Answer:1/9
Step-by-step explanation:
243,27,3,1/2,1/27,...
Common ratio=2nd term ➗ 1st term
common ratio=27 ➗ 243
Common ratio=1/9
Answer:
sinθ = c/b is the only correct answer
Step-by-step explanation:
all other terms have the ratio inverted.
A= The width times the length
159 3/8= 18 6/8(I just put it into 8ths instead of fourths to make it easier) • X
Divide by 18 6/8 for both sides which will give you your X.
Meaning the 18 6/8 will cancel out on the one side. So that you can solve for that length(I would solve it but I don't have a calculator).
Answer:
or 
Step-by-step explanation:
Given
Required
Solve for x using:
First, we need to identify a, b and c
The general form of a quadratic equation is:
So, by comparison with
Substitute these values of a, b and c in
Split the expression to two
or
To solve further in decimal form, we have
or 
or 
or 
I believe the answer would be a(a-4)(a-13)
I started with the a^3 - 17a^2 + 52a and factored out an "a"
---> a(a^2 - 17a +52)
Then I factored the expression in parentheses (*To factor it, you need to find out what multiplies to become 52 and adds to become 17*) And you get -4 and -13
---> a(a-4)(a-13)
