Y=x3 is that a function?

Answer:

[tex]u = 8[/tex]

Step-by-step explanation:

The steps are not shown. So, I will solve from scratch

Given

[tex]7(u -5) = 21[/tex]

Required

Solve, with steps

[tex]7(u -5) = 21[/tex]

Apply distributive  property

[tex]7u - 7 * 5 =21[/tex]

[tex]7u - 35 =21[/tex]

Collect like terms

[tex]7u = 35 + 21[/tex]

[tex]7u = 56[/tex]

Divide both sides by 7

[tex]\frac{7u}{7} = \frac{56}{7}[/tex]

[tex]u = 8[/tex]

Step-by-step explanation:

6x² - 4

Step-by-step explanation:

Given

4(x² - 3) + 2x² + 8 ← distribute parenthesis

= 4x² - 12 + 2x² + 8 ← collect like terms

= 6x² - 4

4(2−3)+22+8

42−12+22+8

42−12+22+8

42−4+22

42−4+22

Answer: A. Suzy made an error going from Step 1 to Step 2.

Step-by-step explanation: Following the order of operations (PEMDAS), we know that exponents are dealt with before multiplication. Suzy used the distributive property of multiplication going from step 1 to step 2, rather than working with the exponent.

Given:

w be the weight in pounds of a baby tigers.

To find:

The inequality if baby tigers can be no larger than 4 pounds.

Solution:

Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.

Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,

[tex]w\leq 4[/tex]

Therefore, the required inequality is [tex]w\leq 4[/tex].

Answer:

TQ=SR [since it is isosceles trapezoid]

6x+1.2=9x-48

48+1.2=9x-6x

3x=49.2

x=49.2/3=16.4

now

QR=3×16.4+2.5=51.7

SR=9×16.4-48=99.6

ST=4×16.4-2=63.6

TQ=6×16.4+1.2=99.6

As it's isosceles trapezoid

Now

QR=3(2)+2.5=8.5

RS=9(2)-4.8=13.2

ST=4(2)-2=6

QT=6(2)-1.2=10.8

Step-by-step explanation:

Answer:

m<3 = 108

Step-by-step explanation:

Since <1 and <2 are supplementary, the equation is:

<1 + <2 = 180

Since <1 and <3 are vertical angles. the equation is:

<1 = <3

To find m<3:

<2 + <3 = 180

72 + <3 = 180

<3 = 180 - 72

<3 = 108

The measure of angle ∠3 is 108 degrees.

Supplementary angles are those angles that sum up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

For the given situation,

∠1 and ∠2 are supplementary angles.

∠1 and ∠3 are vertical angles.

Measure of angle, m ∠2 = 72

From definition, we know that

∠1 + ∠2 = 180 (supplementary angles) ------- (1)

and

∠1 = ∠3 (vertical angles) --------- (2)

From (1) and (2),

⇒ [tex]\angle3 + \angle2 = 180[/tex]

⇒ [tex]\angle3=180-72[/tex]

⇒ [tex]\angle3=108[/tex]

Hence we can conclude that the measure of angle ∠3 is 108 degrees.

Answer:

El porcentaje de descuento fue del 10%.

Step-by-step explanation:

Para encontrar el porcentaje de descuento, puedes calcular la variación entre los dos precios ya que este será el porcentaje aplicado. Para hacerlo debes calcular la diferencia entre los dos precios restando el precio final menos el precio original y luego, debes dividir este resultado entre el precio original y multiplicar por 100:

Precio original=50

Precio final=45

((45-50)/50)*100

(-5/50)*100=-0.1*100=-10%

De acuerdo a esto, la respuesta es que el porcentaje de descuento fue del 10%.

Answer:

It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Step-by-step explanation:

In this case, the company will hire four different applicants from a group of 40 people for 4 different jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:

[tex]_{n} P_{k} = \frac{n!}{(n-k)!}[/tex] (1)

Where:

[tex]n[/tex] - Total of applicants.

[tex]k[/tex] - Selected applicants.

If we know that [tex]n = 40[/tex] and [tex]k = 4[/tex], then the number of possibilities is:

[tex]_{40}P_{4} = \frac{40!}{(40-4)!}[/tex]

[tex]_{40}P_{4} = 40\times 39 \times 38 \times 37[/tex]

[tex]_{40}P_{4} = 2193360[/tex]

There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Answer:

18 inches

Step-by-step explanation:

volume of a cuboid = length x breadth x height

the following equation can be derived from the question

let h = unknown height

1/3(24 x 15 x h) = (12 x 18 x 10)

Multiply both sides of the equation by 3

(24 x 15 x h) = (12 x 18 x 10) x 3

Divide both sides of the equation by (24 x 15)

h = 18 inches
