Answer:
x=4,-4
Step-by-step explanation:
|x| > 10
x < - 10 or x > 10
The plot is open dots on -10 and 10 and shading to the left of -10 and to the right of 10.
Answer is the third choice.
One of the angles of a right triangle is always 90 degrees. we have another 13.7 degrees angle. so we can find the other acute angle
the other acute angle measures 76.3
Answer:
df(t)/dt = 10 - 0.8f(t)
Step-by-step explanation:
The net rate of change, df(t)/dt = rate in - rate out
The rate in = rate litter forms on ground = 10 g/cm²/yr
Since f(t) is the amount of litter present at time, t, in g/cm² the rate out = rate of decomposition = the percentage rate × f(t) = 80% per year × f(t) = 0.8f(t) g/cm²/yr
Since df(t)/dt = rate in - rate out
df(t)/dt = 10 - 0.8f(t)
So the desired differential equation is
df(t)/dt = 10 - 0.8f(t)
F(3) = (<span>√3 -7)/6
f(3) = (1.732 - 7)/6
f(3) = 5.268 / 6
f(3) = 0.878 ...nearest thousandths
