The function is continuous for x>0. It goes to -\infty when x\to0 and it goes to +\infty when x\to+\infty hence its range is \Bbb{R}=(-\infty,+\infty)

A line segment has endpoints at (2,10) and (10,2). What are the coordinates of the midpoint of the line segment?
IrinaVladis [17]

Answer:

(6,6)

Step-by-step explanation:

The midpoint formula is (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ). Substitute (2,10) and (10,2) into this formula and simplify.

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) \\(\frac{2+10}{2},\frac{10+2}{2} ) \\(\frac{12}{2},\frac{12}{2} ) \\(6,6)

The length of the box is 2x - 2 and the width is x - 5. Find the perimeter. (HINT: p= 2L + 2W) Choose one.
trasher [3.6K]

Answer:

Option D: 6x-14 is the correct answer.

Step-by-step explanation:

Given that:

Length of the box = L = 2x-2

Width of the box = W = x-5

Perimeter is defined by the sum of length of all sides of the box.

Perimeter of the box = P = 2L + 2W

Perimeter of box = 2(2x-2) + 2(x-5)

Perimeter = 4x-4+2x-10

Perimeter = 6x-14

The perimeter of the box is 6x-14.

Hence,

Option D: 6x-14 is the correct answer.

Hamza is graphing the parabola represented by this equation. 3x-6y^2+6y=0<br> The answer is below!!!
aivan3 [116]

Hamza should draw the vertex at (-0.5, 0.5), the directrix at -0.625, and the focus at (-0.375, 0.5). The parabola will open to the right

The given equation is 3x-6y²+6y=0.

<h3>What is the parabola?</h3>

An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively.

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Right

Vertex: (-1/2, 1/2)

Focus: (-3/8, 1/2)

Axis of symmetry: y=1/2

Directrix: x=-5/8

The coordinate points to plot (-1/2, 1/2), (0.5, 1.21), (0.5, -1.21), (1.5, 1.5) and (1.5, -0.5).

Therefore, Hamza should draw the vertex at (-0.5, 0.5), the directrix at -0.625, and the focus at (-0.375, 0.5). The parabola will open to the right.

Ostrovityanka [42]

Answer:

1) m∠ZAY = 130°

2) m∠ZXY = 65°

3) m∠SVY = 35°

Step-by-step explanation:

1) the arc angle is the measure of the central angle which intercepts it so 130°

2)measure of the inscribed angle  is 1/2measure of intercepted Arc so 1/2 of 130° is 65°

3) In this case two chords intersect inside a circle and four angles are formed

Angle Formed by Two Chords is 1/2*(Sum of Intercepted Arcs) so

m∠SVY = 1/2( m arc RX + m arc YS) = 1/2( 15+55) =1/2 * 70 =35°
