Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Decrease rate (d)= 7%

Number of periods (n)= 7 years

Current population (PV)= 48,000

First, to calculate the future value, we need to use the following decrease exponential formula:

FV= PV*[(1+d)^-n]

After 7 years:

FV= 48,000*(1.07^-7)

FV= 29,892

18. In the figure, o is the center of the circle passing through P, Q, R and S. If angle SOQ = 150°, find the values of x and y.

AveGali [126]

Answer:

x = 75°

y = 105°

Step-by-step explanation:

Angle subtended on the circumference of the circle is half of the angle subtended on the center of the circle.

$\therefore m\angle SRQ = \frac{1}{2} \times m\angle SOQ\\\\\therefore x = \frac{1}{2} \times 150\degree \\\\\red{\bold{\therefore x =75\degree}} \\$

Quadrilateral PQRS is a cyclic quadrilateral.

$\therefore m\angle R + m\angle P= 180\degree \\\\\therefore x + y = 180\degree \\\\\therefore 75\degree + y = 180\degree \\\\\therefore y = 180\degree - 75\degree \\\\\purple {\bold {\therefore y = 105\degree}} \\$
