You can use pythagorean theorem. 3 miles would be one leg and 2 miles would be the other. (We’ll just call these two a and b in the formula. Letter c, also known as your hypotenuse, will be this ‘straight line distance’.) In order to find this you’ll use: a^2 + b^2 = c^2
Then you’ll find the square root of your sum to get the answer.
Answer: 3^2 + 2^2 = ?
9 + 4 = 13
the square root of thirteen will be about
3.61
18 is the nearest whole number
The graph is a horizontal line at 70 units above the x-axis and parallel to it. f(x) doesn't depend on the value of 'x'. It's always 70.
Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892
Solution: bill would be around $275
Chance of a 2: 1/10. Chance of a 3: 1/10. These are disjoint events (they can’t happen at the same time) but we need the probability that either can happen. So 1/10+1/10=2/10=1/5.
This intuitively makes sense since there are 2 numbers out 10
