A) #3 y = x+3, if you subtract x from y there is a difference of 3 in all of them.
B) #5 y = -x^2, the y value is the negative value of x raised to the 2nd power
C)#6 y = x^2+3, if you raise the value of x to the 2nd power and then add 3 you get the y value
D)#2 y=3x-1, if you multiply the value of x by 3 then subtract 1 you get the y value
Answer:
geometric function is characterised by multiplying each term by a constant to form the next term
Answer:
<h2>
h(x) = 0.0065x+1.25</h2>
Step-by-step explanation:
Given the time length in hours of a certain airplane flight represented by the function f(x) = 0.0025x + 0.75.
The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5.
x is the number of miles for the flight
The function that represents the sum of the flight time lengths is given as h(x) as shown;
h(x) = f(x) + g(x)
To get h(x), we will substitute the functions f(x) and g(x) into formula for function h(x) as shown below;
h(x) = (0.0025x + 0.75)+(0.004x + 0.5)
Collecting the like terms;
h(x)= 0.0025x + 0.004x + 0.75 + 0.5
h(x) = 0.0065x+1.25
This gives the sum of the flight time lengths

<h3>What is relative frequency?</h3>
Relative frequency measures how often a value appears relative to the sum of the total values.
The relative frequency for middle school students whose favourite sport is baseball = 13/48 = 27%
The relative frequency for middle school students whose favorite sport is basketball = 15 / 48 = 31%
The relative frequency for middle school students whose favorite sport is football = 20 / 48 = 42%
The relative frequency for high school students whose favorite sport is baseball = 23 / 52 = 44%
The relative frequency for high school students whose favorite sport is basketball = 16 / 52 = 31%
The relative frequency for high school students whose favorite sport is football = 13 / 52 = 25%
