The price of a computer component is decreasing at a rate of 11% per year. state whether
this decrease is linear or exponential. if the component costs $120 today, what will it cost
in three years?
is the decline in price linear or exponential?
linear
o exponential

Question 1:

In this question, it's asking you if the decreasing rate is linear or exponential.

The decreasing rate would be linear, due to the fact that it is decreasing at a constant rate of 11%. The decreasing rate doesn't change, which makes this linear.

Question 2:

In this question, it's asking you what would the component's cost be in 3 years if it started off at $120.

To find this, we're going to need multiply the price by -.11, and then subtract to get the price. We would repeat this until we reach 3 years.

Question 3:

In this question, it asks if the decline in price is linear or exponential.

The decline in price would be exponential, due to the fact that the decrease in price is not always the same, since it changes every year. The price doesn't decrease at the same price each year. As you see from question 2, the change in price is not the same each year.

c. (3,2,6) is the answer.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
