You’d add 65+79 to get 144 then subtract that from 180 and get 36 so X would be 36 :) hope this helped!
The answer is D) 3,404
By putting the table values into the progam DESMOS, and then putting in the formula, the answer will be given- and that answer is 3,404.
Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
Answer: only has one solution
Step-by-step explanation: If you find the answer for 7x+3x-8, youll get 10x+8. This will be the same answer for 2(5x-4). Making them equal and having only one solution
Answer:
Part 1) The exponential function is 
Part 2) 
Step-by-step explanation:
Part 1) Write an exponential function
we know that
The exponential growth function is given by the formula
where
y is the population
x is the number of years
a is the initial population
r is the rate of change
we have
substitute
Part 2) How much will the population be after 16 years?
For x=16 years
substitute the value of x in the exponential function
