Answer:
The required equation in standard form is
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;
The given circle has center (-2,0) and radius squared can be calculated from the given area, which is
We substitute these values into the formula to obtain;
We simplify to get;
Given:
Ratio of cow to chicken is 6:5.
The nunmber of cows is 30.
The objective is to find the number of chickens.
Consider the number of cows and chicken as 6x and 5x.
The value of <em>x</em> can be calculated as,
Now, substitute the value of <em>x</em> to find the number of chicken.
Hence, the number of chicken will be 25.
Answer: 36/
Step-by-step explanation:
The k on top will cancel the k to the second power.
So the only number in the numerator is 1.
Then the 1 qill go away because you cant divide anything by 1.
The expoenet -2 that was at the top near K will become positive.
Then distribute
