What is the center and radius of -10x = -121 - y2 - x2 -22y
OlgaM077 [116]

We need to find the center and the radius of

-10x\: =\: -121\: -\: y^2\: -\: x^2\: -22y

The general circle equation is the following

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center and

r is the radius

1. rearrange the equation

(x^2-10x)+(y^2+22y+121)=0

2. Add 25 on both sides

(x^2-10x+25)+(y^2+22y+121)=25

3. Factor

(x-5)^2+(y+11)^2=5^2

Now we have an equation that is very similar to the circle equation, so let's compare them

Center -> (h,k) = (5,-11)

radius -> r = 5

Paisley has 8\tfrac{1}{4}8 4 1 ​ cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 ​ cup of yogurt. How
Ivenika [448]

Given:

Total Yogurt = 8\dfrac{1}{4} cups

Yogurt required for each smoothie = \dfrac{11}{16} cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}

Substituting the given values, we get

\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}

\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=3\times 4

\text{Number of smoothies}=12

Therefore, the number of smoothies is 12.
