Answer:

perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th

Step-by-step explanation:

The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π

Both semicircles together have a length of 5π + 5π = 10π

The radius of the 1/4 circle is 10, so the diameter is 20

The length of the 1/4 circle's arc is 1/4 times the circumference of its circle

So, the length of that arc is 1/4π(20) = 5π

Now the perimeter of the fountain is 10π + 5π = 15π

Determine whether the polynomial below can be factored into perfect squares. If so, factor the polynomial. Otherwise, select tha

Natasha2012 [34]

Answer:

C. $(4x-8)^2$

Step-by-step explanation:

We need to determine whether the given polynomial $16x^2-64x+64$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

$16x^2-64x+64$

$=16x^2-32x-32x+64$

$=16x(x-2)-32(x-2)$

$=(16x-32)(x-2)$

$=16(x-2)(x-2)$

$=16(x-2)^2$

$=4^2(x-2)^2$

$=(4(x-2))^2$

$=(4x-8)^2$

Hence final answe is choic C. $(4x-8)^2$

Point F is on line segment \overline{EG} EG . Given FG=8,FG=8, EF=2x+4,EF=2x+4, and EG=4x-10,EG=4x−10, determine the numerical l

Leokris [45]

Answer:

26 units

Step-by-step explanation:

If point F is on the line segment EG, then EF+FG = EG

Given

FG=8,

EF=2x+4

EG=4x−10

Substitute the given values into the formula;

2x+4+8 = 4x−10

2x+12 = 4x-10

collect like terms

2x-4x = -10-12

-2x = -22

x = 22/2

x =11

Since EF = 2x+4

EF = 2(11)+4

EF = 22+4

EF = 26

Hence the numerical length of EF is 26 units
