A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,

Svetradugi [14.3K]

Answer:

The quadratic equation that best models the volume of the box (in terms of W) is:

$70W-5W^2$

Step-by-step explanation:

The perimeter of the rectangular base = 28cm

Perimeter of a rectangle = 2(L+W)

2(L+W)=28

L+W=14

L=14-W

Volume of the Box= LWH

Since L=14-W and Height Of the Box= 5cm

Volume of the Box= (14-W)W X 5

$=5(14W-W^2)\\ =70W-5W^2$

Change the expression to a single square root, or its opposite:

aleksley [76]

Answer:

a) $2\sqrt{2}=\sqrt{8}$

b) $-7\sqrt{3} =-\sqrt{147}$

c) $\frac{1}{3} \sqrt{18b} =\sqrt{2.b}$

d) $5\sqrt{y} =\sqrt{25y}$

e) $-6\sqrt{2a} =-\sqrt{72a}$

f) $-0.1\sqrt{200c}=- \sqrt{2c$

Step-by-step explanation:

a) $2\sqrt{2}=( \sqrt{2} )^2.\sqrt{2}=(\sqrt{2})^3 = \sqrt{2^3} =\sqrt{8}$

b) $-7\sqrt{3} =-(\sqrt{7} )^2\sqrt{3} =-\sqrt{7^2.3} =-\sqrt{147}$

c) $\frac{1}{3} \sqrt{18b} =\frac{1}{3} \sqrt{9.2.b} =\frac{1}{3} \sqrt{3^2.2.b} =\frac{1}{3} \times 3\sqrt{2.b} =\sqrt{2.b}$

d) $5\sqrt{y} =\sqrt{5^2} \sqrt{y}=\sqrt{25y}$

e) $-6\sqrt{2a} =-\sqrt{6^2}\sqrt{2a} = -\sqrt{36.2a} =-\sqrt{72a}$

f) $-0.1\sqrt{200c}=-\frac{1}{10} \sqrt{10^2.2c} =-\frac{1}{10}\times10 \sqrt{2c}=- \sqrt{2c$

aniked [119]

Answer:

-0.43

Step-by-step explanation:

Mean is calculated by adding all the number and dividing them by the total amount of numbers.

6+(-10)+6+(-6)+5+4+(-8)= -3‬

Now we have the sum

There are a total of 7 numbers

-3/7=-0.42857142857142857142857142857143

rounded is -0.43
