Answer:
-5/6= -0.8333
And
8/3=2.67
On the number line they will be
The length and width that will maximize the area are 175 ft and 87.5 ft respectively
The largest area that can be enclosed is 15312.5 ft²
<h3>Area of a rectangle</h3>
where
l = length
w = width
The fencing is 350 ft it is use to enclose a rectangular plot with a river occupying one part.
Therefore,
perimeter = l + 2w
350 = l + 2w
l = 350 - 2w
area = (350 - 2w)w
(350 - 2w)w = 0
where
w = 0 or 175
average = 175/2 = 87.5
Hence, the max area is at w = 87.5 ft
Therefore,
l = 350 - 2(87.5) = 175 ft
length = 175 ft
width = 87.5 ft
Therefore,
area = 175 × 87.5 = 15312.5 ft²
Therefore, the largest area that can be enclosed is 15312.5 ft²

Answer:
71°
Step-by-step explanation:
The angle of elevation of the hill can be obtiaed using trigonometry :
Given
the opposite length = 14.5 feets
Adjacent = 5 feets
The angle of elevation vabnbe obtained using :
Tan θ = opposite / Adjacent
Where θ = angle of elevation
Tan θ = 14.5 / 5
Tan θ = 2.9
θ = tan^-1(2.9)
θ = 70.97 = 71°
Answer:
2. quadrant 4
3. quadrant 2
4. quadrant 3
Step-by-step explanation:
You can refer to the picture.
2. Since
less than 0 which means
is negative,
less than 0 which means
is negative.
So, the angle lies in quadrant 4 (Cos quadrant)
3. Since
less than 0 which means
is negative,
less than 0 which means
is negative.
So, the angle lies in quadrant 2 (Sin quadrant)
4. Since
more than 0 which means
is positive,
less than 0 which means
is negative.
So, the angle lies in quadrant 3 (tan quadrant)
