1) area of a cicular pool
area of a circle=πr^2 d=2.5 then r=2.5/2
A=3.14 *(2.5/2)^2
A=4.906m^2 A=4.9m^2

2) arae of a coin
<span>(if i read it right d=15mm?)
</span>A=πr^2 d=15 then r=15/2
A=3.14*(15/2)^2 =176.6mm^2

Rest all are same problems u try to solve it

Ava wants to figure out the average speed she is driving. She starts checking her car’s clock at mile marker 0. It takes her 4 m

olga_2 [115]

The average speed is obtained by finding the slope of the function in the given interval:

$v =\frac{y2-y1}{x2-x1}$

Substituting values we have:

$v =\frac{6-3}{8-4}$

Rewriting:

$v =\frac{3}{4}$

$v = 0.75$

Then, the generic equation of the line is:

$n-n0 = v (t-t0)$

Where,

v: average speed (slope of the line)

(t0, n0): ordered pair that belongs to the line.

Substituting values we have:

$n-6 = 0.75 (t-8)$

Answer:

the average speed of the car is:

b. 0.75

an equation of the line is:

b. n-6= 0.75(t-8)
