Answer:
y = (1/5)x² or y = x²/5
Step-by-step explanation:
We have the function f(x) = ax² and are given that the point (5,5) is on the parabola. We need to find 'a'. f(x) can be replaced with 'y', so we can rewrite the equation as...
y = ax²
We know that when x = 5, y = 5, so we have
5 = a(5²) now simplify...
5 = 25a
5/25 = a
1/5 = a, so our equation becomes
(1/5)x² or x²/5 (the expressions are equal)
Answer:
=6
Step-by-step explanation:
find the LCM of the two denominators 3 and 6 which is 6
equate in that such that 6÷3*2x=4x
6÷6×x=x
add the two=5x
5x/6=5
multiply by six both sides
5x=30
divide both sides by 5 to get x
x=6

Answer:
18.84cm
Step-by-step explanation:
There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3.
So 3x2x3.14=18.84cm
So then you could just multiply 6x3.14 and still get 18.84cm
Answer:
u = v2−2Egm−−−−−−−√
Step-by-step explanation:
2Eg = 2g (M2g(V2−U2)
2Eg = m(V2 - U2)
2Eg - mV2 - mU2
mU2 = mV2 - 2Eg
mU2m=mV2−2Egm
U2 = mV2−2Egm
= mV2m−2Egm
U2 = V2 - 2Egm
U = V2−2Egm−−−−−−−−√
