Answer:
630
Step-by-step explanation:
The sum of an arithmetic sequence is given by ...
Sn = n(2a1 +(n-1)d)/2
For the sequence of numbers of bales, we have ...
a1 = 123, d = -11, n = 7
so the total number of bales in 7 trips around the field is ...
S7 = 7(2·123 +6(-11))/2 = 630
The total number of bales made is about 630.
_____
123 + 112 + 101 + 90 + 79 + 68 + 57 = 630
-4y = 8x
Divide both sides by -4
y = -2x
This is in the form of y = kx, where k is the constant of variation.
y = kx is the direct
That means, k = -2.
The constant of variation is B. -2.
All you have to do is plug in 4 where n is
In other words n = 4
So...
F(n) = 5^n
F(4) = 5^4 or (5 x 5 x 5 x 5)
F(4) = 625
Y=3x + 8.25

Answer:
C
Step-by-step explanation:
the decimal would have to move 9 times from the zero position to get to between 5 and 8.
so 5.82 x 10^9
