Answer:

Step-by-step explanation:

3n+2)! / (3n-3)! = (3n+2)*(3n+1)*(3n)*(3n-1)*(3n-2)*(3n-3)! divided by (3n-3)! which becomes:

23! / 18! = (23 * 22 * 21 * 20 * 19 * 18! divided by 18! which becomes:

(23 * 22 * 21 * 20 * 19)

the result is 4037880

i used my ti-84 to take 23! and divide it by 18! and i got 4037880.

this confirms the solution is correct.

What is the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2? Round your

Olegator [25]

Answer:

$0.46\pi\ radians$

Step-by-step explanation:

step 1

Find the circumference

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=5\ units$

assume

$\pi=3.14$

substitute

$C=2(3.14)(5)=31.4\ units$

step 2

Find the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2 units

Remember that

The circumference of $31.4\ units$ subtends a central angle of $2\pi \ radians$

using proportion

Let

x-----> the central angle in radians

$\frac{2\pi}{31.4}=\frac{x}{7.2} \\ \\x=2\pi (7.2)/31.4\\ \\x=0.46\pi\ radians$

If g(x) = 3x - 4, what is the value of g-^1(g(13))?

Aliun [14]

• g^-1

y = 3x – 4

3x = y + 4

x = y + 4 / 3

g^-1 = x + 4 / 3

• g(13)

3(13) – 4

39 – 4

g(13) = 35

• g^-1(g(13)) = (35) + 4 / 3

39 / 4

g^-1(g(13)) = 13

What is the solution to the equation? 1 minus z/5=9 Answers: A. z = 50 B. z = 44 C. z = –2 D. z = – 40

gtnhenbr [62]

$1 - \frac{z}{5} = 9$

add $\frac{z}{5}$ to both sides.

$1 = 9 + \frac{z}{5}$

subtract 9 to both sides.

$-8 = \frac{z}{5}$

multiply 5 to both sides.

$-40 = z$

Your answer is D) z = -40
