4 sin^{2} x-3=0 \\ 4 sin^{2} x=3 \\  sin^{2} x= \frac{3}{4}  \\ sinx= \pm \sqrt{ \frac{3}{4} }  \\ sinx= \frac{ \sqrt{3} }{2}  \ or \ sinx=- \frac{ \sqrt{3} }{2}  \\ x=  \frac{ \pi }{3} , \  \frac{2 \pi }{3} , \  \frac{4 \pi }{3} , \  \frac{5 \pi }{3}

Officials project that between 2010 and 2050, the population of a certain city will drastically change. The model below gives th
MaRussiya [10]

Answer:

In the year 2010, the population of the city was 175,000

Step-by-step explanation:

If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

P(t)=\frac{11}{2}t+175

The rate of change, the slope of this line, is 11/2.  If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010.  In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc.  If we plug in a 0 for t we get that y = 175,000.  That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
