Please Help! In which of the following intervals does the trigonometric inequality sec(x)

Mathematics
1 answer:
timofeeve [1]2 years ago
3 0

Step-by-step explanation:

sec(x) = 1/cos(x)

cot(x) = cos(x)/sin(x)

sec is smaller than cot, if cos is negative (making sec negative) and sin is negative (making cot positive).

and that is true for the third quadrant.

which is pi < x < 3×pi/2

so, the third answer is right.

The price of an item has been reduced by 40%. The original price was $60. What is the price of the item now?
erik [133]
To reduce the item by 40%, you first need to find the 40% of 60. Multiply 0.4*60 and you will get 24. That is 40%. Now you need to subtract that from the original. 60-24 is 36 dollars and that is your answer.

Answer:

y=-6.6 and y=10.6

Step-by-step explanation:

The given ellipse has equation:

\frac{(y-2)^2}{64}+\frac{x^2}{9}=1.

The center of this ellipse is (h,k)=(0,2)

We use the equation: a^2-b^2=c^2 to determine the foci.

\implies 64-9=c^2

\implies 55=c^2

\implies c=\pm \sqrt{55}

The directrices are given by y=k\pm\frac{a^2}{c}

y=2\pm\frac{64}{\sqrt{55}}

y=2\pm8.6

y=2-8.6 and y=2+8.6

The equation of the directrices are:

y=-6.6 and y=10.6

The correct answer is D
