Answer:
Step-by-step explanation:
The given expression is
The tangent of -1 is defined, it's around -0.02.
The tangent is a trigonometric function with a period of 
, where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".
However, at 
, the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.
Answer:
She needs to buy 3 such containers.
Step-by-step explanation:
Mrs. Saledo wants to buy 
quarts of whipping cream.
Now, quarts = 
quarts = 
pints.
Since we know that 1 US liquid quart = 1 US liquid pints.
If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )
Answer:
x<3 and x≥5
Step-by-step explanation:
Look at the circles and what is shaded on the number line. The first circle is at x=3, and it's an open circle. An open circle means that the interval does not include that point. The arrow is going to the left, meaning x < 3.
The next circle is at x=5. It is a closed circle, so the interval does include that point (so draw a bar under the less than/greater than sign). Next, notice how the arrow is pointing to the right. That means that the blue area is at x=5 and greater than x=5, so x≥5.
