Answer:

No, we can not construct a tangent line that passes through a point A inside the circle C.

Step-by-step explanation:

Tangent line:A tangent line to a circle is define as the  straight line which touches the circle at one point only. The tangent to a circle is perpendicular to the radius of circle .

The point at which tangent touches the circle is called point of contact.

If we construct a line inside the circle C and passes through point A .The constructing line not a  tangent line to a circle .

Because by definition of tangent to a circle

The constructing line does not touch the circle at one point and the point is called point of contact . The constructing line not perpendicular to radius at point of tangency.

The constructing line is a simple line not tangent which passes through a point A inside the circle C.

Therefore , we can not construct a tangent line passing through a point A inside the circle C.

Answer:

No

Step-by-step explanation:

A tangent line is a line entirely exterior to the circle except for the one point of intersection that lies on the circle. It does not (and cannot) go through any points inside the circle.

Which of the following has a positive value? sec (2pi/3) tan (2pi/3) cos (2pi/3) csc (2pi/3)
Darya [45]

Answer:  D) csc (2π/3)

<u>Step-by-step explanation:</u>

2π/3 is in Quadrant II

Quadrant II has a negative x-value and a positive y-value.

x-values are: cos & sec

y-values are: sin & csc

tan = y/x so will be negative in Quadrant II

A) sec = -

B) tan = -

C) cos = -

D) csc = +     this works!

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop?
konstantin123 [22]

Answer:

Coffee(time)

Step-by-step explanation:

A function's output variable will be:

output(input)

So we need to find the input variable and the output variable.

We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.

The time of day then becomes our input as the coffee sold relies on that number.

That leaves coffee sold as our output!

So the best name for a function in this scenario is Coffee(time).

Hope this helped!

Kimiya has four times as many marbles as Ramneet. If kimiya gave 18 to Ramneet they would have the same number. How many marbles
RSB [31]

Answer:

Kimiya has 48 marbles, Ramneet has 12 marbles

Step-by-step explanation:

kimiya has 4x marbles ramneet has x marbles then 4x - 18 = x + 18 because if you give 18 marbles from kimiya to ramneet then you subtract 18 from kimiya and add 18 to ramneet by solving the equation you will get x as 12.So kimiya has 48 marbles, ramneet has 12 marbles.
