Answer:
x=12
Step-by-step explanation:
x+27=29
x=29-17
x=12
Example: Convert 0.125 to percent. Multiply 0.125 by 100: ...Example: Convert 0.35 to percent. Move the decimal point two places to the right: 0.35 → 3.5 → 35. ...Example: Convert 0.985 to percent. ...Example: Convert 1.2 to percent
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
Answer:
f(x) = 8 - 1.5x
Step-by-step explanation:
Here, we want to write a function that can be used to describe the x th term of the sequence
Mathematically, this can be calculated by looking at the numbers in the sequence
The difference between each successive term
is -1.5 ( 6.5-8, 3.5 -5)
So the formula for then x th term will be;
f(x) = 8 - 1.5x
where x refers to the number of the term , for example the 4th term
Well, mode means most frequent number within the set so since there is two 18's that is your mode.
