Answer:

a = 65 yd is the answer.

Step-by-step explanation:

a = ?

b = 72 yd

c = 97 yd

According to the Pythagoras theorem,

a² + b² = c²

a² + 72² = 97²

a² + 5184 = 9409

a² = 9409 - 5184

a² = 4225

a = 65 yd

∴ a = 65 yd is the length of the missing leg.

A plane traveled 1248 miles to Ft. Worth and back. The trip there was with the wind. It took 12

Artemon [7]

speed of the plane in still air is 76 m/s and speed of the wind is 28 m/s .

Step-by-step explanation:

Here we have , A plane traveled 1248 miles to Ft. Worth and back. The trip there was with the wind. It took 12 hours. The trip back was into the wind. The trip back took 24 hours. We need to find What is the speed of the plane in still air? What is the speed of the wind? Let's find out :

For Going trip :

Let speed of plane be u , and wind be v so : Speed = ( Distance ) / ( time )

⇒ $u+v = \frac{1248}{12}$

⇒ $u+v = 104$ ...........(1)

For Returning Trip :

⇒ $u-v = \frac{1248}{24}$

⇒ $u-v = 52$ ...........(2)

Adding both equations we get :

⇒ $(u+v)+(u-v)=104+52$

⇒ $2u=156$

⇒ $u= 76m/s$

Putting this value in equation (1) we get :

⇒ $76+v = 104$

⇒ $v=28m/s$

Therefore , speed of the plane in still air is 76 m/s and speed of the wind is 28 m/s .

Which transformation are needed to change the parent cosine function to y=3cos(10(x-pi))

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

First, we can transform y = cos(x) to y = 3*cos(x) by stretching the graph vertically by a factor of 3. At x = 0, the y value would now be 3 * 1 = 3 instead of 1 (the stretching would cause all new y-values to be 3 times their original values for any given x).

Now transforming y = 3*cos(x) to y = 3*cos(10*x) will stretch the graph horizontally by a factor of 10 (for any given y value, the new x value corresponding to it is 10 times the original x value).

Finally, to transform y = 3*cos(10*x) to y = 3*cos(10(x-pi)), shift the graph to the right by pi.

One ball is to be selected from a box containing red, white, blue, yellow, and green balls. If the probability that the selected

ZanzabumX [31]

Answer:

30% probability that it will be yellow, or green

Step-by-step explanation:

The urn has red, white, blue, yellow, and green balls.

Each ball is chosen with the following probabilities:

1/10 = 10% probability it is red

2/5 = 40% probability it is white

1/5 = 20% probability it is blue.

p probability it is yellow or green

What is the probability that it will be yellow, or green

The sum of all probabilities is 100%. So

10 + 40 + 20 + p = 100

p = 30

30% probability that it will be yellow, or green
