If Pls the point $$(15,1020)$$ or the grape of $$V$$, find the elopes of the secant lines $$P0$$ when $$Q$$ h the point on the orath wath the folloning values. $$\begin{array}{c}Q\\ (5,272)\\ (10,176)\\ (20,440)\\ (25,109)\\ (30,0)\end{array}$$ $$\mathrm{sinc}1$$ Stopes of secant lines passing through $$\{(15,1020)$$ and $$(c,4,1(c))$$ can be cilculated using $$m_{10}=\frac{v(t)?1020}{t?15}$$ We begin by cakculating the slope when $$e+5$$. $$m\text{ mes }\frac{(v(5)?1020}{5?15}$$ Estimate the slope of the tangent line at $$P(15,1020)$$ by averaging the slopes of two adjacent secant lines. Step 1 Looking at the table, the t-values adjacent to $$t=15$$ are $$\begin{array}{ll}t=& \text{ (smaller value) }\\ t=& \text{ (larger value). }\end{array}$$
