Answer:
Step-by-step explanation:
hello :
cos²θ +sin²θ = 1 and cosθ =4/5
(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25
sin²θ = 9/25 = (3/5)²
sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25

The fraction of an hour Payton spend on his homework is 5/6. Adding 3/6 from his reading homework and 2/6 from his math homework. If you also want to find how much minute he spend doing his homework it is 50 minutes. Every hour has 60 minutes. 20+30=50 which means that Payton also spend 50 minutes on his homework.
Just replace 'x' in c(x) by d(x)
(cod) (x) = 4(x^2+5x) - 2 = 4x^2 +20x - 2
Thats it!
Answer: option 2 is the cheapest
Step-by-step explanation:
Option 1 :
10% of 4.99 = 0.499
10% off 4.99 =
4.99 - 0.499 = 4.491
10% of 15.99 = 1.599
10% off 15.99 =
15.99 - 1.599 = 14.391
10% of 30.99 = 3.099
10% off 30.99=
30.99 - 3.099 = 27.891
Total = 4.491 + 14.391 + 27.891 = 46.773
Option 2 :
Most expensive item = 30.99
20% of 30.99 = 6.198
20% off 30.99=
30.99 - 6.198 = 24.792
Total = 24.792 + 15.99 + 4.99 = 45.772
Therefore, option 2 is cheaper by 1.001.
Hope this helped :)
