Here a=1, b= -5 and c= -3
so the discrim. is b^2 - 4(a)(c), or (-5)^2 - 4(1)(-3) = 25 + 12 = 37.
Because the discrim. is +, you'll have 2 real, unequal roots.
F(150) = 1500......(150,1500)
f(650) = 3900......(650,3900)
slope = (3900 - 1500) / (650 - 150) = 2400/500 = 24/5
y = mx + b
slope(m) = 24/5
(150,1500)...x = 150 and y = 1500
now sub and find b, the y int
1500 = 24/5(150) + b
1500 = 720 + b
1500 - 720 = b
780 = b
so ur equation is y = 24/5x + 780 or f(x) = 24/5x + 780 <==
or if u need it in standard form..
y = 24/5x + 780
-24/5x + y = 780....multiply by -5
24x - 5y = - 3900 <===
Answer:
G = Fr² / Mm
Step-by-step explanation:
Given:
F = GMm / r²
Where,
F = Force of the two objects
M = mass of object 1
m = mass of object 2
G = constant
r = distance between the objects
Solve the formula for G.
F = GMm / r²
Cross product
F * r² = GMm
Fr² = GMm
Divide both sides by Mm
G = Fr² / Mm
