Answer:
1/64
Step-by-step explanation:
F(3) means to use 3 in place of x in the given equation.
f(x) = (1/4)^x
f(3) = (1/4)^3
Either use exponents rules:
= 1^3 / 4^3
= 1 / 64
or just use the meaning of exponents
= 1/4 × 1/4 × 1/4
= 1/64
Maybe I’m wrong but I tried... I added 4y to both sides and added -10 + 4y and got -6y and I bring down the -X and divided it by both sides and divided it to the -6y and my answer is -6y
Answer:
1 + cosa sina
Step-by-step explanation:
cos³a - sin³a ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
cos³a - sin³a
= (cosa - sina )(cos²a + cosa sina + sin²a)
= (cosa - sina)(1 + cosa sina) [ sin²a + cos²a = 1 ]
Then
= 
← cancel (cosa - sina) on numerator/ denominator
= 1 + cosa sina
(5 x 1000) + (3 x 100) + (8 x 10) + (2 x 1)
