Answer:
The value of the computer is given by 
.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
<h3>
Answer: x = 90</h3>
============================================
Explanation:
The arc measure is some unknown number x, so is the angle formed by the tangents that form based on this arc. The arc and angle add to 180, so,
x+x = 180
2x = 180
2x/2 = 180/2
x = 90
A right angle forms if we were to draw segments from the center of the circle to the points of tangency. We have a square forming if we do so. Recall that the points of tangency have the radius and tangent segments meet up at a 90 degree angle.
Edit: Bottom left is correct.
