Answer with Step-by-step explanation:
We are given that
Compare with the equation of circle
Where center of circle=(h,k)
r=Radius of circle
a.Center of circle=(0,0)
Radius=
units
Center of second circle=(3,3)
Radius of second circle=
units
b.Distance formula:
Using the formula
The distance between the centers of two circle
=
Hence, the distance between the centers of two circle =
units.
c.
Substitute x=-1 and -1
The circle must be tangent because there is just one point (-1,-1) is common in both circles and satisfied the equations of circle.
Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17
Answer:
Eric,Tony,Jeff,Gary
Step-by-step explanation:
Given the payments made by each individual below:
- Tony paid 35% of the bill.
- Eric paid 3/8 of the bill.
- Jeff paid 0.175 of the bill
- Gary paid 1/10 of the bill.
The most convenient way to order their payments is to convert each to percentage.
Eric paid 3/8 of the bill.
- In Percentage:
Jeff paid 0.175 of the bill
- In percentage, 0.175 X100 =17.5%
Gary paid 1/10 of the bill.
In Percentage: 
Therefore, the order from most to least is:
Eric(37.5%), Tony(35%),Jeff(17.5%),Gary(10%)
Option B;
A suitable x-coefficient for a quadratic function that factors into a perfect square has to be even.
Answer:
There are two possibilities
a) If the integers are positives the product will be positive.
b) If the integers are negatives the product will be negative.
Step-by-step explanation:
We need to use rule of signs to explain the answers
for answer "a"
We have (+)(+)( + ) equals positive
for answer "b"
We have (-)(-) = + then this multiply by the last integer which has negative sign
(+)(-) = -
