The radius of a sphere is 6 inches. Find the length of a chord connecting two perpendicular radii. x = inches
Lilit [14]
<h3>Answer:</h3>

6√2 ≈ 8.485 inches

<h3>Step-by-step explanation:</h3>

The radii and the chord together make an isosceles right triangle with legs 6 inches long. The hypotenuse of such a triangle is √2 times the leg length. So, the chord will be 6√2 in long.

_____

<em>Comment on isosceles right triangle</em>

It is worth remembering that the hypotenuse of an isosceles right triangle is √2 times the leg length. This is easily found using the Pythagorean theorem:

... c² = a² + b²

... c² = 1² + 1² = 2 . . . . for legs of length 1

... c = √2 . . . . . . . . . . take the square root.

Scale this result as needed for any particular problem. Here, the scale factor is 6 inches.

Simplify the following expression and write it in an exponential function form.
Sergio039 [100]

Answer:

1/4 b^9

Step-by-step explanation:

(b^11 b^-7)/4b^-5

We know x^y * x^z = x^(y+z)

b^11 * b^ -7 = b^ (11-7) = b^4

(b^11 b^-7)/4b^-5

b^4 / 4 b^-5

We know x^y / x^z = x^(y-z(

b^4 / b^-5 = b^(4 - -5) = b^(4+5) = b^9

1/4 b^9

How to get the right answer
marusya05 [52]

Answer:

15 cm

Step-by-step explanation:

Write out the formula:                                     a^2 + b^2 = c^2

Plug in the numbers that you were given:    a^2 + 6^2 = 16^2

Solve for the numbers that you were given: a^2 + 36 = 256

Subtract:                                                                  - 36 = - 36

                                                                          a^2         = 220

Then, you find your answer:                            a^2 = 220

The square root of 220 is 14.832396974191326. But you are going to round it and you get 15. So, the answer is 15 cm.

Hope this helps
