Quick question, why didn't you just use the calculator on the device you took this photo with? Anyway, the answer is 5.62
y = sqrt(9 * 16).
This formula is derived because of similar parts of similar right triangles.
It is called the geometric mean which you can google for right triangles that share a common side.
y = sqrt(144)
y = 12
D is the only possible answer.
=============
x = sqrt(9^2 + 12^2)
x = sqrt(81 + 144)
x = sqrt(225)
x = 15
=============
z = sqrt( (9 + 16)^2 - 15^2)
z = sqrt( 25^2 - 15^2)
z = sqrt(625 - 225)
z = sqrt(400)
z = 20
Answer D
z =
Answer:
The constant of proportionality is 3.50.
Step-by-step explanation:
We know that when y directly varies with x, such that
The number 'k' is called the constant of proportionality.
Given the equation
as
so
∵
Here the value of k = 3.50, which is the constant of proportionality.
Therefore, the constant of proportionality is 3.50.
Answer:
Step-by-step explanation:
f(x)=g(x)
x²-13x+40=x-5
x²-14x+45=0
both towns are the same length because they are the same distance away from each other.
