Step-by-step explanation:
R = 3x + 9y
When y = 6 and R = 7
7 = 3x + 9.6
7 = 3x + 54
7 - 54 = 3x
-47 = 3x
x = -47/3
A₁ = -8 This is the first term in an arithmetic sequence.
d = 3, the common difference
a(n) = a₁ + d(n-1)
a₇ = -8 + 3(7-1)
a₇ = -8 + 3(6)
a₇ = -8 + 18
a₇ = 10
To check:
a₁ = -8
a₂ = -8 + 3 = -5
a₃ = -5 + 3 = -2
a₄ = -2 + 3 = 1
a₅ = 1 + 3 = 4
a₆ = 4 + 3 = 7
a₇ = 7 + 3 = 10
Answer:
Therefore the approximate area of this clock face is 415.3 feet².
Step-by-step explanation:
Given:
Clock is of Circular Shape,
Diameter = 23 feet

To Find :
Area of Clock Face = ?
Solution:
Area of Circle having Radius 'r' is given as,

Substituting the values we get

Therefore the approximate area of this clock face is 415.3 feet².
Basically, shift each coordinate one unit to the right (one X over)
You will have to predict the points a little
