Find the solutions of each equation on the interval [0, 2π)

Schach [20]

Answer/Step-by-step explanation:

Factor this. GCF=2

2(2cos2x+cos x-1)=0

2(2cos x -1)(cos x+1)=0 Set each factor equal to zero and solve

2cos x -1=0 Add 1 to both sides

2cos x =1 Divide by 2

cos x =1/2

x=π/3

x=5π/3

cos x+1=0 Subtract 1 from both sides

cos x=-1

x = π

Can someone tell me how do I solve this. how is the result 2.40

liubo4ka [24]

Step-by-step explanation:

Properties used

logₐ a = 1
log aᵇ = b log a
log ab = log a + log b

See the steps below

- log (4*10⁻³) =
- (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- (0.6 - 3*log 10) =
- (0.6 - 3*1) =
- (0.6 - 3) =
- (- 2.4) =
2.4

Simplify

ivolga24 [154]

The correct answer is: [A]: " $\frac{8}{729}$ " .
_________________________________________________________
Explanation:
_________________________________________________________
We are asked to simplify:

  → $(\frac{2}{9})^3$

_________________________________________________________
Note the following property of exponents:
_________________________________________________________

$( \frac{a}{b})^n$   = $\frac{(a^n)}{(b^n)}$ ; { b $\neq$ 0 } .

_________________________________________________________
As such:

→ $( \frac{2}{9})^3$ ;

= $\frac{2^3}{9^3}$ = $\frac{(2*2*2)}{(9*9*9)}$ = $\frac{8}{729}$ .

_____________________________________________________________

The answer is: " $\frac{8}{729}$ " ;

→ which is: "Answer choice: [A]:  " $\frac{8}{729}$ " .
_____________________________________________________________
Hope this answer—and explanation—is of some help to you.

An installation technician for a specialized communication system is dispatched to a city only when 3 or more orders have been p

bazaltina [42]

Answer:

0.3233

0.09

Step-by-step explanation:

Given that :

Mean, λ = 0.25 for a 100,000 per week

For a population of 800,000 :

λ = 800,000 / 100,000 * 0.25 = 8 * 0.25 = 2 orders per week

Probability that technician is required after one week ;

After one week, order is beyond 2 ; hence, order, x ≥ 3

P(x ≥ 3) = 1 - [p(x=0) + p(x= 1) + p(x =2)]

P(x ≥ 3) = 1 - e^-λ(1 + 2¹/1! + 2²/2!)

P(x ≥ 3) = 1 - e^-2(1+2+2) = 1 - e^-2*5 = 1 - e^-10

P(x ≥ 3) = 1 - e^-2 * 10

P(x ≥ 3) = 1 - 0.6766764

P(x ≥ 3) = 0.3233

B.)

Mean, λ for more than 2 weeks = 2 * 2 = 4

P(x < 2) = p(x = 0) + p(x = 1)

P(x < 2) = e^-4(0 + 4^1/1!)

P(x < 2) = e^-4(0 + 4) = e^-4(5)

P(x < 2) = e^-4(5) = 0.0183156 * 5 = 0.0915

P(x < 2) = 0.09
