Answer:
as discriminant = 9, it has two real solutions.
Step-by-step explanation:
for eqn ax^2 + bx + c, discriminant = b^2 - 4ac
y = 4x^2 - 5x + 1
discriminant = (-5)^2 - 4(4)(1)
= 25 - 16
= 9
as discriminant > 0, it has two real solutions.
Answer below. hope it’s right !
Answer:
1872
Step-by-step explanation:
Plug is 16 for x
f(x)=13(4−x)^2
f(16)=13(4−16)^2
f(16)=13(-12)^2
-12^2=144
f(16)=13(144)
f(16)=1872

Answer:
3 3/8
Step-by-step explanation:
y×(2/3)=2.25 (the same as 2 1/4)
÷2/3. ÷2/3
y=3.375
3 3=8 gallons
more of break down:
y×2/3=9/4
÷2/3 or ×3/2
y= 9. 3. 27
--- × ---- = ----- = 3 3/8

Answer:
±sqrt(E/m)= c
Step-by-step explanation:
E=mc^2
Divide each side by m
E/m=m/m c^2
E/m =c^2
Take the square root of each side
±sqrt(E/m)= sqrt(c^2)
±sqrt(E/m)= c
