Step-by-step explanation:
Answer:
2485
Step-by-step explanation:
The number of seats in row n is given by the explicit formula for an arithmetic sequence:
an = a1 +d(n -1)
an = 20 +3(n -1)
The middle row is row 18, so has ...
a18 = 20 + 3(18 -1) = 71 . . . . seats
The total number of seats is the product of the number of rows and the number of seats in the middle row:
capacity = (71)(35) = 2485
The seating capacity is 2485.
log(x) + log(3) = log(18)
log(x) + 0.477121 = 1.255273
Add -0.477121 to both sides.
log(x) + 0.477121 + −0.477121 = 1.255273 + −0.477121
log(x)+0 = 0.778152
Divide both sides by 1.
log(x)+0/1 = 0.778152/1
log(x)=0.778152
Solve Logarithm
log(x) = 0.778152
10log(x) = 100.778152
x = 100.778152
x = 6.00001
move all terms to the left side and set equals to zero. then set each factor equal to zero
