The area of the shadedregion is (area of the circle) - (area of the square) - (area of the triangle)
Option A is the correct answer
A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The shadedregion consists of the area inside the circle but outside the square, as well as the area inside the equilateral triangle but outside the square.
Now,
The area of the circle is πr²
Since the square is inscribed in the circle, the diameter of the circle is equal to the diagonal of the square.
Let's say the side length of the square is s.
By the Pythagorean theorem,
s² + s² = (diameter)²
2s² = (2r)²
s² = r²
The area of the square is s² = r².
The area of an equilateraltriangle with side length s is √(3)/4 x s².
Since the side length of the square is equal to the height of the equilateral triangle, the side length of the equilateral triangle is also equal to s.
The area of the shadedregion.
= (area of the circle) - (area of the square) - (area of the triangle)
Thus,
The area of the shadedregion is (area of the circle) - (area of the square) - (area of the triangle)

Answer:
10 minutes for the population to double.
Step-by-step explanation:
The general formula for the population equation, P(t), is:
We are given that for t =5 minutes and t = 2 minutes:
Solving for A and n:
The exponential equation that represents this situation is:
The population will double when P(t) = 512 bacteria:
To the nearest minute, it takes roughly 10 minutes for the population to double.

Answer:
Plant 2 grew faster
Step-by-step explanation:
The slope of plant 1 is 3
(each day the plant grew 3cm)
The slope of plant 2 is 5
(each day the plant grew 5cm)
The slope of plant 3 is 1.5
(each day the plant grew 1.5cm)
Mark can make 30 cakes in 5 days.
Given that Mark can make 42 birthday cakes in 7 days.
In 5 days Mark can make,
If the ratio can be 42 : 7
42/ 7 = x/ 5
where, x can be the number of cakes,
x = 30
So, 30 cakes can be done in 7 days.
