Answer:

-\frac{41}{65}

Step-by-step explanation:

In order to find the answer to this question remember to use KCC (Keep, Change, Change) and find the least common denominator. (LCD)

-\frac{3}{13}-\frac{2}{5}

Use KCC

-\frac{3}{13} +-\frac{2}{5}

Now add

LCD=65

\frac{-3\times5}{13\times5} -\frac{2\times13}{5\times13}

=\frac{-15-26}{65}

=-\frac{41}{65}

Hope this helps.

An open-top rectangular box with square base is to be made from 100 square feet of material, as shown.
-Dominant- [34]

The largest possible volume of the given box is; 96.28 ft³

<h3>How to maximize volume of a box?</h3>

Let b be the length and the width of the base (length and width are the same since the base is square).

Let h be the height of the box.

The surface area of the box is;

S = b² + 4bh

We are given S = 100 ft². Thus;

b² + 4bh = 100

h = (100 - b²)/4b

Volume of the box in terms of b will be;

V(b) = b²h = b² * (100 - b²)/4b

V(b) = 25b - b³/4

The volume is maximum when dV/db = 0. Thus;

dV/db = 25 - 3b²/4

25 - 3b²/4 = 0

√(100/3) = b

b = 5.77 ft

Thus;

h = (100 - (√(100/3)²)/4(5.77)

h = 2.8885 ft

Thus;

Largest volume = [√(100/3)]² * 2.8885

Largest Volume = 96.28 ft³

I just need someone to explain how to do it
Mashutka [201]
You just need to substitute the the given function. So if f(-8) then you fill in f(n)=2n+4 which would be f(-8)=2(-8)+4. Which is -12.

hope this helps !

What are the coordinates of the midpoint of the segment whose endpoints are (-4,6) and (-8,-2)
umka2103 [35]
The formula to find the midpoint of a segment is ((x1 + x2)/2,),(y1 + y2)/2).

The x coordinate of the first point is -4, and the x coordinate of the second point is -8.  The y coordinate of the first point is 6, and the y coordinate of the second point is -2.  Now, we can plug these into our formula.

((-4 + (-8))/2), (6 + (-2))/2)) = (-12/2), (4/2) = (-6, 2)

So, (-6, 2) is the midpoint of the segment.

Okay, all we need to do is divide 8 from both sides:

-104/8=-13

So x=-13
