What is the equation for the translation of X^2+y^2=9 four units to the right and three units down
icang [17]
We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)

the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²

see the attached figure

musickatia [10]

Answer:

y+2=-2(x-1)

Step-by-step explanation:

point-slope form

(y-y1)=m(x-x1)

m: slope = -2

(x1,y1) = (1,-2)

(y+2)=-2(x-1)

What is the area of this rectangle ? <br> Answer choices are in the picture
Lady bird [3.3K]

Answer:

D) 15x^8y^3

Step-by-step explanation:

Area = Length * Breadth

Area = 5x^6y^2*3x^2y

Apply exponent rule: a^b*a^c=a^{b+c}

Therefore,

Area = 5x^{6+2}y^2* \:3y

Area = 5x^8y^2*3y

Apply exponent rule as mentioned above:

Area = 5x^8y^{2+1}* \:3

Area = 5x^8y^3*3

Multiply 3:

15x^8y^3
