An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
Answer:
f(3/2)= 5√5
Step-by-step explanation:
f(3/2)= 5^(3/2)
f(3/2)= (5^3)^1/2 is the same things
f(3/2)= (125)^1/2 fraction exponent are the same are roots ^(1/2) is √
f(3/2)= √125
f(3/2)= √25 times √5 break up 125 to be 25 x 5
f(3/2)= 5√5 because √25 = 5 and √5 stays as √5
Answer:
64.8
Step-by-step explanation:
2040. 10 times 4 is 40. If it happens every ten years then when the Olympics happen 10 times it would be 2040.
Answer:
I think
11cm²-5cm²=121+25
and the square root of that will give you 12.08
and that's the answer
