Find three consecutive numbers whose sum is 612

Answers

Answer 1
Answer:

Answer: 203, 204, 205

Step-by-step explanation:

Consecutive numbers are numbers that are right next to each other. An example would be 1,2,3 or 67,68,69. Since this problem is asking for three consecutive numbers where the sum is equal to 612, we need to find the numbers that will be greater than 200.

Since we know that the sum is 612, we know that the numbers will be in the 2 hundreds. All we need to do is find 3 numbers that equal to 12.

3+4+5=12

Now that we have the three numbers, let's add 200.

203+204+205=612

Therefore, the three numbers are 203, 204, 205.

Answer 2
Answer:

Answer: 203, 204, 205

Step-by-step explanation:

Let's say the number is x.

So the three consecutive numbers are: x, x + 1, and x+ 2

3x + 3 = 612

3x = 609

x = 203

Plug in x.

203, 204, and 205

Find the Derivative.
f(x) = -xcos3x

Answers

Answer:

(d)/(dx)(-xcos3x)=  3x \ sin(3x)- cos(3x)

Step-by-step explanation:

Use the Product Rule for derivatives, which states that:

  • (d)/(dx) =[f(x)g(x)]= f(x)g'(x)+f'(x)g(x)

In the function we are given, f(x)=-x \cos3x, we can break it up into two factors: -x is being multiplied by cos3x.

Now, we have the factors:

  • -x \n   $cos 3x

Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.

  • (d)/(dx)(cos3x)= (d)/(dx) (cos3x) * (d)/(dx) (3x) \n (d)/(dx)(cos3x)= (-sin3x) * 3 \n (d)/(dx) (cos3x) = -3sin(3x)

Now let's apply the product rule to f(x) = -xcos3x.

  • (d)/(dx)(-xcos3x)=  (-x)(-3sin3x) + (-1)(cos3x)

Simplify this equation.

  • (d)/(dx)(-xcos3x)=  (x)(3sin3x) - (cos3x)

Multiply x and 3 together and remove the parentheses.

  • (d)/(dx)(-xcos3x)=  3x \ sin(3x)- cos(3x)

Therefore, this is the derivative of the function f(x)=-xcos3x.

Hi there!

\large\boxed{f'(x) =  -cos3x + 3xsin3x}

f(x) = -xcox3x\n\n\text{Use the product rule and chain rule to solve for the derivative:}\n\n(dy)/(dx)= -cos3x + (-x * (-sin3x) * 3)\n\n= -cos3x + 3xsin3x
