Rectangle ABCD is dilated by a scale factor of 2 with the origin as the center of dilation, resulting in the image A'BCD. If the slope of AB Is-2,
what is the slope of A' B'?
Answer:
C. -2
Step-by-step explanation:
A (x,y) B(x',y') slope of AB = (y'-y)/(x'-x) = -2
After dilation with factor of 2:
A' (2x,2y) B' (2x',2y') slope of A'B' = (2y'-2y)/(2x'-2x) = (y'-y)/(x'-x) = -2
The slope of A' B' is the same as the slope of AB, which is -2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The slope of line AB is -2, and the slope of A' B' can be found by applying the transformation to the slope of AB.
Since the dilation is centered at the origin and has a scale factor of 2, the slope of line A' B' is also -2.
This is because the transformation multiplies the distances between points by 2 in every direction, but it does not change the angle between the lines.
Therefore, the slope of A' B' is the same as the slope of AB, which is -2.

Luis posee un terreno y va a colocar un cerco de forma rectangular con una malla 80 metros de longitud. Para ello ha establecido dos objetivos:
•Utilizar toda la malla (los 80 metros).
•La superficie que desea cercar debe ser la máxima posible.
Si "x" e "y" representan las dimensiones del terreno.
a) ¿Cuál es la función qué relaciona las dimensiones del terreno?
b) ¿Cuál seria la función qué relaciona el área del terreno con dimensiones?
c) Representa en el plano cartesiano la función relaciona el área del terreno con una de sus dimensiones
d) ¿Cuánto debe medir el ancho y el largo del terreno para que el área sea la máxima posible? Justifica tu respuesta
Queremos resolver distintas cosas en relación a las dimensiones de un rectangulo, las respuestas son:
a) 80m = 2*(x + y)
b) A = (40m - y)*y = 40m*y - y^2
c) El grafico se puede ver al final de la respuesta.
d) Tanto el largo como el ancho deben ser iguales a 20m
Luis quiere colocar un cerco rectangular, definamos, x como el largo e y como el ancho de este rectangulo.
Recordar que el area está dada por:
A = x*y
y el perimetro está dado por:
P = 2*(x + y)
Ahora sabemos que el desea utilizar una malla de 80 metros de longitud, es decir, el perimetro debe ser:
P = 80m = 2*(x + y)
Ahora tenemos una ecuación que relaciona las dimensions del terreno.
a) 80m = 2*(x + y)
b) La ecuación del area es:
A = x*y
Usando la ecuación del inciso (a) podemos escribir:
80m = 2*(x + y)
40m = x + y
x = 40m - y
Ahora podemos reemplazar esto en la ecuación del area:
A = (40m - y)*y = 40m*y - y^2
c) El grafico se puede ver al final de la respuesta.
d) Queremos maximizar el area.
Notar que la ecuación del area es cuadratica, es decir, el máximo esta en el vertice, y el vertice está dado por:
y = -40m/(2*-1) = 20m
Usando la ecuación x = 40m - y podemos encontrar el valor de x:
x = 40m - y = 40m - 20m = 20m
Es decir, el largo y el ancho deben ser iguales a 20 metros.

Evaluate the equation −12/c=6
Answer:
-2
Step-by-step explanation:
First you want to seperate the c. To do that you divide by both sides so -12/c divide -12 cancels out to be just 1/C. 6 divide -12 is -0.5. Know we have 1/c = -0.5 and that is -2. -2 is your answer :)

A payday loan store charges $45 for a one-month loan of $720. What annual interest rate is this equivalent to?
Answer:
$720 multiplication
$45=n 32‚400
The annual interest rate for the one-month loan is approximately 9.375%.
To calculate the annual interest rate equivalent to the one-month loan, we need to determine the interest paid over the course of a year.
The total amount paid for the one-month loan is the sum of the principal and the charge, which is $720 + $45 = $765.
The interest paid on the loan is the difference between the total amount paid and the principal, which is $765 - $720 = $45.
To find the annual interest rate, we need to calculate the interest as a percentage of the principal and then multiply it by the number of times the loan is made in a year (since it is a one-month loan).
The loan is made for one month, so the number of times the loan is made in a year is 12 (12 months).
The annual interest rate is (45 / 720) * 12 * 100 ≈ 9.375%.
Therefore, the annual interest rate for this payday loan is approximately 9.375%.

Multiply and simplify the product. (3 – 5i)(–2 + 4i) Select the product. 14+ 2i 14 + 22i 15 + 22i 26 + 2i
Answer:
I got -6 + 2i
Step-by-step explanation:
(3-5i)(-2+4i)
So we would multiply the following:
3*-2 = -6
3*4i =12i
-5i*-2 = 10i
-5i * 4i = -20i
Therefore the expression would be
- 6 + 12i + 10i - 20i
we then would add and subtract the variables, which would be
-6 + 2i
