The parabola opens towards left, this means the squared term is y with negative coefficient.
The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:

where a is any constant.
In the given options, only 1 such equation is available and that is option C.
So the answer to this question is option C
Step-by-step explanation:
Tn= a+(n-1)d
= 123 +(70-1)7
=123+(69)7
=123+483
=606 answer
Answer: Trial B is
miles longer then Trail A.
Step-by-step explanation:
Length of Trail A =
miles
=
miles =
miles.
Length of Trail B =
miles
=
miles =
miles.
Trial B is longer then Trail A by
miles
miles
miles
miles
miles
Hence, Trial B is
miles longer then Trail A.
Answer:
x = 37°
Step-by-step explanation:
the sum of the exterior angles of a convex polygon is 360° so the sum of all the angles must yield to 360°.
just a trial!!!!!
x+2x+x+10+x+18+3x+x-1=360°
9x=333
x= 37°
