Describe the transformations of f(x) = 2(x - 4)^2 + 6
So our function is: f(x) = [tex]2(x-4)^{2} +6[/tex]
First, we see that the origin is (4,6). This means that the origin translated 4 to the right and 6 up. Next we see that the function was stretch by a factor of 2. Therefore, the transformation this function undergoes are 4 to the right, 6 up, and a stretch of 2.

b. find the tangent ratio of angle BKG
c. find the tangent ratio of angle KDF
d. find the tangent ratio of angle BCK
e. find the XY coordinates of point g with the center k
use the image to find the answers for each part mathematics high school done
Answer:
a. tan∠FKG = √3
b. tan∠BKG = 1
c. [tex]tan\angle KDF = \dfrac{1}{\sqrt{3} }[/tex]
d. tan∠BCK = 1
e. The coordinates of the point g is (4, 4·√3)
Step-by-step explanation:
a. The trigonometric ratio for tan is given as follows;
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
Therefore, we have;
[tex]tan\angle FKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(60^{\circ}) = \dfrac{sin(60^{\circ})}{cos(60^{\circ}) } = \dfrac{\dfrac{\sqrt{3} }{2} }{\dfrac{1}{2} } = \sqrt{3}[/tex]
b.
[tex]tan\angle BKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(45^{\circ}) = \dfrac{sin(45^{\circ})}{cos(45^{\circ}) } = \dfrac{\dfrac{1 }{\sqrt{2} } }{\dfrac{1}{\sqrt{2} } } = 1[/tex]
c.
[tex]tan\angle KDF = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(30^{\circ}) = \dfrac{sin(30^{\circ})}{cos(30^{\circ}) } = \dfrac{\dfrac{1 }{2 } }{\dfrac{\sqrt{3} }{2 } } = \dfrac{1}{\sqrt{3} }[/tex]
d. In right triangle, ΔBKC, ∠BCK = ∠BKC = 45°
∴ tan(∠BCK) = tan(45°) = 1
e. The x-coordinate of the point g is 4
The y-coordinate of the point g is 4 × tan(60°) = 4·√3
The coordinates of the point g is (4, 4·√3).

what is there value of y?
what is the value of x?
Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
Answer:x=14
Step-by-step explanation:
Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.
So, we will first start off by solving for x. We do this by using inverse operations.
5x+25=3x+53 We will subtract
5x=3x+28
2x=28 Divide
x=14
You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.
We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.
5(14)+25=95
180-95=85
85 is the value of 2y+35
We will solve for y just like any other alegrbaic problem
85=2y+35
50=2y
y=25
We know know that y is 25 and x is 14
Plug both values into 2 adjacent angles and they will add up to 180.

Step-by-step explanation:
Put the equations in slope-intercept form. This will help greatly. To check solutions, substitute x and y in. To graph lines, use the slope and y-intercept. Desmos graphing calculator is very helpful if you need help. Finding solutions, just find where the lines intersect. Good luck!

if 5 pizzas cost $60, how much will 9 pizzas cost
Answer:
$108
Step-by-step explanation:
so someone ordered 5 pizzas =$60 then relized they need 9 more so they need to know how much is 9 pizzas going to cost. they did 5/60 then get 12 then they did 9 times 12 =$108
Answer:its 108 because when you divide 6/5 = 12 so 9 x 12 = 108

Explain why triangle ABC is congruent to triangle FED.
Answer:
The two angles of ΔABC are equal to the two respective angles of ΔFED. Also, the sum of all interior angles of a triangle is 180º. Therefore, third angle of both triangles will also be equal in measure.

un vaso contiene leche hasta los 3/5 de su capacidad. si echa un 1/7 mas, es seguro que la leche
A.se derramara porque supera el 100% de la capacidad del vaso
B.no se derramara porque no supera el 50% de la capacidad del vaso
C.se derramara porque la cantidad total es equivalente a la capacidad de dos vasos
D.no se derramara porque la cantidad total esta entre el 70% y el 80% de la capacidad del vaso
Answer:
De las opciones presentadas, la correcta es la D.
Step-by-step explanation:
Suma de fracciones
Dado que un vaso contiene 3/5 de su capacidad con leche, aún tiene libre una fracción que puede ser llenada.
Si se echa 1/7 más de leche, vamos a encontrar si la suma de las dos cantidades supera al 100% o también al número 1 que es la representación del vaso completo.
Sumemos:
[tex]\displaystyle \frac{3}{5}+\frac{1}{7}=\frac{3*7+1*5}{35}=\frac{21+5}{35}=\frac{26}{35}[/tex]
Como el numerador es menor que el denominador, la fracción es menor que 1 y aún cabe más leche en el vaso. Calculando el valor aproximado:
[tex]\displaystyle \frac{26}{35}\approx 0.74[/tex]
Lo cual representa un 74% aproximadamente.
De las opciones presentadas, la correcta es la D.
Solve x ^ 2 + 10x = -21.
x = 7 and x = 3
x = -7 and x = -3
x = - 7 and x = 3
x = 7 and x = -3
Answer:
X = -7, -3
(AKA B)
Answer:
x= -7 and x= -3
Step-by-step explanation:
x^2 + 10x = -21
= X^2 + 10x + 21 (Bring the -21 to the other side to make it positive)
factor the equation...
= (x+7)(x+3)
x= -7 and x= -3

A. 10x + 200 > 500; the new theater must have more than 30 seats in each row on the floor to meet fire safety regulations.
B. 10x + 200 < 500; the new theater must have fewer than 30 seats in each row on the floor to meet fire safety regulations.
C. 10x > 500; the new theater must have more than 50 seats in each row on the floor to meet fire safety regulations.

What is the slope of a line perpendicular to the line whose equation is 12x-9y=135
Answer:
[tex]\frac{-9}{12}[/tex]
Step-by-step explanation:
First, we need to isolate y.
1. Subtract 12x from both sides.
-9y=-12x+135
2. Divide by -9 in order to isolate y.
[tex]y=\frac{12}{9} x-15[/tex]
3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].

what is the measure of
a) 30 degrees
b) 40 degrees
c) 70 degrees
d) 110 degrees
Answer:
70
Step-by-step explanation:
The sum of the angles of a triangle should always add up to 180 degrees.
In this problem, they have given us 2 angle measures of the triangle - 40 degrees and 70 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.
I'm just going to do some simple math:
40 + 70 = 110 (sum of the 2 angles)
180 - 110 = 70 (subtracting 180 by the sum of the 2 angles)
