Shane marched 3 m East and 6 m north. How far is he from his starting point. Round your answer to the nearest tenth.
Dennis_Churaev [7]

Answer:

The distance from his starting point is  <u>6.7 m</u>.

Step-by-step explanation:

Given:

Shane marched 3 m East and 6 m north.

Now, to get the distance from his starting point.

Let the distance from the starting point be x.

Now, to solve using pythagorean theorem:

AB^2+BC^2=AC^2

6^2+3^2=x^2

36+9=x^2

45=x^2

<em>Using square root on both sides we get:</em>

6.71=x\\\\x=6.71\ m.

<u>So, the distance from the starting point nearest to tenth is 6.7 m.</u>

Therefore, he is 6.7 m from his starting point.

Determine f(9/2) for the function f(x)=3x-5
ANEK [815]

Answer:

f(9/2) = 17/2

Step-by-step explanation:

f(x) = 3x-5

let x=9/2

f(9/2) = 3*9/2 -5

f(9/2) = 27/2 - 5

get a common denominator

f(9/2) = 27/2 - 10/2

f(9/2) = 17/2
