8 0

Answer:

10

Step-by-step explanation:

( - 1, - 2 )

Let,

x1 = - 1

y1 = - 2

( - 9, 4 )

Let,

x2 = - 9

y2 = 4

Formula : -

Distance = √ [ ( x1 - x2 )² + ( y1 - y2 )² ]

Distance = √ [ ( - 1 - ( - 9 ) )² + ( - 2 - 4 )² ]

               = √ [ ( - 1 + 9 )² + ( - 6 )² ]

               = √ [ 8² + ( - 6 )² ]

               = √ [ 64 + 36 ]

               = √100

Distance = 10

5. The scale of a map says that 8 cm represents 5 km.
sleet_krkn [62]

Answer:

a. 12.8 cm    b. 3.125

Step-by-step explanation:

To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.

Identify the Vertex: x^2 - 12x + 44
nikklg [1K]

The vertex of the given quadratic polynomial function is (6, 8)

A quadratic polynomial function is the one which can be represented in the form ax² + bx + c = y where a, b and c are coefficients and x, and y are independent and dependent variables respectively. A parabola is formed when the quadratic polynomial is plotted on graph. The x coordinate of the vertex can be found using formula (-b/2a) and y coordinate can be found by putting the value of x in the equation.

Given polynomial function x² - 12x + 44

Now, x = (-b/2a)

x = (12/2)

=> x = 6

Now, y = 6² - 12×6 + 44

y = 36 - 72 + 44

=> y = 8

Therefore, Vertex = (6, 8)
