Find the zero of the function f(x)=4x^2-12x+9

Answer:

Step-by-step explanation:

Given the dimensions are

length=  5.2 × 10^5meters

width= 3 .7 × 10^6meters

We know that area is given as

Area=length * width

Area=5.2 × 10^5* 3 .7 × 10^6

Area= 5.2*3.7*10^5+6

Area=19.24*10^11meters

Therefore the area is 19.24*10^11meters

The type of relationship expressed below is an INEQUALITY

Step-by-step explanation:

To solve it (though it isn't asked for but may help in the future) you would have to combine like terms.

Add 3.0 and 2, you get 5.

5 isn't greater than 10 so this inequality would be incorrect.

Answer:

6 feet

Step-by-step explanation: If a 10 foot object casts a 12 foot shadow, that means the shadow is 1.2 times the objects height. If the person is 5ft tall 5 x 1.2 = 6 feet

Answer:

6 ft. Shadow

Step-by-step explanation:

I am not 100% sure if this is correct but hopefully it is!

If something 10ft. high casts a 12ft. shadow then something half of 10ft. or 5 ft. would cast a 6ft. shadow.

Hope this Helps!!! :)

Answer: 57

Step-by-step explanation: x = 74 - 17

Step-by-step explanation:

2(x-3)+3=6x-5

2x-6+3=6x-5

2x-3=6x-5

2x-6x= -5+3

-4x=-2

x=2/4

4(x-6)+4=6x-8

4x-24+4=6x-8

4x-20=6x-8

4x-6x= -8+20

-2x=12

x= 12/2

Answer:

m<3 = 82°, m<2 = 98°, m<4 = 98°

Step-by-step explanation:

360 - Overall Sum

m<1 = m<3 (They are symmetrical)

m<2 = m<4 (They are symmetrical)

if m<1 = 82°, then m<3 = 82° [= 164]

360 - 164 = 196

if m<2 = ?°, then m<4 = ?° [= 196]

196/2 = 98

Answer:

Step-by-step explanation:

2x-y=2 is in standard form

y=mx+b is slope-intercept form, where m is the slope and b is the y-intercept

y=2x-2 is in slope-intercept form

y-y1=m(x-x1) is point-slope form, where m is the slope and (x1,y1) is a point on the line

y-4=2(x-3) is in point-slope form

Step-by-step explanation:

[tex]X_1 = 7X_2\\X_1 + X_2 \leq 60\\7X_2 + X_2 \leq 60\\8X_2 \leq 60\\[/tex]

since the two numbers are integers,

the largest the smaller number can be is 7

so our numbers are

[tex](1, 7), (2, 14), (3, 21), (4, 28), (5, 35), (6, 42), (7, 49)[/tex]

the two integers are 7, 49

The largest two numbers which make the statement true are 7 and 49.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given that the larger of two integers is 7 times the smaller. The sum of the integers is at most 60.

The two equations will be,

x₁ = 7x₂

x₁ + x₂ ≤ 60

7x₂ + x₂≤ 60

8x₂ ≤ 60

The collection of the numbers are (1,7),(2,14),(3,21),(4,28),(5,35),(6,42),(7,49).

The largest number is 7 in the collection.

Therefore, the largest two numbers which make the statement true are 7 and 49.

Answer:

no

Step-by-step explanation:

angles must be congruent as well

Two quadrilaterals with the same side lengths not always congruent.

We need to check whether two quadrilaterals with the same side lengths

always congruent.

Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same. To do this we need to check all the angles and all the sides of the shapes. If two shapes are congruent they will fit exactly on top of one another.

Generally we have to put side's interior angles of one quadrilateral in correspondence with sides and angles of another and to prove that all correspondence with sides and angles of another and to prove that all corresponding pairs of sides and angles are congruent.

No, two quadrilaterals with the same side lengths not always congruent.

Answer:

a) Las restricciones limitantes son;

1) La duración de tiempo de 2400 minutos.

2) La tela límite (algodón) de 500 m

b) El número máximo de pedidos de buzos (chaquetas y pantalones) que podrá entregar en una semana de trabajo es de 166 pares de chaquetas y pantalones.

Su beneficio máximo es 32,2[tex]\bar 7[/tex]·S

Step-by-step explanation:

a) El número de horas al día que trabaja el fabricante = 8 horas

Dado que la máquina puede hacer pantalones en 4 minutos y chaquetas en 10 minutos

Sea x = la cantidad de pantalones hechos en un día, e y = la cantidad de chaquetas hechas en una semana

Tenemos;

4 · x + 10 · y = 8 × 60 × 5 = 2400

x = y

Por lo tanto;

4 · x + 10 · y = 4 · x + 10 · x = 14 · x = 2400

x = 2400/14 ≈ 171,43, por lo tanto, redondeamos hacia abajo para dar;

x = 171

Por lo tanto, el fabricante fabrica 171 pantalones y 171 chaquetas durante la semana.

El material requerido para el pantalón = 171 m de algodón y 342 m de poliéster.

El material requerido para la chaqueta = 342 m algodón y 171 m poliéster

Para el material, tenemos [

a = Algodón, b = Poliéster

a + 2 · b = x

2 · a + b = y

3 · a + 3 · b = x + y = 2 · x

Dado que se requiere igual longitud de algodón y poliéster, dado por el coeficiente de ayb, y que la longitud del algodón es 500 m, que es menor que la longitud del poliéster, tenemos;

El número máximo de pantalones y chaqueta completos = 500/3 = 166,67 m, que se redondea a 166 pares

b) El número máximo de pares de pantalones y chaquetas que el fabricante podrá entregar en una semana de trabajo = 166 pares

Por tanto, el beneficio máximo será

La ganancia máxima = 166 × (S / 9 + S / 12) = 581 · S / 18 = 32.2[tex]\bar 7[/tex]·S.
