Okay,
So we know how many pizzas they sold throughout the week, we add those together.
93
67
78
44
<u> 123</u>
405
You divide "405" by the amount of numbers there are.
so "5" into "405"
5 goes into 40 8 times
now we have 5 into 5 which goes 1 time.
Our answer is a solid 81.
To check our work, we can multiply 81 by 5.
5*1=5
5*8=40
405.
A. 81 is your answer
Explicit rule:
a(n)=(2/5)(5^(n-1))
For a recursive rule, we need to express a(n) in terms of a(n-1), which we can obtain from the explicit rule
a(n)=(2/5)(5^(n-1))
substitute n-1 for n above
a(n-1)=(2/5)(5^((n-1)-1))
=(2/5)(5^n-2)
Divide:
a(n)/a(n-1)=(2/5)(5^(n-1)) / ((2/5)(5^(n-2)))
=1/5^(-1)
=5
Therefore, multiplying both sides by a(n-1)
a(n)=5 a(n-1)
a(1)=(2/5)(5^(1-1))=2/5
So the recursive rule is
a(1)=2/5, a(n)=5 a(n-1)
Answer: x = 27/2
Step-by-step explanation:
2/3x-2=7
2/3x=9
2/3x=27/3
2/3x(3/2)=27/3(3/2)
x=81/6
x=27/2
X-intercept is (-6, 0) , (3, 0)
144 cm^2
Bottom 32 + slant 40 + 2 sides 24 each + back 24
