Data for coronavirus infections for Spain is shown below. Number of days since first infection reported Total number of infections 0 1 10 2 20 2 30 83 40 2140 45 9191 47 13,716 1. Which type of model fits this data best? 2. Enter the function that models the data. 3. If this rate continues how many total infections should there be by day 75? 4. After how many days would there be 20,000,000 infections?

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.

answer: 0.26
