The sum of the base and the height of a triangle is 22 cm. Find the dimensions for which the area is a maximum. The triangle with maximum area has a height of_____cm and a base of cm_____.
Answers
The dimensions of the triangle with maximum area are a base of 11 cm and a height of 11 cm.
We are given that the sum of the base and height of a triangle is 22 cm. Let's call the base of the triangle "b" and the height "h". Then we have the equation:
b + h = 22
We want to find the dimensions of the triangle that will give us the maximum area.
The formula for the area of a triangle is A = (1/2)bh.
We can use the equation b + h = 22 to solve for one of the variables in terms of the other.
we can solve for h:
h = 22 - b
Substituting this into the formula for the area, we get:
A = (1/2)b(22 - b)
The equation 0 = 11b - (1/2)b² can be rearranged to:
(1/2)b² - 11b = 0
We can then use the quadratic formula to solve for "b"
b = 11 ± 11
So the value of b that gives us the maximum area is b = 11 cm. Substituting this back into the equation h = 22 - b, we get:
h = 22 - 11 = 11 cm
Triangle has a base of 11 cm and a height of 11 cm.

1. The breakeven in units equals 31 units.
2. The dollar amount to breakeven is
What is the breakeven in units?The variable cost per unit includes the cost of the sweatshirt ($16.50) and the additional charge for shipping and plastic wrap ($0.50), so the total variable cost per unit is:
= $16.50 + $0.50
= $17.00
The contribution margin per unit is:
= 22.00 - $17.00
= $5.00
The fixed costs include the one-time charges of art ($45), screen and set-up ($60), and advertising ($50), so the total fixed costs are:
= $45 + $60 + $50
= $155
Using the breakeven formula, we can calculate the number of units required to break even:
= Fixed costs / Contribution margin per unit
= $155 / $5.00
= 31 units
What is the breakeven in dollars?To calculate the breakeven in dollars, we need to multiply the breakeven in units by the selling price per unit:
The breakeven in dollars equals to:
= Breakeven in units x Selling price per unit

the quadratic sequence: 44; 52; 64; 80; Write down the next two terms of the sequence. Determine the nth term of the quadratic sequence. Calculate the 30th term of the sequence. Prove that the quadratic sequence will always have even terms.
Answers
To find the next two terms of the sequence, we need to first find the common difference between consecutive terms:
52 - 44 = 8
64 - 52 = 12
80 - 64 = 16
We notice that the common difference is increasing by 4 for each term. Therefore, the next two terms of the sequence are:
80 + 20 = 100
100 + 24 = 124
To determine the nth term of the quadratic sequence, we can use the formula:
an = a1 + (n-1)d + bn^2
where a1 is the first term, d is the common difference, b is the coefficient of n^2, and n is the term number.
Using the first four terms of the sequence, we can form a system of equations:
44 = a1 + b
52 = a1 + d + b
64 = a1 + 2d + b
80 = a1 + 3d + b
Solving for a1 and b, we get:
a1 = 20
b = 24
Substituting these values into the formula for an, we get:
an = 20 + (n-1)4 + 24n^2
an = 24n^2 + 4n - 4
To find the 30th term of the sequence, we simply substitute n = 30 into the formula we just derived:
a30 = 24(30)^2 + 4(30) - 4
a30 = 21,596
To prove that the quadratic sequence will always have even terms, we notice that the first term is even (44 = 2 x 22), and the common difference is even (8 = 2 x 4). Therefore, every term of the sequence can be expressed as an even number plus an even multiple of n^2, which is always even. Hence, the quadratic sequence will always have even terms.

Sequence is 44;52;64;80;.....44;52;64;80;.....

For which function does g decrease by 25% every time x increases by 1?
A g(x) = 0.75
B) g(x) = 75
g(x) = 0.25
D g(x) = 25*
Answers
We pIug this function into the equation above, we get: g(x+1) = 0.
Assume that g(x) is a function that decreases by 25% for every one increase in x.
This means that if we increase x by one, the vaIue of g(x) wiII be 75% of what it was befοre.
In other words, if g(x) is the function's vaIue at x, then g(x+1) is 0.75 times g. (x).
As a resuIt, we can express g(x+1) in terms of g(x) as foIIows:
g(x+1) = 0.75 * g(x) (x)
Let's see which οption meets this requirement.
A) g(x) = 0.75: When we pIug this function into the equation above, we get:
g(x+1) = 0.75 * 0.75 = 0.5625 * g(x) (x)
This means that increasing x by one increases g(x) by 25%. As a resuIt, this optiοn does not meet the condition.
B) g(x) = 75: When we pIug this function into the equation above, we get:
g(x+1) = 0.75 * 75 = 56.25
This means that increasing x by οne decreases g(x) by more than 25%.
As a resuIt, this option does not meet the condition.
C) g(x) = 0.25: When we pIug this function into the equatiοn above, we get:
g(x+1) = 0.75 * 0.25 = 0.1875 * g(x) (x)
This means that increasing x by one decreases g(x) by more than 25%. As a resuIt, this optiοn does not meet the cοndition.
D) g(x) = 25*: When we pIug this function into the equation above, we get:

Part III: Short Answer Items (Worth 3 points) Instruction: Write the most simplified answer on the blank space provided for each of them. 11. If the price of an item is Birr 9,500 before VAT, then the total cost of the item including VAT
Answers
According to the VAT rate, the total cost of the item including VAT is Birr 10,925 assuming a VAT rate of 15%.
What is VAT rate ?
VAT (Value Added Tax) rate is a percentage that is added to the price of goods or services. VAT is usually charged on top of the base price of a product or service, and the total price is calculated as (base price) + (base price x VAT rate). The VAT rate is typically set by the government and may be subject to change over time.
To find the total cost of the item including VAT, we need to know the VAT rate.
Let's assume the VAT rate is 15%. To calculate the VAT amount, we can multiply the price before VAT by the VAT rate:
VAT amount = 0.15 x 9,500 = Birr 1,425
The total cost of the item including VAT is the sum of the price before VAT and the VAT amount:
Total cost = 9,500 + 1,425 = Birr 10,925
Therefore, the total cost of the item including VAT is Birr 10,925 assuming a VAT rate of 15%.

Answers
The area of the square base = x².
we have:l = w = x ... (2) ... And, h = V/lw = V/x² ... (3) ...
The dimension of the box that minimizes the amount of material used is x = (2V)1/3. A(x) = x² + 4V/x, A'(x) = 2x - 4V/x², x = (2V)1/3
The given volume of the box is 62500 cm³. We wish to find the dimensions of the box that minimize the amount of material used.
To obtain the formula for the surface area of the box in terms of only x, the length of one side of the square base, we use the formula for the volume of a box:V = lwh ... (1) ... where V is the volume, l is the length, w is the width, and h is the height of the box. Here, the base of the box is a square with side length x.
Hence, the area of the square base = x². Therefore, we have:l = w = x ... (2) ... And, h = V/lw = V/x² ... (3) ... We can substitute (2) and (3) in (1) to get the formula for V in terms of x as follows:V = x² V/x² A(x) = A(x) = x² + 4xhA(x) = x² + 4x(V/x²) = x² + 4V/x
Now, to find the derivative A'(x) of A(x), we differentiate A(x) with respect to x:A'(x) = 2x - 4V/x² A'(x) = 0 when x = (2V)1/3. Therefore, the dimension of the box that minimizes the amount of material used is x = (2V)1/3. A(x) = x² + 4V/x, A'(x) = 2x - 4V/x², x = (2V)1/3

Should we write reciprocal for 5/6 in this question 5 × 5/6
Answers
If the question is simply asking for the product of 5 and 5/6, then writing the reciprocal is not necessary. To multiply fractions, we can simply multiply the numerators and the denominators separately. In this case, we would get:
5 x 5/6 = (5 x 5)/(1 x 6) = 25/6
However, if the question specifically asks for the result to be expressed as a mixed number or a whole number, then we would need to simplify the fraction by converting it to a mixed number or a whole number. In some cases, it may be helpful to write the reciprocal in order to simplify the fraction more easily.
For example, if the question asks us to express 5 x 5/6 as a mixed number or a whole number, we could first write the reciprocal of 5/6 as 6/5, and then multiply it with 5 to get:
5 x 5/6 = 5 x 6/5 = 30/5
We can simplify this fraction by dividing both the numerator and the denominator by 5:
30/5 = 6
Therefore, if the context or the desired result requires the expression 5 x 5/6 to be simplified further, it may be helpful to write the reciprocal of 5/6 to make the simplification process easier. However, in general, it is not necessary to write the reciprocal to multiply fractions.

Problem: Power Output. In each case, find your average power in watts. Assume that riding a bike burns 100 Calories per mile. If you ride at a speed of 20 miles per hour, what is your average power output, in watts?
Answers
The average power output of a bike rider at a speed of 20 miles per hour is 556 W
Given, Riding a bike burns 100 Calories per mile. Speed of riding a bike is 20 miles per hour. Power is a measure of the rate at which work is done over time.
Therefore, the formula for average power is given by,
P = W/t
Where, P is power, W is work and t is time.
Now, We know that riding a bike burns 100 Calories per mile, but we have to find out the work done.
So, work done = 100 Calories × distance traveled= 100 × 1.609 × 1000 = 160900 J
Time taken = distance/speed= 1.609/20 = 0.08045 hours
Putting values in the formula of power, we get,
P = W/t= 160900/0.08045= 1999999.9 J/hour
Converting hour to seconds,1 hour = 3600 seconds1 J/s = 1 watt1 J/hour = 1 / 3600 watt
Therefore, power = 1999999.9 / 3600= 555.5556 watts (approx)

Answers
The shipping company will need 2,688 one cubic centimeter blocks to fill the box.
The volume of the box can be calculated as:
Volume = length x width x height
Volume = 14 cm x 12 cm x 16 cm
Volume = 2,688 cubic cm
Since each block is also one cubic cm in volume, we can simply divide the total volume of the box by the volume of one block to find the number of blocks needed to fill the box:
Number of blocks = Volume of box / Volume of one block
Number of blocks = 2,688 cubic cm / 1 cubic cm

Answers
The given expression ((y-b)²/(y-b+1)+(y-b)/(y-b+1) after being reduced to a polynomial, can be represented as y-b.
In order to reduce the given equation to a polynomial, we are required to simplify and combine like terms. First, we can simplify the expression in the numerator by expanding the square:
((y-b)²/(y-b+1) = (y-b)(y-b)/(y-b+1) = (y-b)²/(y-b+1)
Now, we can combine the two terms in the equation by finding a common denominator:
(y-b)²/(y-b+1) + (y-b)/(y-b+1) = [(y-b)² + (y-b)]/(y-b+1)
Next, we can combine the terms in the numerator by factoring out (y-b):
[(y-b)² + (y-b)]/(y-b+1) = (y-b)(y-b+1)/(y-b+1)
Finally, we can cancel out the common factor of (y-b+1) in the numerator and denominator to get the polynomial:
(y-b)(y-b+1)/(y-b+1) = y-b
Therefore, the equation ((y-b)²)/(y-b+1)+(y-b)/(y-b+1) after being simplified, is equivalent to the polynomial y-b.

How do I solve this?
Answers
Answer:
X+4
Step-by-step explanation:
Area = l *b
x^2 + 13x + 36 = (X+9) * b
x^2 + 9x + 4x + 36 = (X+9) * b
X(X+9) + 4(X+9) = (X+9) * b
(X+4) (X+9) = (X+9) * b
b = (X+4)

Answer: 23
Step-by-step explanation:
Vertical angles are congruent (equal) so you first make the equations for angle A and B equal to each other and solve for x.
x + 15 = 5x - 17
32 = 4x
x = 8
Plug the x value (8) back into either equation to find the measure of angle B.
x + 15
8 + 15 = 23
Tiago sells sunflower oil in large tins and extra-large tins.
The large tin and the extra-large tin are mathematically similar.
The volume of the extra-large tin is 75% more than the volume of the large tin. Both tins are cylinders.
The radius of the large tin is 20 cm.
Calculate the radius of the extra-large tin.
Answers
Answer:
24 cm (to nearest cm)
Step-by-step explanation:
XLV = extra large tin volume (cm³)
LV = large tin volume (cm³)
XLR = extre large tin radius (cm)
LR = large tin radius (cm) = 20
XLV = 1.75 × LV
Since the tins are geometrically similar cylinders, we can infer that the volumes and radii of the 2 tins are related;
We know the relationship between the volume of the two tins, i.e. the XL tin is 75% greater in volume than the L tin;
This means the volumetric scale factor or multiplier is ×1.75;
Subsequently, we know:
XLV = 1.75 × LV
Similarly, there is a relationship between the radii of the tins;
The relationship is, however, slightly different;
[tex]XLR = (\sqrt[3]{1.75}) \times LR[/tex]
We need to take the cube root of the volumetric scale factor, reason being, the radius is a linear dimension unlike volume;
Easy way to figure this is radius is in cm, volume is in cm³;
So:
XLR = 1.205... × LR
XLR = 1.205... × 20
XLR = 24.101... --> 24 cm (to nearest cm)
