8. domain=hours
range=cost
it is a function because there is a y value for ever x
9. minutes =60, 120,180, 240 (domain)
calories= 360, 720, 1080, 1440 (range)
this is also a function
Answer:
Therefore the required value of x,

Step-by-step explanation:
Given:
ΔBC is a Right Angle Triangle at ∠ B = 90°
As ∠ B = 90° , AC will be the Hypotenuse
AC = 10 = Hypotenuse
BC = y = Longer leg ( say )
AB = x = Shorter leg ( say )
To Find :
x = ?
Solution:
In Right Angle Triangle Δ ABC , By Pythagoras Theorem we get

Substituting the given values we get

Therefore the required value of x,

Answer:
z=6
Step-by-step explanation:
987/z=164.5
multiply both sides by z
Answer:
0,4, That is the y intercept.
