What is the length of the marked portion of each line segment? Copy the segment onto your paper before finding the missing length. Assume that the entire line segment is subdivided into equal sections. 1. A line segment from 0 to you 75, divided in 3 equal sections. A bracket enclosed the first section, labeled with a question mark.

2. A line segment, from 0 to 75, divided into 5 equal sections. A bracket includes the first 3 sections, labeled with a question mark.

3. A line segment, from 0 to 50, divided into 5 sections. A bracket includes all sections, except the first and last, labeled question mark.

all but the second one

step-by-step explanation:

cuz that one goes over 180

mark brainliest

thats not a system of equations, that is a solution

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt

b. f(x) = –√x + 3this is the correct answer
