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:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
