4n ≥ 5/6
Step-by-step explanation:
Hope this helps!!!
221,450,000. move the decimal until there is only one number to the left
it moves 8 places
2.2145 * 10^8
2*10^8
Choice C
We make a drawing to find the relationship between the angle and the sides
given
dh/dt=4m/sec
we get
tan(x)=h/40
where x is the angle and h is the height
take the derivitive of both sides
1/cos²(x)(x)dx/dt=
1/cos²(x)dx/dt=
1/cos²(x)dx/dt=
solve for dx/dt
times both sides by cos²(x)
dx/dt=
remember that dh/dt=4
also, solve for the angle at that time
h=40 and base=40 so x=45 degrees (pi/4 radians)
input that
dx/dt=
dx/dt=
dx/dt=0.05
A is the answer
Answer:
36
Step-by-step explanation:
When negative gets squared, it becomes positive
