You need four pieces in total.

In this type of problem, you add both numbers together. One side has one piece. The other has 3.

3+1=4

There are 4 total pieces needed.

The sum of the first number cubed and the second number is 500 and the product is a maximum.
soldier1979 [14.2K]

We are given the following information:

the sum of the first number cubed and the second number is 500

their product is a maximum

We are looking for the 2 missing numbers.

To answer this, let's represent the two numbers as x and w.

From the given, we can form the following equation:

x^3+w=500

We can then express y as:

w=500-x^3

We can express their product as:

x(500-x^3)=500x-x^4

To find the maximum value of x, let's solve for the derivative of -x^4 + 500 x.

\begin{gathered} f(x)=-x^4+500x \\ f^{\prime}(x)=-4x^3+500 \end{gathered}

Then we solve for the value of x where f'(x) = 0.

\begin{gathered} -4x^3+500=0 \\ -4x^3=-500 \\ x^3=125 \\ x=5 \end{gathered}

Then we use x = 5 to solve for the second number, w.

\begin{gathered} w=500-x^3 \\ w=500-5^3 \\ w=500-125 \\ w=375 \end{gathered}

Therefore, the two numbers are 5 and 375.

What’s the relationship between 0.04 and 0.004?
Rzqust [24]
0.04 Times .100 is 0.004. You’re just moving the 4 over a place value (from hundredths place to thousandths place). Notice that if you did 0.04 times 100 you would get 4. Essentially you’re just moving the 4 to different places and adding zeros.

69 degrees because since angle CBE is a straight line ir adds up to 180 degrees and hence you add the angles but since the triangle is isosceles angle AEB is also 69 degrees

A scatter plot and a possible line of best fit is shown:
Igoryamba

Answer: No, because the line does not touch any points.

Step-by-step explanation:

A line of best fit should pass through most if not all of the points on a graph. If it does not, it can't be considered a line of best fit.
