Answer: Pi

Explanation: Pi is mathematical constant, used in maths and physics. Pi's approximate value is 3,14159. Irrational number Pi has infinitely many decimals so that's why we always say that the value is 3,14 instead of adding other decimals. It's defined as the propotion of circle's circumference to its diameter.

Brianna spots an airplane on radar that is currently approaching in a straight line,
yuradex [85]

Using the slope concept, it is found that the distance the plane traveled from point A to point B is of 14,475 feet.

<h3>What is a slope?</h3>
  • The slope is given by the <u>vertical change divided by the horizontal change</u>.
  • It's also the tangent of the angle of depression.

At point A:

  • Altitude of 6700 feet, which is the vertical change.
  • The horizontal position we want to find is x_A.
  • The angle is of 16º.

Hence:

\tan{16^{\circ}} = \frac{6700}{x_A}

x_A = \frac{6700}{\tan{16^{\circ}}}

x_A = 23365.7

At point B:

  • Altitude of 6700 feet, which is the vertical change.
  • The horizontal position we want to find is x_B.
  • The angle is of 37º.

Hence:

\tan{37^{\circ}} = \frac{6700}{x_B}

x_B = \frac{6700}{\tan{37^{\circ}}}

x_B = 8891.2

Then, the distance is of:

d = x_A - x_B = 23365.7 - 8891.2 \approx 14475

melamori03 [73]

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

sin(theta)=\frac{opposite}{hypotenuse}

sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\

a person travel 50 ft from the bottom to the top of the escalator

Carroll’s is putting a border around the edge of a rectangular bulletin board. One side of the bulletin board measures 2 feet an
olga_2 [115]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

First let's establish that the problem requires the border to be as long as the total perimeter of the rectangular bulletin board.

Therefore:

Total length of border = Perimeter of rectangular bulletin board

As a rectangle has a total of four sides with two equivalent longer sides and two equivalent shorter sides, we must multiply the value of each of the two sides by two.

Total length of border = 2 ( 2 ) + 2 ( 4 )

Total length of border = 4 + 8

Total length of border = 12 feet

12 > 10

ANSWER:

Therefore, 10 feet of border isn't enough.
