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

Answer:
a2+2a−8
Step-by-step explanation:
Expand (a+4)(a−2)(a+4)(a-2) using the FOIL Method.
a⋅a+a⋅−2+4a+4⋅−2
The answer is 12. 1 orange can feed 2 kids so 1 orange=2 kids, 2 oranges=4 kids so on and so on then you get to 12 oranges=24 kids. hope this helps
