Answer:
[tex]2\sqrt{5}[/tex]
Step-by-step explanation:
You can use the Pythagorean Theorem, which is [tex]a^{2}+ b^{2}= c^{2}[/tex]. So the the distance from -9 to -5 is 4 and the distance from 8 to 6 is 2.
So [tex]4^{2} +2^{2} =c^{2}[/tex]. Which equals [tex]20=c^{2}[/tex].
Then you square root [tex]c^{2}[/tex] to make it c, then you do that to the other side. So you have [tex]\sqrt{20}=c[/tex].
Which equals [tex]2\sqrt{5}[/tex].
Or you can use the Distance Formula, which is [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex].
The [tex]x_{1}[/tex] is -5 and the [tex]x_{2}[/tex] is -9. The [tex]y_{1}[/tex] is 6 and the [tex]y_{2}[/tex] is 8. When you plug that in you get [tex]\sqrt{(-9--5)^{2} +(8-6))^{2} }[/tex]. When you simplify that you get [tex]\sqrt{20}[/tex].
Which equals [tex]2\sqrt{5}[/tex].

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?
Answers
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.

What is the image of the point (-10, 6) after a 90 degree counterclockwise
rotation?
Answers
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 ) .

[(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].

Using proportions, it is found that:
The value of A is of 10.The value of B is of 35.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
In the first row of the table, we are given the scale factors of 1 and 1.25. From the second row, we have that the width for a scale of 1 is of 8 inches, and for a scale of 1.25 is of A, hence:
A = 1.25 x 8 = 10.
For the third row, we have that the scale of 1 is of 28 inches, while the scale of 1.25 is of B, hence:
B = 1.25 x 28 = 35.

What is the inverse of f(x)
(x) = (x-4)² for x ≥ 4?
Answers
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]

m = (5 -6)/(1 -(-1))
m = -1/2

Answers
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%
= 100-60
= 40%
The original price can be calculated as follows
280 × 100/40
