When Nicole left her house in the morning, her cell phone battery was partially charged. The charge remaining in Nicole's battery, as a percentage, can be modeled by the equation B=-9t+72, where t is the number of hours since Nicole left her house. What is the slope of the equation and what is its interpretation in the context of the problem?

Step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

lol.

it's ok we all do this sometimes.
