Suppose you work for a packaging company and are designing a box that has a rectangular bottom with a perimeter of 36cm. The box must be 4 cm high. What dimension give the maximum value. V = l*w*h
I'll give you all 65 points that I have if you tell me how to do it because I want to understand the topic. thank you
Width of the box is the dimension which gives the gives maximum value.
Width of the box = 9 cm
Length of the box = 9 cm
Given,
The perimeter of the rectangular bottom of the box = 36 cm
The height of the box = 4 cm
We have to find the dimension which gives maximum value.
Volume = lwh
Perimeter = 2(l + w)
36 = 2l + 2w
l = (36 - 2w)/2
l = 18 - w
Now,
Volume = length × width × height
V = (18 - w) × w × 4
V = 72w - 4w²
Lets find w by using w = -b/2a
That is,
w = -72/2(-4) = -72/-8 = 9
That is,
Width of the box is 9 cm and it is the dimension which gives the maximum value.

The graph of the linear equation 4x - y = 8, with two points on the line is shown in the image attached below.
How to Graph a Linear Equation?If we know the slope, m, of the linear equation, which is the rise of the line over the run of the line, and also know the y-intercept value, b, we can graph a linear equation such that the slope of the line would be the value of m, and the point where the line intercepts the y-axis would be the value of b in the linear equation that is represented as y = mx + b.
Given the linear equation, 4x - y = 8, we can rewrite this in slope-intercept form as y = mx + b:
4x - y = 8
-y = -4x + 8 [subtraction property of equality]
y = 4x - 8 [division property of equality]
The slope, m, is 4, while the graph of the linear equation must intercept the y-axis at y = -8, because the y-intercept of the linear equation is b = -8.
Thus, the graph of 4x - y = 8 is shown below.

An architect has designed two tunnels. Tunnel A is modeled by x2 + y2 + 30x + 56 = 0, and tunnel B is modeled by x2 – 30x + 16y – 95 = 0, where all measurements are in feet. The architect wants to verify whether a truck that is 8 feet wide and 13.5 feet high can pass through the tunnels.
Part A: Write the equation for Tunnel A in standard form and determine the conic section. Show your work.
Part B: Write the equation for Tunnel B in standard form and determine the conic section. Show your work.
Part C: Determine the maximum height of each tunnel. Is the truck able to pass through either tunnel without damage? If so, which tunnel(s) and why? Show your work.
The tunnel A will be damaged and truck can pass through tunnel B.
Given that, tunnel A is modeled by x² + y² + 30x + 56 = 0, and tunnel B is modeled by x² – 30x + 16y – 95 = 0.
What is the standard form of parabola equation?The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y²= = 4ax.
Part A: x²+y²+30x+56=0
Add 15² on both the sides of a equation
That is, x²+30x+15²+y²=-56+15²
⇒ (x+15)²+y²=169
⇒ (x+15)²+y²=13²
Divide 13² on both the sides of the equation
⇒ (x+15)²/13² + y²/13² =1
Part B:
x²-30x+16y-95=0
Now, x²-30x+16y=95
Add 15² on both the sides of a equation
That is, x²-30x+15²+16y=95+15²
⇒ (x-15)²=320-16y
⇒ (x-15)²=16(20-y)
Part C:
Maximum height:
A: 13 feet
B: 20 feet
Width = 8 feet
A: x+15=8/2=4 y=12.37<13.5
B: x-15=8/2=4 y=19>13.5
Hence, the tunnel A will be damaged and truck can pass through tunnel B.

Divide both sides of the equation by 3:
[tex]\implies\dfrac{3(x^2+4)}{3}=\dfrac{0}{3}[/tex]

Solve : u² = -121
putting square root on both side
√u² = √ (-121)
u = (-11)
u = 11i
Since, there is no real square root of -121
If i is the imaginary unit then i = -1 and we find that

What is Range ?
When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.
Currently, the function is
f(x) = 7 x 4^x
Suppose,
y = f(x) = 7 x 4^x.
=> y = 7 x 4^x
Hence,
lny = ln (7 x 4^x).
We obtain using the logarithm equation
Hence,
ln y = ln7 + ln 4^x.
= ln y = ln7 + x ln4 .
Hence,
y equals e^(ln7 + x ln4).
=> y = e^ln7.e^(xln4) (xln4)
Using the exponential formula, we obtain
=> y = 7xln4
Consequently, y=f(x)=7.x.ln4
To determine function f's value (x)
7.x.ln7 = 0
As a result, For all possible values of x (x€R). To date,
=> 7x ≥ 0
=> 7xln4 ≥ 0
Therefore interval notation will be (0,∞)

<3 thx
Answer:
-6.4, -5 1/2, -5, and -2 6/4.
Step-by-step explanation:
Arranging these negative values in order from least to greatest may be tricky if you are not familiar with your integer rules and operations. However, if you seem to understand, even a little, this way may be helpful to you.
All you need to know is this. positive and negative are opposites. Thus, if, for example, +2 is greater than +1 in positives, then -2 is less than -1 in negatives. So, in other words, think about it this way when you see a negative number, but you are used to positive numbers, just assume that the biggest number on the positive side is the smallest number on the negative side.
Therefore, if we were to use this method, we would result in -6.4, -5 1/2, -5, and -2 6/4. Since it would be the opposite in positives.

The ages of Victoria and tyee are 72 and 74.
What are linear equations?A linear equation is an algebraic equation of the form y=mx+b that only contains a constant and a first-order (linear) component, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are the variables. Ax+By=C is the accepted form for two-variable linear equations. Finding both intercepts of an equation in this form is rather simple (x and y). If an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is said to be linear. The point-slope form, standard form, and slope-intercept form are the three primary types of linear equations.
As given
ages are consecutive even integers
Victoria > Tyee
So
Victoria's age = x
Tyee's age = x + 2
x(x + 2) = 80
= x² + 2x - 80
= x² + 8x - 10x - 80
Hence , the ages are 72 and 74.
