Right triangles and trigonometry help!
Maslowich

Step-by-step explanation:

sin \: 45 \degree =  \frac{39}{z}  \\  \\  \therefore \:  \frac{1}{ \sqrt{2} }  =  \frac{39}{z}   \\  \\  \therefore \: z = 39 \sqrt{2}  \\ let \: p \: be \: the \: perpendicular \:  \\  \\\therefore \: tan \: 45 \degree =  \frac{39}{p}  \\  \\ \therefore \:1 = \frac{39}{p}  \\  \\ \therefore \:p = 39 \\  \\ sin \: 60 \degree =  \frac{39}{x}   \\  \\ \therefore \:  \frac{ \sqrt{3} }{2} =  \frac{39}{x}  \\  \\ \therefore \: x =  \frac{78}{ \sqrt{3} }  \\  \\ \therefore \: x =  \frac{78 \sqrt{3} }{ 3 }  \\  \\ \therefore \: x =  26 \sqrt{3} \\\\tan\: 60 \degree =  \frac{39}{y}   \\  \\ \therefore \:  \sqrt{3}  =  \frac{39}{y}  \\  \\ \therefore \: y =  \frac{39}{ \sqrt{3} }  \\  \\ \therefore \: y=  \frac{39 \sqrt{3} }{ 3 }  \\  \\ \therefore \: y =  13 \sqrt{3} \\

Graph the six terms of a finite sequence where a1 = −6.25 and r = 1.25.
Virty [35]

Answer:

Step-by-step explanation:

As per the question statement, a₁ is -6.25 and common ratio (r) is 1.25.

Therefore, the six terms of finite sequence would be as per the following equation f(n) = a1(r)^{n-1}. Thus, the series would be

  1. a1 = -6.25
  2. a2 = -6.25*r = -6.25*(1.25) = -7.8125
  3. a3 = -6.25*r^2 = -6.25*(1.25)^2 = -9.765625
  4. a4 = -6.25*r^3 = -6.25*(1.25)^3 = -12.20703125
  5. a5 = -6.25*r^4 = -6.25*(1.25)^4 = -15.2587890625
  6. a6 = -6.25*r^5 = -6.25*(1.25)^5 = -19.073486328125

So the points on the graph will be on following points,

(1, -6.25), (2, -7.8125), (3, -9.765625), (4, -12.20703125), (5, -15.2587890625), (6, -19.073486328125).

The graph would look like as attached.
