Answer:
And solving we got:
If we subtract 100 from both sides we got:
Step-by-step explanation:
For this case we have the following equation given:
We want to find a general expression given by:
Where the center is (h.k) and the radius is r.
We can begin completing the squares of the equation given and we got:
And solving we got:
If we subtract 100 from both sides we got:
Then we can conclude that the center is:
And the radius would be:
Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
She practices 5 hours a day.
120/4 = 30 hours per week.
30/6 = 5 hours per day.
To get 1% of $19.99 we can move the decimal place two spots to the left. This leaves us with .2 rounded. Then multiply .2 x 6 because its a 6% sales tax. This gives an answer of $1.2. The sales tax on the pair of jeans is an additional $1.20.
