Answer:
Some key features quadratic functions have are:
Axis of symmetryx and y-interceptsZeroesvertexPoint symmetric to y-interceptStep-by-step explanation:
Answer: You could say something like this ''I think the opposite function of a quadratic function would have an inverted parabolic curve that always opens upwards, since a quadratic function can open upwards or downwards. It would also have a single maximum or minimum point, depending on the coefficient of the quadratic term, since a quadratic function has a single vertex. Finally, the opposite function would have either no real roots or two real roots with opposite signs, depending on the discriminant, since a quadratic function can have either two distinct real roots or two complex roots.''

are late for their plane each day. However, during the
Christmas holidays, there are 1,835 passengers that are late for
their planes each day which caused delays of 14 planes. How
many more passengers are late for their planes in each day
during the Christmas holidays?
An average of 782 travelers miss their flight each day during a typical day. In contrast, 1,835 passengers are late for their flights every day over the Christmas holiday, which results in 14 planes being delayed.
1,053 travelers (2,835-782 = 1,053)
During the Christmas holidays, there are 1,053 extra passengers who are late for their flights.
How do you figure out the average number of days late?In order to compute WADO, we multiply the total amount of each overdue invoice by the number of days past due, then divide that total by the number of days past due. You may figure out your average daily sales by dividing your total sales over a certain period of time by the number of days in that same period.

A. Encuentra el valor del tercer ángulo en un triángulo que tiene dos ángulos que miden 112º Y 52º B. Encuentra el valor del cuarto ángulo en un cuadrilátero que tiene los siguientes ángulos: 105º, 32º Y 10º
Answer:
El tercer ángulo en un triángulo será 16 ° si los otros dos ángulos son 112º y 52º.
El cuarto ángulo en un cuadrilátero será 213 ° si los otros tres ángulos son 105º, 32º y 10º.
Step-by-step explanation:
Spanish
La suma de los ángulos de un triángulo siempre es igual a 180 grados. Si conocemos dos de ellos, podemos encontrar el tercero. Dejemos que el tercero se denote por x entonces
112 ° + 52 ° + x = 180 °
x = 180 ° -112 ° -52 °
x = 16 °
El tercer ángulo en un triángulo será 16 ° si los otros dos ángulos son 112º y 52º.
La suma de los ángulos de un cuadrilátero siempre es igual a 360 grados. Si conocemos tres de ellos, podemos encontrar el cuarto. Dejemos que el cuarto se denote por y luego
105º + 32º + 10º + y = 360 °
o
y = 360 ° -105º- 32º- 10º
y = 213 °
El cuarto ángulo en un cuadrilátero será 213 ° si los otros tres ángulos son 105º, 32º y 10º.
English
The sum of angles in a triangle is always equal to 180 degrees. If we know any two of them we can find the third one. Let the third one be denoted by x then
112°+52°+x= 180°
x= 180°-112°-52°
x= 16°
The third angle in a triangle will be 16° if the other two angles are 112º and 52º.
The sum of angles in a quadrilateral is always equal to 360 degrees. If we know any three of them we can find the fourth one. Let the fourth one be denoted by y then
105º+ 32º+ 10º+y= 360°
or
y = 360°-105º- 32º- 10º
y= 213°
The fourth angle in a quadrilateral will be 213° if the other three angles are 105º, 32º and 10º.

Paige has set a goal to earn at least $220 from her part time sales job this month. she earns $20 regardless of what she sells for the month and then 20% Commission on all product sales. Write inequalities that can be used to determine X the amount of product sales Paige needs to make her goal for the month.
Answer:
The required inequality is;
0.2·X + 20 > 220
Step-by-step explanation:
The parts of the required inequality are;
The goal amount Paige set to earn for the month = At least $220
The amount she earns regardless of what she sells = $20
The percentage commission she gets for all product sales = 20%
Given that 'X' represent the amount of product sales Paige makes, we have;
The amount Paige makes in a month, A = 20% × X + 20 = 0.2·X + 20
Therefore, given that Paige's goal is to earn at least $220 from her part time sales in the current month, we get the inequality that can be used to determine the value of 'X' Paige needs to make are goal as follows;
A = 0.2·X + 20 > 220
The required inequality = 0.2·X + 20 > 220
∴ X > (220 - 20)/0.2 = 1,000
From which we get;
The amount of product sales Paige needs to make her goal, X > 1,000.

Answer:
Los resultados están abajo.
Step-by-step explanation:
Dada la siguiente información:
Inversión inicial (VP)= $20.000
Tsa de interés (i)= 0,09/2= 0,045
Para calcular la cantidad de semestres necesarios (n) para lograr el valor requerido, debemos usar la siguiente formula:
n= ln(VF/VP) / ln(1+i)
25.000:
n= ln(25.000/20.000) / ln(1,045)
n= 5,07 semestres
30.000:
n= ln(30000/20.000) / ln(1,045)
n= 9,21 semestres
40.000:
n= ln(40.000/20.000) / ln(1,045)
n= 15,75 semestres

Using Pythagoras theorem to solve the right angle triangle, the height of the building is 14.87 feet
What is Pythagoras TheoremPythagoras Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. This can be expressed as an equation:
x² = y² + z²
where x is the hypothenuse and y, z are the legs of the right angle triangle.
To determine the height of the building in which the ladder will reach, we have to use Pythagoras theorem for that.
x² = y² + z²
15² = 2² + z²
z² = 15² - 2²
z² = 221
z = √221
z = 14.87 feet
