Answer:
71° F
Step-by-step explanation:
Consider the rational part of f(t)
( divide numerator and denominator by t³
=
As t → infinity then → 0 , the expression simplifies to
=
= 40
Thus after driving for a long time
f(t) = 31 + 40 = 71° F
Answer:
Construction of congruent segment: First we take the measurement of the line segment with help of marked scale or a compass, then by pointing the measurements we can get the congruent line segment.
Construction of congruent angle:
Step 1: Make two congruent segments,
Step 2: Adjust compass in a fixed length.
Step 3: Make an angle on any side of one segments with help of compass,
Step 4 : Again, make an angle on any side of the another segment with the same adjusted compass.
Construction of segment bisector,
Step 1: First place the compass on the one end of the segment,
Step 2: Adjust the compass approx to the half length of the segment,
Step 3: Draw arc above and below to the segment,
Step 4: Now, go the other end and by the same length draw two arcs by crossing the previous arcs.
Step 5: join the above and below crossed marks.
Construction of angle bisector:
Step 1: Place the compass on the vertex of the angle,
Step 2: Adjust the compass in any length,
Step 3: Make an arc in one segment of the angle and from that arc again Make an arc above the angle
Step 4: Make an arc of the same length in the another segment by the same vertex and crossed the arc made above the vertex.
Step 5: join the point of crossing and the vertex of the angle.
