2 bc cos A
Step-by-step explanation:
Cosine rule
Answer:
option 3: 3(10+5) = 30+15
Step-by-step explanation:
The coordinates of the vertex are (h,k) so we can write:-
f(x) = a(x -2)^2 - 4
now when f(x) = -7 x = 1 so:-
-7 = a(1-2)^2 - 4
-7 = a - 4
a = -3
so the vertex formula is
f(x) = -3(x - 2)^2 - 4
standard form:-
f(x) = -3(x^2 - 4x + 4) - 4
= -3x^2 + 12x - 16
A number that is 2 more than the other but the smaller one is not even
example
9 divided by 7 or 18 divided by 7
