The value of a comic book has been increasing over time. Each year, the value increases by 30%. The original cost of
the comic book was $4.00
which function models the value of the comic book after years?

•V(n)=4+(0.3)^n

•V(n)=4+(1.3)^n

•V(n)=4(0.3)^n

•V(n)=4(1.3)^n

Find the equation using the point (4,8)

The distance of a chord from the centre of a circle is 12cm and the lenght of the chord is 10cm. find the radius of the circle

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
