Answer:

( x + 2 )² + ( y - 6 )² = 49

Step-by-step explanation:

→ Write the form of an equation of a circle

( x - a )² + ( y - b )² = r²

→ Substitute in the centre remembering to switch the signs

( x + 2 )² + ( y - 6 )² = r²

→ Substitute in radius

( x + 2 )² + ( y - 6 )² = 49

X=47.68degree

Step-by-step explanation:

tanx=56/51

x=tan^(-1)(56/51)

=47.68

Answer:

What do we know?

SOH CAH TOA

SOH stands for opposite + hypotenuse

CAH stands for adjacent + hypotenuse

TOA stands for opposite + hypotenuse

We know from above: the opposite and the hypotenuse

tanx=56/51

x=tan^(-1)(56/51)

=47.68

Answer:

$3000

Step-by-step explanation:

I= PRT÷100

where,

I = interest = 900

T= 5

R/100 = 0.06

P = ?

I= PRT/100

900= P × 5 × 0.06

P = 900÷ 0.3

P= 3000

Answer:

C, D, and E are corrects.

Step-by-step explanation:

Two plane figures are congruent if and only if one can be obtained from the other by a sequence of rigid motions. The rigid transformations are reflection, rotation, and translation. The image from these transformations will not change its size or shape.

A dilation is a nonrigid transformation that can produce enlarged or reduced images from a given pre-image.

Therefore only C, D, and E are corrects.

A. a dilation, then a translation

B. a reflection, then a dilation

C. a reflection, then a rotation

D. a rotation, then a translation

E. a translation, then a reflection

The transformations guarantee triangles MNO and PQR are congruent should be considered is option C, D, and E.

The two plane figures should be considered as the congruent when one should be obtained from the other via the sequence of the fixed motions. Here the right transformation could be in the form of reflection, rotation, and translation.

Also, the image arise form transformations should remain the same with respect to the size or shape.

Therefore only C, D, and E are corrects.

This is an incomplete question. Please find the options below.

A. a dilation, then a translation

B. a reflection, then a dilation

C. a reflection, then a rotation

D. a rotation, then a translation

E. a translation, then a reflection

Answer:

B and C are not the solution of y=3x-8

A and D are the solution of y=3x-8

Substitute x-values to the equation.

Remember that (x, y).

Answer:

Explanation:

since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.

so according to pythagoras theorem c = √(a²+b²)

x =√(13²+13²)

x = √(169+169)

x = √338

x ≈ 18.38

note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!

Answer:

B: More than 25% of the students chose football and tennis as their favorite sport to play.

Step-by-step explanation: You need to find the total, which is 50. Since it says more than 25 percent of the students chose football and tennis your answer will need to be more then 25 percent. You add football plus tennis (10+3=13). Now you set up your proportion- 50 as your whole/total, 13 as your part, and substitute you percent with a variable like (p), then 100. Cross multiply. I did a shortcut which replaces the Ice Ice Baby process, so multiply 13x100= 1300, then your product divide it by 50 ( total) 1300/50= 26. This makes the statement true.

Step-by-step explanation:

Reflection-when the shape is reflected over an axis

Rotation-when the shape is rotated around a singular point

Translation-when the shape is moved up/down or left/right

None of these change any part of the shape it just moves the shape around. :)

Answer: The answer is W=70+30x

Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.

The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.

Therefore, the weight of the table without boxes is 70 kilograms.

Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

So, if 'g' denotes the weight of the table alone, then we have,

The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

A regression model is used to determine the association and correlation between two variables

Using a graphing calculator, the sine regression model of the dataset is:

[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]

To calculate y(30), we substitute 30 for x in the equation.

So, we have:

[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]

Evaluate the product

[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]

Evaluate the difference

[tex]y =20.077 \sin(13.041) + 67.577[/tex]

Evaluate the sine value

[tex]y =20.077 *0.4570+ 67.577[/tex]

Evaluate the product

[tex]y =9.1752+ 67.577[/tex]

Evaluate the sum

[tex]y =76.7522[/tex]

Approximate

[tex]y \approx 76.8[/tex]

Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
