Answer:
Option D is correct
QP = 20 units
Step-by-step explanation:
From the given figure we have;
QP = n units, PN = 11.5 units and NM = 24 units
Using tangent secant formula we have;
First find PM:
PM = PN+NM
PM = 11.5 + 24 = 35.5 units
Substitute the given values we have;
⇒
⇒ units
Therefore, the length of the line segment QP to the nearest unit is, 20 units

Answer:
.
Step-by-step explanation:
We have been given that 4 days I have 140 copies of a book, 9 days I only have 50 left. We are asked to write an equation , where c is number of copies still on hand and t days being available.
We have two points on line (4,140) and (9,50). Now, we will use these points to find slope as:
Now, we will use point-slope form of equation and substitute
and coordinates of point (9,50) as:
Therefore, our required equation would be .
