Answer:
Opens upward
Step-by-step explanation:
Since the coefficient of 
is a positive number +8, then it is a parabola that opens upward
Answer:
B
Step-by-step explanation:
Si cuentas desde el once hasta el espacio entre A y B llegas hasta 5. Entonces el número que está en ese espacio es 11.05
L=R*angle, but the angle *must* be in radians. So, just translate 43 degrees into radians: 43 * pi / 180, and you'll get:
L = 42 * ( 43 * pi / 180 ) ~ 31.504666, which rounded to the nearest hundredth is 31.50 cm.
The answer must be A or B. Since the person is trying to pay for AS MUCH people as possible. So, therefore the answer is A.
