There is no answer because there cannot be one to one function inverse.
Centralangle/360 times area of circle=sector area
120/360 times pi8²=
(1/3)(64pi)=64pi/3 square inches
Answer:
rhombus = a quadrilateral with four congruent sides
rectangle = a quadrilateral with four right angles
parallelogram = a quadrilateral with two pairs of parallel sides
trapezoid = a quadrilateral with one set of parallel sides
square = a quadrilateral with four right angles and four congruent sides
4/5, because to simplify a decimal, you can divide the numerator by the denominator. 4 divided by 5 is 0.8
N³ - 2n² - 15n = 0
"n"
n (n² + 2n - 15) = 0
n = 0
n² + 2n - 15 = 0
Δ = (2)² - 4(1)(-15)
Δ = 4 + 60 = 64
n' = (-2+8) / 2 = 6/2 =3
n'' = (-2-8) / 2 = -10/2 = -5
Solution:
S {-5 , 0 , 3 }
