Find the value for y. Geometry!! pls help!! thank youuuu
bulgar [2K]

Answer:

2

Step-by-step explanation:

By the triangle proportionality theorem,

\frac{12}{2y  - 1}  =  \frac{4y - 4}{1}  \\  \\ 12 = (2y - 1)(4y - 4) \\  \\ 12 = 8 {y}^{2}  - 12y + 4 \\  \\ 8 {y}^{2}  - 12y - 8 =0 \\  \\2 {y}^{2}  - 3 y - 2 = 0 \\  \\ (2y + 1)(y - 2) = 0

From this, we know that y = -1/2 or 2.

However, as distance must be positive, we disregard the negative case, giving us y = 2.

i) The given function is

f(x)=\frac{x-5}{2x^2-5x-3}

The factored form is

f(x)=\frac{x-5}{(x-3)(2x+1)}

The domain are the values of  x for which the function is defined.

(x-3)(2x+1)\ne 0

(x-3)\ne0,(2x+1)\ne 0

x\ne3,x\ne-\frac{1}{2}

ii) To find the vertical asymptotes, equate the denominator to zero.

(x-3)(2x+1)=0

(x-3)=\ne0,(2x+1)=0

x=3,x=-\frac{1}{2}

iii) To find the roots, equate the numerator to zero.

x-5=0

The root is x=5

iv) To find the y-intercept, put x=0 into the function.

f(0)=\frac{0-5}{(0-3)(2(0)+1)}

f(0)=\frac{-5}{(-3)(1)}

f(0)=\frac{5}{3}

The y-intercept is \frac{5}{3}

v) The horizontal asymptote is given by;

lim_{x\to \infty}\frac{x-5}{2x^2-5x-3}=0

The horizontal asymptote is y=0

vi) The function is not reducible. There are no holes.

vii) The given function is a proper rational function.

Proper rational functions do not have oblique asymptotes.

If 800,000 was rounded to the nearest hundred thousand what is the largest number
vfiekz [6]

The largest number of people that could have attended the event would be 849,999. If it was 850,000 it would be rounded up to 900,000.

The smallest number of people that could have attended would be 750,000. If there was 749,999, it would be rounded down to 700,000.

Hope this helps!
