Answer:

Option 2 and 4

Step-by-step explanation:

Given : Function's graph has asymptotes located at the values x=\frac{\pi}{2}\pm n\pi

To find : Which function graph has asymptote given?

Solution :

An asymptote is a line or curve that approaches a given curve.

To find vertical asymptote the limit has to go to either  ∞  or  − ∞  , which happens when the denominator becomes zero.

The sine are defined for all real x, y is defined for all real x, so there are no vertical asymptotes.

So, Option 1 is not true.

In option 3,

y=\cot x=\frac{\cos x}{\sin x}

When we put Denominator = 0

\sin x=0

Value of x lie between (0,n\pi)

So, Option 3 is not true.

In Option 2,

y=\sec x=\frac{1}{\cos x}

When we put Denominator = 0

\cos x=0

When cos x=0 the values of x is

x=\pm\frac{\pi}{2},\pm\frac{3\pi}{2},\pm\frac{5\pi}{2},.....

x=\frac{\pi}{2}\pm n\pi

Therefore, The graph of y= sec x has asymptote located at the values x=\frac{\pi}{2}\pm n\pi

So, Option 2 is correct.

In Option 4,

y=\tan x=\frac{sin x}{\cos x}

When we put Denominator = 0

\cos x=0

When cos x=0 the values of x is

x=\pm\frac{\pi}{2},\pm\frac{3\pi}{2},\pm\frac{5\pi}{2},.....

x=\frac{\pi}{2}\pm n\pi

Therefore, The graph of y= tan x has asymptote located at the values x=\frac{\pi}{2}\pm n\pi

So, Option 4 is correct.

Therefore, Option 2 and 4 are correct.

Hence Option A is correct - 2 only

if the store purchased a kitchen appliance for $42 and sold it for $58.80, what was the percent markup?
oksano4ka [1.4K]

Answer:

40%

Step-by-step explanation:

Percent markup = new price - original price/original price

Do the subtraction first.

58.80 - 42.00 = 16.80

Now do the division

16.8/42 = 0.40

Change the decimal to a percent by moving the decimal two place to the right.

0.40 = 40%

Using the formula C=2pi r find the circumference of a circle with diameter of 28 inches. Round your answer to the nearest inch.
Ivenika [448]

Answer: 88 inches

Step-by-step explanation:

We know that the formula to find the circumference of circle is given by :-

C=2\pi r, where r is the radius of the circle.

Given : Diameter of circle = 28 inches

Also, diameter is twice of radius.

i.e. 2r=28

Therefore, the circumference of circle will be :-

C=2\pi r=(2r)\pi=28\times(3.14)=87.92text{ inches}\approx88\text{ inches}

Hence, the  circumference of circle is 88 inches.

Name the property used to make the conclusion. If x+ 3 = 17, then x = 14 -
zimovet [89]

Answer:

Subtraction property of inequality

Step-by-step explanation:

Step 1: Definition of Subtraction property

Subtraction property of equality refers to balancing an equation by using the same mathematical operation (minus) on both sides.

Step 2: Relate the definition above with the given question.

It can be seen from the statements in the question that 3 was subtracted from both sides of the initial equation to get:

x + 3 = 17 \\ x + 3 - 3 = 17 - 3 \\  x = 14
