Answer:

Its AA similarity theorem

Step-by-step explanation:

correct on edge 2021

The triangles ABC and EDC are similar by AA similarity theorem.

Two triangles are said to be similar if their corresponding sides are in equal ratio and corresponding angles are congruent.

Given is a proof of showing △ ABC ~ △ EDC

The proof is as follows :-

           Statement                                                Reason

            AB ∥ DE                                                     Given

         ∠ ACB = ∠ ECD                           definition of vertical angles  

         ∠ BDE ≅ ∠ DBA                   alternate interior angles are congruent

         △ ABC ~ △ EDC                                 AA similarity theorem

AA similarity theorem :-

AA similarity theorem states that when two corresponding angles of two triangles are found congruent then the triangles are similar by AA similarity theorem.

Hence, the missing reason is AA similarity theorem.

Answer:

The present age of the artifact is 1,600 years

Step-by-step explanation:

let the present age of the artifact = x

let the present age of the book, = y

x = 4y ---- equation (1)

x + 200 = 3(y + 200) ------equation (2)

x + 200 = 3y + 600

substitute in the value of x into the equation;

4y + 200 = 3y + 600

4y - 3y = 600 - 200

y = 400

Then, x = 4 x 400

x = 1,600 years

Therefore, the present age of the artifact is 1,600 years

This is GP with the common ratio of -2 as:

Correct choice is (C)

Answer:

b is correct

Step-by-step explanation:

The product of the functions M(x) and n(x) is x³+ 4x².

To find the product of the two functions, M(x) = x² + 4x and n(x) = x, we need to multiply them together.

So, (mn)(x) = M(x) × n(x)

Substituting the given functions:

(mn)(x) = (x² + 4x) × x

Now, we can simplify the expression by applying the distributive property of multiplication:

(mn)(x) = x × x² + x × 4x

Simplifying further:

(mn)(x) = x³ + 4x²

Therefore, the product of the functions M(x) and n(x) is x³+ 4x².

#SPJ6

Answer:

So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.

Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.

Slope= (180-100)

          ----------------    = -2

          (960-1000)

Formula: y=-2(x-1000)+100

Part B: y=-2(980-1000)+100=140

140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.

Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.

Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

Answer:

The sum of the first 12 terms of the sequence is 2703.673096

Step-by-step explanation:

The nth term of a geometric progression is a(n) = [tex]ar^{n-1}[/tex], where

The sum of n terms of the geometric progression is s(n) = [tex]\frac{a(r^{n}-1)}{r-1}[/tex]

∵ The third term of a geometric progression is [tex]\frac{63}{4}[/tex]

∴ a(3) = [tex]\frac{63}{4}[/tex]

∵ a(3) = ar²

→ Equate its two right sides

∴ ar² =  [tex]\frac{63}{4}[/tex] ⇒ (1)

∵ The sixth term is [tex]\frac{1701}{32}[/tex]

∴ a(6) = [tex]\frac{1701}{32}[/tex]

∵ a(6) = a[tex]r^{5}[/tex]

→ Equate its two right sides

∴ a[tex]r^{5}[/tex] =  [tex]\frac{1701}{32}[/tex] ⇒ (2)

→ Divide (2) by (1)

∴ r³ = [tex]\frac{27}{8}[/tex]

→ Take ∛  for both sides

∴ r = [tex]\frac{3}{2}[/tex] = 1.5

→ Substitute the value of r in (1) to find a

∵ a(1.5) = [tex]\frac{63}{4}[/tex]

∴ 1.5a = 15.75

→ Divide both sides by 1.5

∴ a = 10.5

→ Let us find the sum of the first 12 terms

∵ n = 12, a = 10.5, and r = 1.5

→ Substitute them in the rule of the sum above

∵ s(12) = [tex]\frac{10.5(1.5^{12}-1)}{1.5-1}[/tex]

∴ s(12) = 2703.673096

∴ The sum of the first 12 terms of the sequence is 2703.673096
