Let x, y, and z denote the side lengths of the box, with the bottom face having dimensions x-by-y and z is the height. Naturally this means each of x, y, and z must be greater than 0.

The box has a fixed volume of 252 cm³, so

xyz = 252

The surface area of the box is

2xy + 2xz + 2yz

and we're told that the material cost for each face is different. The total cost of the material needed to make the box is given by

C (x, y, z) = ($5/cm²) xy + ($2/cm²) xy + 2 ($3/cm²) (xz + yz)

or, omitting units and simplifying,

C (x, y, z) = 7xy + 6 (x + y) z

In the volume constraint, solve for any one variable; I'll do z.

z = 252/(xy)

Substitute this into the cost function:

C (x, y, 252/(xy)) = 7xy + 1512 (x + y)/(xy)

Since this is now a function of 2 variables, I'll rewrite this as

C* (x, y) = 7xy + 1512 (1/y + 1/x)

Compute the partial derivatives of C and find the critical points:

∂C/∂x = 7y - 1512/x² = 0   ⇒   x² y = 216

∂C/∂y = 7x - 1512/y² = 0   ⇒   x y² = 216

It follows that

x² y = x y²   ⇒   x = y

Just like before, we can think about C* as yet another function but only of 1 variable,

C** (x) = 7x² + 3024/x

Now find the critical points of C** :

dC**/dx = 14x - 3024/x² = 0   ⇒   x = 6

All of this tells us that C (x, y, z) has a critical point when x = y = 6 and z = 252/6² = 7. So the box that costs the least has dimensions 6 × 6 × 7 cm, which gives the box a surface area of 240 cm² and a total cost of $756.

1. Marlene is going on a camping trip with a group of friends. She brings 3 boxes of granola bars,
plus 3 extra bars. Robyn bring 2 boxes of granola bars and Wendy brings one box. They have a
total of 57 granola bars. If each box contains the same number of bars, how many bars are in
each box?

Answers

Answer:

13.5

Step-by-step explanation:

total boxes of granola is = 3 + 2 + 1

                                         =  6 boxes

6 boxes = 57 bars

1 box  =  57 / 6

1 box  = 9.5 + 3

           = 13.5 (ANS)

i hope my ans is correct if not i apologise.

The answer is 9.
Marlene brought 3 boxes AND 3 extra bars so you would have to subtract those from the total before dividing.

57-3=54
54/6=9

Answer:

a) (2x + 1)(3x - 4)

b) 546

Step-by-step explanation:

a)

We need to try to factor the polynomial.

6(-4) = -24

6x² - 8x + 3x - 4 = 2x(3x - 4) + 1(3x - 4) =

= (2x + 1)(3x - 4)

b)

6(10)² - 5(10) - 4 = 600 - 50 - 4 = 546

Answer:

(a) when x = 2:    width = 2 units   and     length = 5 units

(b) 546 units²

Step-by-step explanation:

Given expression:

[tex]6x^2-5x-4[/tex]

Part (a)

To factor a quadratic in the form [tex]ax^2+bx+c[/tex]

Find 2 two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]

Two numbers that multiply to -24 and sum to -5:  -8 and 3

Rewrite [tex]b[/tex] as the sum of these 2 numbers:

[tex]\implies 6x^2+3x-8x-4[/tex]

Factorize the first two terms and the last two terms separately:

[tex]\implies 3x(2x+1)-4(2x+1)[/tex]

Factor out the common term [tex](2x+1)[/tex]:

[tex]\implies (3x-4)(2x+1)[/tex]

Therefore:

[tex]\implies x=\dfrac{4}{3}, \: x=-\dfrac{1}{2}[/tex]

As distance is positive, [tex]x > \dfrac{4}{3}[/tex]

Let [tex]x=2[/tex]

[tex]\implies (3(2)-4)(2(2)+1)[/tex]

[tex]\implies (2)(5)[/tex]

Therefore, possible dimensions of the rectangle are:

width = 2 units

length = 5 units

Part (b)

Substitute [tex]x=10[/tex] into the equation:

[tex]\begin{aligned}\implies 6(10)^2-5(10)-4&=600-50-4\\&=546\end{aligned}[/tex]

if two angles in a triangle are 50 and 40, it must be a/an___________________triangle.

Answers

Answer:

right triangle

Step-by-step explanation:

Hey there!

A triangle has to have three vertices that add up to 180 degrees

The angle measurments 50 and 40 are already given and added up, they equal 90 degrees

Now out of 180 degrees, 90 degrees is already shown

What you need to do now is try to find how much more degrees you need to get 180 degrees

As you know 180-90=90

So this means that the missing angle is 90 degrees

Now that we know this, we can find out what type of triangle this is

Since the triangle has an angle that is equal to 90 degrees, or it has a right angle, the triangle can be called a right triangle

A right triangle is a triangle that has an angle that is equal to 90 degrees

So this triangle is a right triangle

calculate the shaded area

Answers

Answer:

42 cm²

Step-by-step explanation:

the length of the shaded area is the length of the white rectangle, that is

length = 7 cm

the width of the blue area is the length of the white rectangle subtract twice the width of the white rectangle, that is

width = 7 - (2 × 0.5) = 7 - 1 = 6 cm

shaded area = length × width = 7 × 6 = 42 cm²

Write the equation
for this line in
slope-intercept form.

y = ?/?x+ ?

Answers

Answer:

y = 2/3x - 1 (or y = 2/3x + -1 to fit the graphic)

Step-by-step explanation:

Slope intercept form is written as (y = mx + b) where m is slope and b is the y intercept.

First you need to find the slope, m. We'll use the two points (-3, -3) and (3, 1)

m = (y2 - y1) / (x2 - x1)

m = (1 - (-3)) / (3 - (-3))

m = 4/6

m = 2/3

Next we need the y intercept, b. On the graph we can see that is -1 but we can also find it substituting the known slope and one point on the line for our values to solve for b. We'll use (3, 1) as the point.

y = mx + b

1 = 2/3 * 3 + b

simplify 2/3 * 3

1 = 2 + b

subtract 2 from both sides

-1 = b

Now we have all the values we need to plug into our slope intercept equation (m = 2/3, b = -1)

y = mx + b

y = 2/3x - 1

Answer:

[tex]\sf{y=\displaystyle\frac{2}{3} x-1[/tex]

Solution:We are given two points: (3, 1) and (-3, -3).We can use these points to find the slope of the line:m=[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex][tex]\displaystyle\frac{-3-1}{-3-3} =\frac{-4}{-6} =\frac{2}{3} \longleftarrow\sf{slope}[/tex]Now, we need to identify the line's y-intercept.The y-intercept is the point where the graph touches the y-axis.Since the graph touches the y-axis at (0, -1) the y-intercept is equivalent to (0, -1) or -1.

Hope it helps.
