A person standing at the edge of a cliff throws a rock upward from a height of 180ft above ground level with an initial velocity of 64ft/s. Calculate the velocity of the rock when it is exactly 48ft above the person's hand. Separate multiple answers with a comma. (Hint: Use h(t)=−16t2+64t+180 as the position function, where h is in feet, t in seconds. Ignore air resistance.)

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'.

yes
