1) Find the sum of the following geometric sequence:

1 + 4 + 16 + 64 + ... + 4096

2) What is the nth term of the sequence
− 1, 3, 7, 11,...?
1) an =−1−4(n−1)
2) an =−1+4(n−1)
3) an =4−(n−1)
4) an =4+(n−1)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

tangent

step-by-step explanation:

0.85% : )

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
