Answer:
miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points 
From these points we can find the slope of the line .
From point slope formula 
And assigning 
and 
This slope is also the speed of the bird which is 
As by plugging the values of any coordinate point we can confirm this.
Lets put 
, y-axis is the distance so in 
minutes the the distance covered by the bird must be equal to to y-axis value which is 
miles.
Now as in 
the bird has started from y-intercept value 
so we can say that,the original distance of the bird from its nest is 
.
So the correct choices are:
and 
The birds speed is 
per minute and is away from its nest.
Answer:
21.8
Step-by-step explanation:
<span>For any point (x, y), that appears in one function, the point (y, x) must appear in the other function.
For any point (x, y), that DOESN'T appear in one function, the point (y, x) must NOT appear in the other function.
So if you find any point that DOESN'T meet the above rules, you can prove that the functions are NOT inverses of each other.
But if you want to prove that they ARE inverses of each other, you have to check ALL points in the functions, and there are infinity of them, so that's not practical. Instead, you can write f(x) like this:
y = 3x - 5
Now solve for x:
y + 5 = 3x
x = (y + 5) / 3
Now swap x and y:
y = (x + 5) / 3
This is the same as g(x). Therefore the functions are inverses of each other.</span>
Sphere
The surface area of the sphere is 80384 sq yd
Step-by-step explanation:
Given the ride goes around the widest circle of the sphere whose circumference is 502.40 yd.
The widest circle of the sphere is the plane contains the sphere's center
The circumference of the widest circle is 
where r is radius of the sphere.
The surface area of the sphere is defined as 
where r is radius of the sphere.
So 502.4 =
⇒502.4 = 2 × 3.14 × r
⇒ r = 502.4 ÷ (2 × 3.14)
⇒ 
Surface Area A =
⇒ A = 4 × 3.14 × (502.4 ÷ 6.28) × (502.4 ÷ 6.28)
⇒ A = 80384 sq yd
The surface area of the sphere is 80384 sq yd
Is that khan?? just asking if it is bc we have it to tiffin does
