Mai wants to make an open top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard

Bumek [7]

Answer:

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

The domain for x is all real numbers greater than zero and less than 5 com

Step-by-step explanation:

<em><u>The question is</u></em>

What is the volume of the open top box as a function of the side length x in cm of the square cutouts?

see the attached figure to better understand the problem

Let

x -----> the side length in cm of the square cutouts

we know that

The volume of the open top box is

$V=LWH$

we have

$L=(10-2x)\ cm$

$W=(10-2x)\ cm$

$H=x)\ cm$

substitute

$V(x)=(10-2x)(10-2x)x\\\\V(x)=(100-40x+4x^{2})x\\\\V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

Find the domain for x

we know that

$(10-2x) > 0\\10> 2x\\ 5 > x\\x < 5\ cm$

The domain is the interval (0,5)

The domain is all real numbers greater than zero and less than 5 cm

therefore

The volume of the open top box as a function of the side length x in cm of the square cutouts is

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

What is the rate of return on a $5000 bond purchased at $4750 with a 12% coupon?

Mumz [18]

You earn 12% on the $5000 par value (face value) of the bond. So 0.12*5000 = 600 is the annual coupon payment. You earn $600 each year

This income is divided by the amount you paid to get

600/4750 = 0.1263 which converts to 12.63%

So the answer is choice 2) 12.63%

Genesis wants to ride her bicycle 31 miles this week. She has already ridden 7 miles. If she rides for 4 more days, write and so

tensa zangetsu [6.8K]

Since she has already ridden 7 miles out of 31 miles,

remaining miles to be ridden
= 31 - 7
= 24 miles

Let x be the number of miles she has to ride in each of the 4 days left.

4x = 24
x = 6
