The missing length is 319 feet. It is longer than the other side. Here's the work.
Answer:
y=-2/4x + (-4.5)
Step-by-step explanation:
so first we look for the slope which is rise/run.
start with the lower point and count up two.
the count to the left and you have -2/4, thats your slope.
then you chose one point, like (1,-5)
so either using point slope form y-y1=m(x-x1) or standard form y+mx+b
im going to use standard form
plug in your points like so:
y= -2/4x +b
-5= -2/4(1) +b
-5 = -1/2 + b
-5+ 1/2 = b
-4 1/2 =b
so y should equal
y=-2/4x + (-4.5)
im not sure but i hope this helps a bit
Answer:
5,120 bacterias
Step-by-step explanation:
Given the amount of bacteria after x hours modelled by the equation:
f(x) = 20(2)^x/12
Note that x is in hours not days
To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.
24hours = 1day
xhours = 4days
x = 24×4
x = 96hours
Substituting x = 96 into the equation
f(96) = 20(2)^96/12
f(96) = 20(2)^8
f(96) = 20×2^8
f(96) = 20×256
f(96) = 5,120
The number of bacteria that will be contained after 4days is 5,120bacterias
