Answer:
D. 15.7 yards
Step-by-step explanation:
The safety rail makes a curved side of a quarter circle.
The length of the safety rail = circumference of the curved part only of a quarter circle = ¼*2πr
Where,
radius = 10 yards
π = 3.14
Plug in the values
= ¼*2*3.14*10
= 15.7 yards.
✅The rail is 15.7 yards long.
Answer:
Step-by-step explanation:
∠3 = 180 - ∠1 {linear pair}
= 180 - 105
= 75°
∠2 = ∠3 {Corresponding angles"
∠2 = 75
The Bernoulli equation is almost identical to the standard linear ODE.

Compare to the basic linear ODE,

Meanwhile, the Riccati equation takes the form

which in special cases is of Bernoulli type if

, and linear if

. But in general each type takes a different method to solve. From now on, I'll abbreviate the coefficient functions as

for brevity.
For Bernoulli equations, the standard approach is to write


and substitute

. This makes

, so the ODE is rewritten as

and the equation is now linear in

.
The Riccati equation, on the other hand, requires a different substitution. Set

, so that

. Then you have



Next, setting

, so that

, allows you to write this as a linear second-order equation. You have



where

and

.
Answer:
The value of the constant of proportionality r is 1
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality r
For x=5.8, y=5.8
substitute
The linear equation is
therefore
The value of the constant of proportionality r is 1
