WILL GIVE BRAINLIST 2 BEST ANSWER
kolezko [41]

Answer:

M

Step-by-step explanation:

We have been given side AB and BC

AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).

BC must be also 6 as it starts at -4 and ends at 2.

Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)

C is the hypotenuse (longest side) and this is what we are trying to find...

6^2 + 6^2 = 36+36=72

So AC is 72, however we need to square root this to get our final answer.

72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...

AC is 6 root 2

Hope this helps!

the tempature rises 36° F. each hour the tempature rises 6°F. write an equation that models the tempature y, in degrees Fahrenhe
aleksklad [387]
Since the temperature starts at 40 degrees F at sunrise and increases 4 degrees every hour afterward, we can begin our equation.

If you visualize the graph, the y-axis (left side) will denote the degrees and increase slightly every hour. The x-axis (at bottom) will show the hours as they pass by. In slope-intercept form, the b must be 40 degrees, since this is where we start, and the slope m must be 4, since this is the amount the temperature is changing every hour.

Therefore y=4x+40

This equation will tell you the temperature (y) at any hour (x).
