Add 1.5 to both sides:

2\sin(x) = 1.83

Divide both sides by 2:

\sin(x) = 0.915

Consider the arcsin of both sides:

\arcsin(\sin(x)) = \arcsin(0.915)

Arcsin and sin simplify, because they are inverse of each other:

x = \arcsin(0.915)

Consider the sequence given by the formula a(n + 1) = 5a(n) and a(1) = 2 for n ≥ 1.
saw5 [17]

Answer:

The formula means; a of the next arithmetic n equals to 5 multiplied by a of the preceding n knowing that a of when n=1 is 2 and n must be 1 or greater than 1.

Step-by-step explanation:

a(n + 1) = 5* a(n)  for n≥1

given that

a(1) = 2

therefore:

when n = 1, a(2) = 5* a(1) = 5 * 2 = 10

when n = 2, a(3) = 5*a(2) = 5 * 10 = 50

The formula means; a of the next arithmetic n equals to 5 multiplied by a of the preceding n knowing that a of when n=1 is 2 and n must be 1 or greater than 1.

• Packaging of a product can cost a lot of money. Can you design
podryga [215]

The best arrangement can be

  • 3 rows and 4balls each row

So

  • Length of one row=1.8(4)=7.2cm
  • Width=1.8(3)=5.4cm
  • Height=1.8(2)=3.6cm

So

TSA

  • 2(LB+BH+LH)
  • 2(5.4(7.2)+(7.2)(3.6)+3.6(5.4))
  • 2(84.24)
  • 168.48cm²

Total cost

  • 168.48(0.01)
  • 1.685€
