Part (D) is not a function as he element 4 has two images in y that is 4 and 1.
We are given some relations.
We need to tell which of the following is not a function.
A relation is a function when every element of x has only one mapping on the every element of y.
That is when we put one value of x, there should not be 2 values for y.
For part (A),
It is a function as it satisfies the condition.
For part (B),
It is also a function as it also satisfies the condition.
For part (C)
It is also a function as it also satisfies the condition.
Fort part (D),
It is not a function as the element 4 has two images in y that is 4 and 1.

HELP PLEASEEEEEEEEEE
Answer:
11:50 AM
Step-by-step explanation:
We should first find the sum of the times it would take her to clean each room, along with the break time.
Kitchen = 80 minutes
Lounge = 40 minutes
Bedroom = 90 minutes
Bathroom = 35 minutes
Break = 45 minutes
[tex]\text{Total time (in minutes) } = 80 + 40 + 90 + 35 + 45 = 290.[/tex]
We should then divide this amount of minutes by 60 to find how many hours it took her.
[tex]\text{Total time (in hours) } = \frac{290}{60} = 4\frac56[/tex]
This means it took her 4 hours and 50 minutes to finish cleaning.
Therefore, if she started working at 7 AM and worked for 4 hours and 50 minutes, she was done by 11:50 AM.
When finding the difference in elevations, should you only consider the absolute value of the difference? Why or why not? HELP ME WITH THIS PLEASE!!!
No, when finding the difference in elevations we should not consider only the absolute value of the difference because elevation differences can give a negative value as well.
What is absolute value?Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We know that while measuring elevation there can be a positive value which means that the distance measured is above sea level and there can also be a negative value elevation which means that the distance measured is below sea level.
For example:
If we are measuring the difference in distance of two points below sea level.
One point is at -6 feet
Another point is at -14 feet
The difference between these points is:
= -14 - (-6)
= -14 + 6
= -8
We can have a negative difference in elevation but the absolute value will always give a positive value.
Therefore,
No, when finding the difference in elevations we should not consider only the absolute value of the difference because elevation differences can give a negative value as well.

The circumference of the circle with the radius is 50.24 inches
How to calculate the circumference of the circle?The figure represents the given parameter
On the figure, we have the diameter (d) to be
d = 16 inches
The radius of the circle is calculated using
r = d/2
So, we have
r = 16/2
Evaluate the quotient
r = 8
The circumference of the circle is then calculated as
C = 2πr
Where π is given as
π = 3.14
So, we have
C = 2 * 3.14 * 8
Evaluate the product
C = 50.24
Evaluate the product
C = 50.24
Hence, the circumference of the circle with the radius is 50.24 inches

Answer: (^ represents the exponent)
a) 10^x-1
b) 10^4x
c) c^6
Step-by-step explanation:
a) When you divide powers, you subtract their exponents. Since c = 10^x and it is being divided by 10^1, it would be the equivalent of 10^x-1
b) c= 10^x. c^4 would be equal to (10^x)^4 or [tex](10^{x})^{4}[/tex]. When powers are placed this way, you multiply their exponents. For instance [tex](3^{2})^{4}[/tex] would be [tex]3^{8}[/tex].
C) This is the same concept as part b, but reversed. 10^6x is equal to (10^x)^6, which is equal to c^6.

In an arithmetic series, s40 = 1900 and u40 = 106. find the value of the first term and the common difference.
The first term and common difference of the arithmetic series are -11 and 3.
How to solve an arithmetic series?In the arithmetic series, S₄₀ = 1900 and U₄₀ = 106
Hence,
Sₙ = n / 2 (2a + (n - 1)d)
S₄₀ = 20(2a + 39d)
S₄₀ = 40a + 780d
1900 = 40a + 780d
Uₙ = a + (n - 1)d
U₄₀ = a + 39d
106 = a + 39d
Combine the equation
a + 39d = 106
40a + 780d = 1900
20a + 780d = 2120
40a + 780d = 1900
20a = - 220
a = -220 / 20
a = -11
Hence,
106 = a + 39d
106 = -11 + 39d
106 + 11 = 39d
117 = 39d
divide both sides by 39d
d = 117 / 39
d = 3
Therefore, the first term and common difference of the arithmetic series are -11 and 3.

Answer:
y = x - 3.
Step-by-step explanation:
We use the point-slope form of the straight line:
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
So, for this line we have:
y - (-1) = 1(x - 2)
y + 1 = x - 2
y = x - 2 - 1

(A) 636
(B) 1460
(C) 1660
(D) 16,600
The value of the expression 0.036m³/₄ is determined by algebraically substituting the value of m=46 x 10⁴ and solving the radical expression.
In the given radical expression, 0.036 is a constant and m is a variable with a power of ¾.
We will solve for the variable term first which will be written as a radical and multiply it with the constant.
Substituting m=46x10⁴ in the expression 0.036m³/₄.
0.036m³/₄=0.036(46x10⁴)³/₄
Now rewrite the expression as a radical,
0.036(46x10⁴)³/₄= 0.036∜(46*104)3
Multiply the exponents within radicand term,
= 0.036∜(463*1012)
Now simplify the expression,
= 0.036∜(463*(103)4
= 0.036*103 *∜463
= 0.036*103 *∜97,336
