A contractor is in charge of hiring people for a construction project. The number of days it would take to complete the project
sweet-ann [11.9K]

Answer:

\text{Domain of x}=[1,\infty), x \in Z^+

Step-by-step explanation:

Given the function: f(x)=\dfrac{280}{x},$ where:

f(x) =number of days it would take to complete the project

x =number of full-time workers.

\text{When x=0, }f(x)=\dfrac{280}{0}=$Undetermined\\\text{When x=1, }f(x)=\dfrac{280}{1}=$280 days\\\text{When x=280, }f(x)=\dfrac{280}{280}=$1 day\\\text{When x=560, }f(x)=\dfrac{280}{560}=$0.5 days

The domain of a function is the complete set of possible values of the independent variable.

In this case, the independent variable is x, the number of full-time workers. We have shown that x cannot be zero as there must be at least a worker on ground.

Therefore, an appropriate domain of the function f(x) is the set of positive integers (from 1 to infinity).

\text{Domain of x}=[1,\infty), x \in Z^+

Find the distance between the points (-2,3) and (3,-9)
kakasveta [241]

Answer:

  13 units

Step-by-step explanation:

Put the numbers in the distance formula and do the arithmetic.

  d = √((x2 -x1)² +(y2 -y1)²)

  = √((3 -(-2))² +(-9-3)²) = √(5² +(-12)²) = √(25 +144)

  d = √169 = 13

The distance between the points is 13 units.

IceJOKER [234]
Hey there 

350/100 as a decimal.  
To make fraction into decimal you divide the numerator by the denominator. 
 
350/100
350÷ 100 =3.5

350/100 as a decimal is 3.5

TO convert to percent you have to multiply decimal by 100. 

3.5 x 100 = 350
350 is the percent
