Answer:

The third option is correct: 5.7 units, M(7, 5, 2.5).

Step-by-step explanation:

The distance is √ [(9-5)^2 + (7-3)^2 + (3-2)^2 ]

= √ (16 + 16 + 1)

= √33

= 5.7.

The mid point = (9+5)/2 , (7+3)/2, (3+2)/2

= (7, 5, 2.5).

I NEED HELP FAST! Find the measure of the missing angles.

loris [4]

Angle G = 130 degrees

Angle H = 50 degrees

Angle K = 74 degrees

Angle M = 106 degrees

Angle G would be 130 degrees because it's a vertical angle, and vertical angles are always alike.

Angle H would be 50 degrees because it's an adjacent angle, and we also know that one side of the line is always 180 degrees so we have an equation that looks like this 180 - 130 = 50 degrees

Angle K would be 74 degrees because it's a vertical angle.

Angle M would be 106 degrees because it's an adjacent angle.

Sue Arva has 460 beads to make bracelets. Each bracelet will use 50 beads. How many bracelets will she be able to make? A. 9 B.

monitta

Answer:

A. 9

Step-by-step explanation:

So, she has 460 beads, and each braclet she makes requires 50 beads.

Therefore we will divide these numbers to get 9.2. This rounds to A. 9.\

The graph of the quadratic function y=-x^2-2x+3 is shown below

Karolina [17]

Answer:

The axis of symmetry is at $x=-1$

The graph has an x-intercept at $(1,0)$

The graph has a vertex at $(-1,4)$

Step-by-step explanation:

we have

$y=-x^{2}-2x+3$

Statements

case 1) The graph has root at $3$ and $1$

The statement is False

Because, the roots of the quadratic equation are the values of x when the value of y is equal to zero (x-intercepts)

Observing the graph, the roots are at $-3$ and $1$

case 2) The axis of symmetry is at $x=-1$

The statement is True

Observing the graph, the vertex is the point $(-1,4)$

The axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex

the equation of the axis of symmetry is $x=-1$

case 3) The graph has an x-intercept at $(1,0)$

The statement is True

see procedure case 1)

case 4) The graph has an y-intercept at $(-3,0)$

The statement is False

Because, the y-intercept is the value of y when the value of x is equal to zero

Observing the graph, the y-intercept is the point $(0,3)$

case 5) The graph has a relative minimum at $(-1,4)$

The statement is False

Because, is a vertical parabola open downward, therefore the vertex is a maximum

The point $(-1,4)$ represent the vertex of the parabola, so is a maximum

case 6) The graph has a vertex at $(-1,4)$

The statement is True

see the procedure case 5)

see the attached figure to better understand the problem
