Answer:
Step-by-step explanation:
We are trying to find the hypotenuse of a right triangle
We will use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
11^2 + 7^2 = c^2
121 + 49 = c^2
170 = c^2
Taking the square root of each side
To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17. The height of the tree after ten years was 17 meters tall in height.
Hello!
In this problem, we will need to know our properties of exponents.
When we multiply two exponents, for example 10^3 × 10^-1, we will need to add the powers together. So, 10^3 × 10^-1 = 10^2 or 100.
With this, we can multiply the two constants together, and the exponents together to find our quotient.
(8.2 × 10^-6) × (9.4 × 10^-3) (rearrange the expression)
8.2 × 9.4 × 10^-6 × 10^-3 (multiply)
77.08 × 10^-9
If you wanted your answer to be in scientific notation, move the decimal place in 77.08 one place to the left, leaving you with 7.708 × 10^-8.
Therefore, your final answer is 7.708 × 10^-8.
