Answer:

The graph of image and preimgae is shown below.

Step-by-step explanation:

From the given figure it is noticed that the vertices are A(-2,2), B(5,2), C(5,0), D(0,0), F(0,-2) and G(-2,-2).

It is given that figure ABCDFG is rotated by positive 90° about the origin (0,0).

Positive means counter clockwise and negative means clockwise.

If a figure is rotated by counter clockwise 90° about the origin (0,0), then

(x,y)\rightarrow (-y,x)

The vertices of image are

A(-2,2)\rightarrow A'(-2,-2)

B(5,2)\rightarrow B'(-2,5)

C(5,0)\rightarrow C'(0,5)

D(0,0)\rightarrow D'(0,0)

F(0,-2)\rightarrow F'(2,0)

G(-2,-2)\rightarrow (2,-2)

The graph of image and preimgae is shown below.

Jeans are reduced from 28.00 to 18.20 during a sale at a department store. What percentage was the original price reduced?
Natali [406]

Answer:

The original price was reduced 35%

Step-by-step explanation:

we know that

Jeans are reduced from $28.00 to $18.20

In this problem

The original price of 28.00 represent 100%

so

using proportion

Find out what percentage represent the difference between the original price and the new price

\frac{28}{100}=\frac{28-18.20}{x}\\\\x=100(9.8)/28\\\\x=35\%

therefore

The original price was reduced 35%

Find the dimensions of the rectangular box with largest volume if the total surface area is given as 64cm^2
motikmotik
Let x =lenght, y = width, and z =height 
<span>The volume of the box is equal to V = xyz </span>
<span>Subject to the surface area </span>
<span>S = 2xy + 2xz + 2yz = 64 </span>
<span>= 2(xy + xz + yz) </span>
<span>= 2[xy + x(64/xy) + y(64/xy)] </span>
<span>S(x,y)= 2(xy + 64/y + 64/x) </span>
<span>Then </span>
<span>Mx(x, y) = y = 64/x^2 </span>
<span>My(x, y) = x = 64/y^2 </span>
<span>y^2 = 64/x </span>
<span>(64/x^2)^2 = 64 </span>
<span>4096/x^4 = 64/x </span>
<span>x^3 = 4096/64 </span>
<span>x^3 = 64 </span>
<span>x = 4 </span>
<span>y = 64/x^2 </span>
<span>y = 4 </span>
<span>z= 64/yx </span>
<span>z= 64/16 </span>
<span>z = 4 </span>

<span>Therefor the dimensions are cube 4.</span>
