In quadrant I, when sin angle is 1/2, cos angle is (sqrt3)/2
Answer:
3.6191896e+15
Step-by-step explanation:
The temp after 15 minutes is 225 degrees because the initial temp plus the rate time the number of minutes gives the current temp. in this case, 75 + 10(15) = 225
therefore, the temp after t minutes can be represented by the equation f(x) = 10t + 75
6y+y=6
4x+-6x=-2
