Oliga [24]

Answer:

99.4 feet.

Step-by-step explanation:

You'd add 52.7 and 46.7, including 52.7 because she was already 52.7 feet under before she went even deeper.

Number 1 :

Answer: line A

Why: The slope is less steep therefore it would be easier to climb, compared to a steeper elevation like f.

A candy box is made from a piece of cardboard that measures 15 by 9 inches. Squares of equal size will be cut out of each corner

Valentin [98]

Answer:

1.82 inches

Step-by-step explanation:

Let the size of square piece cut from the corner is d.

So, the length of the box is 15 - 2y

width of the box is 9 - 2y

height of the box is d.

Volume of the box

Volume = length x width x height

V = (15 - 2y)(9 - 2y)y

V = 4y³ - 48y² + 135y

Differentiate with respect to y.

$\frac{dV}{dy}=12y^{2}-96y+135$

It is equal to zero for maxima and minima

$12y^{2}-96y+135=0$

$y=\frac{96\pm \sqrt{96^{2}-4\times 12\times 135}}{24}$

So, y = 1.82 in or 6.2 in

Now

$\frac{d^{2}{V}}{dy^{2}}=24y-96$

For y = 1.82 in, it is negative

and for y = 6.2 in, it is positive

So, the volume of the box is maximum if the height of the box is 1.82 inch.

Thus, the size of the square cut from each of the corner is 1.82 inches.
