Answer:
y= 3x +9
Step-by-step explanation:
m= 3
The y-intercept of the line that passes through the given point (0,9) is
9 = 0(3) + b
b= 9
The equation of the line that passes through the given point (0,9) is
y =mx +b
y = 3x +9
Answer:
a line that is perpendicular to the line l
Answer:
A(-5,-1) B(-1,1) C(3,4) D(2,-4) E(0,-6)
Step-by-step explanation:
(x,y)
x being the horizontal line (going across)
y being the vertical line (up and down)
Answer:
21.44 All you need to do is divide the 2.68 by 2 then multiply it by 16
Answer:
390 Millions of bacteria particles by the end of one week.
Step-by-step explanation:
The Bacteria Growth Rate Formula is: ---> N (T) = N (0) * (1 + R) ^tT
N (0) = # of bacteria present during the beginning of the experiment
Variable R= Growth rate
Variable T= Time taken / elapsed.
Substitute the #'s for N (T)
N (0) and T from the given description
We then get the value of variable R.
220 = 20 * (1+R) ^ (24 hrs)
When solving for R, we get R = 0.105074
1 week= (7 x 24 = 168) hrs
We need to plug in the solutions
Therefore
N (168 hours) = 20 * (1+0.105074) ^168
Which is around 390 millions.
So now we know that there will be 390 millions of bacteria particles at the end of 1 week
