Consider the sequence 10, 2..
romanna [79]

Answer:  see below

<u>Step-by-step explanation:</u>

1) 10, 2, 1.2, 1.12, 1.112, 1.1112

t_n=\dfrac{t_{n-1}}{10}+1

t₁ = 10

t₂ = 10/10 + 1    = 2

t₃ = 2/10 + 1     = 1.2

t₄ = 1.2/10 + 1   = 1.12

t₅ = 1.12/10 + 1  = 1.112

t₆ = 1.112/10 + 1 = 1.1112

2)  10, 2, -2, -4, -5, -5.5, ...

t_n=\dfrac{t_{n-1}}{2}-3

t₁ = 10

t₂ = 10/2 - 3 =   2

t₃ = 2/2 - 3  =  -2

t₄ = -2/2 - 3 =  -4

t₅ = -4/2 - 3 =  -5

t₆ = -5/2 - 3 = -5.5

5) In the figure, triangle ABC is a right triangle at B. If CD = 15, find BC to the nearest tenth.
ycow [4]

Answer:

BC ≈ 4.0

Step-by-step explanation:

∠ DCA = 180° - 70° = 110° ( adjacent angles )

∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle

∠ DAC = 180° - 140° = 40°

Using the Sine rule in Δ ACD to find common side AC

\frac{AC}{sin30} = \frac{15}{sin40} ( cross- multiply )

AC × sin40° = 15 × sin30° ( divide both sides by sin40° )

AC = \frac{15sin30}{sin40} ≈ 11.668

Using the cosine ratio in right triangle ABC

cos70° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{11.668} ( multiply both sides by 11.668 )

11.668 × cos70° = BC , then

BC ≈ 4.0 ( to the nearest tenth )

zlopas [31]

Step-by-step explanation:

\sqrt{(3 - ( - 4))^{2}  + ( - 7 - 6)^{2} }  \\  =  \sqrt{(3 + 4)^{2}  +  {( - 13)}^{2} }  \\  =   \sqrt{ 49 + 169}  \\   = \sqrt{218} \\  = 14.7648

Suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on
Nesterboy [21]

Answer: 49.7^{\circ}F

Step-by-step explanation:

Given

The temperature on the ground is 56.9^{\circ}F

temperature drop observed is 1.2^{\circ}F\ \text{per 1000 ft}

The height of the plane is  6000\ ft

The total increase in height per 1000\ ft is 6 units

Temperature drop is

\Rightarrow 1.2\times 6=7.2^{\circ}F

The temperature at that altitude is

\Rightarrow 56.9-7.2=49.7^{\circ}F
