Answer:
48:26.075
Step-by-step explanation:
In an arithmetic sequence, the difference between consecutive terms is constant. In formulas, there exists a number
such that

In an geometric sequence, the ratio between consecutive terms is constant. In formulas, there exists a number
such that

So, there exists infinite sequences that are not arithmetic nor geometric. Simply choose a sequence where neither the difference nor the ratio between consecutive terms is constant.
For example, any sequence starting with

Won't be arithmetic nor geometric. It's not arithmetic (no matter how you continue it, indefinitely), because the difference between the first two numbers is 14, and between the second and the third is -18, and thus it's not constant. It's not geometric either, because the ratio between the first two numbers is 15, and between the second and the third is -1/5, and thus it's not constant.
Answer:
BCDA is equivalent to FGHE
A is equivalent to angle E
B is equivalent to angle F
C is equivalent to angle G
D is equivalent to angle H
Step-by-step explanation:
1st step is just figuring out which sides corresponds with which.
A is equivalent to angle E
B is equivalent to angle F
C is equivalent to angle G
D is equivalent to angle H
On the last one I am confused by what it is asking, but here is what I think:
The scale factor from the big figure to the small figure is 1.5 because of 15/10=1.5
12/8=1.5 and so on.
Answer:
a = 16.733
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
a^2 + 9^2 = 19^2
a^2 = 19^2 - 9^2
a^2 = 361-81
a^2 =280
Taking the square root of each side
sqrt(a^2) = sqrt(280)
a = 16.73320053
Rounding to the nearest thousandth
a = 16.733
