Answer:

<u>Option 3: 0 ≤ x ≤ ∞ </u>

Step-by-step explanation:

The domain of a function is the set of all possible x values for the function.

The given function is y = √x

The domain for the square root function should be : x ≥ 0

So, the domain = [0,∞)

Or, it can be written as inequality

So, 0 ≤ x ≤ ∞

So, the answer is option 3.

Which employee's path is the critical path on this activity graph? Explain how you know that this employee's path is the critica

Natali5045456 [20]

Answer:

Jim's path is the critical path on this activity graph.

Step-by-step explanation:

Critical Path:

Critical path is the the longest path in the project task paths. It shows the least amount of time in which project can be completed. It can be find by looking at the longest path in the network diagram of the project; not in term of nodes or activities instead in term of days.

In given case:

Path 1 Bill task's total duration= 6 days

Path 2 Jim's task's total duration= 17 days

Path 3 Betty task's total duration= 7 days

Path 4 Cynthia task's total duration= 14 days

Hence the longest path i.e. critical path is of Jim's activity path !

Need help with number 26, multi-step!!

Rufina [12.5K]

Answer:

$204.11

Step-by-step explanation:

He is paying 70% of the original cost, so he is paying

269.99(0.7) = $188.99

He has to pay 8% sales tax on that discount price, so he pays

$188.99(0.08) = $15.12 tax

for a total of

$188.99 + $15.12 = $204.11

35. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.

Montano1993 [528]

Answer:

The linear equation for the line which passes through the points given as (-2,8) and $(4,6), is written in the point-slope form as $y=-\frac{1}{3} x-\frac{26}{3}$ .

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (-2,8) and (4,6).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 3

Determine the slope of the line.

The points through which the line passes are given as (-2,8) and (4,6). Next, the formula for the slope is given as,

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute $6 \& 8$ for $y_{2}$ and $y_{1}$ respectively, and 4&-2 for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows, $m=\frac{6-8}{4-(-2)}$

$\begin{aligned}&m=\frac{-2}{6} \\&m=-\frac{1}{3}\end{aligned}$

Step 2 of 3

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

$y-y_{1}=m\left(x-x_{1}\right)$

Substitute $-\frac{1}{3}$ for m,-2 for $x_{1}$ , and 8 for $y_{1}$ in the above equation and simplify using the distributive property as follows, $y-8=-\frac{1}{3}(x-(-2))$\\ $y-8=-\frac{1}{3}(x+2)$\\ $y-8=-\frac{1}{3} x-\frac{2}{3}$$
