What are the center and radius of the circle with equation (−)+(−)=?Open x minus 4 close squared . Plus . Open y minus 9 close s

lbvjy [14]

Answer:

Center and radius of the circle of the equation ${(x - 4)^{2} + (y - 9)^{2} = 1$

center = ( 4,9) Radius = 1

Step-by-step explanation:

Given -

Equation of circle is $(x - 4)^{2} + (y - 9)^{2} = 1$

The equation of circle is represented by

$\boldsymbol{\mathbf{(x - a)^{2} + (y - b)^{2} = r^{2}}}$

where a and b are center of circle and radius r

Comparing these equation

then a = 4 and b = 9 and r = 1

In the Changing Dimensions of 3D Figures

den301095 [7]

Answer:factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is $S.A.=2(lw+wb+lb)$

Where l=length

w=width

b=breadth

So new length,breadth and width is

$l'=3l$

$w'=3w$

$b'=3b$

$S.A.=2(3\times 3lw+3\times 3wb+3\times 3lb)$

$S.A.=2\times 3^2(lw+wb+lb)$

$S.A.=3^2\times 2(lw+wb+lb)$

So new surface area would change by a factor of 9

What is the area?? Please help

Olegator [25]

Answer:

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

$A_{\triangle}=\dfrac{1}{2}bh$

b - base

h - height

The formula of an area of a rectangle:

$A_{\boxed{\ }}=lw$

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

$A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2$

$A_{\boxed{\ }}=(24)(10)=240\ ft^2$

The area of the figure:

$A=A_{\triangle}+A_{\boxed{\ }}$

Substitute:

$A=84+240=324\ ft^2$
