Answer:
3.625h,217.5min,13050sec
Step-by-step explanation:
S=vt
t=S/v
t=435/120 (km) /(km/h) =3.625h
t= 3.625*60 min = 217.5 min
t=217.5*60sec = 13050 sec
The y int is 8 and the slope is 1/2
Rectangle:
If each angles of a quadrilateral is 90 and opposite side are equal then it is a rectangle.
Rhombus:
If in a quadrilateral, opposite angles are equal and all sides are equal, then it is a Rhombus
Answer:
√10 / 10
Step-by-step explanation:
tan θ > 0 and sin θ < 0, so θ is in quadrant III. That means cos θ < 0.
cos(θ + π/4)
Use angle sum formula.
cos θ cos(π/4) − sin θ sin(π/4)
½√2 cos θ − ½√2 sin θ
Factor.
½√2 cos θ (1 − tan θ)
½√2 cos θ (1 − 2)
-½√2 cos θ
Write in terms of secant.
-½√2 / sec θ
Use Pythagorean identity (remember that cos θ < 0).
-½√2 / -√(1 + tan²θ)
-½√2 / -√(1 + 2²)
½√2 / √5
√10 / 10
