Answer:
Step-by-step explanation:
given that a bacteria population starts with 80 bacteria and doubles every four hours,
The function representing the number of bacteria after t hours
= 
We are to find the inverse of the function
i.e. we must make t = g(n) where g is a function of n.
Take log on both sides.
this is the inverse function.
Answer:
t = 5.25 seconds
Step-by-step explanation:
Given that,
A projectile with an initial velocity of 48 feet per second is launched from a building 190 feet tall. The path of the projectile is modeled using the equation:
It is assumed to find the time when the projectile will hit the ground. When the projectile hit the ground, its height is equal to 0 such that,
It forms a quadratic equation such that,
So, the projectile will hit the ground at t = 5.25 seconds.
Assuming you are given a picture of intersecting lines.
Switch the reasons for b) and c)
b) the angles form a linear pair , from the picture, so this is linear pair postulate
C) Then the measures add to 180, because they are supplementary. Defn of supplementary.
E) you have divided both sides of the equation by 2; or multiplied by 1/2; multiplication property of equality
F) definition of right angle
G) definition of perpendicular
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!
Answer:
the gradient is the same= 4
the y intecept is different, one is positive 1 and the other is negative 3
Answer:
{(0,-5), (1, -3), (2, -1), (3, 1)
Step-by-step explanation:
If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3
You would repeat these steps just going up by one number every time
