you want to frame a collage of picture with a 9ft strip of wood. What dimensions will help you maximize the area?
Answer:
Suppose you want to frame a collage of pictures. You have a 9-ft strip of wood for the frame. What dimensions of the frame give you the maximum area for the collage? What is the maximum area?
A:
Perimeter = 2(L + W) 9 = 2(L+W) L+W = 4.5 L = 4.5-W Area = LW Area = (4.5-W)W A = 4.5W - W^2 You have a quadratic with a = -1 and b = 4.5 Maximum area occurs when W = -b/(2a) = 4.5/(2*-1) = 2.25
Step-by-step explanation:
Dimension of the picture with 9ft strip of wood is
length = 2.25 ft and width =2.25 ft
Given :
you want to frame a collage of picture with a 9ft strip of wood.
the perimeter of the frame is 9 ft
Perimeter of rectangle = 2(length +width )
Let 'l' be the length and 'w' be the width
[tex]Perimeter =2(l+w)\\9=2(l+w)\\Divide \; by \; 2\\l+w=4.5\\l=4.5-w[/tex]
Now we find the area
[tex]Area = length \cdot width \\Area= l \cdot w\\A= (4.5-w)(w)\\A=-w^2+4.5w[/tex]
Now we find out 'w' where area is maximum
[tex]w=-\frac{b}{2a} \\a=-1 and b=4.5\\w=-\frac{4.5}{2(-1)} =2.25[/tex]
Width =2.25 gives us maximum area
Now find out the length ,
[tex]Length = 4.5 -w\\w=2.25\\Length = 4.5-2.25=2.25[/tex]
Dimension of the picture is length = 2.25 ft and width =2.25 ft

Which equation represents the vertex form of the equation y = x2 + 2x - 6?
Answer:
y=(x+1)^2-7
Step-by-step explanation:
y=x^2+2x-6=x^2+2x+1-7
y=(x^2+2*1*x+1^2)-7
y=(x+1)^2-7
vertex form equation is y=a(x-h)^2+k
of equation y=ax^2+by+c
so a is 1
h is -1 because (x+1)=(x-(-1))
k is -7
which table has a constant of proportionality between Y and X of 1/5?
Answer:
B
Step-by-step explanation:
From the table B has a constant of proportionality between y and x of 1/5.
We need to find which table has a constant of proportionality between y and x of 1/5.
What is constant of proportionality?Constant of proportionality is the constant value of the ratio between two proportional quantities.
The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate.
Now, k=y/x
From table A:
k=4/5 ÷ 2
=2/5
k=14/5 ÷ 7
=2/5
k=24/5 ÷ 12
=2/5
From table B:
k=8/5 ÷ 8
=1/5
k=9/5 ÷ 9
=1/5
k=2/10 =1/5
From table C:
k=16/5 ÷ 3
=16/15
k=26/5 ÷ 5
=26/25
k=36/5 ÷ 7
=36/35
Therefore, from the table B has a constant of proportionality between y and x of 1/5.

Find three consecutive odd integers such that the sum of the first and the third is 70. Find the integers.
Answer:
33, 35, 37
Step-by-step explanation:
Let the tree consecutive odd integers be x, x +2 and x + 4
According to the given information:
Sum of the first and the third is 70
[tex] \therefore x + x + 4 = 70\\\\
\therefore 2x = 70 - 4\\\\
\therefore 2x = 66\\\\
\therefore x = \frac{66}{2}\\\\
\therefore x = 33\\\\
\implies x + 2 = 33 + 2 = 35\\\\
\& \hspace{25 pt}x + 4 = 33 + 4 = 37\\\\[/tex]
Thus, the three consecutive odd integers are 33, 35 and 37.

,
x

Work out
x
when
y
=
20
Answer:
x = 5
Step-by-step explanation:
Given that y is inversely proportional to x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportion
To find k use the condition when y = 25 , x = 4 , then
25 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
100 = k
y = [tex]\frac{100}{x}[/tex] ← equation of proportion
When y = 20, then
20 = [tex]\frac{100}{x}[/tex] ( multiply both sides by x )
20x = 100 ( divide both sides by 20 )
x = 5

The volume of a circular cylinder is calculated using the formula
Answer:
6%
Step-by-step explanation:
Since the volume of the cylinder V = πr²h where r = radius of cylinder and h = height of cylinder and h = 2r, we have that r = h/2.
Substituting r into v, we have
V = πr²h
V = π(h/2)²h
V = πh³/4
Now let ΔV be the error in the volume and Δh be the error in the height.
Since h is raised to the power of 3,
ΔV/V = 3Δh/h
multiplying both sides by 100, we have
ΔV/V × 100 = 3Δh/h × 100
So, we have
ΔV/V × 100 = 3 × Δh/h × 100
since Δh/h × 100 = percentage error in height = 2%, and ΔV/V × 100 = percentage error in volume,
ΔV/V × 100 = 3 × 2% = 6%
So, the percentage error in volume is 6 %

Let event A = The student plays basketball.
Let event B = The student plays soccer.
What is PlA or B)?
The probability P(A or B) is equal to 5/10 = 0.5
How to find the probability?
P(A or B) is the probability that a randomly selected student plays either basketball of soccer.
On the diagram, we can see that there are a total of 10 students, such that 2 play only basketball and 3 play only soccer.
P(A or B) is equal to the quotient between the number of students that play one of the sports (here we don't count the ones that play both sports) and the total number of students.
Then we have:
P(A or B) = (2 + 3)/10 = 0.5
