Answer:
K = (1/2)r^2(sin(θ) +θ)
Step-by-step explanation:
The area of the triangle to the left is ...
A1 = (1/2)r^2·sin(180°-θ) = (1/2)r^2·sin(θ)
The area of the sector to the right is ...
A2 = (1/2)r^2θ
so the total area of the blue shaded region is ...
K = A1 + A2 = (1/2)r^2·sin(θ) + (1/2)r^2·θ
K = (1/2)r^2(sin(θ) +θ)
Answer:
Step-by-step explanation:
-25/8 minus 5/2
(You just turn them into improper fractions)
Answer:
In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate, x, is x^2 − 4x + 7.
We need to find that the probability that the person is male or frequently involved in charity work.
From the attached figure,
Total no of people = 2881
No of Males = 1479No of females who are frequently involved = 205 ∴ Total no. of males or frequently involved = Sum of both
= 1479 + 205
= 1684∴ Probability =
=
∴ Probability = 58.45%
