Cos^2 + cos^2 tan^2 (break the brackets)
Cos^2+ cos^2 • sin^2/cos^2 (divide out the cos^2)
Cos^2+ sin^2 (Cos2+ sin^2= 1)
= 1
The first one is $6, 083.26
the second account earns 11,248.64
Compare: The first account made ~6,083 dollars
The second account made ~11,249. The second account has more in 3 years than the first one did in 5 years.
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
Triangle A is an Isosceles
Triangle B is Equilateral
Triangle C is Scalene
Basically, this is saying that 80% of (x) = 2 so you have know what the whole would be. It would be 2.5 because 80% of 2.5 is 2. So because you are subtracting 7 from v to get 2.5, you have to add 2.5 to 7 to get v. V=9.5
