Select Is a Function or Is not a Function to correctly classify each relation.
Answer:
Is a functionIsn't a functionIs a functionIsn't a functionStep-by-step explanation:
Firs we need to understand what is a function-
from a set [tex]X[/tex] to a set [tex]Y[/tex] is an assignment of an element of [tex]Y[/tex] to each element of [tex]X[/tex].
This mean's that an element in [tex]X[/tex] can't have multiples values in [tex]Y[/tex], then if you find a coordinate with two different values, isn't a function.
Take for example the second data set:
[tex]\{(2, 3), (2, 5), (3,6), (9,4)\}[/tex]
All is good except for the first two coordinates because [tex]x[/tex] is define with two different values, then you can determinate that isn't a function.
Maybe you're confuses because exist some graphs that repeat values in [tex]x[/tex] as the graph of a circle, but this in reality isn't a function, is a relation. A relation can repeat values in the set [tex]X[/tex] infinity times but never is going to be a function.

To divide the function f(x) by (x2-4x-12), we find that the quotient is Q(x) and the
remainder is (x+6). If f(-2)=a and f(6)=b, what is the value of b/a?
Answer:
b/a = 3
Step-by-step explanation:
f(x) / (x²-4x-12) = Q(x) + (x+6)/(x²-4x-12)
f(x) = Q(x)*(x²-4x-12) + (x+6)
x= - 2 ... when f(x) is f(-2) x²-4x-12 = 4+8-12 = 0
a = f(-2) = Q(x)*0 + (-2 + 6) = 4
x= 6 ... when f(x) is f(6) x²-4x-12 = 36-24-12 = 0
b = f(6) = Q(x)*0 + (6 + 6) = 12
b/a = 12/4 = 3

One weekend Bill earned 3 times as much as Jim. Tom earned $5 more than Jim. In all, they earned $60. How much did each earn?
Answer:
Step-by-step explanation:
J
B = 3J
T = J + 5
J + 3J + J + 5 = 60
5J = 55
J = $11
B = $33
T = $16
The amount earned by Jim, Bill and Tom is equal to [tex]\boldsymbol{\$ 11},\boldsymbol{\$ 33},\boldsymbol{\$ 16}[/tex].
"Important information"Let .
The amount earned by Jim be [tex]\boldsymbol{x}[/tex].
Amount earned by Bill [tex]=\boldsymbol{3x}[/tex]
Amount earned by Tom [tex]=\boldsymbol{x+5}[/tex]
Total amount earned by all [tex]=\boldsymbol{\$ 60}[/tex][tex]x+3x+x+5=60\\5x=55\\x=11[/tex]
So,
Amount earned by Jim [tex]=\boldsymbol{\$ 11}[/tex]
Amount earned by Bill [tex]=3(11)[/tex] [tex]=\boldsymbol{\$ 33}[/tex]
Amount earned by Tom [tex]=11+5[/tex] [tex]=\boldsymbol{\$ 16}[/tex]

In the gift shop of the History of Flight museum, Elisa bought a kit to make a model of a jet airplane. The actual plane is 27 feet long with a wingspan of 18 feet. If the finished model will be 13.5 inches long, what will the wingspan be?
The length of the wingspan of the finished model based on the dimensions of the kit is 0.75 feet
Given:
Kit
Plane = 27 feet
wingspan = 18 feet
Model:
Plane = 13.5 inches
Wingspan = x feet
convert 13.5 inches to feet
1 feet = 12 inches
13.5 inches = 1.125 feet
So,
equate Ratio of plane to wingspan
27 : 18 = 1.125 : x
27/18 = 1.125 / x
cross product
27 × x = 18 × 1.125
27x = 20.25
x = 20.25/27
x = 0.75 feet
Therefore, the length of the wingspan of the finished model based on the dimensions of the kit is 0.75 feet

Question 9

Step-by-step explanation:
Given,
x² - 2x - 3 = 0
x² - (3x - x) - 3 = 0
x² - 3x + x - 3 = 0
x(x - 3) + 1(x - 3) = 0
(x - 3)(x + 1) = 0
x = 3 & -1
Now,
a and b are integers
So
a = 3 & b = -1 or
a = -1 & b = 3
Answer:
a = 3 , b = -1 or a = -1 , b = 3
Step-by-step explanation:
x² - 2x - 3 = 0
x² - 3x + 1x - 3 = 0
x ( x - 3 ) +1 ( x - 3 ) = 0
( x - 3 ) ( x + 1 ) = 0
So,
x - 3 = 0 or x + 1 = 0
x = 0 + 3 x = 0 - 1
x = 3 x = -1
Therefore,
( x - a) ( x - b )
As a and b are integers
It can be,
a = 3 , b = -1 or a = -1 , b = 3

and t is the number of years since 1800
What was the population in 2020?
P(220) = [?] million
Round your answer to the nearest thousandth.
Answer:
19.193 million
Step-by-step explanation:
Put the given value in the formula and do the arithmetic.
P(220) = 19.71/(1 +61.22e^(-0.03513·220))
P(220) = 19.71/(1 +61.22e^-7.7286) = 19.71/(1 +0.02694046)

How long will it take $5500 to grow to $7400 at an interest rate of 5% it the interest is compounded continuouslyRound the number of years to the
nearest hundredth
see score
Answer:
5.93 years
Step-by-step explanation:
The continuous compounding formula tells you the amount after t years will be ...
A = Pe^(rt) . . . . principal P compounded continuously at annual rate r for t years
7400 = 5500e^(0.05t)
ln(7400/5500) = 0.05t . . . . divide by 5500, take natural logs
t = 20×ln(74/55) ≈ 5.93
It will take about 5.93 years for $5500 to grow to $7400.
