Answer:

k = 2

Step-by-step explanation:

Based on the right triangle altitude theorem, thus:

4 = √(k*8)

Square both sides

4² = k*8

16 = 8k

Divide both sides by 8

16/8 = 8k/8

2 = k

k = 2

City R has a temperature of -2 degrees. City S has a temperature of -6 degrees. Write an inequality to compare the temperatures

elena-s [515]

Answer:

-2 > -6 . . . or . . . R > S

Step-by-step explanation:

If you plot the temperatures of the two cities on a number line, you see that the temperature for City R is plotted to the right of the temperature for City S. This means the temperature of City S is less than that of City R.

If your inequality relates cities:

S < R or R > S

If your inequality relates temperatures:

-6 < -2 or -2 > -6
