Find the domain of the function (f/g)(x) given f (x)=x^2-4x-5 and g(x)=x^2-25

1 answer:

F + g)(x) = f(x) + g(x); (f - g)(x) = f(x) - g(x): (f · g)(x) = f(x) · g(x) ..., let f(x) = 5x+2 and g(x) = x2-1. 4. f(4)=5(4)+2=22 and g(4)=42-1=15 ... (fog)(x) = f [ g(x) ] = f [ 4x2 ] = sqrt( 4.2 ) = 2 | x |; (gof)(x) = g [f(x) ] = g [ s

Mr.Mason takes two-thirds of his body weight and drinks that amount of gatorade in ounces per day. If Mr.Mason drinks 118 ounces

denis-greek [22]

The total weight of Mason is 177

Solution:

Given that, Mr.Mason takes two-thirds of his body weight and drinks that amount of gatorade in ounces per day

Mr.Mason drinks 118 ounces each day

Let "x" be the total weight of Mr.Mason

Therefore, we can say,

Two third of body weight = Amount of gatorade drank in ounces per day

Two third of x = 118

$\frac{2}{3} \text{ of } = 118\\\\\frac{2}{3} \times x = 118\\\\2x = 118 \times 3\\\\2x = 354\\\\x = \frac{354}{2}\\\\x = 177$

Thus total weight of Mason is 177

Answer:

P = 2(2y+3)

P = 30

Step-by-step explanation:

P = 2 (L+W) or P = L + L + W + W

P = 2 (2y+3)

P = 4y+6

Plug in 6 for y.

P = 24+6

P = 30
