find the value of x.​

Answer:

- 100

Step-by-step explanation:

x (y + z)²

= (-4) [(- 2) + (- 3)]²

= - 4 * (-5)²

= - 4 × 25

= - 100

Hope it helps ⚜

Step-by-step explanation:

we take the values given and we substitute in the equation above.

value of x=-4

y=-2

z=-3

hence we can solve for the equation above

-2(-2+-3)^2

we for everything in brackets first

(-2+-3)=-5

(-5)^2=25hence after solving we multiply by -2

-2(25)=-50

indeed that is my solution.

Answer:

The electron moved down to an energy level and has an energy of

[tex]10.92 \times 10^{-19} \textsf{J}[/tex]

Step-by-step explanation:

[tex]\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}[/tex]

[tex]\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}[/tex]

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

[tex]\triangle E=E_2-E_1[/tex]

[tex]\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1[/tex]

[tex]\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}[/tex]

[tex]\implies E_1= 10.92 \times 10^{-19}[/tex]

Answer:

The electron moved down to an energy level and has an energy of

[tex]10.92 \times 10^{-19} \textsf{J}[/tex]

Using base conversion method, 2FA.C8 base 16 can be expressed as:

To express 2FA.C8 in octal form, it is first converted to a decimal form as follows:

where:

F = 15

A = 10

C = 12

2FA.C8 = 2 × 16^2 + F × 16^1 + A × 16^0 + C × 16^-1 + 8 × 16^-2

2FA.C8 = 762.7812510 in decimal.

Then, convert 762.7812510 to octal as follows:

762 / 8 = 95 remainder 2

95 / 8 = 11 remainder 7

11 / 8 = 1 remainder 3

1 / 8 = 0 remainder 1

762 = 1372

Then;

0.78125 × 8 = 6 + 0.25

0.25 × 8 = 2 + 0

0.78125 = 0.62

Therefore, 762.78125 in decimal = 1372.628 in octal

To convert 2FA.C8 base 16 to pental form, we use its value in decimal for conversion.

Then, convert 762.7812510 to pental as follows:

762 / 5 = 152 remainder 2

152 / 5 = 30 remainder 2

30 / 5 = 6 remainder 0

6 / 5 = 1 remainder 1

1 / 5 = 0 remainder 1

Then 0.78125 to pental:

0.78125 × 5 = 3 + 0.90625

0.90625 × 5 = 4 + 0.53125

0.53125 × 5 = 2 + 0.65625

0.65625 × 5 = 3 + 0.28125

0.28125 × 5 = 1 + 0.40625

0.40625 × 5 = 2 + 0.03125

0.03125 × 5 = 0 + 0.15625

0.15625 × 5 = 0 + 0.78125

0.78125 × 5 = 3 + 0.90625

0.90625 × 5 = 4 + 0.53125

Thus, 0.78125 in decimal = 0.3423120034 in pental

Therefore, 762.78125 in decimal = 11022.3423120034 in pental.

To convert 2FA.C8 base 16 to binary form, we use its value in decimal for conversion.

Then, convert 762.7812510 to binary as follows:

762 / 2 = 381 remainder 0

381 / 2 = 190 remainder 1

190 / 2 = 95 remainder 0

95 / 2 = 47 remainder 1

47 / 2 = 23 remainder 1

23 / 2 = 11 remainder 1

11 / 2 = 5 remainder 1

5 / 2 = 2 remainder 1

2 / 2 = 1 remainder 0

1 / 2 = 0 remainder 1

Then 0.78125 to binary:

0.78125 × 2 = 1 + 0.5625

0.5625 × 2 = 1 + 0.125

0.125 × 2 = 0 + 0.25

0.25 × 2 = 0 + 0.5

0.5 × 2 = 1 + 0

0.78125 base 10 = 0.11001 base two

Therefore, 762.78125 base 10 = 1011111010.11001 base two.

Step-by-step explanation:

Answer:

x = -21/23 or 0.913 (rounded to the nearest thousandth)

Step-by-step explanation:

Step 1: Add 2/5 to both sides

    1. -1/5x - 2/5 + 2/5 = 4/3x + 1 + 2/5

    2. -1/5x = 7/5 + 4/3x

Step 2: Subtract 4/3x from both sides

    1. -1/5x - 4/3x = 7/5 + 4/3x - 4/4x

    2. -23/15x = 7/5

Step 3: Multiply both sides by 15

    1. (15)-23/15x = 7/5(15)

    2. -23x = 21

Step 4: Divide both sides by -23

    1. -23x/-23 = 21/-23

    2. x = -21/23 or 0.913 (rounded to the nearest thousandth)

Step-by-step explanation:

the dosage information bases only on age, on weight and the level of the fever. but we have no information about the fever.

so, we assume the fever is below 102.5° F.

the age is with 18 month in the valid range (0.5 to 2 years old) for the dosage.

so, all is left is to do the calculation about the weight.

24 pounds is based on the given information (1 kg ≈ 2.2 pounds) :

24/2.2 = 10.909090909... kg

this is rounded to full kg : 11 kg

the child should get 5 mg per kg, so this child has to get
