The surface of interest can be parameterized by
with
and
.
The area of the surface
is given by the surface integral
We have
so the area is given by the double integral
This triangle is classified as a right triangle because it contains one right angle (90 degrees).
An obtuse triangle is given that classification when one of the angles is greater than 90 degrees.
An acute triangle is any triangle that has all 3 angles less than 90 degrees.
The answer should be
12ft^3
12cm^3
12yd^3
12in^3
Answer:
add up c
Step-by-step explanation:
Answer:
The minimum distance x that a plant needing full sun can be placed from a fence that is 5 feet high is 4.435 ft
Step-by-step explanation:
Here we have the lowest angle of elevation of the sun given as 27.5° and the height of the fence is 5 feet.
We will then find the position to place the plant where the suns rays can get to the base of the plant
Note that the fence is in between the sun and the plant, therefore we have
Height of fence = 5 ft.
Angle of location x from the fence = lowest angle of elevation of the sun, θ
This forms a right angled triangle with the fence as the height and the location of the plant as the base
Therefore, the length of the base is given as
Height × cos θ
= 5 ft × cos 27.5° = 4.435 ft
The plant should be placed at a location x = 4.435 ft from the fence.
