N would be equal to 3.2. Hope this helps
Answer: the explicit formula is
Tn = 3 + 5(n - 1)
Step-by-step explanation:
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + d(n - 1)
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 3
d = 8 - 3 = 13 - 8 = 18 - 13 = 5
The explicit formula for the arithmetic sequence is
Tn = 3 + 5(n - 1)
Answer:
(15/360)*whatever the circumferance is
Step-by-step explanation:
Length of arc = 2π * radius * angle/360
And 2π * radius= circumference
Therefor we can replace that in the eqaution so we can do
circumference *angle/360=lengnth of arc
First find the volume of brick = 18 * 9 * 6 = 972 cm^3
volume of wall
Take note of units in meters. 1m = 100 cm
so we have 4.5 * 100 * 18 * 3.6 * 100 = 2,916,000 cm^3
So we divide the volume of wall by volume of brick to know how many bricks required
2,916,000/972 = 3,000 bricks

<u>Answer</u> :-</h2>
To find the cost of planting grass , we have to find area of the field.
Area of field = Length × Breadth
Now convert into hectare.
1 hectare = 10000m sq.
51000 / 10000
So area field = 5.1 hectare sq.
Now cost = 5.1 x 0.80 p
