I don’t understand pls help!!
mezya [45]

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63  Square root both sides to get b by itself.

b = 7.93725

Answer is 7.9 meters, rounded to tenths place

Find the simplified form of the expression. Give your answer in scientific notation.
maksim [4K]
It's answer will be 36x10^5 As we have (4x10^10)(9x10^-5) All terms of this expression are being multiplied So we will solve it in two parts, simple terms and terms having powers (4x9)(10^10x10^-5) As we know when same terms having some powers are multiplied, their powers are added (36)(10^(10-5)) (36)(10^5) So it will become 36x10^5
