4. Use the diagram below to answer the question
ludmilkaskok [199]

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 )

If f(x + 1) = x + 2 then f(x - 1) is
erastova [34]

Answer: \Large\boxed{f(x-1)=x}

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

\Large\boxed{f(x-1)=x}

Hope this helps!! :)

Two sides of a triangle measure 5 inches and 9 inches. Which of the following is a measure of a possible 3rd side of the triangl
svet-max [94.6K]

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.
