Answer:
Therefore the required Equation of Circle
Step-by-step explanation:
Given:
End point of Diameter be
point A( x₁ , y₁) ≡ ( -2 ,-2 )
point B( x₂ , y₂) ≡ ( 4 , -10 )
To Find:
Equation of a circle =?
Solution:
When end points of the Diameter are A( x₁ , y₁) , B( x₂ , y₂). then the Equation of Circle is given as
Substituting the end point are
Applying Distributive Property we get
Therefore the required Equation of Circle
The price of a baseball is $3.75. This problem can be solved using an elimination between two equation with two variables in it which are, 5x + 3y = 23.75 and 2x + 7y = 31.25. First, multiply the first equation by 2 and the second equation by 5 which resulting in 10x + 6y = 47.5 and 10x + 35y= 156.25 and then eliminate the x variable resulting in 29y = 108.75. The baseball price can be acquired from this equation (y = 3.75) because y variable represents the baseball price.
Answer:
The answer is 8.24%.
Step-by-step explanation:
The rate r = 8% is for 1 year or 52 weeks.
As given there are 13 weeks term so total there will be = 4 terms.
So, n = 4
The effective interest rate R is given by:
R = 
= 
= 
= 0.0824
And in percentage, it is 8.24%.
Answer:
The final price is $361.25
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 425 × 15/100
Discount = 425 x 0.15
You save = $63.75
Final Price = Original Price - Discount
Final Price = 425 - 63.75
Final Price = $361.25
