Answer:
E) 150°
Step-by-step explanation:
angle adjacent to 70° angle is 110°
the angle supplemental to 'x' must be 180-(40+110) or 30°
this means 'x' must be 150°
Answer:

Step-by-step explanation:
We are given that
Mass of crate=m=6.5 Kg
Height,
We have to find the magnitude of F when t=4 s
Differentiate w.r.t t

Again differentiate w.r.t t


Substitue t=4


Where 
Substitute the values



Y=3x2 3x(0.5)=1.5+2=3.5 Y=3.5
3(0.5)X2 1.5X2=3 Y=3
1.5/2=0.75 Y=0.75
1.5-2=-0.5 Y= -0.5
hope that helps . let me know plz
20000=1650e^(.5t)
12.121212=e^(.5t)
Ln(12.121212) = ln(e^(.5t))
2.49495 = .5t
4.98 = t
Rounding it will take approximately 5 years for the pop. to reach 20,000
63 = 10 + m
hope this helps :)
