Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9 , we have
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12
The value of the function f(5.9) will be 12. The correct option is D.
What is a function?In mathematics, a function is a rule that assigns a unique output value to each input value in a specified domain. A function is often denoted by a letter such as f, and we write f(x) to represent the output value associated with an input value x.
We know that the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example: For x= 1.5

y = ⌊3.64⌋=4

As a business goal, a small electronics store looks to sell at least $7600 worth of televisions and projection systems per day. The price per television is $475 and the price per projection system is $360. In order to keep costs down, the owner never has more than 25 items total in the store.
The question is incomplete:
As a business goal, a small electronics store looks to sell at least $7600 worth of televisions and projection systems per day. The price per television is $475 and the price per projection system is $360. In order to keep costs down, the owner never has more than 25 items total in the store. Let x represent the number of televisions and y represent the number of projection systems sold in a given day. Write a system of inequalities that describes what is necessary to obtain the stores goal.
Answer:
The system of inequalities that describes what is necessary to obtain the stores goal is:
x+y≤25
475x+360y≥7600
Step-by-step explanation:
According to the information provided, you know that the owner never has more than 25 items total in the store which means that the sum of the amount of televisions and projection systems is less than or equal to 25, which can be expressed as:
x+y≤25, where:
x is the number of televisions
y is the number of projection systems
Also, the statement indicates that the price per television is $475 and the price per projection system is $360 and that the store looks to sell at least $7600 worth of televisions and projection systems per day. This means that the result of adding up the sales of televisions and projection systems should be greater than or equal to 7600:
475x+360y≥7600
The answer is that the system of inequalities that describes what is necessary to obtain the stores goal is:
x+y≤25
475x+360y≥7600

What is an equation of the line that passes through the points (-6, 2) and (6, –2)?
Answer:
y=(-1/3)x
Step-by-step explanation:
y=mx+b
(x,y)
put in the first point into y=mx+b
2=m(-6)+b
then the second point is (6,-2)
put the point into y=mx+b
-2=6m+b
----------------------------
Put both equations in a system of equations
-2=6m+b
2=m(-6)+b
solve for m and b
-1/3=m and 0=b
so put that back into y=mx+b
y=(-1/3)x+0
so that is the only line that passes through both points
Consider a quadratic equation with integer coefficients and two distinct zeros. If one zero is irrational, what is true about the other zero
Answer:
Step-by-step explanation:
irrational roots always occur in pairs.
Other root is also irrational and is negative of first zero.
If a quadratic equation with integer coefficients and two distinct roots have one irrational root then another root is also irrational .
What is quadratic equation ?Any equation of the form [tex]ax^{2}+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .
Let assume quadratic equation is
[tex]ax^{2}+bx+c=0[/tex]
Given that coefficients are integer and roots are distinct
we know root of quadratic equation are
[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]
As roots are distinct
[tex]b^2-4ac > 0\\[/tex]
and one root is irrational so [tex]b^2-4ac[/tex] is not a perfect square
Hence another root is also irrational .
If a quadratic equation with integer coefficients and two distinct roots have one irrational root then another root is also irrational .

Caleb a organizado en si horario personal 6,5 horas de tiempo libre al día. Como desea ser un futbolista profesional, usa 6/13 de su tiempo libre para hacer ejercicios distintos para fortalecer su cuerpo, y el resto del tiempo libre juega fulbito con sus amigos de la comunidad. ¿Cuantas horas a la semana dedica Caleb para fortalecer su cuerpo y jugar fulbito?
Responder:
Fortalecimiento = 21 horas
Jugar al fútbol = 24,5 horas
Explicación paso a paso:
Número de horas diarias = 6. 5 horas
Fracción de fortalecimiento del tiempo: 6/13
Por lo tanto, el tiempo dedicado al fortalecimiento diario = 6/13 * 6.5 horas = 6/13 * 6.5 horas = 3 horas
Tiempo total dedicado a la semana =. 3 * 7 = 21 horas
Tiempo diario dedicado a jugar al fútbol = (6,5 - 3) = 3,5 horas
Tiempo total invertido por semana:
3,5 * 7 = 24,5 horas

Carlos has 2.6 meters of wire. He has 3 projects for which he needs 0.9 meters each. Does carlos have enough wires?
Answer: Carlos does not have enough wires by 0.1 meters
Step-by-step explanation:
To determine if Carlos has enough wires, you need to find out the total amount of wires needed and then compare this to the amount of wires that Carlos has already.
= 0.9 + 0.9 + 0.9
= 2.7 meters
Carlos has 2.6 meters of wire but needs 2.7 meters.
Carlos therefore, does not have enough wires.

Leo has a lock box with a volume of 312 cubic inches. The box is 4 inches high and 13 inches long. What is the width of the box?
Answer:
6in
Step-by-step explanation:
Given data
Volume of the lockbox= 312 cubic inches
Height= 4in
Length= 13in
Width= ???
The expression for the volume of box is
V= L*W*H
substitute
312=13*W*4
312=52W
W= 312/52
W=6 in
Hence the width is 6in
