PERT = \frac{OT+4MLT+PT}{6}

Activity B: OT = 3, MLT = 6, PT = 12

PERT = \frac{3+4(6)+12}{6}

         = \frac{3+24+12}{6}

         = \frac{39}{6}

         = 6.5

1. The Fold-N-Go box factory makes boxes that hold 1 candle. The boxes measure 1 3 1 3 9 inches.
svet-max [94.6K]

Answer:

1. 360 cubic inches

2.(a)360 Cubic Inches, the owner is wrong

(b)6 in X 1 in X 1 in.

Step-by-step explanation:

1. Dimension of the box

Length=9 inch

Width=1 inch

Height=1 inch

Volume=LWH

=9*1*1 =9 Cubic Inches

Volume of the stack( of 40 candles)

=40*9

=360 Cubic Inches

2. Dimensions of Ella' Box are:

Length=10 inch

Width=6 inch

Height=6 inch

Volume=LWH

=10*6*6

=360 Cubic Inches

(a)The owner is not correct. The Volume of Ella's box is equal to the volume of the stack.

(b)Since the Width of the box is 6 Inch, the owner could cut the boxes into dimensions of 6 inX1 inx1 in.

It means each level will contain

(6*10) candles.

There will be 6 layers which equals the exact volume of Ella's box.

The table represents a linear function. The rate of change between the points (–5, 10) and (–4, 5) is –5. What is the rate of ch
vladimir1956 [14]
<h2>Answer:</h2>

The rate of change between the points (–3, 0) and (–2, –5) is:

                          -5

<h2>Step-by-step explanation:</h2>

The rate of change between the points (-5, 10) and (-4, 5) is -5.

Now we are asked to find the average rate of change between (-3,0) and (-2,-5)

We know that the average rate of change between two points (a,b) and (c,d) is calculated by the formula:

  Rate\ of\ change=\dfrac{d-b}{c-a}

Here we have:

(a,b)=(-3,0) and (c,d)=(-2,-5)

Hence, the average rate of change is:

 Rate\ of\ change=\dfrac{-5-0}{-2-(-3)}\\\\\\Rate\ of\ change=\dfrac{-5}{-2+3}\\\\\\Rate\ of\ change=-5

Also, we know that for any linear function the average rate of change is same between any two points.

           Hence, the answer is:

                        -5

i) The given function is

f(x)=\frac{x-5}{2x^2-5x-3}

The factored form is

f(x)=\frac{x-5}{(x-3)(2x+1)}

The domain are the values of  x for which the function is defined.

(x-3)(2x+1)\ne 0

(x-3)\ne0,(2x+1)\ne 0

x\ne3,x\ne-\frac{1}{2}

ii) To find the vertical asymptotes, equate the denominator to zero.

(x-3)(2x+1)=0

(x-3)=\ne0,(2x+1)=0

x=3,x=-\frac{1}{2}

iii) To find the roots, equate the numerator to zero.

x-5=0

The root is x=5

iv) To find the y-intercept, put x=0 into the function.

f(0)=\frac{0-5}{(0-3)(2(0)+1)}

f(0)=\frac{-5}{(-3)(1)}

f(0)=\frac{5}{3}

The y-intercept is \frac{5}{3}

v) The horizontal asymptote is given by;

lim_{x\to \infty}\frac{x-5}{2x^2-5x-3}=0

The horizontal asymptote is y=0

vi) The function is not reducible. There are no holes.

vii) The given function is a proper rational function.

Proper rational functions do not have oblique asymptotes.
