Answer:

The answer is "789.03 and 806.16".

Step-by-step explanation:

$y\^ \ \ = -0.45 + 3.78(x) -11.88(d_1) + 5.25(d_2)$

For point a:

Calculating the value for $y\^ \ \ x = 212,\ \ d_1 = 1, and \ \ d_2 = 0$

$y\^ = -0.45 + 3.78(212) -11.88(1) + 5.25(0)$

$= -0.45 + 801.36 -11.88 + 0\\\\= 789.03$

For point b:

Calculating the value of $y\^ \ \ for \ \ x = 212, \ \ d_1 = 0, and \ \ d_2 = 1$

$y\^ = -0.45 + 3.78(212) -11.88(0) + 5.25(1)$

$= -0.45 + 801.36 -0 + 5.25\\\\= 806.16$

A rectangular pool 6 meters by 4 meters is surrounded by a walkway of width x meters. At what value of x will the area of the wa

steposvetlana [31]

Answer:

x=1 meter

Step-by-step explanation:

step 1

Find the area of the rectangular pool

$A=LW$

we have

$L=6\ m\\W=4\ m$

substitute

$A=6(4)=24\ m^2$

step 2

Find the area of rectangular pool including the area of the walkway

Let

x ----> the width of the walkway

we have

$L=(6+2x)\ m\\W=(4+2x)\ m$

substitute

$A=(6+2x)(4+2x)$

step 3

Find the area of the walkway

To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway

$A=(6+2x)(4+2x)-24$

step 4

Find the value of x if the area of the walkway equal the area of the pool

$(6+2x)(4+2x)-24=24$

Solve the quadratic equation by graphing

The solution is x=1 meter

see the attached figure
