The domain of a sequence can include decimals and irrational numbers.

1 answer:

5 0

No, that's not true. The input variable of a sequence is called the index, which is a counter, such as 1, 2, 3, 4, ... Note that all of these counters are positive integers. Normallly I use index i = 1 to denote the first term of a sequence, i = 2 the second term, and so on.

Decimals and irrational numbers are completely unsuitable for serving as such counters.

Lemur [1.5K]

Answer:15 ft

Step-by-step explanation:

Given

The total perimeter needed is $40\ ft$

The available width of the room is $w=5\ ft$

Suppose l is the length of the room

So, the perimeter of a rectangle-shaped room is $2(l+w)$

Putting values

$\Rightarrow 40=2(l+5)\\\Rightarrow l+5=20\\\Rightarrow l=15\ ft$

A truck can be rented from company a is $120 a day plus $0.20 per mile. company b charges $40 a day plus &0.60 per mile to r

nadya68 [22]

First need to make an equation for each

x = Miles
y = Total Cost

Comp A: 120 + 0.20x = y
Comp B: 40 + 0.60x = y

cancel out the amounts to make it easier (Subtract 40 from each)

Comp A: 80 + 0.20x = y
Comp B: 0.60x = y

insert a problem for y to solve for x

80 + 0.20x = 0.60x

Your answer is 200 miles
