Hello,

First we must use the property of the sum of perfect squares:

X^2 -14x +y^2 +10y+65 =0

Adding 7^2 and -7^2

x^2 -14x+7^2-7^2 +y^2+10y+65=0

x^2 -2.7x +7^2 -49 +y^2+10y+65=0

(X-7)^2 +y^2+10y+16=0

Adding 5^2 and -5^2

(X-7)^2 +y^2 +10y+5^2-5^2+16=0

(X-7)^2 +y^2+2.5y+5^2 -25 +16=0

(X-7)^2+ (y+5)^2 -9 = 0

(X-7)^2 +(y+5)^2 = 9

(X-7)^2+(y+5)^2 = 3^2

Center = (7, -5)
R = 3

The circle is in the 4 quadrant.

4. A loan made on March 12 is due September 10 of the following year. Find the exact time for the loan in a non-leap year and a
saul85 [17]

Answer:

182 days

Step-by-step explanation:

Given:

Date on which loan is made = March 12

Due date of the loan = September 10

Now,

The months in between March and September and the number of days in the particular months are

Month                          Number of days

April                               30

May                                31

June                               30

July                                 31

August                            31

------------------------------------------

Total number of days =  153

also,

Number of days left in March after 12 are (31 - 12 ) = 19 days

and,

Number of days in September before the due date = 10 days

Hence, the total time for loan = 19 + 153 + 10 = 182 days

since the included months does not have the month of February. Therefore,

the time for both leap year and non-leap year will remain same.

Answer:

I think its 4 because all the other ones are adding half of the original number

16-24 adds 8

8-12 adds 4

1-1.5 adds .5

so if it's going to 6 it should be 4 adding 2
