in a right-triangle, like in the 1st Quadrant, cosine and sine are complements, so then
sin(x) = cos(90° - x)
cos(x) = sin(90° - x)
for this case, sin(<u>90°</u>) = cos(90° - <u>90°</u>), or just cos(0°) = 1.
Answer:
15050
Step-by-step explanation:
Hello!
So basically, this arithmetic sequence follows the rule (3n-1). What you are looking for is the summation of (3n-1) with a lower limit of 1 and an upper limit of 100. This, plugging it into a calculator (etc. symbolab) or even calculating it manually, we get ∑↑100↓n=1⇒3n-1=15050.

Answer:
C and E
Step-by-step explanation:
2^x + 1 = 5
2^x = 4
2^x = 2²
x = 2 , y = 5
(2,5) is the solution which lies in Quadrant 1
