Answer:
vertex
Step-by-step explanation:
vertex
If the coefficient a > 0, then the parabola opens upward and the vertex is the lowest point on the parabola. We say that k is the minimum value of the quadratic function. On the other hand, if the coefficient a < 0, then the parabola opens downward and the vertex is the highest point on the parabola.
Given :
.
.
To Find :
The general equation of 
.
Solution :
We know , when difference between any two consecutive terms in an A.P is equal , then the series is in arithmetic progression .
Now , common difference ,
Also , first term is -25 .
Now , general term of an A.P is given by :
Hence , this is the required solution .
Answer:
Step-by-step explanation:
c + 6 < -20
Subtract 6 from both side
c +6 -6 < -20-6
c < -26
So value of c should be less than -26. Value of c = { - ∞ ...... -28, - 27 }
Eg:
If c = -27
-27 + 6 = - 21 . -21 is less than -20
The park charges 1.50 per ride.
1. Louisa bought 15 ride tickets at 1.50 each.
Equation: C = Entry Fee + 1.50t
t = 15.
c = 30.75
30.75 = Entry Fee + 1.50(15)
30.75 = Entry fee + 22.50
Entry fee = 30.75 - 22.50
Entry fee = $8.25
2. Entry fee was calculated as 8.25 from #1.
Tickets are 1.50 each.
He can spend 22.
22 = 8.25 + 1.50t
Subtract 8.25 from both sides:
13.75 = 1.50t
Divide both sides by 1.50:
t = 13.75 / 1.50
t = 9.2
He can buy 9 tickets.
Answer: 168 rupees.
Step-by-step explanation:
sure thing! first, i divided 378 by 9, so that i could find the cost of ONE meter of cloth.
378/9 = 42
then, i just multiplied 42 by 4, in order to find the total cost for 4 meters.
42 x 4 = 168
