We will simplify the left hand side of the equation to look like the right
taking the LCM
expanding the binomial in the numerator
Since sin²x + cos²x = 1
factoring out the 2 from the numerator
1-sin(t) will cancel out
since cos²(t) = 1/(sec²(t))
which is equal to the right hand side of our given equation.
So we verified the identity!
A function is denoted as y = f (x), where x is the argument or input of the function. This means that from f(6) follows that x= 6, and to get the answer we should replace x with 6.
f(6)=6^2÷ 3 + 6= 36÷ 3 + 6= 12+6= 18
f(6)=18
Answer:
Step-by-step explanation:
area of base = 240 in²
volume = (area of base)× height
2880 in³ = 240 in² × height
height = 2880/240 = 12 in
Answer:
x=30
Step-by-step explanation:
180=40+(4x+20) 180-40
140=4x+20 140-20
120=4x 120/4
30=x
