S (ABCD) = S (ABC) + S (ADC)

_____________________________________________

<h2>Reminder :</h2>

Area of the triangle = ½ × base × height

_____________________________________________

Thus :

S (ABCD) = ( \frac{1}{2}   \times 10 \times 3) + ( \frac{1}{2}  \times 10 \times 5) \\

S (ABCD) = 15 + 25

S (ABCD) = 40 \:  \:  {cm}^{2}

There you go...

Have a great day ❤

Answer:

  • 5/18

Step-by-step explanation:

<u>Let the numerator be x.</u>

  • 1/9 < x/ 18 < 1/3
  • 2/18 < x / 18 < 6/18
  • 2 < x < 6
  • x = {3, 4, 5}

<u>Fractions that satisfy the condition:</u>

  • 3/18, 4/18, 5/18

<u>The first two can be simplified further:</u>

  • 3/18 = 1/6, 4/18 = 2/9

The answer is 5/18

A satellite is 13,200 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the sa
Fudgin [204]
There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.

AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then

(x + 4000)^2 = (13200)^2 + (4000)^2
<span>x = sqrt(13200^2 + 4000^2) - 4000
   = 13793 - 4000
   = 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.</span>

Find the derivative of the function.. y = cot2(sin θ).
lana66690 [7]
Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
 dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
