Answer:

maximum: 16minimum: -24

Step-by-step explanation:

The attache graph shows the solution region is bounded by lines through the points (-2, 4), (6, 0), and (3, -6).

The solution (x, y) = (-2, 4) gives the maximum value of z: 16.

The solution (x, y) = (3, -6) gives the minimum value of z: -24.

First, I'm going to separate factor the expression inside of the square root.

sqrt[ (2/18) * (x^5) ]

sqrt[ (1/9) * (x^5) ]

We can take the square root of 1/9 easily, because 1 and 9 are both perfect squares. The square root of 1/9 is 1/3.

Looking at the x^5, we can separate it into x^2 * x^2 * x^1. The square root of x^2 is x. So, we now also have an x^2 on the outside because there are two x^2s in our expanded form.

ANSWER: (x^2 * sqrt(x)) / 3

Use a table of values to graph the function ƒ(x) = x−−√. Choose the correct graph from the options below.

Answers

Answer:

B

Step-by-step explanation:

The square root function's graph is graph (b). This makes logical sense, because, when taking the square root (the principal root in particular), a general rule is that both the input and the output must be positive. Moreover, if one were to create a table of values to find points on the graph of the function, each of the points can be found on graph (b).

Step-by-step explanation:

You should isolate the radical, then raise each side of the equation to the power of its index.

Answer:

  d = 32

Step-by-step explanation:

Add 4, then square, and solve the resulting linear equation.

  √(7d +1) = 15

  7d +1 = 225 . . . . . . square both sides

  7d = 224 . . . . . . . . subtract 1

$1487.50

Step-by-step explanation:

9514 1404 393

Answer:

  $1487.50

Step-by-step explanation:

The amount of interest due is ...

  I = Prt

where P is the loan amount, r is the annual rate, and t is the number of years. Here, t = 6 months = 1/2 year, so the interest due is ...

  I = $1400×0.125×1/2 = $87.50

The total amount due is the sum of the loan amount and the interest:

  due = $1400 +87.50 = $1487.50

The total amount due after 60 months is $1487.50.

=FV(4.5%/12,30*12,-150,0)$113,907.92$54,000$59,907.92

Step-by-step explanation:

We have used the formula shown in Go.ogle Sheets to give the results shown. (We presume Excel has a similar function.)

The result is that the future value of the investment is $113,907.92.

The amount deposited is ($150/mo)(12 mo/yr)(30 yr) = $54,000.

The interest earned is the difference: $113,907.92 -54,000 = $59,907.92.

Boat A leaves a dock headed due east at 2:00PM traveling at a speed of 9 mi/hr. At the same time, Boat B leaves the same dock traveling due south at a speed of 15 mi/hr. Find an equation that represents the distance d in miles between the boats and any time t in hours.

Answers

Answer: [tex]17.5t[/tex]

Step-by-step explanation:

Given

Speed of boat A is [tex]v_a=9\ mi/hr[/tex]

Speed of boat B is [tex]v_b=15\ mi/hr[/tex]

Both are moving perpendicular to each other

Distance traveled by Boat A [tex]x_a=9t[/tex]

Distance traveled by Boat B [tex]x_b=15t[/tex]

Distance between them is given by Pythagoras theorem

[tex]\Rightarrow d^2=(x_a)^2+(x_b)^2\\\\\Rightarrow d^2=(9t)^2+(15t)^2\\\\\Rightarrow d=\sqrt{(9t)^2+(15t)^2}\\\\\Rightarrow d=\sqrt{81t^2+225t^2}\\\\\Rightarrow d=\sqrt{306t^2}\\\\\Rightarrow d=17.49t\approx 17.5t\ \text{miles}[/tex]

Distance between them is [tex]17.5t[/tex]

When using a regression equation, the difference between the formulas used to calculate the confidence interval estimate and prediction interval estimate is ______.

Answers

Answer:

the addition of "1" to the quantity under the radical sign.

Step-by-step explanation:

Using a regression equation :

The confidence interval is obtained using the relation :

yhat ± t(α/2) * s√(1/n + (Xp - xbar)²/SSx)

yhat = Predicted value

s = estimated standard deviation of yhat

x = Xp

The prediction interval is obtained using the relation :

yhat ± t(α/2) * s√(1 + 1/n + (Xp - xbar)²/SSx)

Hence, from the formula stated abibeb, we can see that, the only difference is the 1 added to the prediction interval formula.
