borishaifa [10]

Answer:

<h2>30page essay/min</h2>

Step-by-step explanation:

Speed is the change in distance of a body with respect to time.

Speed = Distance/Time

If the library made a copy of leslie's 3 page essay in just 1/10 of a minute, this means that she made 3 pages in (1/10 * 60)secs i.e 6secs

To get the speed, we need to calculate the amount of page of essay that are produced in a minute (60secs).

If 3 page essay = 6secs

x page essay = 60 secs

cross multiply

3*60 = 6x

180 = 6x

x = 180/6

x = 30

This shows that 30 page essays are produced in just a minute. Hence the speed of the copy machine is 30page essay/min.

Determine the domain of the function (f*g)(x) where f(x) =3x-1/x-4 and g(x) =x+1/x

BARSIC [14]

Answer:

Domain = R- {0,4}

Step-by-step explanation:

$f(x) =\frac{3x-1}{x-4}$

$g(x) =\frac{x+1}{x}$

$(f*g)(x)=\frac{3x-1}{x-4} \times \frac{x+1}{x}$

$(f*g)(x)=\frac{(3x-1)(x+1)}{(x-4)(x)}$

In order to function (f*g)x to be defined , the Denominator must not be equal to zero.

Hence

x ≠ 0

(x-4) ≠ 0 ⇒ x≠4

Hence (f*g)x is defined for all values of x except 0 and 4

Hence Domain = R- {0,4}

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-2, -5)

Point (3, -6)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(3--2)^2+(-6--5)^2}$
(Parenthesis) Simplify: $\displaystyle d = \sqrt{(3+2)^2+(-6+5)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(5)^2+(-1)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{25+1}$
[√Radical] Add: $\displaystyle d = \sqrt{26}$
