A light bulb will consume 3,600 watts - hours in 1 day if it consumes 12,600 watts in 3 days 12 hours.
We are given that:
Consumption in 3 days 12 hours = 12,600 watts
12 hours = 12 / 24 days = 0.5 days
Days = 3 + 0.5 days = 3.5 days
Now, by using the unitary method, we get that the consumption by a light bulb in 1 day will be equal to:
3.5 days = 12,600 watts
1 day = 12,600 / 3.5 watts
1 day = 3,600 watts
Therefore, a light bulb will consume 3,600 watt - hours in 1 day if it consumes 12,600 watts in 3 days 12 hours.

What is the image of the point (-10, 6) after a 90 degree counterclockwise
rotation?
After a 90-degree counterclockwise rotation of the point (-10, 6); the image point will be (- 6, - 10) .
As we all know, when a point ( x, y ) rotates counterclockwise, then the new coordinates of the given point are ( -y, x ).
Here the given point is (-10, 6) , where x = -10 and y = 6 ; as we know after rotation new x will be -6 and new y will be -10 .
So, after rotation the new coordinates will be ( -6 , -10 ) .

The original price of the Sofa is $620
How to calculate the original price ?The original price is reduced by 60%
After this reduction the price reduced to $280
Therefore the original price can be calculated as follows
The first step is to subtract 60% from 100%

Two pages that face each other in a book have 349 as the sum of their page numbers. What is the number of the page that comes first?
Answer: 174
Step-by-step explanation:
For this problem, let's divide the number by two since we know it's a combination of two numbers in a series as they are two consecutive book pages.
349 / 2 = 174.5
Note, that the number we have is a decimal, and page numbers cannot be partial numbers, they must be integers. With this, we can take the lower and the upper of our decimal numbers to retrieve the two-page numbers.
174.5 (Upper) ==> 175
174.5 (Lower) ==> 174
With this, we can verify these numbers have a sum of 349.
175 + 174 =? 349
349 == 349
So indeed, these numbers are a sum of 349. Now that we know these are our page numbers, we know 174 will come before 175 since page numbers are sequential.

Thus, the values that split the provided data into three quarters are known as quartiles. The center point of distribution is shown by the middle portion of the quartiles. The interquartile range is determined by the difference between the higher and lower quartiles so established.
Data 26, 34, 38, 49, 65, 75, 81
First arrange the data from smallest to greatest

The equation of the line that goes through the point (2,2) and is parallel to the line going through the points (-1,6) and (1,5) can be written in the form y=mx+b where m is what and b is what?
Answer:
m = -1/2b = 3Step-by-step explanation:
You want the slope-intercept equation of the line through (2, 2) and parallel to the line through (-1, 6) and (1, 5).
SlopeThe parallel line will have the same slope. The slope is given by the equation ...
m = (y2 -y1)/(x2 -x1)
m = (5 -6)/(1 -(-1))
m = -1/2
InterceptWe need to find the y-intercept of the desired line. Solving the equation for "b", we get ...
y = mx +b
b = y -mx . . . . . . . subtract mx to find b
b = 2 -(-1/2)(2) . . . . use m=-1/2 and (x, y) = (2, 2)
b = 2 +1
b = 3
The equation we want is ...
y = -1/2x +3
Find the quotient of x^5 − 2x^3 + 1 / x^2 − 6 by any appropriate method. Given that the initial expression is of the form a(x)/b(x) , rewrite the quotient in the form q(x)+r(x)/b(x) , noting that r(x) could possibly be zero. Identify q(x) , r(x) , and b(x) .
q(x)=
r(x)=
b(x)=
The quotient in the form q(x)+r(x)/b(x) which is equal to the x^3 +4x +(24x +1 divided by x^2 − 6), and the identification q(x) , r(x) , and b(x) are as follow :q(x) = x^3 +4x
r(x) = 24x +1
b(x) = x^2 − 6
Given details in the following question are as follows:
x^5 − 2x^3 + 1 is divided by x^2 − 6
By using the divisor method :
x^5 − 2x^3 + 1 / x^2 − 6 = x3 +(4x^3+1 is divided by x^2 − 6)
= x^3 +4x +(24x +1 divided by x^2 − 6)
where we can see that the q(x) +r(x)/b(x) is equal to the x^3 +4x +(24x +1 divided by x^2 − 6)
q(x) = x^3 +4x
r(x) = 24x +1

A decimal number has 2 digits to the right of it's decimal point. If we round it to the nearest tenth, the result is 18.6. What is the maximum possible value of this decimal ?
This number can have a maximum value of 18.64.
What are decimal numbers?The decimal numeral system is the most widely used system for representing both integer and non-integer numbers. It is the Hindu-Arabic numeral system's extension to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system. Non-recurring (non-repeating or terminating, for example), recurring (repeating or non-terminating, for example), and decimal fractions are the three types of decimals (a.k.a. converting a decimal into a fraction whose denominator is a power of ten).So, when rounded to the nearest tenths, the number is 18.59.
Now, look at the number to the right of it.If that number is 5 or higher, we round the 5 to a 6.But if that number is 4 or lower, the number remains a 5.18.55 rounded to the nearest tenths equals 18.6 (because the number to the right of 5 is 5, we round up to 18.6)18.54 rounded to tenths = 18.5 (because the number to the right of the 5 is 4, so we round it to 18.5).Therefore, this number can have a maximum value of 18.64.

What is the inverse of f(x)
(x) = (x-4)² for x ≥ 4?
Answer:
4th choice [tex]\bold{f^{-1}(x) = \sqrt{x} + 4}[/tex]
Step-by-step explanation:
Definition of the inverse of a function
A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x. The domain of f becomes the range of g and the range of f becomes the domain of g
To solve for the inverse of the function [tex]f(x) =\left(x-4\right)^2[/tex]
Let [tex]y=\left(x-4\right)^2[/tex]
[tex]\mathrm{Replace}\:x\:\mathrm{with}\:y[/tex] [tex]\text{ and replace }\:y\:\mathrm{with}\:x[/tex]
[tex]x=\left(y-4\right)^2[/tex]
Switch sides
[tex]\left(y-4\right)^2=x[/tex]
Take square roots on both sides
[tex]y-4=\pm\sqrt{x}[/tex]
Add 4 on both sides to solve for y
[tex]y = \pm\sqrt{x} + 4[/tex]
We have two solutions
[tex]y=\sqrt{x}+4,\:y=-\sqrt{x}+4[/tex]
To determine which one of these to be chosen not that in the given choices we can eliminate the first two since x cannot be negative
The third choice can also be eliminated since
[tex]-\sqrt{x} + 4[/tex] is a decreasing function for [tex]x \ge 0[/tex]
So the last answer choice is correct and the inverse of[tex]f(x) = (x-4)^2[/tex]
is given by [tex]f^{-1}(x) = \sqrt{x} + 4[/tex]
Answer:4th choice [tex]\bold{f^{-1}(x) = \sqrt{x} + 4}[/tex]
Note
Domain of (x-4)² is [4, ∞) since x ≥ 4 and (x-4)² cannot be negative
Range of (x-4)² is [0, ∞)
Domain of [tex]\sqrt{x}\:+\:4[/tex] is [0, ∞)
Range of [tex]\sqrt{x}\:+\:4[/tex] is [4, ∞)
so indeed the domain of (x-4)² has become the range of [tex]\sqrt{x}\:+\:4[/tex] and the range of (x-4)² has become the domain of [tex]\sqrt{x}\:+\:4[/tex]

Omar prints a total of 143 pages on Monday and Tuesday.
So, the number of pages printed on Tuesday are:
143 - 8 = 135
So On Tuesday, Omar prints 135 pages.
let m be the amount of time, in minutes, he spends printing on Tuesday.
We need to find an equation to model the amount of time Omar spends printing on Tuesday.
number of pages printed = (rate of printing) × (amount of time, in minutes)

[(3/4), -(√5), -3, 2.5 and 0] when arranged in ascending order will be in the order of [tex][(-3),-(\sqrt{5}),0,\frac{3}{4},2.5][/tex].
As per question statement, we are provided with 5 random numbers:
[(3/4), -(√5), -3, 2.5 and 0].
We are required to rearrange the above mentioned numbers in their ascending order.
We know from basic mathematical knowledge that, any number of integer or fraction with a negative sign is less than Zero or any other positive number.
Here, we have two negative quantities [-(√5) and (-3)]. Since [tex]4 < 5 < 9\\or, \sqrt{4} < \sqrt{5} < \sqrt{9} \\or,2 < \sqrt{5} < 3\\or,(-2) > [-(\sqrt{5})] > (-3)\\or,(-3) < [-(\sqrt{5})] < (-2)[/tex]
That is, we have established our required relation between the negative numbers.
We also know that, zero is the midpoint of the number line and any other positive number is greater than zero while any negative number is less than zero. Hence, [tex][(-3) < -(\sqrt{5}) < 0][/tex] and [tex](0 < \frac{3}{4}),(0 < 2.5)[/tex].
Now, between (3/4) and 2.5, since (3/4) is a proper fraction, it means that (3/4) is less than 1, and since (1 < 2.5), therefore, [tex](\frac{3}{4} < 2.5)[/tex].
Hence, [(3/4), -(√5), -3, 2.5 and 0] when arranged in ascending order will be in the order of [tex][(-3),-(\sqrt{5}),0,\frac{3}{4},2.5][/tex].
