A) (-3,-4)
b) -3
c) (0,-4)
d) mini = (-4,infinity)
e) (-1,0) and (-5,0)
Amount of chemical A mixed in medicine = 9.357 g
Amount of chemical B mixed in medicine = 12.082 g
Amount of chemical C mixed in medicine = 7.502 g
We have to determine the total amount of medicine he prepared in grams.
Total amount of medicine
= 9.357 + 12.082 + 7.502
= 28.941 grams
So, he prepared 28.941 grams of medicine.
Now, we have to round each chemical to the nearest tenth.
Amount of chemical A mixed in medicine = 9.357 g
Rounding to nearest tenth = 9.4 grams
Amount of chemical B mixed in medicine = 12.082 g
Rounding to nearest tenth = 12.1 grams
Amount of chemical C mixed in medicine = 7.502 g
Rounding to nearest tenth = 7.5 grams
ANSWER

EXPLANATION
We use the sine rule for solving triangles.
This is given by the formula,

From the triangle,

We multiply both sides of the equation by 60 to get,


We solve for x to obtain,


To the nearest tenth, we round to one decimal place to get,
