The total amount of cable used is 47.4m
<u>Explanation:</u>
Given:
Amounts of cable used that has to be rounded off to 1 decimal place:
12.995 m ≈ 13.0 m
7.505 m ≈ 7.5m
10.08 m ≈ 10.1 m
6.95 m ≈ 7.0 m
9.75 m ≈ 9.8 m
Total amount of cable used = 13m + 7.5m + 10.1m + 7m + 9.8m
= 47.4m
Therefore, total amount of cable used is 47.4m

Answer:
<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ =
0</h3>
Step-by-step explanation:
Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰
S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰
S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀
then, S is the sum of 100 consecutive terms of a geometric sequence (an)
where the first term a1 = i¹ = i and the common ratio = i
FORMULA:______________________

_______________________________
then

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)
Hence
S = 0

Downstream
5.2=(x+y)2.5
Step-by-step explanation:
Answer:
Una relación lineal es de la forma:
y = a*x + b.
donde a es la pendiente y b es la ordenada al origen.
en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.
Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:
$21,000 = a*5 + $42,000
a*5 = $21,000 - $42,000 = -$21,000
a = -$21,000/5 = -$4,200
Esto significa que el precio decae $4,200 por año
