Answer:
i'm not sure but i think the answer is D
Step-by-step explanation:
the answer will be either A or D because the shape of the graph shows that the value of a is negative
Answer:
The average number of visitors per day is 272.
Step-by-step explanation:
Total number of visitors in the zoo in a year = 98,464
Now,we know that 1 YEAR = 365 DAYS
Also, the zoo was closed on thanksgiving, Christmas, and New Year's Eve
So, the Number of days zoo was open = Total Days in year - 3 days
= 365 - 3 = 362 days
⇒Number of visitors in 362 days = 98,464
So, 
or, the number of people visiting per day is 272.
Hence, the average number of visitors per day is 272.
Answer:
-90
Step-by-step explanation:
Answer:
1/2 cup per friend
Step-by-step explanation:
He has 1 gallon of fruit sorbet to serve to 32 friends
Note that:
1 US gallon of water (gal) = 16.00 US cups of water (cup)
16 cups/1 gallon x 1 gallon/32 friends
1/2 cup per friend
(9^x) - 3 = 2*3^x
(9^x) - 3 - (2*3^x) = (2*3^x) - (2*3^x)
(9^x) - (2*3^x) - 3 = 0
(3^2)^x - 2*(3^x) - 3 = 0
3^(2x) - 2*(3^x) - 3 = 0
3^(x*2) - 2*(3^x) - 3 = 0
(3^x)^2 - 2*(3^x) - 3 = 0
z^2 - 2*z - 3 = 0 ............ let z = 3^x
(z - 3)(z + 1) = 0
If z-3 = 0, then z = 3 when we isolate z
If z = 3, and z = 3^x, then
z = 3
3^x = 3
3^x = 3^1
x = 1
which is a solutin in terms of x
If z+1 = 0 then z = -1
If z = -1 and z = 3^x, then there are NO solutions for this part of the equation
The quantity 3^x is never negative no matter what the x value is

Answer: x = 1
