Answer:
16.25
Step-by-step explanation:
If you multiply 16.25 by 8 you get 130 then if you multiply 130 by 20 for each day worked you get 2600
The correct question is
<span>What is the equation in standard form of an ellipse centered at the origin and vertex (4,0) and focus (1,0)
</span>
we know that
<span>Standard form of equation for an ellipse with horizontal major axis is
(x-h)</span>²/a²+(y-k)²/b²=1
the center is the origin
so
(h,k) is (0,0)<span>length of horizontal major axis------> 8=2a-----> a=4
a</span>²=16
c=1 (distance from center to focal point)
c²=1
b²=a²-c²-----> b²=16-1----> b²=15
the equation is
(x)²/16+(y)²/15=1
the answer is
(x)²/16+(y)²/15=1
Answer:
same
Step-by-step explanation:
The question is asking how many combinations of two people can be made from a group of ten people.
Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.
A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
