because
the pattern is
(5 10) ..1.. (15 20) ..2.. (25 30) ..3..


..1... = 3
..2.. = 13
so ..3.. = 23

Answer:

23

Step-by-step explanation:

The given series of numbers is 5 10 3 15 20 13 25 30 _

Segregating the numbers in sets of 3 we have:

5 10 3

15 20 13

25 30 _

The difference between 2 corresponding terms in adjacent sets is 10.

For example: taking the first terms from each set,it is 5, 15 , 25

Similarly taking the second term from each set, it is 10,20,30

Hence, taking the third term: 3, 13, 23.

So the missing term in the sequence is 23.

An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p
True [87]

Answer:

the value of a, if points A and D belong to the x−axis and m∠BAD=60 degrees is 2/√3

Step-by-step explanation:

Trapezoid ABCD with height 2 unit contain Points A and D which may be A(-1,0) and D(5.0)

Vertex of parabola is the point where parabola crosses its axis

Let suppose A and D are two points then draw altitude on them CE where C is on AD

As height of altitude has been given that is 2 then

total angle = 180 degrees

m∠BAD=60 degrees

m∠CEA =180 - 60 -90

             = 30

then the value for  AE = 2/√3.

y=a(x+1)(x−5).

where  2/√3 is right of -1 and 2 unit above x-axis
