Answer:
110.1°
Step-by-step explanation:
Use the inverse cosine function (arccos or cos⁻¹).
... cos(θ) = -0.344
... θ = arccos(-0.344) = 110.1°
_____
The range of the arcos( ) function is 0 – 180°, so no adjustment of the angle is necessary. (Make sure your calculator is in <em>degrees</em> mode.)
Answer:
C
Step-by-step explanation:
1st year-> 30000
2nd year-> 31800
3rd year ->33708
4th year->35730.48
5th year -> 37874.3088
37874.3088+35730.48+33708+31800+30000= 169112.7888
≈ 169113

1: In order to organize and proritize the multiple tasks
2.
The order of the operation:
Simplified: multiplication, division, additon, substraction.
However you may confront brackets and exponents whic require another order.
Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x
