F(1) = 7
f(2) = 7 + 6 = 13
Recursive formula => f(n + 1) = f(n) + 6
Next term = 31 + 6 = 37.
Answer: 235.5 feet
Step-by-step explanation:
In this case, we have to calculate the circumference of the track. The circumference will be calculated as:
= 2πr
Diameter = 75 feet.
Radius = 75/2 = 37.5 feet
Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet
f(x)=2x^2+0x-5
Find the vertex
0/4=0=x
Input x into the equation to find y or f(x)
0+0-5=f(x)
(0,-5) = Vertex
Now find a random x coordinate to input into the equation.
Let's do 4.
32+0-5=f(x)=27
It may not look like a parabola due to it being uneven.
The crane is 139.8cm tall.
<h3>what is angle of elevation?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Using Trigonometry
tan 30 = h/y
1/√3 = h/y
y= h√3
and, tan 25= h/y+62
0.96= h/(h√3 +62)
h= 0..96 (h√3 +62)
h= 0.96*h*1.732+0.96*62
h=0.796h +28.52
0.2404h= 28.52
h= 139.8 cm
Hence, whooping crane is 139.8 cm.
