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

Making coconut cookies. The recipe calls for 420 g of coconut and 120 g of sugar. Only has 252 g of coconut. How much sugar must

geniusboy [140]

Answer: 72 grams.

Step-by-step explanation:

Let be "s" the amount of sugar in grams that must be used for 252 grams of coconut to keep the same ratio of coconut to sugar.

Knowing that in the recipe for the coconut cookies, should be 420 grams of coconut and 120 grams of sugar, and you only have 252 grams of coconut, you can set up this proportion to find "s":

$\frac{420grams}{120grams}=\frac{252grams}{s}$

Now, you need to solve for "s":

$\frac{420grams}{120grams}=\frac{252grams}{s}\\\\s(\frac{420grams}{120grams})=252grams\\\\s=(252grams)(\frac{120grams}{420grams})\\\\s=72grams$
