Answer:
3/8 tan²A
Step-by-step explanation:
sinB = √3/2 sinA and cos B= √2 cosA (from given)
Answer:
−y−1=3
Step-by-step explanation:
Which equation can be used to find the solution of (1/4)^y+1=64?
This can be solved by power of indices
(1/4)^(y+1)=64
(4^-1)^(y + 1)= 4^3
Note
(x^a)^b = x^ab
Hence:
4^(-1)(y + 1)= 4^3
4^-y - 1 = 4^3
Divide both sides by 4
−y−1=3
Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is
−y−1=3
If it is
y is diretly proportional to x
y=kx
solve for y
3x+5y=0
5y=-3x
y=-3/5x
y=kx
constant of variation is -3/5
