Answer:
x = 9
Step-by-step explanation:
Given : A triangle with angle 39 degree.
To find : Find the value of x to the nearest tenth.
Solution : We have given
A triangle with angle 39 degree and hypotenuse = x.
Adjacent side = 7 .
Cos(theta) = .
Plug the values
Theta = 39 degree.
Cos(39) = .
x = .
x = 9.09
Nearest tenth is 9.09
Therefore, x = 9

Answer:
Part A; Initial dosage is 10 milligrams
Part B:
8.4113 milligrams after 1 hour
5.0057 milligrams after 4 hours.
Step-by-step explanation:
It is given M(h)= 10
Initial dosage is the 10 milligrams
After 1 hour, plug in h as 1
So, M(1)=10
Simplify the right side
M(1)=10(0.84113)
M(1)= 8.4113 milligrams.
Now, after 4 hours
M(4)=10
M(4)=10(0.50057)
M(4) =5.0057 milligrams
