Ineed to interpret the slope of the graph..

Rate of change of ambient temperature with respect to altitude.

Step-by-step explanation:

Interpretation:  As altitude above sea level increases (from zero to 15 thou of feet and beyond), the ambient temperature drops (from 75 degrees F to 0 and below).  Thus, the (negative) slope of this line signifies the rate of change of temperature with respect to altitude.

it is x equals 3   plese mark me really need it

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
