Answer:

slope = - $\frac{14}{3}$

Step-by-step explanation:

the slope of the secant line in the closed interval [a, b ] is

slope = $\frac{f(b)-f(a)}{b-a}$

here [a, b ] = [1, 4 ]

f(b) = f(4) = - $2^{4}$ + 5 = - 16 + 5 = - 11

f(a) = f(1) = - $2^{1}$ + 5 = - 2 + 5 = 3

slope = $\frac{-11-3}{4-1}$ = $\frac{-14}{3}$ = - $\frac{14}{3}$

a living room measures 24 feet by 15 feet an adjacent square dining room measures 13 feet on each side if carpet cost 6.98 per s

Rina8888 [55]

Start by finding how many squares in both rooms are. 24 • 15 = 360 and 13 • 4 = 52 (since it is a square room multiply by 4) Now add. 360 + 42 = 412. Now multiply : 6.98 • 412 = 2875.76. The total cost of carpet for both rooms is $2875.76. Hope I helped!
