Answer:1) 2n - 1
2) 99
see in the picture, u can see that the number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
......
=> The above sequence has: u1 = 1
d = 2
=> u(n) = 1 + 2(n - 1) = 2n - 1
=> the number of shaded squares in the n figure is 2n - 1
b) the number of shaded squares in the 50th figure is 2.50 - 1 = 99
Step-by-step explanation:
Answer:
3/6, 5/10, 50/100 the rest are not held of the denominator
F= hypotenuse
E= opposite
G= adjacent
the plus sign (+) means above seal level
so the sign should say 2100 feet above sea level
Answer:
Step-by-step explanation:
You can rewrite the given log expressions to express them in terms of ln(a), ln(b), and ln(c). Then substituting the given values will produce the value of the expression.
Or, you can define the variables 'a', 'b', and 'c' and let your calculator compute these directly.

The applicable rules of logarithms are ...
- ln(ab) = ln(a) +ln(b)
- ln(a/b) = ln(a) -ln(b)
- ln(a^b) = b·ln(a)
- ln(a) = b ⇔ a = e^b
Of course, a square root is the same as a 1/2 power.
