Answer:
Biased
Step-by-step explanation:
I thing this question is a little bias because it could imply that the more cars your family owns, the richer you are. There could be some other instances where this is not the case, but overall this could be taken as bias.
If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?
-4
-2
2
4
Answer:
x = - 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= x² - 2x + 6x + 4
= x² + 4x + 4
Equating to zero
x² + 4x + 4 = 0 ← left side is a perfect square
(x + 2)² = 0, thus
x + 2 = 0 ( subtract 2 from both sides )
x = - 2

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -14), (-1,-10), (0, -6), (1, -2), (2, 2) B. (14,-2).(10,-1). (6.0), (2, 1), (-2,2) O C. (-14, 2), (-10,1),(-6,0),(-2,-1), (2-2) D. (2, -14), (1, -10), (0, -6).(-1,-2).(-2,2)
Given:
The of values of a function.
To find:
The ordered pairs that are found on the graph of the inverse function.
Solution:
If a function is defined as
[tex]f(x)=\{(x,y):x\in R,y\in R\}[/tex]
Then its inverse function is defined as
[tex]f^{-1}(x)=\{(y,x):x\in R,y\in R\}[/tex]
From the given table it is clear that, the ordered pairs of the function f(x) are :
[tex]\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}[/tex]
So, ordered pairs of the inverse function are :
[tex]\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}[/tex]
Therefore, the correct option is B.

1. [4 marks] Every morning, a boy scout raises a flag with a mass of 1.5 kg to the top of a 15.0 m
flagpole. How much work is done by the scout?
Answer:
work = force * distance
soo...
Step-by-step explanation:
force = mass * gravity
(1.5 kg )*(9.8 m/[tex]s^{2}[/tex]) = 14.7 kgm/[tex]s^{2}[/tex] or Newtons
W = 14.7 N * 15 m = 220.5 Nm and since 1 N = 1 Joule
we say 220.5 Joule
220.5 J :)

5x+2y=10 2x+y=2
To whoever answers this you're a genius :)
Step-by-step explanation:
5x + 2y = 10
2x + y = 2, 4x + 2y = 4.
Therefore (5x + 2y) - (4x + 2y) = 10 - 4, x = 6.
=> 2(6) + y = 2, y = -10.
The solutions are x = 6 and y = -10.

Determine if the expression 9x^-2 is a polynomial or not. If it is a polynomial, state
the type and degree of the polynomial.
Answer:
9x⁻² is not a polynomial
Step-by-step explanation:
A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.
A polynomial is a function written in the form of ;
f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀
The degree of a polynomial is the highest power of x in the expression
9x⁻² ----in this case, the power is negative thus this is not a polynomial.
Answer:
Not a polynomial

In formula > h²=a²+b²
We know the values of a and b.
Now simply put the values into the equation to find the answer :)
For 1, h²= 25² + 10²
h² = 625 + 100
=725
h=√(725)
=26.92 feet
Therefore height of ladder = 26.92 feet
For 2,
h²= 21²+20²
h²=441 + 400
h² = 841
h = √841
h = 29 feet
Heigh of ladder = 29 feet

The difference between Cassandra's age and Borg's age is 3 years. The sum of 8 times Cassandra's age and twice Borg's age is 94 years. How old is each
Answer:
Cassandra 10, Borg 7
Step-by-step explanation:
Let c be Casandra's age and b be Borg's age. We can set the equation c-b=3. We can also set the equation 8c+2b=94. From the first equation we get c=b+3. Substitute this for c to get 8(b+3)+2b=94. Simplify to get 10b+24=94. Subtract then divide to get Borg's age is 7. Then since Cassandra is 3 yrs older than Borg, Cassandra's age is 10

A town has a population of 20000 and grows at 4% every year. How long will it be until the population will reach 39400?
Answer:
The population will be 39400 in approximately 17 years
Step-by-step explanation:
The increase in population after t years is given by the formula
[tex]P_t = P_0(1+r)^t[/tex]
Here
P_0 is the initial population
r is the growth rate and t is time in years
So far we know,
P_0 = 20000
r = 4%
P_t = 39400
Putting the values in the formula
[tex]39400 = 20000(1+0.04)^t\\39400 =20000(1.04)^t\\\frac{39400}{20000} = (1.04)^t\\1.97 = (1.04)^t[/tex]
Taking natural log on both sides
[tex]ln |(1.04)^t| = ln |1.97|\\t\ ln\ |1.04| = ln\ |1.97|\\t = \frac{ln\ 1.97}{ln\ 1.04}\\t = 17.287\\t \approx 17[/tex]
Hence,
The population will be 39400 in approximately 17 years

Find the value of x that solves the system shown below.
y = 5x
2x - y = 18
The solution to the system is x = -6, y = -30.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We can start by substituting the first equation into the second equation, to eliminate y:
2x - y = 18
2x - 5x = 18 (substituting y = 5x)
-3x = 18
x = -6
Now that we know x = -6, we can use the first equation to find y:
y = 5x
y = 5(-6)
y = -30
Therefore,
The solution to the system is x = -6, y = -30.

Which table represents a nonlinear function?
Answer:
Choice C
Step-by-step explanation:
The only one that isn't a linear function is table C. If we take a look at table D (because it's easier and without any negatives) the x values decreases by two every time and the y values increase by 4 every time. Then when we look at table C, the x value increase by 5 which is good. But the y value increases by 2 then 4 then 8, which is why this table isn't a linear function.
The only one that is a nonlinear function is table Choice C.
What is linear function?In mathematics, linear refer to a proportional behaviour that can be modelled with a line, the functions that model this behaviour are called linear functions, and their graphs are lines.
Now, linear expression refers to an expression which has variables with an exponent equal to one.
But Nonlinear functions have a slope that varies between points.
If we take a look at table D because it's easier and without any negatives then we can see that the x values decreases by two every time and the y values increase by 4 every time.
Thus when we look at table C, the x value increase by 5 which is good. But the y value increases by 2 then 4 then 8, which is not a linear function.

What is x if: x ÷ 0.6 = 1 2/3
Answer:
x = 1
Step-by-step explanation:
Rewrite the equation to get x/0.6 = 5/3, since the division sign is the same thing as a slash sign and that 1 2/3 is equivalent to 5/3. Multiply 0.6 on both sides to get 1 as your final answer.
Answer:
1
Step-by-step explanation:
0.6 times 1 2/3 is 1. in that case, 1 divided by 0.6 is 1.66666666667, also known as 1 2/3 making x = 1
