Solve by graphing. tan(30x - 90°) = -x³
Allushta [10]

The solution to the equation is 0.07, 0.17, 0.27, 0.38........

<h3>How to determine the solution to the trigonometry equation?</h3>

The trigonometry equation is given as:

tan(30x - 90°) = -x³

We start by splitting the trigonometry equation as follows, by creating two different equations

y = tan(30x - 90°)

y = -x³

Next, we plot the graph of the trigonometry equations y = tan(30x - 90°) and y = -x³

From the graph of the trigonometry equations y = tan(30x - 90°) and y = -x³, we have the x coordinate of the point of intersection to be:

x = 0.07, 0.17, 0.27, 0.38........

Hence, the solution to the trigonometry equation is 0.07, 0.17, 0.27, 0.38........ .

Find the missing number so that the equation has no solutions 2x+2=?x+13
enyata [817]

Answer:

2

Step-by-step explanation:

2x+2=?x+13

Let x=2

2x+2=2x+13

Subtract 2x from each side

2 =13

This is never true so there is no solution

A city planner designs a park that is a quadrilateral with vertices at j(-3,1), k(1,3), l(5,-1), m(-1,-3). There is an entrance
Maksim231197 [3]
By definition, a quadrilateral is a two-dimensional figure that is composed of four sides. Since you are given with the coordinates of the vertices, the first logical thing to do is to plot the points in a Cartesian plane as shown in the attached picture. Next, find the midpoints of each side of the quadrilateral as denoted by the red dots. Then, create a line connecting the opposite midpoints which represents the length of the paths. 

Our first solution is to find the midpoint of each sides. This is done by taking the average of each coordinate. The equation would be:

x,midpoint = (x₁+x₂)/2
y,midpoint = (y₁+y₂)/2

So, applying the equation:

midpoint jk = (-3+1/2, 1+3/2) = (-1,2)
midpoint kl = (1+5/2, 3+⁻1/2) = (3,1)
midpoint ml = (5+⁻1/2, ⁻1+⁻3/2) = (2,-2)
midpoint jm = (⁻3+⁻1/2, 1+⁻3/2) = (-2,-1)

Next, we find the lengths of the paths by using the distance formula:

d = √(x₂ - x₁)² + (y₂ - y₁)²

Distance between jk and ml = √(⁻1-2)² + (2 - ⁻2)² = 5
Distance between jm and kl = √(3-⁻2)² + (1-⁻1)² = √29
Total distance = 5 + √29 = 10.385 units

Since the scale is 1 unit = 10 meters, the actual total length of paths is equal to:

Actual Total Distance = 10.385*10
Actual Total Distance = 103.85 meters
