Hello :
<span>f(x) = (x – 1)(x + 6)
f(x) =0
</span>(x – 1)(x + 6) = 0
x-1=0 or x+6=0
x=1 or x= -6.....(answers : B and D)
The time of flight of a half projectile motion is given by V0 sin θ / g = 15(sin 45) / 9.8 = 1.08 seconds.
Answer:
Solve it
Step-by-step explanation:
When you're asked to simplify an expression it means to solve it.
16.5 degrees below the starting temp, whatever that is. If its 0, then -16.5 degrees.
The first equation would be (.5)5-11=-8.5, because the metal has been cooling for 5 hours.
The device that 'aids' in the cooling would be -5-3=-8, because it is a separate variable that cools the metal, so the amount the device cools is independent of the natural cooling amount, and the equation is independent of the natural cooling equation.
You then add -8.5 and -8, because the device has lowered 8.5 degrees and 8 degrees. This equals -16.5 degrees, or a decrease of 16.5 degrees.
