The short leg is 7ft and the longer leg in 14, i believe because if im not mistaken the long leg in a right triangle is 2 times the short one
If log2 (x-3) =1
It means that:
2^1 = x-3
2=x-3 |+3 to both sides
2+3=x
x=5
Answer:5.6 x 10^5
Step-by-step explanation:
When ever we hear sum, what comes to our mind must be addition
Here we are Adding 5.3 x 10 to the fifth power= 5.3 x 10^5 to
3.8 x 10 to the fourth power = 3.8 x 10^4
First,
Expanding the scientific notation we have that
5.3 x 10^5 = 530,000
3.8 x 10^4= 38,000
Add = 568,000
Putting back in Scientific notation we have 568000 = 5.6 x 10^5
