List the coefficients of x in the expression
x - 7x2y.

Answer:

x = y = 13, z = 18

Step-by-step explanation:

6x + 8 = 86

6x = 86 - 8 = 78, so x = 78/6 = 13

7y + 3 + 86 = 180

7y = 180 - 86 - 3 = 91

y = 91/7 = 13

5z + 4 + 86 = 180

5z = 180 - 86 - 4 = 90

z = 90/5 = 18

Answer:

36 cm

Step-by-step explanation:

arc length = r × θ

32π = r × 8/9π

r = 36

The radius of the circle is 36 centimeters when the arc length is 32 centimeters and the corresponding central angle is (8/9)π radians.

A circle's arc is defined as a portion or segment of its circumference.

The length of an arc, s. of a circle having a radius r, with the central angle θ, is given as s = rθ.

In the question, we are given an arc of a circle having a length (s) = 32π centimeters, and the corresponding central angle (θ) = (8/9)π radians.

We are asked to find the radius (r) of the circle.

We know that the arc length is the product of the radius and the central angle, that is, s = rθ.

Following this, we can write:

32π = r(8/9)π,

or, r = (32π*9)/(8π) = 36.

Therefore, the radius of the circle is 36 centimeters.

Kenneth:

Area of a triangle: A = 1/2*b*h (base = 6, height = 6)

A = 1/2 * 6 * 6

A = 1/2 * 36

A = 18 square inches

Since there are two triangles, it would be 18 * 2 = 36 square inches

Area of a rectangle: A = l*w (length = 9, width = 9)

A = 9 * 9

A = 81 square inches

Add the two areas together:

b) 36 + 81 = 117 square inches

72 inches

Answer:

71 m x 45 m

Step-by-step explanation:

Length = x, Width = y

x * y = 3,195

2(x + y) = 232, so

x + y = 232/2 = 116, they y = 116 - x

x * (116 - x) = 3,195

116x - x² = 3,195

x² - 116x +[tex]x = \frac{116\pm\sqrt{116^2-4*3195}}{2}[/tex] = 71,    45

Step-by-step explanation:

The secant of the angle through a point (-5, 3) is -13/5  

The equation of a circle with center (0,0) is given by

x² + y² = r² where r = radius of circle

Now, comparing this to the equation of the given circle x² + y² = 169,

⇒ r² = 169

r = √169

r = 13

The secant of the angle through a point (x, y) is secФ = r/x where

Now for the point A(-5,12), x = -5.

Since r = 13

secФ = r/x

= 13/-5

= -13/5  

So, The secant of the angle through a point (-5, 3) is -13/5

Answer:

  {-3, -1, 1, 3}

Step-by-step explanation:

The range is the set of function values corresponding to the values in the domain. They are generally sorted into numerical order.

  range = {-3, -1, 1, 3}

__

Each value is found by evaluating the function at the domain value:

  f(-1) = 1 -2(-1) = 3

  f(0) = 1 -0 = 1

  f(1) = 1 -2(1) = -1

  f(2) = 1 -2(2) = -3
