Answer:
18
Step-by-step explanation:
On the 21st day; the 7th day of the back medication and the 3rd day of the asthma medication.
If f(x)=x^2+7x+20 has the same roots as g(x)=Ax^2+Bx+1, then
one must be a multiple of the other.
By comparison of the constant terms, we know that 20g(x)=f(x), or
g(x)=(1/20)f(x)
=(1/20)(x^2+7x+20)
=(1/20)x^2 + (7/20)x + 20/20
=(1/20)x^2 + (7/20)x + 1
Therefore A=(1/20), B=(7/20), and A+B=(1+7)/20=8/20=2/5
Answer:
A,C and E
Step-by-step explanation:
We are given that a function

We have to find three statements which describes function accurately.
Substitute x=0

We know that exponential is defined for all real numbers .
Given function is exponential function.
Therefore,
Domain=R
Range of f=y>0
Initial value means when x=0
Therefore, the initial value=3

The simplified base=
3. -155.15
4. -140.95
5. -1.40
6. 5.80
I’m not 100% sure but I think it’s right
