Answer:
55
Step-by-step explanation:
Add the numbers 5 + 8 and you get 13. Multiply 13 x 2 which is 26. Add 33 + 26 and you get 59. Then, subtract it by 4 and you get 55.
Answer:
The answer to your question is 
Step-by-step explanation:
Data
Foci (-2, 2) (4, 2)
Major axis = 10
Process
1.- Plot the foci to determine if the ellipse is vertical or horizontal. See the picture below.
From the graph we conclude that it is a horizontal ellipse.
2.- Determine the foci axis (distance between the foci)
2c = 6
c = 6/2
c = 3
3.- Determine a
2a = 10
a = 10/2
a = 5
4.- Determine b using the Pythagorean theorem
a² = b² + c²
-Solve for b
b² = a² - c²
b² = 5² - 3²
b² = 25 - 9
b² = 16
b = 4
5.- Find the center (1, 2) From the graph, it is in the middle of the foci
6.- Find the equation of the ellipse
Distance === 3hrs * 15miles / 1hr === 45 miles.

Answer:
The graph of a linear function is a straight line. Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.

Answer:
a You must choose at least 3 marbles
Step-by-step explanation:
If the probability is equally likely that you will choose a red or blue marble (1/2)
Then the marbles will need to be the same size or you will know which the color of the marble by the size.
There needs to be the same number of marbles, or you will be more likely to pick the color with more marbles of that color
If you look, you will pick the color of the marble you want.
The probability is determined by the number of marbles in the bag, not by the number you choose
