bazaltina [42]2 years ago
7 0

Answer:

20

Step-by-step explanation:

According to Euclidian theorem:

h^2 = AD*CD (h is the height, DB in this case)

rewrite the equation by using given values

10^2 = 5*CD find the square value of 10

100 = 5*CD divide both sides by 5

20 = CD

Roman55 [17]

Answer:

x=91, y=91, z=39

Step-by-step explanation:

the angles add up to 180 so find the difference ex. 51+38=89, 180-89=91 so x is 91

express 121,200 in exponential (powers of 10) notation. express the earth sun distance in kilometers in powers of 10 notation.
Mashutka [201]

The exponential form of given number 121200 is 1.212 × 10^5

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × 10^8

For given question,

We need to express 121,200 in exponential (powers of 10) notation.

To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.

The number between 1 and 10 in 121200 is 1.212 with 5 decimal points.

So, the exponential notation of given number would be,

121,200 = 1.212 × 10^5

Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.

So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.

So, the distance between he Earth and the Sun is:

150,000,000 = 1.5 × 10⁸

Therefore, the exponential form of given number 121200 is 1.212 × 10^5

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × 10^8

Which of the following is equal to the rational expression when x ≠ -4 or 16?
stepan [7]

Answer:

C

Step-by-step explanation:

Given

\frac{x^2-16}{(x-16)(x+4)}

The numerator is a difference of squares

x² - 16 = (x - 4)(x + 4)

= \frac{(x-4)(x+4)}{(x-16)(x+4) } ← cancel the common factor (x + 4) on numerator/ denominator

= \frac{x-4}{x-16} → C
