Answer:

Well perimeter is adding up all the sides since it's a rectangle the first one is just 6 + 6 + 4 + 4 = 20 cm

The second would be 9 + 9 + 12 + 12 = 42 cm if this is not an option or if it is wrong let me know and I will try again

2. A square is graphed with the vertices at A(-5,-1)A(-5,-1), B(-2,3)B(-2,3), and
gladu [14]

Answer:

25 sq. units

Step-by-step explanation:

Because it is a square, you only have to find one if its side lengths. Let's say you choose to find the distance between B and C. You'll be finding the length of a hypotenuse due to the fact that the two points are diagonal from each other. Use the x and y values to discover the lengths of the legs of the triangle. In this instance, they are 3 and 4. Using background knowledge of the properties of triangles, I know that the hypotenuse of a right triangle with legs of 3 and 4 must be 5. Therefore, the side length of this square is 5. To find the area of a square, simply multiply its side length by itself. 5 x 5 = 25!

(_2/3)(Raised to power 3) multiplied by (_3/2)(raised to power 2)
Irina18 [472]

Answer:

\frac{-2}{3}

Step-by-step explanation:

From the given question,

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2}

Applying the required principle of indices to solve the question, we have;

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2} = \frac{(-2)^{3} }{3^{3} } x \frac{(-3)^{2} }{2^{2} }

= \frac{-8}{27} x \frac{9}{4}

= \frac{-72}{108}

= \frac{-2}{3}

Thus, the final answer is \frac{-2}{3}.

Q5: Identify the graph of the equation and write an equation of the translated or rotated graph in general form.
MAVERICK [17]

Answer:

d.\:ellipse;\:3x^2+y^2+6x-6y+3=0.

Step-by-step explanation:

The given conic has equation;

3x^2+y^2=9

Divide through by 9.

\Rightarrow \frac{3x^2}{9}+\frac{y^2}{9}=\frac{9}{9}

\Rightarrow \frac{x^2}{3}+\frac{y^2}{9}=1.

This is an ellipse centered at the origin;

This ellipse has been translated so that the center is now at;

(-1,3)

The translated ellipse has equation;

\frac{(x+1)^2}{3}+\frac{(y-3)^2}{9}=1.

Clear the fraction;

3(x+1)^2+(y-3)^2=9.

Expand;

3(x^2+2x+1)+(y^2-6y+9)=9.

3x^2+6x+3+y^2-6y+9=9.

Write in general form;

3x^2+y^2+6x-6y+9-9+3=0.

3x^2+y^2+6x-6y+3=0.

The correct choice is D
