Answer:

The least amount of dimensions would be using a 4ft x 4ft base.

Step-by-step explanation:

When looking to maximize area and minimize materials, a perfect square always does this. To prove the point, consider the 4 x 4 box in the answer to say a 16 x 1 box, which would have the same area.

The 4 x 4 box would have 4 sides each of 4 ft. Therefore, it would have 16 feet of sides to construct.

Meanwhile, there would be two sides on the other one that were 16 ft alone.

Which polynomial function has a leading coefficient of 1 and roots /7 and - /3 with multiplicity 1?
VladimirAG [237]

Answer:

  • A.  f(x) = (x - √2)(x + √3)

Step-by-step explanation:

Leading coefficient is 1, multiplicity is 1, roots are √2 and -√3. It means the function is the product of two binomials.

<u>The function with the roots of a and b is:</u>

  • f(x) = (x - a)(x - b)

<u>Substitute and and b:</u>

  • f(x) = (x - √2)(x - (-√3)) ⇒
  • f(x) = (x - √2)(x + √3)

Correct choice is A

3. Laura walks 3/5 mile to school each day. Isaiah walk to school is 3 times as long as Laura's. Howfar does Isaiah walk to scho
Finger [1]
Lets write down what we know...

Laura walks 3/5 mile to school everyday

Laura=3/5mile

Isaiah's walk is 3 times as long as Lauras, so

Isaiah=Laura*3

We know how far Lauras walk is so we can solve for Isaiah's walk

Isaiah=3/5*3 (or Isaiah=3/5+3/5+3/5 if thats easier for you to solve for)
Isaiah=9/5 miles

Now we know the answer! Great, Isaiah walks 9/5 miles to school each day. But 9/5 is an improper fraction, so lets convert it to a mixed number.

9/5=

To solve for this, we have to find out how many times 5 can go into 9. 5 goes into 9 one time with a remainder of 4, so we can write the mixed number as.

9/5= 1 4/5

Isaiah walks 9/5miles or 1 4/5 miles. Both are correct.
