The value of the length of BC is 45 units

<h3>How to determine the length BC?</h3>

The given parameters are:

BC = 15x

AD = 32x - 2

EF = 20.5x + 8

Where the parallel bases are AD and BC and the midsegment is EF

By the midsegment theorem, we have

2 * EF = AD + BC

Substitute the known values in the above equation

2 * (20.5x + 8) = 15x + 32x -2

Open the bracket

41x + 16 = 15x + 32x - 2

Evaluate the like terms

6x = 18

Divide both sides by 6

x = 3

Substitute x = 3 in BC = 15x

BC = 15 * 3

Evaluate

BC = 45

Hence, the value of the length of BC is 45 units

Zolol [24]

Answer:

The function f(x) was translated right 3 units and up 2 units.

Step-by-step explanation:

F(x)=(2/3)^x

If we move it right for 3 units, we get

f(x)= (2/3)^(x-3)

If we move up 2 units , we get

g(x)= (2/3)^(x-3) +2

A circle has a circumference of 44m. What
MakcuM [25]
<h3>Answer: B. 154 square meters</h3>

================================

Work Shown:

C = 44 is the circumference

in general, the circumference of a circle is

C = 2*pi*r

Plug in C = 44 and solve for r.

C = 2*pi*r

44 = 2*pi*r

2*pi*r = 44

r = 44/(2pi)

r = 7.0028175 which is approximate

--------------------

Now plug this into the formula for the area of a circle

A = pi*r^2

A = pi*(7.0028175)^2

A = 154.061985

A = 154 rounding to the nearest whole number
