Answer:

\boxed{ \bold{ \huge{ { \sf{ - 13 {x}^{2}  - 10x + 14}}}}}

Step-by-step explanation:

\sf{ - 9x - x - 7 {x}^{2}  - 6 {x}^{2}  + 8 + 6}

Collect like terms

⇒\sf{ - 7 {x}^{2}  - 6 {x}^{2}  - 9x - x + 8 + 6}

⇒\sf{ - 13 {x}^{2}  - 10x + 8 + 6}

Add the numbers

⇒\sf{ - 13 {x}^{2}  - 10x + 14}

Hope I helped!

Best regards!!

A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 210 feet (ft). If the wheel
frutty [35]

Answer:

The change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet

Step-by-step explanation:

The given information are;

The position of the seat on the Ferris wheel = The center level of the wheel

The diameter of the Ferris wheel = 210 feet

The angle of rotation of the wheel = 45° counterclockwise

The height of a point on the Ferris wheel is given by the relation;

h = A·cos(b·x + c) + d

With regards to the question, we have;

h = The height of the seat of the Ferris wheel

A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet

360/b = The period

c = The phase shift = 90°

d = The mid line = 0

For a rotation of 45° counterclockwise or-45° clockwise, we have;

b·x = 45°, therefore;

h  = 105 × cos(45° + 90°) + 0 = 105 × cos(135°) + 0

h = 105 × cos(135°) ≈ -74.25 feet

Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.
