Answer:
a + b = 16 or -16.
Step-by-step explanation:
a - b = 4
ab = 60 so a = 60/b
Substituting for a in the first equation:
60/b - b = 4
60 - b^2 = 4b
b^2 + 4b - 60 = 0
(b + 10)b - 6) = 0
b = 6, -10.
Therefore, from the first equation:
When b = -10 . a + 10 =4 giving a = -6 or
When b = 6, a - 6 = 4 giving a = 10.
So when a = -6, b = -10 and
when a = 10, b = 6.
So a + b is either 16 or -16.
Hurry. A catapult launches a pumpkin with an upward velocity of 150 ft./s.
The height of the pumpkin, h, in feet after t seconds is given by the
function h = -16t2 + 150t + 20. How long does it take the
pumpkin to reach its maximum height? What is the pumpkin's
maximum height? Round to the nearest hundredth, if necessary.
Answer:
Time taken to reach maximum height=4.69 seconds
Maximum Height=371.56feet
Step-by-step explanation:
Given the height function of the pumpkin:
[Tex]h = -16t^2 + 150t + 20[/tex]
The pumpkin reaches it's maximum height at its axis of symmetry.
Therefore, we determine its equation of symmetry.
The equation of symmetry:
[Tex]t=-\frac{b}{2a}[/tex]
a=-16, b=150.
Therefore:
[Tex]t=-\frac{150}{2*-16}=4.6875[/tex]
The pumpkin reaches maximum height after 4.6875 seconds.
At t=4.6875
[Tex]h = -16(4.6875)^2 + 150(4.6875)+ 20\\=371.5625\approx 371.56 \:feet[/tex]
The pumpkin's maximum height is 371.56 feet.
What is the mode of the following set of numbers? 15, 20, 18, 20, 15, 20 A 20 B 18 C 5 D 19 .
Answer:
A
Step-by-step explanation:
Mode is the one that appears the most. The number that is there the most is 20 that makes it the mode.
The correct answer is A. 20.
To find the mode of a set of numbers, one must identify the number that appears most frequently in the list. In the given set of numbers: 15, 20, 18, 20, 15, 20, we can see that the number 20 appears three times, which is more frequent than any other number in the set. The number 15 appears twice, while the numbers 18 and 20 each appear once. Since 20 is the number with the highest frequency, it is the mode of the set.
Therefore, the mode of the given set of numbers is 20.

Does it seem fair to you that a hit could be a home run at one stadium but not at others?Explain.
Answer:
No. If standards differ at different sports stadiums, that makes the game unfair for one team or the other. A win at one stadium could be a loss at another. To make the game fair, all facilities should be equal.
Step-by-step explanation:
The unique dimensions and characteristics of each baseball stadium, known as park factors, can impact whether a hit becomes a home run. Although it might seem unfair, it's the same for all teams and is part of the game's complexity. Not only the player's skill but also their knowledge of the park's attributes can influence the outcome of the game.
Explanation:The different sizes and features of baseball stadiums, known as park factors, can impact game dynamics, including whether a hit results in a home run. This is part of the sport's complexity and challenge, as players must adapt their strategies for different venues. It might seem unfair, but it's the same for all teams as they each host and visit various stadiums throughout the season.
In some parks, for example, the distance from home plate to the outfield wall is less, which could make it easier for a hit to become a home run. In contrast, larger parks or those at higher altitudes, where the air is thinner and ball travels further, might be tougher to score a home run.
All these make baseball a fascinating sport, where not only the player's skill but also nuanced aspects like knowledge of the park play an essential role in the outcome of the game. Thus, by definition, a home run is still a successful hit, but where that hit ends up can depend on numerous variables, including the park's attributes.

Amelia runs a catering business. Based on her records, her
weekly profit can be approximated by P = 2x2 - 44x – 150,
where x is the number of meals she caters and P is her profit.
When P is negative, Amelia has lost money.
1) What is the least number of meals Amelia needs to cater
in order to begin making a profit?
2) If she caters no meals one week, how much money does
she lose?
3) What is her profit for catering 50 meals?
Answer: (1) The least number of meals is 26 (2) She loses 150 if she caters no meal in one week. (3) Her profit would be 2,650 if she caters for 50 meals in one week
Step-by-step explanation: The weekly profit is given as a quadratic equation which is;
P = 2x² -44x - 150
We begin by solving for the value of x.
When 2x² -44x - 150 = 0
Divide all through by 2
x² - 22x - 150 = 0
By factorization,
(x - 25) (x + 3) = 0
(x -25) = 0 OR (x + 3) = 0
When x - 25 = 0
x = 25
When x + 3 = 0
x = -3
What this implies is that when Amelia caters for 25 meals in a week, her profit is calculated as follows
P = 2x² - 44x -150
P = 2(25)² - 44(25) - 150
P = 2(625) - 1100 - 150
P = 1250 - 1100 - 150
P = 0
(1) Therefore she must cater for at least 26 meals before she can begin to make any profit.
(2) She loses 150 if she caters no meal in one week.
This can be calculated as follows;
When x = 0,
P = 2x² - 44x - 150
P = 2(0)² - 44(0) - 150
P = 0 - 0 -150
P = -150
(3) When she caters 50 meals her profit becomes 2,650
P = 2x² - 44x - 150
P = 2(50)² - 44(50) - 150
P = 2(2500) - 2200 - 150
P = 5000 - 2200 - 150
P = 2650
1) The least number of meals Amelia needs to cater in order to begin making a profit is 25.
2) Amelia loses $150 if she caters no meals in a week.
3) For catering 50 meals, Amelia's profit is $2650.
Explanation:1) To find the least number of meals Amelia needs to cater in order to begin making a profit, we need to determine when her profit, P, becomes positive. In other words, we need to solve the quadratic equation 2x^2 - 44x - 150 = 0 for x. This equation can be factored as (2x + 6)(x - 25) = 0. Therefore, x = -3 or x = 25. Since the number of meals cannot be negative, the least number of meals Amelia needs to cater in order to begin making a profit is 25.
2) If Amelia caters no meals one week, the profit, P, is given by P = 2(0)^2 - 44(0) - 150. Simplifying this equation, we get P = -150. Therefore, Amelia loses $150 if she caters no meals in a week.
3) To find Amelia's profit for catering 50 meals, we substitute x = 50 into the profit equation P = 2x^2 - 44x - 150. Plugging in x = 50, we get P = 2(50)^2 - 44(50) - 150 = 5000 - 2200 - 150 = $2650.

The coned shaped room has a height of 15 ft and a radius of 72. Find the volume
Answer:
81430.08
Step-by-step explanation:
Final answer:
The volume of a cone with a height of 15 ft and a radius of 72 ft is found using the formula V = (1/3)πr²h, and the calculated volume is approximately 81457.9 cubic feet.
Explanation:
The question is asking to find the volume of a cone, which has a height of 15 ft and a radius of 72 ft. The formula to calculate the volume of a cone is V = (1/3)πr²h, where 'V' represents the volume, 'r' is the radius of the base, and 'h' is the height of the cone.
To solve for the volume:
V = (1/3)π(72 ft)²(15 ft)
V = (1/3)π(5184 ft²)(15 ft)
V = (1/3)π(77760 ft³)
V = 25920π ft³
Therefore, the volume of the cone is approximately 25920π cubic feet, or when π is approximated as 3.14159, the volume is about 81457.9 cubic feet.
