Let gbe a function such that g(x) = -2r + 5 and is defined on the domain (-1,3) State the range of this function in interval not

Paladinen [302]

Answer:

The range interval is: (7, -1)

Step-by-step explanation:

Given the function

g(x) = -2r+5

As the domain is (-1, 3)

Let us put the domain values in the interval (-1, 3)

Putting x = -1

g(x)=-2r+5

= -2(-1)+5

= 2+5

= 7

Putting x = 0

g(x)=-2r+5

= -2(0)+5

=0+5

= 5

Putting x = 1

g(x)=-2r+5

= -2(1)+5

=-2+5

= 3

Putting x = 2

g(x)=-2r+5

= -2(2)+5

=-4+5

= 1

Putting x = 3

g(x)=-2r+5

= -2(3)+5

=-6+5

= -1

Thus the range interval is: (7, -1)

Can I get some help on how to solve this?

Klio2033 [76]

Answer:

see explanation

Step-by-step explanation:

Factorise both denominators

x² + 2x = x(x + 2) ← common factor of x

x² - 4 = (x - 2)(x + 2) ← difference of squares

Before subtracting we require common denominators

Multiply the numerator/denominator of the first fraction by (x - 2)

Multiply the numerator of the second fraction by x

= $\frac{5}{x(x-2)(x+2)}$ - $\frac{2x}{x(x-2)(x+2)}$

Distribute and simplify the numerator leaving the denominator

= $\frac{5x-10-2x}{x(x-2)(x+2)}$

= $\frac{3x-10}{x(x-2)(x+2)}$

Degrees: $s = \frac{\pi}{180}\theta r$
   $s = \frac{\pi}{180}(\frac{s}{r})(r)$
  <span> $s = \frac{\pi}{180}(\frac{165}{4})(4)$
  </span> $s = \frac{\pi}{180}(41.25)(4)$
   $s = \frac{\pi}{180}(165)$
   $s = \frac{165\pi}{180}$
   $s = \frac{11\pi}{12}$
   $s = \frac{11\pi}{12} * \frac{180}{\pi}$
   $s = 11 * 15$
   $s = 165\°$

Radians: $s = \theta r$
$s = \frac{s}{r}(r)$
$s = \frac{165}{4}(4)$
$s =41.25(4)$
$s =165$
$s =165 * \frac{\pi}{180}$
$s =11 * \frac{\pi}{12}$
$s = \frac{11\pi}{12}$

$Arc\ Length = \frac{central\ angle}{360} * circumference$
$Arc\ Length = \frac{\theta}{360} * 2\pi r$
$Arc\ Length = \frac{165}{360} * 2(3.14)(4)$
$Arc\ Length = \frac{11}{24} * 2(12.56)$
$Arc\ Length = \frac{11}{24} * 25.12$
$Arc\ Length = \frac{276.32}{24}$
$Arc\ Length \approx 11.51\bar{3}$

The answer is A.
