Answer:
C = -30
Step-by-step explanation:
C = 5/9 (F - 32)
C = 5/9 ( - 22 - 32)
C = 5/9 ( -54)
C = -30
The given model would make the least sense to use for x=-2.75.
the given function is:
a quadratic relationship,
where
h is the height in feet
x is the time in seconds
<h3>what is kinetic energy?</h3>
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) =
h(0.25) =
h(1.75) =
h(25) =
therefore, x=-2.75 this model would make the least sense to use

4/3 is not a valid fraction for this type of problem so I am going to assume that it is 3/4. If this is a case she will need 1 and 1/4 more cups of sugar.
(9x + 20°) + 7x = 180° { supplementary angles}
or, 9x + 20° + 7x = 180 °
or, 16x = 180° - 20°
or, x = 160°/16
:. x= 10°
Now,
9x + 20° + 2y= 180° { supplementary angles}
or, 9* 10 + 20 + 2y= 180°
or, 110° + 2y= 180°
or, 2y= 180° - 110°
or, y= 70°/2
:. y= 35°
ps: double check everything, I don't have a calculator.
