Answer:
The chocolate bar contains 29.2 grams of cocoa.
Step-by-step explanation:
Given that Lucy’s chocolate bar is 54% cocoa and the weight of the chocolate bar is 54 grams.
Hence, the amount of cocoa in the chocolate bar is given by
54% of 54 grams
54% percentage means 54/100 = 0.54
Hence, the amount of cocoa in the chocolate bar is
When rounded to the nearest tenth, 29.16 should be equal to 29.2
Hence, the chocolate bar contains 29.2 grams of cocoa.
Answer:
We are given the tangent function .
Firstly we know that, , where
is the sine function and
is the cosine function.
Now, tangent function will be zero when its numerator is zero.
i.e. when
.
i.e. when
, where n is the set of integers.
So, tangent function crosses x-axis at , n is the set of integers.
Further, tangent function will be undefined when its denominator is zero.
i.e. when
.
i.e. when
, where n is the set of integers.
Moreover, a zero in the denominator gives vertical asymptotes.
So, tangent function will have vertical asymptotes at , n is the set of integers.
Therefore, these key features gives us the graph of a tangent function as shown below.
