Fernando invested money in a 4-yr CD (certificate of deposit) that returned the equivalent of 5.2% simple interest. He invested $3000 less in a 18-month CD that had a 3% simple interest return. If the total amount of interest from these investments was
$1130.00, determine how much was invested in each CD.
Fernando invested S

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'.
