Answer:
y=4
Step-by-step explanation:
<h3>The triangle is divided further into 2 right triangles. So ignore the left one.</h3><h3>We know the angle of elevation is 30° and the hypotenuse is 8.</h3><h3>Looking at SOH CAH TOA we use the sine ratio in trigonometry because we have to find the side opposite to the angle given and we know the hypotenuse. </h3><h3>It is: sin 30 = y/8</h3><h3>y= 8 sin 30</h3><h3>y=4</h3>
Answer:
C) 20.44
Step-by-step explanation:
Answer:
a[1] = 2; a[n] = a[n-1] + 2
Step-by-step explanation:
The first term of the sequence is 2, so the first part of the definition is ...
a[1] = 2
Each term is 2 more than the previous one, so the rest of the definition is ...
a[n] = a[n-1] + 2

<em>Comment on recursive rules</em>
A recursive rule has two parts. The first part tells what the initial value of the sequence is. The second part relates the next term to the previous term or terms.
For arithmetic and geometric sequences, each term is related to the previous term by a constant. For an arithmetic sequence, each term is the last term plus the common difference. For a geometric sequence, each term is the last term multiplied by the common ratio.
I am in 8th and I thinks it’s 2
Right so it would be 509 sq ft
