SpyIntel [72]
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))

The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)

S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi

Let us split the middle term as:

2x^2 + 8x + x+4\\\\2x(x+4)+1(x+4)\\\\(x+4) (2x+1)

Therefore, factors of the given expression are (x+4), (2x+1)

Find the circumference of the circle .the diameter is 6cm
Vinvika [58]

Answer:

18.84cm

Step-by-step explanation:

There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3.

So 3x2x3.14=18.84cm

So then you could just multiply 6x3.14 and still get 18.84cm
