Step-by-step explanation:
Answer:
Question 13: For age groups y=1 and y=1.3 response is 8 microseconds.
Question 14: The club was making a loss between 11.28 and 4.88 years.
Step-by-step explanation:
Question 13:
The age group y for which the response rate R is 8 microseconds is given by the solution of the equation
We graph this equation and find the solutions to be
Since only positive solutions for y are valid in the real world we take only those.
Thus only for age groups y=1 and y=1.3 the response is 8 microseconds.
Question 14:
The footbal club is making a loss when 
Or
We graph this inequality and find the solutions to be
and 
Since in the real world only positive values for t are valid, we take the the second solution to be true.
Thus the club was making a loss in years
These are a lot easier when they r like this...no coefficient in front of ur x^2.
x^2 + 5x - 14....u see ur last sign, the -.....this tells me that in ur 2 factors, both signs will be different....one is positive and one is negative. U see ur first sign, the +, this tells me that ur bigger number will be positive.
Now we just have to find 2 numbers, that when added = 5 and when multiplied = 14, So ur 2 numbers are 7 and 2.
(x^2 + 5x - 14) =
(x + 7)(x - 2) <===
I got you covered. There are two ways to write Θ: degrees [°] and radians [expressed as "π"]. So, in this case cos π/3 = ½ [radian measure], or cos 60° = ½ [degree measure]. The reason being is because to convert from degrees to radians, use this formula: [degree measure] π/180; if you were to convert from radians to degrees, you'd do this vice versa: [radian measure] 180/π. So basically, the unit you're trying to convert to, is the one that goes in your numerator.
