Answer:
.
Step-by-step explanation:
We need to write an equation for the amount of chemical B as a function of the amount of chemical A.
...(1)
where, k is constant of proportionality.
It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.
Substitute a=15 and b=3 in (1).
Substitute 
in (1).
Therefore, the required function is .
Angle R is the reference angle as its the only given angle (other than the 90 degree angle).
Opposite angle R is segment PQ
PR is the hypotenuse
Use the sine rule to find that...
sin(angle) = opposite/hypotenuse
sin(R) = PQ/PR
sin(19) = PQ/11
11*sin(19) = PQ
PQ = 11*sin(19)
PQ = 3.58124969902872 <<-- use a calculator (degree mode)
PQ = 3.58
Answer: 3.58
It decreased by 25% every year.
if you multiply a number by a decimal you will get a smaller number than you originally had. for example, if you multiply 95 by .75 you will get 71.25 it is decreasing but only 25%
Answer:
g(-3)= 26
Step-by-step explanation:
g(x)= 3x² - 1
g(-3) means use -3 for x in the given equation.
g(-3)= 3(-3)² - 1
g(-3)= 3(9) - 1
g(-3)= 27 - 1
g(-3)= 26
