cosx>0 in the 1st and 4th quadrant.
tanx>0 in the 1st and 3rd quadrant.
therefore the common solution is x lies in 1st quadrant.
Hence the correct answer is option A.
Hope this helps
Answer:
-1 and 10
Step-by-step explanation:
I just took the quiz
With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170 ( correct )
D ) 0.15 * 200 = 30
30 = 30 ( correct )
Answer:
A ) 0.15 x = x - 30
Good question sir but idk
The value of f(0) is 1
and
The roots of f(x) = 0 are -2 and -1
<h3>Graph of a function</h3>
From the question, we are to determine the value of f(0) and the roots of f(x) = 0
The value of f(0) is the value of f(x) or the value of y when x = 0
In the given graph, we can observe that the value of y when x = 0 is 2
∴ f(0) = 2
The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0
In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1
∴ The roots of f(x) = 0 are -2 and -1
Hence, the value of f(0) is 1
and
The roots of f(x) = 0 are -2 and -1
