What Is The Vertex Of Y=x2 2x + 3?O (-1,3)O (1, 2)O (3, 1)O (2, -1)

Answers

Answer 1
The answer is (1,2) for the vertex
Hope this helps
Answer 2

Answer:

vertex = (1, 2 )

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠  0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² - 2x + 3 ← is in standard form

with a = 1, b = - 2 , then

x = - [tex]\frac{-2}{2}[/tex] = 1

Substitute x = 1 into the equation for corresponding value of y

y = 1² - 2(1) + 3 = 1 - 2 + 3 = 2

vertex = (1, 2 )

What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

Given;

Side BA= [tex]\sqrt{11}[/tex]

Side AC= [tex]\sqrt{5}[/tex]

BC^2=BA^2+AC^2

BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2

BC^2= 11+5

BC^2= 16

BC= 4

Therefore, the Pythagoras theorem gives answer 4

Answers

Answer:

6^6

Step-by-step explanation:

Divide the terms with the same base by subtracting their exponents.

6^10 - 4 = 6^6

Answer:

6^6, which equals 46656

Step-by-step explanation:

So when dividing things with exponents in them, you subtract the exponents. With this, you would do:

6^10/6^4 = 6^10 - 6^4 ---> 6^6

The answer would be 6^6, which equals 46656

What is a Pythagorean theorem?

Pythagorean theorem states that in the right-angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.

Given that a 20-foot ladder is placed against a building and must just reach a window that is 8 feet of the level ground the latter will be unstable if the base is more than 15 feet from the bottom of the building.

Calculate the base of the triangle by using the Pythagorean theorem:-

H² = P² + B²

B² = H² - P²

B² = 20² - 8²

B = √( 400  - 64 )

B = √336 = 18.33 feet

Therefore, the length of the base is 18.33 feet greater than 15 feet then the ladder will be unstable.
