Answer:

c  

Step-by-step explanation:  

There a is parallel to d because a is perpendicular to c and c is parallel to d which is the correct answer that would be option (C).

A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.

The distinct lines​ a, b,​ c, and d are in the same plane.

a⊥b, bllc, and clld

Line a is perpendicular to line b, line b is parallel to line c, and Line c is parallel to line d which is given in the question.

Line a is perpendicular to line b (given)

Line b is parallel to line c (given)

Line c is parallel to line d (given)

Thus, Line a is parallel to line d

Therefore, a is parallel to d because a is perpendicular to c and c is parallel to d.

Hence, the correct answer would be an option (C).

Answer:

8.529325

Step-by-step explanation:

Answer:

0.539325

Step-by-step explanation:

I used a calculator.

Solution :

Given the equation :

[tex]$y = x^2 - 6x+3 $[/tex]

[tex]$y=1(x^2 - 6x +n)+3$[/tex]

[tex]$n = \left(\frac{b}{2}\right)^2$[/tex]

[tex]$n = \left(\frac{6}{2}\right)^2$[/tex]

n = 9

[tex]$y=1(x^2 - 6x +9-9)+3$[/tex]

[tex]$y=1(x^2 - 6x +9)-9+3$[/tex]

[tex]$y=1(x-3)^2- 6$[/tex]

Therefore the vertex form of [tex]$y = x^2 - 6x+3 $[/tex]  is  [tex]$y=1(x-3)^2- 6$[/tex].

Answer:

Either, (9+√69)/6 or (9-√69)/6

Step wise:

3x²-9x+1=0-------------------(i)

comparing equation onw with (ax²+bx+c=0), we get,

a=3, b=-9, c=1

now,

using Quadratic Formula,

(-b±√b²-4ac)/2a=x

{-(-9)±√(-9)²-4.3.1}/2.3=x

(9±√81-12)/6=x

(9±√69)/6=x

Taking +(ve) sign                   Taking -(ve) sign

(9+√69)/6=0                           (9-√69)/6=0

∴(9+√69)/6=0                         ∴(9-√69)/6=0

The solutions to the given quadratic equation are x = 2.884 and

x = 0.116.

The equation of the form ax² + bx +c is known as a quadratic equation.

The given equation is 3x² - 9x + 1 =0.

Solve the equation as follows:

3x² - 9x + 1 =0

Use the quadratic formula to solve the equation:

[tex]x = \frac{-(-9)\pm\sqrt{(-9)^2-4(3)(1)}}{2(3)}\\\\x= \frac{9\pm\sqrt{81-12}}{6}\\\\x=\frac{9\pm\sqrt{69}}{6}\\\\x = \frac{9\pm8.306}{6}\\\\x=\frac{9+8.306}{6}\quad\text{ or }x=\frac{9-8.306}{6}\\\\x=2.884\quad\text{ or }x=0.116[/tex]

Hence, the solutions to the given quadratic equation are x = 2.884 and

x = 0.116.

Answer:

[tex]y=(x+1)^2-1[/tex]

which agrees with the last option listed.

Step-by-step explanation:

We use the vertex form of a parabola:

[tex]y-y_v=a(x-x_v)^2[/tex]

which with the information we have becomes:

[tex]y-y_v=a(x-x_v)^2\\y-(-1)_v=a(x-(-1))^2\\y=a(x+1)^2-1[/tex]

Therefore the equation that corresponds to such vertex (-1, -1) is the last one listed among your given answer options.

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

4x - 8 = -4 (11 + 2x) (distribute the -4 to the numbers in the parenthesis)

4x - 8 = -44 + -8x (add 8x on both sides)

12x - 8 = -44 (add 8 on both sides)

12x = -36 (divide both sides by 12)

x = -3

Step-by-step explanation:

                                                  7)

Given the line

[tex]y=-x+2[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = -1

We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -1 and the point (4, 0)

[tex]y-0 = -1 (x-4)[/tex]

Writing in the slope-intercept form

[tex]y = -x+4[/tex]

Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:

                                                      8)

Note: Your line is a little bit unclear. But, I am assuming the

ine is: y = -x-1

Given the assumed line

y = -x-1

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1 and the point (4, 3)

[tex]y - 3 = 1 (x-4)[/tex]

Writing in the slope-intercept form

y-3 = x-4

y = x-4+3

y = x - 1

Thus, the slope-intercept form of the equation of the line equation perpendicular to y = -x-1 will be:

Answer:

x = [tex]24^{o}[/tex]

Step-by-step explanation:

r + s = 70 feet

Applying Pythagoras theorem to the triangle formed by cable r;

[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]

[tex]/r/^{2}[/tex] = [tex]/20/^{2}[/tex] + [tex]/8/^{2}[/tex]

[tex]r^{2}[/tex] = 400 + 64

   = 464

r = [tex]\sqrt{464}[/tex]

 = 21.541

Length of cable r is 21.54 feet.

So that,

r + s = 70 feet

21.54 feet + s = 70 feet

s = 70 feet - 21.54 feet

  = 48.46 feet

Length of cable s is 48.46 feet.

Applying trigonometric function to the triangle formed by cable s, we have;

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Sin x = [tex]\frac{20}{48.46}[/tex]

        = 0.4127

x = [tex]Sin^{-1}[/tex] 0.4127

  = 24.3746

x = [tex]24^{o}[/tex]

The measure of angle that s makes with the ground is approximately [tex]24^{o}[/tex].

Answer:

Simplifying

6x + 32 = 180

Reorder the terms:

32 + 6x = 180

Solving

32 + 6x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-32' to each side of the equation.

32 + -32 + 6x = 180 + -32

Combine like terms: 32 + -32 = 0

0 + 6x = 180 + -32

6x = 180 + -32

Combine like terms: 180 + -32 = 148

6x = 148

Divide each side by '6'.

x = 24.66666667

Simplifying

x = 24.66666667

6x + 32> -4

6x > -4 - 32

6x > -36

x > -6
