Answer: x = 12 degrees.
Step-by-step explanation:
The triangle ABC is a right triangle, which means that it has a right angle of 90 degrees.
This is represented by the small square on the bottom-left corner of the triangle.
The angle DBC is 78 degrees. There is also the angle of ABD, which is represented by X.
The right angle is equivalent to 78 degrees and x. You can represent this in an equation, where the sum of 78 degrees and x = 90 degrees, the right angle:
78 + x = 90
x = 12

Answer:
A. Inside the circle
Step-by-step explanation:
K(0, 0), U (6, - 4), V ([tex] \sqrt 2,\: 7)[/tex]
In order to determine whether point V lie inside, outside or on the circle, first we will find the distances between points K & U and then K & V.
KU would be radius of the circle.
If KV is smaller than KU, then V will lie inside. If KV is larger than KU, then V will lie outside And If KV = KU, then V will lie ion the circle.[tex]d(KU) = \sqrt{ {(6 - 0)}^{2} + {( - 4 - 0)}^{2} } \\ = \sqrt{ {6}^{2} + {( - 4)}^{2} } \\ = \sqrt{36 + 16} \\ \red{ \bold{ d(KU)= \sqrt{52} }} \\ \\ d(KV) = \sqrt{ {( \sqrt{2} - 0)}^{2} + {( 7 - 0)}^{2} } \\ = \sqrt{ {( \sqrt{2)} }^{2} + {(7)}^{2} } \\ = \sqrt{2 + 49} \\ \purple{ \bold{ d(KV)= \sqrt{51} }} \\ \\ \because \: d(KU) > d(KV) \\ [/tex]
Hence point V lie inside of the circle.

What is the area of the shaded region?
A. 21 mm squared
B. 24 mm squared
C. 42 mm squared
D. 48 mm squared
Hello!
Answer:[tex]\boxed{ \bf The~area~of~the~shaded~region~is~B.~24 mm^2}[/tex]
______________________________________________________
Explanation:To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex](12 · 5)
A = [tex]\frac{1}{2}[/tex](60)
A = 30 mm²
Inner:
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex](4 · 3)
A = [tex]\frac{1}{2}[/tex](12)
A = 6
30 - 6 = 24
Factorise the expression (c+2d)^2-(c+2d)(3c-7d)
Answer:
(c + 2d) • (9d - 2c)
Step-by-step:
Step 1 :
Equation at the end of step 1 :
((c + 2d)2) - (c + 2d) • (3c - 7d)
Step 2 :
Pulling out like terms :
2.1 Pull out c+2d
After pulling out, we are left with :
(c+2d) • ( (c+2d) +( (-1) * (3c-7d) ))
Answer:
(c+2d)(9d - 2c) = [tex]5dc - 2c^{2} + 18d^{2}[/tex]
Step-by-step explanation:
[tex](c+2d)^{2} - (c+2d)(3c-7d)[/tex]
[tex](c+2d)(c+2d) - (c+2d)(3c-7d)[/tex]
Both sides have (c+2d) so pull out (c+2d)
Rule: a.b + a.c = a(b+c)Rule: a.b - a.c = a(b-c)(c+2d) [(c+2d) - (3c-7d)]
(c+2d) [c+2d - 3c +7d]
(c+2d) [-2c + 9d] = (c+2d)(9d - 2c)
Rule: (a+b)( c + d) = ac + ad + bc + bd ==> Foil method(c+2d)(9d - 2c) = [tex]9dc - 2c^{2} + 18d^{2} -4dc[/tex] = [tex]5dc - 2c^{2} + 18d^{2}[/tex]

Answer:
3.2 (and the equation is 3.4 + x = 6.6)
Step-by-step explanation:
the word problem is written as:
3.4 + x = 6.6
we want to solve for x.
to isolate x by itself, subtract 3.4 from both sides. (3.4 - 3.4=0 & 6.6 - 3.4 = 3.2)
now we have x = 3.2
so x equals 3.2

Find the Two Values that x can have if X^2 -10=26
Answer:

What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c =0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the equation be f ( x )
The equation f ( x ) is x² - 10 = 26
Now , adding 10 on both sides , we get
x² = 36
Taking square roots on both sides , we get
x = ±6
We know , (-6)² = 36 and (+6)² = 36
Therefore , x can have 2 solutions , which is ±6
Hence , the two values which x can have will be +6 and -6

The two-way frequency table below shows data on behavior of students and the use of positive phone calls home as an incentive for behavior for a group of students at Lion's Lane Elementary School.
Complete the following two-way table of column relative frequencies.
(If necessary, round your answers to the nearest hundredth.)
Answer:
Step-by-step explanation:
Hello!
In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.
In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.
If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n
For the students that received the phone call:
n= 19 + 9= 28
The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68
The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32
For the students that didn't receive the phone call:
n= 8 + 6= 14
The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57
The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43

What is the y-value of the vertex of the function f(x)=-(x+8)(x-14)?
3
6
112
121
Answer:
121
Step-by-step explanation:
Given
f(x) = - (x + 8)(x - 14) ← expand factors using FOIL
= - (x² - 6x - 112) ← distribute by - 1
= - x² + 6x + 112
Given a quadratic in standard form. y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² + 6x + 112 ← is in standard form
with a = - 1 and b = 6, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into f(x) for corresponding value of y
f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121
vertex = (3, 121 ) ← with y = 121
