Answer:
y = 20 [tex]4^{x}[/tex]
Step-by-step explanation:
Use the points to find the values of a and b
Using (0, 20 ) , then
20 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
20 = a
y = 20[tex]b^{x}[/tex]
Using (3, 1280 ) , then
1280 = 20 b³ ( divide both sides by 20 )
64 = b³ ( take the cube root of both sides )
[tex]\sqrt[3]{64}[/tex] = b , that is
4 = b
Then exponential function is
y = 20. [tex]4^{x}[/tex]

Answer:
x=4 y=3
Step-by-step explanation:
y=x-1
2x-3y=-1
put x-1 in for y and solve
2x-3(x-1)=-1
2x-3x+3=-1
-x+3=-1
-x=-4
x=4
put 4 in for y and solve
y=4-1
y=3

for all positive angles less than 360°, if csc csc (2x+30°)=cos cos (3y-15°), the sum of x and y is?
Answer:
35 degrees
Step-by-step explanation:
for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?
Let the given expression be equal to 1, hence;
csc (2x+30°)= cos (3y-15°) = 1
csc (2x+30°) = 1
1/sin(2x+30) = 1
1 = sin(2x+30)
sin(2x+30) = 1
2x+30 = arcsin(1)
2x+30 = 90
2x = 90-30
2x = 60
x = 60/2
x = 30 degrees
Get the value of y;
cos (3y-15°) = 1
3y - 15 = arccos (1)
3y - 15= 0
3y = 0+15
3y = 15
y = 15/3
y = 5
Sum of x and y;
x+y = 30 + 5
x+y = 35degrees
Hence the sum of x and y is 35 degrees

Ejercicio. Supongamos que el total de estudiantes en tu escuela es 256. Se te ha pedido elegir
al azar una muestra de 15 estudiantes a los cuales se les aplicará un examen para evaluar las
condiciones físicas en las que se encuentran. Describe en tu libreta al menos dos maneras
diferentes de como podrías realizar la selección de manera que los 15 estudiantes representen
una buena muestra del total de estudiantes
Responder:
Por favor, consulte la explicación
Explicación paso a paso:
Para garantizar que la selección realizada sea representativa, la selección debe ser aleatoria.
1.) Se puede elegir una muestra totalmente aleatorizada de 15 integrantes de niños y niñas en igual proporción. Es decir, si toda la población tiene un 60% de niñas y un 40% de niños, entonces una muestra puede incluir;
0.4 * 15 = 6 niños
0,6 * 15 = 9 niñas
Además, la muestra se puede seleccionar asignando al azar 15 números a un trozo de papel enrollado donde se les puede pedir a todos los estudiantes que elijan. los estudiantes que eligen los trabajos numerados se utilizan como muestra.

A band is traveling to a new city to perform a concert. The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x). What are the two ticket prices at which the band would make no money at all?
Answer:
[tex]x=6,50[/tex]
Step-by-step explanation:
The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with [tex](x-6)(250-5x)[/tex]
To find the two ticket prices at which the band would make no money at all, solve the following equation:
[tex](x-6)(250-5x)=0\\x-6=0\,,\,250-5x=0\\x=6\,,\,5x=250\\\\x=6\,,\,x=\frac{250}{5}\\\\x=6,50[/tex]
The two ticket prices at which the band would make no money at all is 6, 50.
Calculation of the two ticket prices:Since the revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x).
So here it can be like
(x - 6) (250 - 5x) = 0
x - 6 = 0, 250 - 5x = 0
x = 6, 5x = 250
x = 5, x = 50
hence, The two ticket prices at which the band would make no money at all is 6, 50.

64+64The sum of two numbers is 25 one number is twice the second number plus seven What are the two numbers
Answer:
The two numbers are 6 and 19
Step-by-step explanation:
Assume that the two numbers are x and y
We are given that:
The sum of the two numbers is 25
This means that:
x + y = 25 ..........................> equation 1
We are also given that:
One number is twice the other plus 7
This means that:
x = 2y + 7 ..........................> equation 2
Substitute with equation 2 in equation 1 and solve for y:
2y + 7 + y = 25
3y + 7 = 25
3y = 18
y = 6
Now, substitute with the value of y in equation 2 to get x as follows:
x = 2y + 7
x = 2(6) + 7
x = 12 + 7
x = 19
Based on the above, we can conclude that the two numbers are:
6 and 19
Hope this helps :)
x+y=25 => x=-y+25
x= 2y+7
x=-y+25
x=2y+7
subtract the first equation from the 2nd
0=3y-18
y=6
x=19
