Answer:

Option E 15 cm

Step-by-step explanation:

we know that

The circumference of a circle subtends a central angle of 360 degrees

using proportion

Find out the length of arc DE by a central angle of 45 degrees

Let

x -----> the length of arc DE

$\frac{120}{360}=\frac{x}{45}\\\\x=120*45/360\\\\x=15\ cm$

Create a 3rd degree polynomial function with one zero at three. Sketch a graph

DedPeter [7]

Answer:

$f(x) = {x}^{3} - 9 {x}^{2} + 27x - 27$

Step-by-step explanation:

We want to create a third degree polynomial function with one zero at three.

In other words, we want to find a polynomial function with roots x=3 , multiplicity, 3.

Since x=3 is a solution, x-3 is the only factor that repeats thrice.

$f(x) = {(x - 3)}^{3}$

We expand to get:

$f(x) = x( {x}^{2} - 6x + 9) - 3( {x}^{2} - 6x + 9)$

$f(x) = {x}^{3} - 6 {x}^{2} + 9x- 3 {x}^{2} + 18x - 27$

This simplifies to:

$f(x) = {x}^{3} - 9 {x}^{2} + 27x - 27$

What is the solution to w - 9 1/2 = 15 24 1/2 6 1/2 23 1/2 5 1/2

VladimirAG [237]

Answer:

Option A

Step-by-step explanation:

Convert mixed fraction to improper fraction.

$\sf w - 9\dfrac{1}{2}=15\\\\ w - \dfrac{19}{2}=15$

Now isolate 'w'

$\sf w = 15 +\dfrac{19}{2}\\\\= \dfrac{15*2}{1*2}+\dfrac{19}{2}\\\\=\dfrac{30}{2}+\dfrac{19}{2}\\\\=\dfrac{30+19}{2}\\\\=\dfrac{49}{2}\\\\= 24\dfrac{1}{2}$

Solve 5x - c = k for x Answers above

Rama09 [41]

Answer:

x = ( k+c)/5

Step-by-step explanation:

5x - c = k

Add c to each side

5x -c+c = k+c

5x = k+c

Divide by 5

5x/5= ( k+c)/5

x = ( k+c)/5
