Answer:
x = 240°, x = 300°
Step-by-step explanation:
Using the identity
sin x = 
= 
= - 
, then
x = 
( ) = 60° ← related acute angle
Since sin x < 0 then x is in 3rd / 4th quadrants
x = 180° + 60° = 240°
x = 360° - 60° = 300°
Answer:
C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number
Step-by-step explanation:
Rational function: In mathematics, the term "rational function" is determined as any specific function that can be described through any "rational fraction", in other words, an algebraic fraction, involving both the denominator and the numerator are considered as polynomials. Therefore, the coefficients of specific polynomials are ought not to be in rational numbers and can be considered in the K field.
In the question above, the given statement represents option C is correct.
Answer:
193
Step-by-step explanation:
9, the tens digit, is six more than 3, the ones digit. 1, the hundreds digit, is 8 less than the tens digit, 9. It can't be any other number combination than this.
Hope this helps! :)
Answer:
5-3x
Step-by-step explanation:
To expand this, we start with the distribution of -3 into the parentheses containing x+2
This leaves us with
11-3x-6
From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6
We combine them by subtracting 11-6 to get 5.
This leaves us with our answer,
11-6-3x
<u>5-3x</u>
An alternate way of writing this would be
<u>-3x+5</u>
But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now
I think it's already in expanded form.
