SATELLITE DISH Suppose the receiver in a parabolic dish antenna is 2 feet
from the vertex and is located at the focus. Assume that the vertex is at the
origin and that the dish is pointed upward. Find an equation that models a
cross section of the dish.
a. x2 = -8y
b. x2 = 2y
c. x2 = 8y
d. y2 = 8x
Answer:
D) [tex]x^{2} =8y[/tex]
Step-by-step explanation:
Because the receiver of the parabolic dish antenna is 2 feet above the vertex, the parabola must be vertical. Therefore, we will use the equation [tex](x-h)^2=4p(y-k)[/tex] where [tex](h,k)[/tex] is the vertex of the parabola and [tex](h,k+p)[/tex] is the focus point. Since we are given that the receiver is 2 feet above the vertex which is located at the focus point and the vertex is [tex](0,0)[/tex] at the origin, then the focus point is [tex](0,0+p)[/tex] where [tex]p=2[/tex]. Therefore, the equation that models a cross section of the dish is [tex]x^{2} = 8y[/tex].

An animal shelter has three kinds of Labrador Retrievers: yellow, brown, and black. They have
both male and fomae in all of the colors. What is the probability of picking a female yellow Labrador
Retriever?
Step-by-step explanation:
There are choices when it comes to color (3). Then there is the choice between a boy dog or a girl dog (2). Multiply the number of colors by the number of genders. (6)
When choosing a dog from random, you can either choose:
Brown/M
Brown/F
Black/M
Black/F
Yellow/M
Yellow/F
(This list is called the Sample Space, a list of all possible outcomes)
Because the text says that all types of dogs are found in even numbers, it would not matter if there was 6, 12, 18, ... amount of dogs.
When looking at this sample space, you can see that the chance of choosing a Yellow/F dog, is 1 in 6.

Además, en esta situación de pandemia compran cada mes un Kit de Bioseguridad compuesto por: 4 mascarillas de tela, a S/10 cada una; 4 litros de alcohol, a S/8 cada uno, y 3 litros de lejía, a S/5 cada uno. ¿Cuál será el presupuesto mensual de la familia si además recibe S/10 por venta de una docena de huevos? ¿A cuánto asciende el gasto mensual por persona?
Answer:
a) 201s / 1000
b) 7s / 125 + s / 10 + 7s / 5 + s / 30 + s / 2
Step-by-step explanation:
Total de miembros de la familia = 4
Ganancia de la madre = s / 1000 por mes
Ganancia del papa = s / 40 por semana
Ganancia por venta de huevos = s / 10
Ganancia total por mes = s / 1000 + s / 40 * 4 + s / 10 = s / 1000 + s / 10 + s / 10 = 201s / 1000
Gasto-
Servicio - S / 250 * 4 = 4s / 250
ropa - 4S / 40
servicios de agua - 4S / 30
Electricidad - 4S / 100
paquete de teléfono, internet y cable - S / 120
gas - S / 40
alimento para pollos - S / 15 cada mes
higiene personal 4S / 20
4 mascarillas de tela - 4S / 10
4 litros de alcohol - 4 S / 8
3 litros de lejía - 3S / 5
Gastos totales = 2s / 125 + s / 10 + 2s / 15 + s / 25 + s / 120 + s / 40 + s / 15 + s / 5 + 2s / 5 + s / 2 + 3S / 5
Gasto total = 7s / 125 + s / 10 + 7s / 5 + s / 30 + s / 2

Part B: The area of a rectangle is (25x2 − 16y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
The length of each side of the square is (3x-2) units
The dimensions of the rectangle are (5x + 4y) and (5x -4y) units
Factoring an expressionFrom the question, we are to factor out the given expression for the area of the square
The expression is
9x² − 12x + 4
Factoring
9x² − 12x + 4
9x² −6x -6x + 4
3x(3x -2) -2(3x-2)
(3x -2)(3x -2)
Hence, the length of each side of the square is (3x-2) units
Part B:
The given expression is
25x² − 16y²
Factoring
25x² − 16y²
By difference of two squares, we get
(5x + 4y)(5x -4y)
Hence, the dimensions of the rectangle are (5x + 4y) and (5x -4y) units

what statement best describes the function below f(x)=x3-x2-9x+9
Answer:
It is a many-to-one function.
Step-by-step explanation:
find the other x-intercept for the parabola defined by this equation y=2x2+3-2
Answer:
( [tex]\frac{1}{2}[/tex], 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
2x² + 3x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )
Given the right triangle below, if AB = 4 and BC = 4, find AC.
By using Pythagorean's theorem we will find that the measure of AC = 5.66 units.
How to find the missing side of the right triangle?Remember that for any right triangle with an hypotenuse H and two legs A and B, the Pythagorean theorem says that:
A^2 + B^2 = H^2
Here we know that:
AB = 4
BC = 4
Because these two have the same length, we know that these two must be the legs, then AC (the side we want to find) is the hypotenuse.
Then we can write:
4^2 + 4^2 = AC^2
16 + 16 = AC^2
√(16 + 16) = AC
√32 = AC
5.65 = AC
The measure of the hypotenuse of the right triangle is 5.66 units.

PLS HELP ME FIND WHAT A AND B EQUAL
Answer:
A = 68
B = 44
Step-by-step explanation:
The sum of the angles of a triangle add to 180
A+B+C =180
x + x-24 +68 = 180
Combine like terms
2x+44 =180
Subtract 44 from each side
2x+44-44= 180-44
2x = 136
Divide by 2
2x/2 = 136/2
x = 68
A = x = 68
B = x-24 =44

Answer:
A = 20.25 sq units
Step-by-step explanation:
to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it
it appears the segment is 4.5 units so you would square that to get the area
A = 4.5²
A = 20.25
