The number of ways there are to get to the point (7,4) if you have to pass through the point (2,2) is; 1266 ways
<h3>How to find the lattice Paths?</h3>
The formula to get the number of ways to get to the lattice point (x, y) (supposing x, y ≥ 0) by taking steps of one unit each either in the eastward or northward direction is exactly;
(x + y)
= (x + y)!/(x!y!)
( x )
Thus, number of ways from (0, 0) to (2, 2) = (2 + 2)!/(2!2!) = 6 ways
Number of ways to get to point (7,4) from (2, 2) is;
((7 - 2) + (4 - 2))!/(2!2!) = 7!/(2!2!) = 1260
Thus, total number of ways = 1266 ways

Answer:
Step-by-step explanation:
Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}
Answer: 1.4688 x 10^6
Step-by-step explanation: Number has to be in between 1 and 10. Moved the decimal 6 places so that is your exponent
