Answer:

Radius

Step-by-step explanation:

Radius is the length from the mid point of a circle to the edge of the circle. You can see that segment JK goes from the middle of the circle to the edge

Answer: A

Step-by-step explanation: n geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant will intersect the circle at exactly two points.

A plane traveled 1794 miles to Bangkok and back. The trip there was with the wind. It took 13 hours. The trip back was into the

Burka [1]

Answer:

The speed of wind is 30 miles/hour

Speed of plane in still air is 108 miles /hour

Step-by-step explanation:

Distance traveled by plane to Bangkok = 1794 miles

The trip there was with the wind. Time taken = 13 hours.

The trip back was into the wind. The trip back took 26 hours.

Let s = plane speed in still air

let w = speed of the wind

(s+w) = speed of plane with wind

(s-w) = speed of plane against wind

Distance = Speed * Time

When the trip was with the wind .

⇒ $1794 =(s+w)\times13$

⇒ $\frac{1794}{13}=s+w$

⇒ $138=s+w$ ---1

When The trip back was into the wind.

⇒ $1794 =(s-w)\times23$

⇒ $\frac{1794}{23}=s-w$

⇒ $78=s-w$ ---2

Add 1 and 2

⇒s+w+s-w =138+78

⇒2s =216

⇒ $s=\frac{216}{2}$

⇒ $s=108$

To find w substitute the value of s in 1

⇒ $138=108+w$

⇒ $138-108=w$

⇒ $30=w$

Thus the speed of wind is 30 miles/hour

Speed of plane in still air is 108 miles /hour

The theoretical probability of an event is the number of desired outcomes divided by all possible outcomes. What is the probabil

malfutka [58]

The theoretical probaility of drawing an ace from a shuffled deck of playing cards is 1/13.

According to the given question.

A card is drawn from a shuffled standard deck.

Since, the total number of cards in a shuffled standard deck = 52

And, the total number of aces in a shuffled standard deck = 4

As, we know that "the theoretical probability of an event is the number of desired outcomes divided by all possible outcomes".

Therefore, the theoretical probabability of drawing an ace from a shuffled deck of playing cards

= 4/52

= 1/13

Hence, the theoretical probaility of drawing an ace from a shuffled deck of playing cards is 1/13.

Determine algebraically whether the function is even, odd, or neither even nor odd. f as a function of x is equal to x plus quan

Svetach [21]

y = x + 4/x

replace x with -x. Do you get back the original equation after simplifying. if you do, the function is even. replace y with -y AND x with -x. Do you get back the original equation after simplifying. If you do, the function is odd. A function can be either even or odd but not both. Or it can be neither one. Let's first replace x with -x

y = -x + 4/-x = -x - 4/x = -(x + 4/x)

we see that this function is not the same because the original function has been multiplied by -1 . Let's replace y with -y and x with -x

-y = -x + 4/-x

-y = -x - 4/x

-y = -(x + 4/x)

y = x + 4/x

This is the original equation so the function is odd.
