The options have not been given but three correct alternatives have been presented as the solution.

Answer:

3(c-2)(c-3) or3(c^2-5c+6) or 3c^2 - 15c + 18

Step-by-step explanation:

\dfrac{c^2-4}{c+3}\div\dfrac{c+2}{3(c^2-9)}

Applying the rule a^2 - b^2 = (a+b)(a-b) to the numerator of the first term and the denominator of the second term,

\dfrac{c^2-2^2}{c+3}\div\dfrac{c+2}{3(c^2-3^2)}

\dfrac{(c+2)(c-2)}{c+3}\div\dfrac{c+2}{3(c+3)(c-3)}

By changing ÷ to ×, we invert the second term

\dfrac{(c+2)(c-2)}{c+3}\times\dfrac{3(c+3)(c-3)}{c+2}

(c-2)\times3(c-3)

3(c-2)(c-3) = 3(c^2-5c+6) = 3c^2 - 15c + 18

Graph the inverse circular function by hand, given f(x) = 3sin(2x) ;-pi/4 ≤ ≤pi/4
nasty-shy [4]

Part a)

a) The given function is

f(x) = 3 \sin(2x)

We let

y =  3 \sin(2x)

Interchange x and y.

x=  3 \sin(2y)

Solve for y;

\frac{x}{3}  =  \sin(2y)

y =  \frac{1}{2}  { \sin}^{ - 1}( \frac{x}{3} )

{f}^{ - 1}(x)  =  \frac{1}{2}  { \sin}^{ - 1}( \frac{x}{3} )

Part b) The range of f(x) refers to y-values for which f(x) exists.

The range of f(x) is

-  3 \leqslant y \leqslant 3

This is because the function is within y=-3 and y=3.

c) The range of

{f}^{ - 1} (x)

is

-  \frac{ \pi}{4}  \leqslant y \leqslant  \frac{\pi}{4}

The domain is -3≤x≤3

This is because the domain and range of a function and its inverse swaps.

Part d) The graph is shown in the attachment.

Find mPRT.<br> P<br> 649U<br> 42°<br> R<br> s
Mkey [24]

Answer: 296 degrees

Step-by-step explanation:

Arc PRT is just the entire circumference - arc PT.

Since the 64 degree angle is a central angle, arc PT measures 64 degrees.

So arc PRT = 360 degree - 64 degree = 296 degrees.

teacher has 27 students in her class she asked the students to form as many groups of 4 as possible how many students are not be
stepan [7]
If there are 27 students in the class and they have to form as many groups of 4 as possible, you can calculate this using the following step: 

27 / 4 = 6.75 = 6 3/4

Result: 27 students can form 6 groups of 4 students and 3 students have to form their own group.
