Which method and additional information would prove ΔONP and ΔMNL similar by the AA similarity postulate?
A. Use a rigid transformation to prove ∠NOP ≅ ∠NML.
B. Use a rigid transformation to prove ∠NOP ≅ ∠ONP.
C. Use rigid and nonrigid transformations to prove segment LN over segment ON = segment PN over segment MN.
D. Use rigid and nonrigid transformations to prove segment LM over segment ON = segment PN over segment MN.
Given:
ΔONP and ΔMNL.
To find:
The method and additional information that will prove ΔONP and ΔMNL similar by the AA similarity postulate?
Solution:
According to AA similarity postulate, two triangles are similar if their two corresponding angles are congruent.
In ΔONP and ΔMNL,
[tex]\angle ONP\cong \angle MNL[/tex] (Vertically opposite angles)
To prove ΔONP and ΔMNL similar by the AA similarity postulate, we need one more pair of corresponding congruent angles.
Using a rigid transformation, we can prove
[tex]\angle NOP\cong \angle NML[/tex]
Since two corresponding angles are congruent in ΔONP and ΔMNL, therefore,
[tex]\Delta ONP\sim \Delta MNL[/tex] (AA postulate)
Therefore, the correct option is A.
Similar triangles may or may not be congruent.
The additional information to prove ΔONP and ΔMNL are similar by AA similarity postulate is (a) Use a rigid transformation to prove ∠NOP ≅ ∠NML.
From the question, we have:
[tex]\mathbf{\triangle ONP \sim \triangle MNL}[/tex] --- ONP and MNL are similar triangles
Because the similarities of the triangles are to be proved by AA postulate, the following angles must be corresponding and congruent
[tex]\mathbf{\angle ONP \cong \angle MNL}[/tex]
[tex]\mathbf{\angle NOP \cong \angle NML}[/tex]
[tex]\mathbf{\angle PON \cong \angle LMN}[/tex]
Option (b) is incorrect because angles NOP and ONP are not corresponding angles
Options (c) and (d) are incorrect, because they prove the similarities by lines segments.
Hence, the correct option is (a).
This is so because, it proves the similarities of both triangles by using corresponding angles.

Solve the equation below using a graphing

12. e* - In 2x = 3.7
I
Answer:
x = 0.05
x = 1.57
Step-by-step explanation:
The given equation is:
[tex]e^x-\ln 2x = 3.7[/tex]
Moving all terms to the left side:
[tex]e^x-\ln 2x - 3.7=0[/tex]
Now we define a function:
[tex]y=f(x)=e^x-\ln 2x - 3.7[/tex]
The solutions of the equation are the values of x such that y=0.
Since the function cannot be solved by algebraic methods, we use a graphing tool.
Those points where the graph crosses the x-axis are solutions of the equation.
Please refer to the graph in the figure below.
We can clearly identify there are two solutions at
x = 0.05
x = 1.57

Find the first five terms of the sequence given by a 1 = 2, a n = 3 a n -1 - 1.
Answer:
2, 5, 14, 41, 122
Step-by-step explanation:
Using the recursive rule with a₁ = 2
a₂ = 3a₁ - 1 = 3(2) - 1 = 6 - 1 = 5
a₃ = 3a₂ - 1 = 3(5) - 1 = 15 - 1 = 14
a₄ = 3a₃ - 1 = 3(14) - 1 = 42 - 1 = 41
a₅ = 3a₄ - 1 = 3(41) - 1 = 123 - 1 = 122
The first 5 terms are 2, 5, 14, 41, 122
Answer:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{2\\}\\\\[/tex] = 5
[tex]a_{3\\}\\\\[/tex] = 14
[tex]a_{4\\}\\\\[/tex] = 41
[tex]a_{5\\}\\\\[/tex] = 122
Step-by-step explanation:
If I've properly understood:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{n} = 3 a_{n-1}\\[/tex] - 1
so, the first 5 terms are:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{2\\}\\\\[/tex] = 3. 2 - 1 = 5
[tex]a_{3\\}\\\\[/tex] = 3. 5 - 1 = 14
[tex]a_{4\\}\\\\[/tex] = 3. 14 - 1 = 41
[tex]a_{5\\}\\\\[/tex] = 3. 41 - 1 = 122

the city of Picayune has set aside $900,000 to build a new water tower in the shape of a cylinder. If the price per cubic foot is $10.50, what is the largest measure for the radius and height of the cylinder in order to not exceed the budget?
Answer:
So as not to exceed the budget, where π = 22/7, we have;
The radius = 10 ft and the height = 3/11 ft
For standard 40 ft. height, the radius is approximately 0.8259 ft
Step-by-step explanation:
The amount set aside for the water tower = $900,000
The price (amount) per cubic foot = $10.50
Therefore, we have;
[tex]The \ volume \ of \ the \ water \ tower \ to \ be \ built = \dfrac{The \ amount \ set aside \ for \ the \ water \ tower}{The \ price \ (amount) \ per \ cubic \ foot }[/tex]
[tex]\therefore The \ volume \ of \ the \ water \ tower \ to \ be \ built = \dfrac{\$ 900,000}{\$10.50/ft\\ ^3} = \dfrac{600}{7} ft.^3 = 85 \frac{5}{7} ft^3[/tex]
Whereby the height of a standard water tower = 40 ft., we have;
The shape of the water tower = The shape of the water tower
∴ The volume of the water tower V = π × r² × h
Where;
r = The radius of the water tower
h = The height of the water tower
Taking π = 22/7
600/7 = 22/7 × r² × h
r² × h = 600/7/(22/7) ≈ 300/11 = 100 × 3/11
Solving to get exact dimensions so as to not exceed the budget, we have;
r² × h = 100 × 3/11 = 10 × 10 × 3/11
Therefore, the radius can be 10 ft. and the height = 3/11 ft.
Or for standard 40 ft. height, we have;
r² = 600/7/(π × 40)
r ≈ 0.8259 ft.

The sum of all the angles in a triangle is equal to 180°
Since the given triangle is an isosceles ∆ therefore the angles opposite to the equal sides with also be the same.
now from the diagram: 90° + 2x° = 180°

Answer:
8.28 my guy
Step-by-step explanation:
Easy, because the 'mean' is also called the 'average'.
To find the average of a list:
1). Add up all the items on the list.
then
2). Divide the sum by the number of items on the list.
For your list:
3) 5+12+4+8+7+10+12=58
