The moon is approximately 221,000 miles from the Earth. Drag the tiles to represent 221,000 in scientific notation.
1 answer:
The scientific notation is .
Solution:
Let us first define the scientific notation.
Scientific notation is used to write large numbers in a small manner.
Rule to write the Scientific notation:
- Write one number before the decimal point.
- Count the zeroes and number after the decimal point.
For example:
500 can be written as 5 × 10².
6500 can be written as 6.5 × 10³.
Given data:
Distance from Earth to Moon = 221,000 miles
To write this in a scientific notation.
221,000 =
Hence the scientific notation is .

Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:
We can solve for x shown below:
The value of x is -2
