I cant see all the question but this is how you find the derivative of your function using the product rule.
Here you use the extension of the product rule to 3 factors which we'll write as:-
f(x), g(x) and h(x):-
Derivative = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
(3x - 1)(x + 4)(2x - 1)
derivative = 3(x + 4)(2x - 1) + (3x + 1)(1)(2x - 1) + (3x - 1)(x + 4)(2)
= 3(x + 4)(2x - 1) + (3x + 1)(2x - 1) + 2(3x - 1)(x + 4)
This question is incomplete. Hereis the complete question:
Which of the following options have the same value as 65% of 20?
(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20
Answer:
The correct answer is option (A) 0.65⋅20
Step-by-step explanation:
In this case they are asking us for an expression that is equivalent to 65% of 20. They are not asking us what is the value of that operation.
When we do a percentage calculation we can do it in two ways.
Let's see each one of them:
. (65 * 20): 100 =
1300: 100 = 13
. 0.65. 20 = 13
As we can see both ways we get the same result.
Given this information we can say that the correct answer is option A.
Answer:
13
Step-by-step explanation:
You find out what is one percent then multiply from there
Answer: 28cm^2
Step-by-step explanation: Split the trapezoid into three parts. A square 4x4, and two triangles 3x4. The square is 14cm^2 the two triangles are (3x4) / 2 x2 (3 times 4 divided by 2 times 2, or just 3x4)
