Answer:

an = 1/2 (4)^ (n-1)

a6 = 512

Step-by-step explanation:

The formula for a geometric sequence is

an = a1 (r)^(n-1)

where an is the term of the sequence

a1 is the initial term of the sequence

r is the ratio

and n is the term number

We know a1 = 1/2 and r =4

I will assume that x=6 means we want to know the 6th term

an = 1/2 (4)^ (n-1)

We want to find the 6th term

a6 = 1/2 * 4^(6-1)

a6 = 1/2 * 4^5

a6 = 512

Consider the table for the exponential function, LaTeX: p\left(x\right)=2^xp ( x ) = 2 x, shown below. Calculate the Average Rat
Mice21 [21]

Answer:

15

Step-by-step explanation:

To find the average rate if change of the exponential function between the interval [2, 6], use the formula, m = \frac{p(b) - p(a)}{b - a}

Where,

a = 2, p(2) = 4

b = 6, p(6) = 64

Plug in the above values into the formula:

m = \frac{64 - 4}{6 - 2}

m = \frac{60}{4}

m = 15

Average rate of change is 15

The polyhedron has 120 edges. How many vertices does it have?
Charra [1.4K]
(Correct me if I’m wrong in comments)

Answer: 80

Reasoning: A polyhedron can have 30 edges. If this polyhedron has 120 it has 4 times the “other” one. If it has 30 edges it will have 20 vertices, meaning 20*4=80 vertices
