Answer:
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}
Step-by-step explanation:
(x-50)^2 is x^2+2500-100x*.0048 is .0048x. 2500*0.0048 is 12, and -100*0.0048=-.48.
So, we have .0048x^2+12-.48x+6, which is
.0048x^2+18-.48x=10. USing the quadratic formula, we get
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}

I THINK
We know that: sin Ф = cos(π/2 - Ф) ↔ sin Ф = cos(90° - Ф)
Then:
sin 42° = cos(90° - 42°) = cos 48°
IF sin 42° = 2/3, the cos 48° = 2/3
Answer:
-6/5 x 5/3 x 11
Step-by-step explanation:
the commutative property states that x * y = y * x where "x" is a number and "y" is also a number and also x+y=y+x. also "*" is the multiplication symbol
-6/5*11*5/3 can be re-arranged into 11*-6/5*5/3 you can cancel the numbers to get 11*-2/3*5=55*-2/3=-110/3
