A vertical pole, 40 feet tall, casts a shadow onto the ground. If the angle of elevation from the tip of the shadow on the groun
d to the top of the pole is θ=67∘, use the dimensions given to find the length of the shadow, a, in feet. Do not include the units in your answer.
1 answer:
Answer:
Lenght of a shadow is 96.6
Step-by-step explanation:
you may use right angle triangle to find distance if you know angle of elevation.
(a) adjacent (b) hypotenuse
(c) Opposite
we know that:
adjacent (a)=40
opposite (b)=?
tan ∅= opposite/adjacent
tan 67°=opposite/40
2.4142 * 40 = adjacent
adjacent =96.6

Answer:
Reflect the parent function over the x-axis, and translate it 8 units to the left.
Step-by-step explanation:
The given function is
The parent function is
Since there is a negative multiply the transformed function, there is a reflection in the x-axis.
Since 8 is adding, within the square root, there is a horizontal translation of 8 units to the left.
Therefore to graph the given function, reflect the parent function over the x-axis, and translate it 8 units to the left.
