Answer:
Step-by-step explanation:
<h3>7) The lengths of the tangent from an external point to a circle are equal.</h3>
2x - 1 = x + 10
2x = x + 10 + 1
2x = x + 11
2x -x = 11
8) Radius : XC
Chord: CB
Diameter : AB
Name of the circle: X {a circle is named by its center}
Answer:
Step-by-step explanation:
a)
d=0.68t + 1.5 if t time is 3 hrs
d=0.68(3) + 1.5
= 2.04 + 1.5
d= 3.54 ft
b)
d=0.68t + 1.5 if d depth is 4 ft solve for t
d - 1.5 = 0.68t
(d - 1.5) / 0.68 = t
(4 - 1.5) / 0.68 = t
t = 2.5/0.68
t = 3.68 ft

Domain restrictions are values of x which are not acceptable in a function.
They may be arbitrary because we simply want to ignore them. eg y = x^2 between 0 and 4
They may make no sense in the context, eg graph a compounding investment over next 20 years.
Negative values for x make sense here.
They may avoid mathematical impossibilities eg y = (x^2 - 4x) / (x - 4) which must avoid dividing by zero, so x cannot = 4.
The graph will look like the line y = x but have a hole where x= 4
