Answer:
36pi
Step-by-step explanation:
A=(pi)r^2
r^2=6*6 which is 36
so 36pi
Answer:
A = 1/2(y2-y1) (x3-x1)
A = 21 units^2
Step-by-step explanation:
The area of a triangle is 1/2 bh
Using the left side as the base b= 6 units
This is found by taking (y2-y1)
The height is 7 units, counting from the left side to x3
This is found by taking (x3-x1)
A = 1/2(y2-y1) (x3-x1)
A = 1/2 (6*7)
A = 1/2 *42
A = 21 units^2

The value of c such that the function f is a probability density function is 2
<h3>How to determine the value of c?</h3>
The density function is given as:
f(x) = cxe^(−x^2) if x ≥ 0
f(x) = 0 if x < 0.
We start by integrating the function f(x)
∫f(x) = 1
This gives
∫ cxe^(−x^2) = 1
Next, we integrate the function using a graphing calculator.
From the graphing calculator, we have:
c/2 * (0 + 1) = 1
Evaluate the sum
c/2 * 1 = 1
Evaluate the product
c/2 = 1
Multiply both sides of the equation by 2
c = 2
Hence, the value of c such that the function f is a probability density function is 2

3/6+1/6+1 2/3
Make 1 2/3 into an improper fraction:
5/3
Give them all common denominators by multiplying both sides of 5/3 by 2:
10/6
Then the question becomes:
3/6+1/6+10/6
Now you add the numerators and the denominator stays the same:
14/6
Now you can simplify by dividing both sides by 2:
7/3
Now you can make it a mixed number:
2 1/3
Hope this helps :)
