Answer:
106$
Step-by-step explanation:
80% off of 500$ is 100$ and 6% of 100$ is 6$ add that and u get 106$
Let C represent the temperature in Celsius, and let F represent the temperature in Fahrenheit.
F=1.8C+32
Using that equation, plug in the numbers. F=1.8*25+32. F=77
One way in which to approach this proof would be to convert
1 (cos x)^2
------------- into ---------------- . Next, note that 1 - (sin x)^2 = (cos x)^2
(tan x)^2 (sin x)^2 and that 1 - (cos x)^2 = (sin x)^2.
Then we have:
(cos x)^2 (cos x)^2
------------- = -------------------- which is a true equation
(sin x)^2 (sin x)^2
