Sierra is selling bracelets to raise money for the Language Club at school. Each bracelet with yellow beads sells for $5.
Each bracelet with orange beads sells for $6. She raised $660 for the club. The number of bracelets with yellow beads that
Sierra sold is 8 more than twice the number of bracelets with orange beads. Let y represent the number of bracelets with
yellow beads and represent the number of bracelets with orange beads Which system of equations will solve for the
number of each type of bracelet sold?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
