R = dfrac3 t-1 + t. Brainliest please?
Answer:
2π
Step-by-step explanation:
This is a little something you have to memorize, but you could derive it from the equation pb = 2π. In the parent function, the b value is 1, so the period, p, is equal to 2π/1 or just 2π.
To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:


Now you must cross multiply
10*42 = 15*x
420= 15x
To isolate x divide 15 to both sides
420/15 = 15x/15
28 = x
Hope this helped!
