Answer:

$2.50$

Step-by-step explanation:

Given

$(x_1,y_1) = (-1,0.8)$

$(x_2,y_2) = (0,2)$

$(x_3,y_3) = (1,5)$

$(x_4,y_4) = (2,12.5)$

Required

The rate of change (b)

The above graph is represented as:

$y = ab^x$

For: $(x_2,y_2) = (0,2)$ ;

We have:

$y = ab^x$

$2 = a * b^0$

$2 = a *1$

$2 = a$

$a = 2$

For $(x_3,y_3) = (1,5)$ ,

We have:

$y = ab^x$

$5 = a * b^1$

$5 = a * b$

Substitute $a = 2$

$5 = 2 * b$

Divide by 2

$2.5 = b$

$b = 2.5$

<em>Hence, the rate of change is 2.50</em>

*PLEASE ANSWER TY* What is the area of minor sector DFE?

FinnZ [79.3K]

Answer:

x ≈ 34.88 square cm

Step-by-step explanation:

Solve by proportional formula:

Area of a sector/area of circle* = sector central arc measure/360

*area of a circle = πr²

x/(53.29π) = 75/360

x/53.29π = 0.2083

x = 11.1020833π

x = 34.8782233

x ≈ 34.88 square cm
