I don’t know if this is correct Will mark Brianliest

The lee family bought their home for $220,000 this year. the equation =220,000(1.038) v = 220 , 000 ( 1 . 038 ) x can be used to find the value, v, of their home after x years. which will be the value of the lee family's home in 5 years?

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

See attachment below and find the equivalent of tan(∠qsr)
