Answer:
The equivalent fraction would be 4/5, in decimal .80
Step-by-step explanation:
Use the Cosine Rule:-
AC^2 = 6^2 + 8^2 - 2*6*8 cos 78
= 80.04
So AC = sqrt 80.04 = 8.9 to nearest tenth
Answer:
Constant of Proportionality is 50.
Step-by-step explanation:
Albatross can fly 400 kilometers in 8 hours.
'd' represents the distance and 't' represents the number of hours.
The equation 
represents the relationship between the distance and time.
Now, in the equation shown above 50 is the constant of proportionality, and 50 represents the rate of change of distance with time.
The constant of proportionality tells us the rate of change between two variables.
So for every 1 hour of time the distance covered is 50 kilometers.
Yay
so
this is going to be
(x-h)^2=4p(y-k)
(h,k) is the vertex
p is the distance from the vertex to the focus and the vertex to directix
half of the distance between directix and focus is p
if the directix is above the focus, p is negative
if the directix is below the focus, p is positive
so
we see
y=15/8 is the directix
focus is above directix (p is positive)
it is 2/8 or 1/4 above it
so
half of 1/4 is 1/8
p=1/8
the vertex is 1/8 below vertex so it is it at (-4,16/8) or (-4,2)
the equation is
(x-(-4))^2=4(1/8)(y-2) or
(x+4)^2=4(1/8)(y-2) is the equation
Answer:
x>-4/3 last answer i got i hope it is helpful have a nice day
