Answer:
f(x) = -5x - 2
Step-by-step explanation:
Plug in the first set of values into each possible equation. Whichever equation yields the correct ouputs (y-values) for ALL input (x-values) is the correct answer. For the function f(x) = -5x - 2, f(-2) = 8, f(-1) = 3 and so on... So f(x) = -5x - 2 is the correct answer!
Hope this helps!
Answer:
1) D. 
2) E. The coefficient of 
is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form 
, where 
is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
Correct answer: D
2) Let 
, we proceed to expand the expression by algebraic means:
We see that coefficients for 
and are -16 and 0, respectively. Hence, the incorrect answer is E.
Answer 3.1
Here's the formula:
V=
H=3
3 · 
≈ 3.08333
rounded to : 3.1
(P.S. I also Used a calculator)
The arc sine of 0.5 is 30 degrees Therefore x = 30 degrees
The cosine of x = cosine of 30 degrees = 0.86603
(rounded to nearest hundredth is .87)
Sure the answer is obviously 9
