Answer:
Step-by-step explanation:
The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.
The ormua for calculating mid point is expressed as;
M(X,Y) ={(x21+x2/2, y1+y2/2}
X= x1+x2/2
Y = y1+y2/2
From the coordinates
x1 = 18 x2 = 4
X= 18+4/2
X = 22/2
X = 11
y1= -13, y2= -3
Y = -3-13/2
Y = -16/2
Y = -8
Hence the required centre will be at (11,-8)
<h3>Total cost of their lunch, including the tip is $ 27.6</h3>
<em><u>Solution:</u></em>
The cost for Dana and Courtney's lunch is $24
They want to leave a 15% tip
To find: total cost of their lunch, including the tip
<em><u>Find the tip amount</u></em>
Tip amount = 15 % of 24
<em><u>what is the total cost of their lunch, including the tip?</u></em>
Total cost = cost of lunch + tip amount
Total cost = 24 + 3.6
Total cost = 27.6
Thus total cost of their lunch, including the tip is $ 27.6
Answer:
V=4
/3 times pie(3.14) times r^3
Step-by-step explanation:
tany =2x+C is the required differential equation.
First we count how many hours is inbetween 8 and 3 which is 7
then subtract 10 for the first time
6:50 then add 45 for the second time
7:35
round down so she worked 7 1/2 hours
