It is a function. Every x value is different.
Answer:
y = 5√2/2
x = 5
Step-by-step explanation:
First find y using the tan method: opposite/adjacent
tan(45) = 5√2/2 ÷ y
y = 5√2/2 ÷ tan(45)
y = 5√2/2
Then find x using the pythagoris theorem: c^2 = a^2 + b^2
x = √ (5√2/2)^2 + (5√2/2)^2
x = 5
Answer:
2701.125
Step-by-step explanation:
fifth term = 18(3.5)^4
-2x+y. You have to distribute 1/2 to -4x and 2y which will get -2x+ y as a expanded version
