Answer:
√5/3.
Step-by-step explanation:
Using the identity sin^2 O + cos^ O = 1
sin^2 O = 1 - cos^2 O
sin^2 O = 1 - (2/3)^2
sin^2 O = 1 - 4/9
sin^2 O = 5/9
sin O = √(5/9)
sin O = √5/3.
Answer:
t = 1.068 s
Step-by-step explanation:
given,
a(t) =- k v(t)
speed of the object decreases from 800 ft/s to 700 ft/s
distance = 1400 ft
time for deceleration = ?
a(t) =- k v(t)
integrating both side
..........(1)
since,
from equation 1
putting value of k in equation (1)
t = 1.068 s
Answer:
X INTERCEPT = -0.5
Step-by-step explanation:
To find the X intercept you simply replace the Y with a zero.
this would make it 0=4x+2
now you solve it as usual.
0=4x+2
-2=4x
-2/4=4x/4
-0.5=x
x=-0.5
1. Side PQ, side QR, side PR
2. Angle M, angle S, angle N
3. x<25
