Kobotan [32]

Answer:

156 different pairs will be there.

Step-by-step explanation:

As the order is  essential as we need different pairs therefore permutations will be used.

A permutation is any ordered subset of the objects r selected with regard to their order, from the set of  n distinct objects. It is given by nPr where n> r

Total number is 13 and required number is 2

n= 13 and r= 2

13 P2= 156 possible combinations.

A combination is any subset of the objects r selected without regard to their order, from the set of  n distinct objects. It is given by nCr where n> r

Find the y-coordinate of the y-intercept of the polynomial function defined
Bas_tet [7]
The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.

f(0) = 9(0)^2 - 7 - 8(0)

f(0) = -7

Therefore the “y” coordinate would be -7

The ordered pair would be

(0, -7)
