A radio station signal covers a circular area out from the signal tower. It gets weaker the farther away your are. The local station WDHS (at location (0,0)) sends it signal out with a coverage radius of 5 miles. 1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning. 2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
Answer:
1. We would hear better at Dunkin's since its distance from the radio station is the shortest.
2. McDonald's is out of range of the radio station since its distance is greater than the range of the radio station.
Step-by-step explanation:
1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning.
We need to find the distance of each point from the tower.
The shorter the distance from the radio station the better the signal.
The distance between two points (x₁, y₁) and (x₂, y₂) is given by d = √[(x₂ - x₁)² + (y₂ - y₁)²].
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
Since Dunkin's distance, d₃ = 4.24 is the least distance from the radio station and is within range of 5 miles, we would hear better at Dunkin's.
2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
The radio station is outside of range if its distance is greater than 5 miles. That is, d > 5 miles.
So, we calculate the distance of each point from the radio station.
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
So, for each of the distances calculated above, only McDonald's distance, d₂ = 5.66 miles > 5 miles.
So, McDonald's is out of range of the radio station.

¿Cuál de los siguientes números racionales es equivalente a un decimal finito? * a 1/3 b 1/5 c 2/6 d 2/3 e 5/6 ayudaa
Answer:
De los números racionales dados, aquel que es equivalente a un decimal finito es:
b. 1/5Step-by-step explanation:
Los decimales finitos, son aquellos cuyos números después del punto decimal no se extienden hasta el infinito sino que pueden ser contados fácilmente, por ende, lo que debes hacer en cada caso es dividir el número decimal e identificar si sus cifras decimales son infinitas o no, a continuación te mostraré la división en cada uno de los casos y podrás comprobar la respuesta correcta, (en caso de que los decimales sean infinitos utilizaré puntos suspensivos al final del número):
1/3 = 0.3333333333333...1/5 = 0.22/6 = 0.333333333333...2/3 = 0.666666666666...5/6 = 0.833333333333...Como puedes notar, la única opción que equivale a un decimal finito, en este caso 0.2, es 1/5.

Twice a number added to another number is -8. The difference of the two numbers is 2. Find the
numbers.
Answer:
-2, -4
and
-1 1/3, -3 1/3
Step-by-step explanation:
2×x + y = -8
x - y = 2 or y - x = 2
first going for x-y=2
so, x = 2 + y
=> 2×(2+y) + y = -8
4 + 2y + y = -8
3y = -12
y = -4
=> x = 2 + -4 = -2
second going for y-x=2
-x = 2 -y
x = y - 2
=> 2×(y-2) + y = -8
2y - 4 + y = -8
3y = -4
y = -4/3 = -1 1/3
=> x = -4/3 - 2 = -3 1/3 (or -10/3)
which of the following represents h (x-2) + 3
Answer:
A
Step-by-step explanation:
For transformation functions;
(x-2), the 2 represents horizontal shift (left or right)
if it is a positive= shift left
if it is a negative= shift right
since it is -2, the vertex of the graph is shifted right by 2 units.
For the +3 on the outside of h(x-2), this addresses the vertical shift.
Since it is +3, this means that the graph's vertex is shifted up.

help please! quadratic equation and stretch factor
Answer:
Equation: f(x)=x²-4x+3
Stretch factor: a=1
Step-by-step explanation:
Notice the x-intercepts are (1,0) and (3,0) which can help us determine the equation by setting their expressions equal to 0 and expanding:
(x-1)(x-3)=0
x²-4x+3=0
Therefore, the equation is f(x)=x²-4x+3 where the stretch factor is a=1

You want to produce a scale drawing of your living room which is 14 ft by 16 ft if you use a scale of 2 in = 4 ft what will be the dimensions of your scale drawing.
Answer:
7 in by 8 in
Step-by-step explanation:
The dimensions of the living room is 14 ft by 16 ft
In the scale drawing 2 in = 4 ft
[tex]1\ \text{in}=2\ \text{ft}[/tex]
So, 1 in of the scale drawing represents 2 ft in the real world.
[tex]1\ \text{ft of the actual dimension}=\dfrac{1}{2}\ \text{in in the scale drawing}[/tex]
[tex]14\ \text{ft}=\dfrac{14}{2}=7\ \text{in of the scale drawing}[/tex]
[tex]16\ \text{ft}=\dfrac{16}{2}=8\ \text{in of the scale drawing}[/tex]
Hence, the dimensions of the scale drawing are 7 in by 8 in.

Answer:
D. (-3/8) (-5/7) (-1/4)
Step-by-step explanation:
Hints:
- * - * + = +
+ * - * - = +
+ * + * + = +
- * - * - = -
A. (-3/8)(-5/7)(1/4)
= (-3*-5*1) / (8*7*4)
= 15/224
B. (3/8)(-5/7)(-1/4)
= (3*-5*-1) / (8*7*4)
= 15/224
C. (3/8)(5/7)(1/4)
= (3*5*1) / (8*7*4)
= 15/224
D. (-3/8) (-5/7) (-1/4)
= (- 3*-5*-1) / (8*7*4)
= (-15)/(224)
= -15/224
The correct option is
D. (-3/8) (-5/7) (-1/4)
