Answer:
$0.84
Step-by-step explanation:
120.96/144= 0.84
Answer:
A) 2 units
Step-by-step explanation:
Given;
x² + y² - 4x - 4y + 4 = 0
Consider general circle equation;
(x - h)² + (y - k)² = r²
where;
(h , k ) is the center of the circle
r is the radius of the circle
x² + y² - 4x - 4y + 4 = 0
subtract 4 from both sides of the equation
x² + y² - 4x - 4y = - 4
square half of coefficient of x and y, and add them to both sides of the equation
x² + - 4x + (-2)² + y² - 4y + (-2)² = - 4 + (-2)² + (-2)²
factorize x and y
(x - 2)² + (y - 2)² = - 4 + 4 + 4
(x - 2)² + (y - 2)² = 4
(x - 2)² + (y - 2)² = 2²
Compare this final equation to general equation of a circle
(x - 2)² + (y - 2)² = 2²
(x - h)² + (y - k)² = r²
r = 2
Thus, the length of a radius of the circle is 2 units
Answer:
a) 2 people
b) 20 people
Step-by-step explanation:
a) The social network contains four people networking with six other people, altogether there are ten people netwoking together.
So, if one person in one social network, network with five others in the network, but when it is paired, we have eight altogether in the first case.
When the other case are paired, it is discovered that, the remaining pair is left with two people networking with three other people.
b) Altogether, when it is paired in each case, the following summation provides the number of people that network with each other:
First case = 1 + 5 + 2 = 8
Second case = 5 + 4 + 3 = 12
Altogether it is 20 people
160 or 90 students And also i think that this is the answer because it said that 35 percent of the students got a flu shot and it said if 125 students took a flu shot
