−20x+24=0, which number would have to be added to "complete the square"?
Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
[tex]y = a(x - h)^2 + k[/tex]
In which a is the leading coefficient.
In this problem, the equation is:
[tex]x^2 - 20x + 24[/tex]
Placing it in vertex form, we would have:
[tex](x - 10)^2 + 24 + c[/tex]
Applying the square of the subtraction:
[tex](x - 10)^2 = x^2 - 20x + 100[/tex]
Hence, a number of -100 would have to be added to complete the square.

Suppose two triangles are similar and one pair of sides of the triangles are congruent. Are the triangles necessarily congruent? Explain your reasoning.
Answer:
Yes. For the triangles to be similar, all of the sides have to be proportionate to its corresponding side. If the ratio of one of the pairs sides of the triangles is 1:1, then all of the pairs of sides on the triangles have to also have a ratio of 1:1. Using this, according to SSS postulate, the two triangles are similar. With the given information, either both triangles are congruent, or they are not similar.

Determine the length of GH. Round to the nearest tenth.
3.9 cm
G
52
642
H
Answer:
|GH| = 5,7 cm
Step-by-step explanation:
To know |GH|, you first need to find the length of |GD|.
We can calculate |GD| by;
cosG = |GC| / |GD|
<=> |GD| = |GC| / cosG
=> |GD| = 3,9 cm/ 0,62 = 6,33 cm
We now can easily calculate |GH| with the sinus of angle D;
sinD = |GH| / |GD|
<=> |GH| = sinD.|GD|
=> |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

Use the following trinomial to answer the questions. x^2-6x-27 When going through the process of determining the factors, the two factors need to : add up to ___ multiply to ___
Answer:
The factors are 3 and -9
Step-by-step explanation:
The given trinomial is [tex]x^2-6x-27[/tex].
We need to find two factors. We know that,
3(9) = 27
So,
[tex]x^2-6x-27[/tex] can be written as :
[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.
Hence, the factors are 3 and -9.

Quotient is the answer to a division problem, so we need to find a problem that needs to divide x and y to find the answer. It isn't A or B, since they are asking for y, not the quotient. I have no idea what D is. C makes sense, so C might be the answer.
It tells us how much time he has(x), and how long it takes him to make 1 bag(y), and we need to find the answer, which is the quotient.
So C is the answer.

what is the measure of angle 1
A.15 degrees
B. 25 degrees
C. 75 degrees
E. 105 degrees
what is the measure angle of angle 2
a.15 degrees
b.25 degrees
c.75 degrees
e. 105 degrees
what is the SUM of angles 6 and 7?
Answer:
Angle 1 is 75 degrees (c) & Angle 2 is 105 degrees (e)
Sum of 6 & 7 is 180
Step-by-step explanation:
75 degrees is directly across from angle 1, meaning they are the same. These are vertical angles.
Angle 2 & 75 degrees are supplementary angles, meaning they add up to 180 degrees.
Knowing that, we can do 180 - 75 = 105
6 & 7 are also supplementary, meaning that they are equal to 180 (a straight line).
Hope this helped. :)

In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted? (1 point)
Group of answer choices
Down 5, left pi over 2
Up 5, left pi over 2
Up 5, right pi over 2
Down 5, right pi over 2
Answer:
The first option:
Down 5, left pi/2.
Step-by-step explanation:
Let's define the translations in a general way.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
if N is positive, the shift is to the left.
if N is negative, the shift is to the right.
Vertical shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x) + N
If N is positive, the shift is upwards.
If N is negative, the shift is downwards.
In this case, we have the function:
f(x) = 6*Sin(2*x + π) - 5
Where the original function was something like:
h(x) = 6*sin(2*x)
Here we can already see the vertical shift is of minus 5 units, so the shift is 5 units down.
then we get:
f(x) = h(x) - 5 = 6*sin(2*x) - 5
Now we can apply a shift to the left of π/2 units, so we get:
f(x) = h( x + π/2) - 5 = 6*sin(2*(x +π/2) ) - 5
f(x) = 6*sin(2*x +π ) - 5
Then the correct option is:
Down 5, left pi over 2
If x=9 units, y= 3 units and h= 8 units find the area of the rhombus shown about using decomposition
Answer:
72 sq. units
Step-by-step explanation:
Find the diagram attached
The rhombus is the area of the two triangles and the rectangle
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * y * h
Area of triangle = 1/2 * 3 * 8
Area of triangle = 3 * 4
Area of triangle = 12 sq.units
Area of 2 triangle = 2(12) = 24 sq. units
Area of the rectangle = length * width]
Area of the rectangle = h (x-y)
Area of the rectangle = 8(9-3)
Area of the rectangle = 8 * 6
Area of the rectangle = 48 sq. units
Area of the rhombus = 24 + 48
Area of the rhombus = 72 sq. units
Select the equation represented by the graph.
