We are given with two points of a parabola : v (5,-1) and f (3,-1). In this case, we can see that the parabola is opening to the left which means the standard form to be followed is -4a(x-h) = (y-k)^2. a is equal to 2. substituting, -4*2 (x-5) =(y+1)^2. This is equal to -8 (x-5) = (y+1)^2
Answer:
p=16
Step-by-step explanation:
8 pieces of fruit and 3 pears
means she bought 4 apples and 1 cantaluope
The height is 14 cm.
A=bh/2
42=6h/2
42(2/6)=h
(42÷6)x2=h
7x2=h
h=14
If we are drawing altitude from R the PQ will be base of this triangle. So we can say Median from R will cut on Midpoint of PQ. So firstly we will find mid point of PQ Which is S given as below:
P(4,-1) , Q (-2,7)
Let Co-ordinate of S is (x,y)
So
So midpoint of PQ is S(1,3).
Now we can find equation of RS
Co-ordinate of R is (9,9) and and S is (1,3).
In general equation of line from two point
and
is
So equation of RS is
So the equation of median is 6x - 8y = -66
