Answer:

d=5

Step-by-step explanation:

you have to use the distance formula, making the origin (0,0) the 1st point and (4,0) the second point.

d=\sqrt{(x_{2} -x_{1})^{2}  + (y_{2} -y_{1})^{2}   }

d=\sqrt{(4-0)^{2}+(3-0)^2 }

d=\sqrt{(4)^2+(3)^2}

d=\sqrt{16+9}

d=\sqrt{25}

d=5

The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)

In this case we have:

(-4-(2))/(7-5)

(-6)/(2)

-3

A plane is flying 3900 m above the ground level. The angle of elevation from the control tower to the plane is
Tcecarenko [31]

The horizontal distance to the control tower is approximately 18506.83m

Data;

  • distance from the ground = 3900m
  • angle of elevation = 11.4 degrees
  • horizontal distance = ?

<h3>Trigonometric Ratio</h3>

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

tan\theta = \frac{opposite}{adjacent} \\tan11.4 = \frac{3900}{x}\\x = \frac{3900}{tan11.4}\\ x = 18506.83m

The horizontal distance to the control tower is approximately 18506.83m

Use braces and digits to indicate the set of whole numbers
Sergeeva-Olga [200]

Whole numbers are numbers without decimal points greater than 0.

The set of whole numbers is:

W =\{0,1,2,3,4.....\}

In the introductory part of this solution, I stated that:

  • Whole numbers do not have decimal point
  • The smallest whole number is 0

This means that the following numbers are whole numbers:

1, 9, 10, 67

While the following numbers are not:

-1, 9.0, 1.0, -67

Let W be the set of whole numbers; the set is:

W =\{0,1,2,3,4.....\}

The dots after 4 means the set still continues
