If m is 2 times n minus 7 and y is the square of m, then write y as a function of n.
Answer:
y = 4n^2
Step-by-step explanation:
Because m = 2n, and y = m^2, then substitute m = 2n into y equation, can get y = (2n)^2 = 4n^2.

Answer:

Step-by-step explanation:
The guy below is wrong because I got a 100 on the quiz on Edge.
On a coordinate plane, a parabola opens up. It goes through (negative 3, 3), has a vertex at (negative 1.5, 0.75), and goes through (0, 3).
Which function has a y-intercept of 3?First, for a function f(x), the y-intercept is the value that takes f when we evaluate in x = 0.
Then we must have:
f(0) = 4, so, the function must pass through the point (0, 3).
From the given options, the only one that passes trough that point is the first one:
"On a coordinate plane, a parabola opens up. It goes through (negative 3, 3), has a vertex at (negative 1.5, 0.75), and goes through (0, 3)."

find the area of the figure 27 1/2 yd and 17 1/5 yd
if the figure is a rectangle the answer is 473
Answer:
473
Step-by-step explanation:
First you need to make the fractions mixed numbers
27 1/2= 55/2
17 1/5= 86/5
Then you multiply across
55/2*86/5= 4730/10
then you divide 4730 by 10 to make it an improper fraction.
(because the denominator is 10 just take the 0 out of the end of 4630, this trick only works if the last number in the numerator is 0.)
And your anwser should be 473

What is the area of the figure in
square units.
Answer:
Area = 132 Square units
Step-by-step explanation:
Looking at the diagram, the top horizontal chord distance that's missing is calculated as;
21 - (9 + 3) = 9 units
Total distance of top horizontal chord = 9 + 3 = 12 units
Now, formula for area of trapezium is;
Area = ½(a + b)h
Where h is height = 8 units
The parallel sides are a & B.
In this case; a = 12 units
b = 21 units
Thus;
Area = ½(12 + 21)8
Area = 4 × 33
Area = 132 Square units

la probabilidad de que un caballo viva 20 años es dos tercios y la de una vaca viva 20 años es decir 3 puntos Cuál es la probabilidad de que tanto el caballo como la vaca vivan 20 años
Answer:
La probabilidad de que tanto el caballo como la vaca vivan 20 años es [tex]\frac{2a}{3b}[/tex], en que [tex]\frac{a}{b}[/tex] es la probabilidad de que una vaca viva 20 años.
Step-by-step explanation:
Probabilidades Independientes:
Quanto las probabilidades de dos eventos son independientes, la probabilidad de los dos ocurrir simultáneamente es la multiplicacion de las dos probabilidades.
La probabilidad de que un caballo viva 20 años es dos tercios
Entonces [tex]P(C) = \frac{2}{3}[/tex]
La de una vaca viva 20 años es
Incomplete, entonces dire que es [tex]P(V) = \frac{a}{b}[/tex]
Cuál es la probabilidad de que tanto el caballo como la vaca vivan 20 años
[tex]P(C \cap V) = P(C) \times P(V) = \frac{2}{3}*\frac{a}{b} = \frac{2a}{3b}[/tex]
La probabilidad de que tanto el caballo como la vaca vivan 20 años es [tex]\frac{2a}{3b}[/tex], en que [tex]\frac{a}{b}[/tex] es la probabilidad de que una vaca viva 20 años.
La probabilidad de que tanto el caballo como la vaca vivan 20 años es [tex]\frac{2}{5}[/tex].
Sean [tex]A[/tex] y [tex]B[/tex] dos eventos independientes aunque no mutuamente excluyentes, es decir, que la esperanza de vida del caballo ([tex]A[/tex]) no dependa de la esperanza de vida de la vaca ([tex]B[/tex]) y viceversa y que pueden ocurrir al mismo tiempo.
En este caso, la probabilidad de que tanto el caballo como la vaca vivan 20 años equivale a una operación de intersección que se manifiesta en la siguiente ecuación:
[tex]P(A \cap B) = P(A)\cdot P(B)[/tex] (1)
Si sabemos que [tex]P(A) = \frac{2}{3}[/tex] y [tex]P(B) = \frac{3}{5}[/tex], entonces la probabilidad de que tanto caballo como la vaca vivan 20 años es:
[tex]P(A\cap B) = \frac{2}{3}\times \frac{3}{5}[/tex]
[tex]P(A\cap B) = \frac{2}{5}[/tex]
La probabilidad de que tanto el caballo como la vaca vivan 20 años es [tex]\frac{2}{5}[/tex].

Three of the sides will require fencing and the fourth wall already exists. If the farmer has 144 feet of fencing what is the largest area the farmer can enclose ?
Complete question is;
A farmer is building a fence to enclose a rectangular area against an existing wall. Three of the sides will require fencing and the fourth wall already exists. If the farmer has 144 feet of fencing, what is the largest area the farmer can enclose?
Answer:
A_largest = 2592 ft²
Step-by-step explanation:
Let the width which is going to be perpendicular to the already existing fourth wall be denoted by y. Since there will be 2, it means total width = 2y.
Since the farmer has 144 ft of fencing and the total width is 2y,it means that the length of the fence will be expressed as;
Length = 144 - 2y
Area of rectangular fencing is;
A = y(144 - 2y)
A = 144y - 2y²
To find the largest area, we will find the first derivative and the equate to 0 after which we plug the value of y back into the area equation to get it.
dA/dy = 144 - 4y
At dA/dy = 0;
144 - 4y = 0
y = 144/4
y = 36 ft
Thus, largest area is;
A_largest = 144(36) - 2(36)²
A_largest = 2592 ft²
The largest area the farmer can enclose with the fence with him will be 2592 square feet.
Let the length of the field = [tex]x[/tex] feet
And the width of the field = [tex]y[/tex] feet
Therefore, area of the rectangular field = Length × Width
A = [tex]x\times y[/tex] square feet
Since, length of the fence = 144 feet
And the farmer has to enclose three sides of the rectangle as shown in the figure attached.
Therefore, length of the fence = length + 2(width)
= [tex](x+2y)[/tex] feet
Hence, [tex](x+2y)=144[/tex]
[tex]x=144-2y[/tex]
By substituting the value of 'x' in the expression for the area of the rectangular field.
[tex]A=(144-2y)y[/tex]
[tex]A=-2y^2+144y[/tex]
Find the derivative of the expression with respect to [tex]y[/tex],
[tex]A'=-4y+144[/tex]
Now equate it to zero to get the value of y,
[tex]A'=-4y+144=0[/tex]
[tex]y=36[/tex]
Now substitute the value of 'y' in the expression of area to get the maximum area enclosed.
[tex]A=-2(36)^2+144(36)[/tex]
[tex]=-2592+5184[/tex]
[tex]=2592[/tex] square feet
Therefore, maximum area the farmer can enclose with the 144 feet of fencing will be 2592 square feet.

si f(X)=1/X2, determina el conjunto finito de pares ordenados para X={1,3,7,11,13}
Answer:
El conjunto finito de pares ordenados son;
(1, 1), (1, 1/9), (1, 1/49), (1, 1/121), (1, 1/169)
Step-by-step explanation:
si f (X) = 1 / X2, determine el conjunto finito de pares ordenados para X = {1,3,7,11,13}
Dado que f (X) = 1 / X²
Para X = {1, 3, 7, 11, 13}
Tenemos;
f (X) = 1 / X²
f (1) = 1 / 1² = 1, Por lo tanto, tenemos el primer par ordenado, (1, 1)
f (3) = 1 / 3² = 1/9, por lo tanto, tenemos el segundo par ordenado (1, 1/9) ≈ (1. 0.11)
f (7) = 1 / 7² = 1/49, por lo tanto, tenemos el tercer par ordenado (1, 1/49) ≈ (1. 0.02)
f (11) = 1 / 11² = 1/121, por lo tanto, tenemos el cuarto par ordenado (1, 1/121) ≈ (1. 0083)
f (13) = 1 / 13² = 1/169, por lo tanto, tenemos el quinto par ordenado (1, 1/169) ≈ (1. 0.006)

Now find P( For G) by counting the numb er of outcomes in For G. Determine P (For G ) using the General Addition Rule.
Answer:
[tex]F\ or\ G= \{5,6,7,8,9,10,11,12\}[/tex]
[tex]P(F\ or\ G) = \frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]S= \{7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18\}[/tex]
[tex]E=\{9, 10, 11, 12, 13, 14, 15, 16\}[/tex]

[tex]G=\{9, 10, 11, 12\}[/tex]
[tex]H=\{2, 3, 4\}.[/tex]
Solving (a): Outcomes of F or G
F or G is the list of items in F, G or F and G.
So:
[tex]F=\{5, 6, 7, 8, 9\}[/tex]
[tex]G=\{9, 10, 11, 12\}[/tex]
[tex]F\ or\ G= \{5,6,7,8,9,10,11,12\}[/tex]
Solving (b): P(F or G)
The general addition rule is:
[tex]P(F\ or\ G) = P(F) + P(G) - P(F\ and\ G)[/tex]
Where:
[tex]P(F) = \frac{n(F)}{n(S)} = \frac{5}{12}[/tex]
[tex]P(G) = \frac{n(G)}{n(S)} = \frac{4}{12}[/tex]
[tex]P(F\ and\ G) = \frac{n(F\ and\ G)}{n(S)}[/tex]
[tex]F\ and\ G = \{9\}[/tex]
So:
[tex]P(F\ and\ G) = \frac{1}{12}[/tex]
[tex]P(F\ or\ G) = P(F) + P(G) - P(F\ and\ G)[/tex]
[tex]P(F\ or\ G) = \frac{5}{12} + \frac{4}{12} - \frac{1}{12}[/tex]
[tex]P(F\ or\ G) = \frac{5+4-1}{12}[/tex]
[tex]P(F\ or\ G) = \frac{8}{12}[/tex]
[tex]P(F\ or\ G) = \frac{2}{3}[/tex]
