Answer: 2x^3 + 3x^2 - 11x - 6
Step-by-step explanation: simplified
Answer: -4.775
Step-by-step explanation: 11(7/8) + 3(1/5) - (-4.775) = 15
Answer: 174in
Step-by-step explanation:
Multiply the feet # by 12 so you get the amount of feet because there are 12 inches in 1 foot.
Finally, add total amount of ribbon and 174inches will be your answer.
Answer:
<em>The height of the tree is 19.81 m</em>
Step-by-step explanation:
<u>Trigonometric Ratios
</u>
The ratios between the sides of a right triangle are called trigonometric ratios.
If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.
The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.
This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.
The trigonometric ratio that relates both legs is the tangent:

Solving for X

Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m
