You must simplify it to find the answer. You get 2 over 1 which equals just 2.
Answer:
Step-by-step explanation:
A recursive formula is a formula in which each term is based on the previous term.
In a geometric sequence, each term is found by multiplying the previous term by a constant.
To get from 27 to 9, then from 9 to 3, etc., we would multiply by 1/3. This makes the common ratio 1/3.
The recursive formula for a geometric sequence is
, where 
represents the general term, 
, represents the previous term, and r represents the common ratio.
Plugging in our values, we have
We also have to indicate what the first term, a₁, is. In this sequence, it is 21. This gives us
Answer:
(x-5)^3
Step-by-step explanation:
(x-5)^3. (x−5)3 ( x - 5 ) 3
Answer:
The circumference of the circle is 5π
Step-by-step explanation:
First we need to calculate the diameter
for this we have to know the distance between A(1, 3) and B(4, 7)
X = Xb - Xa
X = 4 - 1
X = 3
Y = Yb - Ya
Y = 7 - 3
Y = 4
b - a = (3 , 4)
now that we have the distance of x and r we can calculate its distance using Pythagoras
h = hypotenuse
x = leg 1 = 3
y = leg 2 = 4
h² = x² + y²
we replace the known values
h² = (3)² + (4)²
h² = 9 + 16
h² = 25
h = √25
h = 5
The diameter of the circle is 5
Now we need to calculate the circumferencefor this we need to use the circumferenc formula of a circle:
c = circumference
d = diameter = 5
π = pi
c = π * d
we replace with the known values
c = 5 * π
c = 5π
The circumference of the circle is 5π
9xh = total cost of the hat
9 per hat - 4 = $5 each scarf
h = hat
s = scarf
(9xh) + (5x s)
(9x7) + (5x9) = 108
