&f(x)\\ 0&250\\1&200\\2&150\\3&100\\4&50\\5&0\end{array}

The domain is (all possible values of x) \{0,1,2,3,4,5\}

The range is (all possible values of f(x)) \{250,200,150,100,50,0\}

an aircraft carrier leads port heading due west at 28 knots. A helicopter is 175 nautical miles from the carrier at an angle of
emmainna [20.7K]
Let’s say it takes time t hours for the interception.
In that time the carrier travels 28t nm west and the helicopter 130t nm.
Now we use the sine rule to find the angle x which lies between the distance 175 and 130t.
sin(x)/28t=sin35/130t. So sin(x)=28sin35/130=14sin35/65=0.1235 and x=7.0964 degrees.
Therefore the helicopter should use a bearing of 35+7.0964=42.0964 degrees north of east or 47.9 degrees east of north approx.

Which exponential equation is equivalent to the logarithmic equation below? c = ln 2
Sophie [7]
\text{A logarithmic lemma: } \\ \text{It follows that: } \log_a a = 1
\text{Following this property, we can see that: } a^{\log_{a} a} = a
\text{Furthermore, we can create more general properties: } a^{\log_a b} = b

c = \log_e 2 \Rightarrow e^{c} = e^{\log_e 2} \\ \text{Using our third property, we see that: } e^{c} = 2
\text{And finally, this works for any } \log_{a} b \left\{a > 0, b \in \mathbb{R}\right\}
