Answer:
Step-by-step explanation:
Given expression:
To solve for to nearest tenth.
Solution:
We have:
In order to solve for we will tan inverse tan on both sides in order to isolate .
[ Since ]
We will round to nearest tenth. So,
(Answer)
Answer:
(0, 1)
Step-by-step explanation:
p(x) =2^x
- p(x) - is number of bacteria
- x - time, hour
Solution of p(x) = 1
Indicating initial number of 1 in the beginning
Coordinate of (0, 1) is the solution
Given:
The inequality is
To find:
The value of x and then graph on the number line.
Solution:
We have,
Subtracting 19 from both sides, we get
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
You just have to go 7x28=[7x20]+[7x8]=196
