Answer:
<h2>A. -2</h2>
Step-by-step explanation:
Answer:
x ≈ 38.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = = , then
x = ( ) ≈ 38.7° ( to 1 dec. place )
Step-by-step explanation:
R=2m
A=πr²
A = 3.142*2*2
=12.568 m2
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is
where is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so
so the formula is or in function notation
