Answer:
θ = 2π/3 or 5π/3
Step-by-step explanation:
2 cosθ + 1= 0
when + 1 goes to R H S Side than it becomes negative by transposition method
2 cos = -1
now by dividing by 2 both sides we get
cosθ = -
since cosθ is negative
Cosθ = - cos 60°
it means either cosθ lies in 2nd or third quadrant
θ = π - π/3
or
θ = 2π- π/3
so θ = 2π/3 or 5π/3
Answer is 7.
55+5X=90
5X=90-55
5X=35
X=35/5
X=7
Answer:
Number of fruit flies after 14 days is equal to 1880.
Step-by-step explanation:
given,
fruit flies at the beginning of the experiment = 200 fruit flies
rate of increase of fruit flies = 5 per hour
to calculate the number of flies after 14 days.
time = 14 days = 14 × 24 = 336 hours
flies after 14 days = initial number of flies + rate of increase × time
= 200 + 5 × 336
= 1880 fruit flies.
hence,Number of fruit flies after 14 days is equal to 1880.
