The measure of C'T' is √17 units after the rotation .

Rotation of a graph is a transformation in which the figure is rotated around a fixed point.

The given triangle is CAT and it has the coordinates as C(0,0) , A(-2,1) and T(-1,4).

So when the figure is rotated about a fixed point the side lengths will remain same as the original figure.

C'T' = CT = √17 (the value of CT is given)

Hence the length of  C′T′ is √17 units .

Answer:

Step-by-step explanation:

Check the picture below.

the function is the Cost function for the bagels, of course that'd depend on the price of each bagel, so the cost C(x) is dependent on how many independent bagels Naomi is buying, as you can see in the table in the picture.

now, if Naomi gets 10 bagels, that simply means that x = 10, thus the price is C(10), or namely C(10) = 1.25(10), so Naomi better check her pockets for $12.50 for the bagels, hopefully she'll get some cream cheese too and cocoa.

32% of the same people spend their time listening.

The total number of mentioned  people will be 100% or 1. Now, in the total people, the remaining ones who are not stated in the question, must be the listeners. Thus, calculating the remaining percentage of people, we will get the percentage of listeners in same people.

So, number of people who spend time speaking = 26%

Number of people who spend time speaking = [tex]\frac{26}{100}[/tex]

Number of people who spend time speaking = 0.26

Number of people who spend time writing =  23%

Number of people who spend time writing = [tex]\frac{23}{100}[/tex]

Number of people who spend time writing = 0.23

Number of people who spend time reading =  19%

Number of people who spend time reading = [tex]\frac{19}{100}[/tex]

Number of people who spend time reading = 0.19

Total number of people involved in activities other than listening = 0.26 + 0.23 + 0.19

Total number of people involved in activities other than listening = 0.68

People who spend time listening = 1 - 0.68

People who spend time listening = 0.32

Percentage of people who spend time listening = 0.32 × 100

Percentage of people who spend time listening = 32%

Hence, 32% of the same people spend their time listening.

The coordinates of A and B are-7 and 9. The coordinates of C and D are -4 and 12. AB and CD are not congruent

Congruent refers to objects that are precisely similar in size and shape. The forms stay equal no matter how they are rotated, flipped, or turned. For instance, create two circles with the same radius, cut them out, and stack them.

We'll see that they'll be placed entirely on top of one another and will superimpose one another. This demonstrates that the two circles are similar. Given that they have an equal radius and can be positioned exactly over one another, the circles below are considered to be congruent. "≅" is the sign used to represent the congruence of figures. Since circle A and circle B are similar, we may say the following: Circle B ≅ Circle A.

Lets assume AB and CD are congruent

Then according to Pythagoras theorem

Hypotenuse of AB of right-angled triangle AOB is equal to Hypotenuse of CD of right-angled triangle COD

Hypotenuse AB = Hypotenuse CD

Hypotenuse AB

a² + b² = c²

(-7)² + 9² = c²

49 + 81 = c²

130 = c²

Hypotenuse CD

a² + b² = c²

(-4)² + 12² = c²

16 + 144 = c²

160 = c²

Here, 130 ≠ 160

So, The coordinates of A and B are-7 and 9. The coordinates of C and D are -4 and 12. AB and CD are not congruent

x=6

The values of x will be 2 and -1.

Given that:-

[tex]14x+17=2(x+3)^2-5[/tex]

We have to find the value of x.

As it is a quadratic equation, there will be two values of x.

Opening the bracket and solving the equation further, we get,

[tex]14x+17=2(x^2+9+6x) -5\\14x+17 = 2x^2 +18+12x-5\\2x^2-2x-4 = 0\\2(x^2-x-2) =0\\x^2-x-2 = 0[/tex]

Using middle-term split theorem to solve the quadratic equation, we get,

[tex]x^2-x-2 = 0\\x^2+x-2x-2=0\\[/tex]

x(x + 1) - 2(x + 1) = 0

(x + 1)(x - 2) = 0

Hence, either x + 1 = 0 or x - 2 = 0 or both of them are 0.

x + 1 = 0

x = -1

x - 2 = 0

x = 2

The required value is:

Answer:

[tex]\dfrac{a+b}{a-b}=-\sqrt{2}[/tex]

Step-by-step explanation:

Given:

[tex]a^2+b^2=6ab[/tex]

[tex]0 < a < b[/tex]

Add 2ab to both sides of the given equation:

[tex]\implies a^2+b^2+2ab=6ab+2ab[/tex]

[tex]\implies a^2+2ab+b^2=8ab[/tex]

Factor the left side:

[tex]\implies (a+b)^2=8ab[/tex]

Subtract 2ab from both sides of the given equation:

[tex]\implies a^2+b^2-2ab=6ab-2ab[/tex]

[tex]\implies a^2-2ab+b^2=4ab[/tex]

Factor the left side:

[tex]\implies (a-b)^2=4ab[/tex]

Therefore:

[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=\dfrac{8ab}{4ab}[/tex]

[tex]\implies \dfrac{(a+b)^2}{(a-b)^2}=2[/tex]

[tex]\textsf{Apply exponent rule} \quad \dfrac{a^c}{b^c}=\left(\dfrac{a}{b}\right)^c:[/tex]

[tex]\implies \left(\dfrac{a+b}{a-b}\right)^2=2[/tex]

Square root both sides:

[tex]\implies \sqrt{\left(\dfrac{a+b}{a-b}\right)^2}=\sqrt{2}[/tex]

[tex]\implies \dfrac{a+b}{a-b}=\pm\sqrt{2}[/tex]

As 0 < a < b then:

Therefore:

[tex]\implies \dfrac{a+b}{a-b}=\dfrac{+}{-}=-[/tex]

So:

The spam of the sets of vector of all linear combination is 0,

v 2 = (1, 1, 1).

this defines a plane in R 3.

Since a normal vector to this plane in n = v 1 x v 2 = (2, 1, −3),

the equation of this plane has the form 2 x + y − 3 z = d for some constant d. the plane must contain the origin—it's a subspace— d must be 0.

No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line

Reason:

Let's go through the answer choices.

Raymond's account balance after depositing two deposits of $100 , purchase of $86.72 with overdrawn amount $32.55 is equal to $80.73.

As given in the question,

Raymond's bank account has:

Overdrawn amount in bank = $32.55

Deposits amounts by Raymond's = 2 × ( $100 )

                                                       = $200

Purchase amount = $86.72

Account balance in Raymond's account = ( $200 - $32.55 - $86.72 )

                                                                  = ( $200 - $119.27 )

                                                                  = $80.73
