The equation 3sinx+cos^2x=2 is solved below ! !

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side.

(A²-3A+2.25)=-1+2.25

Rewrite as perfect squares

(+/-)(A-1.5)=1.12

first solution

(A-1.5)=1.12> A=1.12+1.5> A=2.62> sin x=2.62

second solution

-(A-1.5)=1.12> -A+1.5=1.12> A=1.5-1.12> A=0.38---> sin x=0.38

the answer is

the equation was factored incorrectly

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

x=6 and x=3
