Answer:
(fg)(x) = (4x^2 + x^4)(x^2 + 4)^(1/2)
Step-by-step explanation:
Mathematically;
(fg)(x) = f(x) * g(x)
so we have;
4x^2 +x^4 * √(x^2 + 4)
But √(x^2 + 4) = (x^2 + 4)^(1/2)
So we have;
(fg)(x) = (4x^2 + x^4)(x^2 + 4)^(1/2)
Answer:
I really dont know
Step-by-step explanation:
Answer:
Yes, C is the correct answer
Step-by-step explanation:
Just look where the red arrow starts and where the blue arrows ends
The answer is 0.45
------------------------------------
Work Shown:
P(B|A) = P(B and A)/P(A)
0.2 = P(B and A)/0.9
0.2*0.9 = P(B and A)
0.18 = P(B and A)
P(B and A) = 0.18
P(A and B) = 0.18
P(A|B) = P(A and B)/P(B)
P(A|B) = 0.18/0.4
P(A|B) = 0.45
Answer:

Step-by-step explanation:
To solve a formula for one of its variables do that
- Separate it on one side and the other terms on the other side
- Make its coefficient equals 1
Let us use these steps to solve our question
∵ V =
b²h
→ Underline b
∴ V =
<u>b²</u>h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = <u>b²</u>h
→ Divide both sides by h to move it to the other side
∴ 
→ To find b take √ for both sides
∴ 
→ The square root will cancel the power 2 of b
∴ 
→ Switch the two sides
∴
