Answer:
≈ 397 m
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Let h represent the height of the balloon above ground, then
h² + 50² = 400², that is
h² + 2500 = 160000 ( subtract 2500 from both sides )
h² = 157500 ( take the square root of both sides )
h ≈ 397 m ( to the nearest metre )
Answer: 
Step-by-step explanation:
<u>Given function</u>
f(x + 1) = x + 2
<u>Isolate [ x + 1 ] on the right-hand side</u>
f(x + 1) = x + 1 + 1
f(x + 1) = (x + 1) + 1
<u />
<u>Substitute [ x + 1 ] with x</u>
f(x) = x + 1
<u>Substitute [ x ] with [ x - 1 ]</u>
f(x - 1) = (x - 1) + 1
Hope this helps!! :)

Answer:
B. 5 inches
Step-by-step explanation:
This is because of the triangle inequality theorem which states "The sum of the lengths of any two sides of a triangle is greater than the length of the third side." So, since 5+9 is 14 it has to be less than 14. Also, because 5+2 is 7 and that is not greater than 9 it has to be 5 inches.
