Answer:
Answer: The total cost is assuming the cost for 1 adult is and the cost for 1 child is
Step-by-step explanation:
Ok
so the focus is on the opening side of the parabola
so for a vertex of (h,k)
opening up and down
(x-h)²=4p(y-k)
p is the distance from vertex to focus
it is also the distance from the vertex to the closes point on directix
2p=distance from focus to directix
p is positive if the focus is above the directix
ok
y=9 and (7,6)
9>6
directix is above the vertex
p is negative
find distance
from 9 to 6 is 3
3=2p
1.5=p
p is negative
and the vertex will be 1.5 above the focus and 1.5 below the directix
vertex is (7,7.5)
(x-7)²=4(-1.5)(y-7.5) is de equation
Step-by-step explanation:
1. 90+65= 155°
2. π+ π/6 = 7π/6 or 210°
3. 24+180=204°
4. 3π/2 + 2π/9 = (27π+4π)/18 = 31π/18
or 310°
<h3>Answer: Step-by-step explanation:
You have to make an addition with the individual times: 56.25+59.89+58.55+55.4=230.17 seconds. Now you should to convert it into a minutes and seconds. 1 minute= 60 seconds
2 minute= 120 seconds
3minute= 180 seconds
4minute= 240 seconds
In this way you they have 3 minutes and the remainder is 50 seconds.
So, the time for the team is 3 minutes and 50.17 seconds.</h3>
Answer:1.)6
2.) 12
Step-by-step explanation:
Vertices are points. There are 6 points. Edges are the lines. There are 12 lines
