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\}

Newton's Law of Cooling

Tf=Ts+(Ti-Ts)e^(-kt)   where Tf is temp at time t, Ts is temp of surroundings, Ti is temp of object/fluid.  So we need to find k first.

200=68+(210-68)e^(-10k)

132=142e^(-10k)

132/142=e^(-10k)

ln(132/142)=-10k

k=-ln(132/142)/10

k≈0.0073  so 

T(t)=68+142e^(-0.0073t)  so how long until it reaches 180°?

180=68+142e^(-0.0073t)

112=142e^(-0.0073t)

112/142=e^(-0.0073t)

ln(112/142)=-0.0073t

t= -ln(112/142)/(0.0073)

t≈32.51 minutes

Answer all please, thank you :)

The angles in a triangle add up to 180 degrees.  That's the same sum as a linear pair, which we get when two lines cross.

1. 180 - 65 - 45 = 70

Answer: 70°

2. 180 - 90 - 35 = 55

Answer: 55°

3. 180 - 120 = 180 - 50 - x

x = 70

Answer: 70°

It depends if the 12 spice jars are all different.

If they are:

_ _ _ _ _ _ _ _ _ (9 spaces)

12*11*10*9*8*7*6*5*4

12 possibilities for first one, 11 for second, etc...
