Answer:
m∠ABC=42°
Step-by-step explanation:
m∠ABD=70°
⇒m∠ABD=m∠ABC+m∠CBD
⇒70°=(3x+33°)+(5x+13°)
70°=8x+46°
70°-46°=8x
24°=8x⇒x=3°
x=3°
Then,
m∠ABC=3x+33°
put x=3°, we get
m∠ABC=3×3°+33°=9°+33°
m∠ABC=42°
Answer:55.227
Step-by-step explanation:
Given data
mass =13lb
spring stretches by =4.5in=0.375 ft
g=
Now Spring constant K
mg=kx
k=
For critical damping
and
substituting values
c=55.227 lb.sec/ft
Answer:
Step-by-step explanation:
2/sin25=AB/sin90
AB=4.73
If n = the term number, then:
A(4) = 6-4(4-1)
A(4) = 6-4(3)
A(4) = 6-12
A(4) = -6
A = -1.5
it the temperature is -2 and rises by 15 you do -2+ 15 to get 13
