Answer:
Step-by-step explanation:
we know that
----> by trigonometric identity
we have
substitute
Remember that
If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant
therefore
If the angle theta is on the I Quadrant the cosine will be positive
If the angle theta is on the II Quadrant the cosine will be negative
Answer:
The price of one gallon of gasoline is $3.15
Step-by-step explanation:
If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":
2.4 p = 7.56
then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:
p = 7.56/2.4
p = $3.15
so this is the price per gallon of gasoline.
Answer:The dependency ratio is an age-population ratio of those typically not in the labor force and those typically in the labor force. It is used to measure the pressure on the productive population
Step-by-step explanation:
Answer:
C (let me know if I am wrong!)
Step-by-step explanation:
We need to solve the equation.
If 5x+y = -24, then -24 - 5x = y.
x+ 3(-24-5x) = -2
= -14x-72=-2
= -14x-72+72=-2+72
= -14x=70
= -5
If x = -5, then -5 + 3y = -2.
3y = -2+5
3y = 3
y=1
So the answer is C.
