Problem A
Usually the number of bits in a byte is 8 or 16 or 32 and recently 64. You don't have to write a formula to restrict it to this number of bits. You are not asked to do so. The general formula is 2^n - 1 for the problem of Millie and her golden keys. Somehow the system can be made to choose the right number of bits. Apple IIe s for example, used 8 bits and there was a location that told the processor that fact.

2^n - 1 <<<<< Answer

Problem B
In this case n = 4
2^n - 1 = 2^4 - 1 = 16 - 1 = 15

Pythagorean theorem to determine if a triangle with sides 2 ft,5ft,4ft is a right triangle

What is the similarity ratio of the smaller to the larger prisms? Enter your answer as a:b

Answers

The similarity ratio, I believe, is 2:3.

Because the lengths are 6 and 9 (2:3), the widths are 8 and 12 (2:3), and the heights are 6 and 4 (2:3).

Answer:

6:9>2:3

Step-by-step explanation:

In order to do this, you just have to equalize the ratio you just need to search for the same sides, so the 6 side is similar with the 9 side on the larger, and then the 8 to the 12 and the 4 to the 6, so you just equalize any of those equal we will use the 8 and 12:

8:12

Now we just reduce it with the same:

4:6

2:3

So the ratio would be 2:3.

What is the equation in slope-intercept form of the linear function represented by the table? x y –6 –18 –1 –8 4 2 9 12

Answers

Using the 2-point form of the equation for a line, you can write the equation as
y = (y₂ -y₁)/(x₂ -x₁)×(x -x₁) +y₁
If we let (x₁, y₁) = (4, 2) and (x₂, y₂) = (9, 12) this becomes
y = (12 -2)/(9 -4)×(x -4) +2
y = (10/5)×(x -4) +2
y = 2x -6

The equation in slope-intercept form of the given function is ...
y = 2x -6

Answer: y=2x-6

Hypotenuse is 74 and one leg is 24

Answers

The Pythagorean theorem applies. If the sides are designated by "a" and "b", and the hypotenuse is designated by "c", then that theorem tells you
c² = a² + b²

Filling in your numbers, we can solve for b.
74² = 24² + b²
74² - 24² = b² = 4900
b = √4900 = 70

The length of the third side is 70.

22x+70=17x-95 show step by step please

Answers

[tex]22x + 70 = 17x - 95[/tex]
Move variables to the left by adding their opposites to both sides. Eliminate the opposites.

[tex]22x - 17x + 70 = - 95[/tex]
Move constants to the right by adding their opposites to both sides. Eliminate the opposites.

[tex]22x - 17x = - 95 - 70[/tex]
Collect the like terms by subtracting their coefficients and numbers.

[tex]5x = - 95 - 70[/tex]
Calculate the sum or difference. Extract the negative sign from the expression. Add the numbers.

[tex]5x = - 165[/tex]
Divide both sides of the equation by 5 and calculate the quotient.

[tex]x = - 33[/tex]

Answer:

Value of x is -33.

Step-by-step explanation:

[tex] \sf22x+70=17x-95 [/tex]

We combine x term together. In this equation there are two extra 22x and 17x and 17x is right hand side and we have to shift it left hand side so we have to change sign. 17x is a positive number so we have to shift in left hand side so it convert into negative number means - 17x.

[tex]\sf22x - 17x=-95 - 70[/tex]

Now, we combine next terms together and in right hand side we shift -70. Because in left hand side 70 is a positive number then we have to shift it right hand side so it change into negative.

[tex] \sf5x = - 165[/tex]

We write 5x because we subtract 22 with 17 and in right inside we write minus 165 because we add - 95 and -70. we can't subtract minus 95 and -70 because in front of the both of number there is a sign of minus.

Remember :-

- and - = + + and - = -- and + = -

[tex]\sf x = \dfrac{ - 165}{5} [/tex]

We divide -165 by 5. Because in Left hand side 5x is in multiple so we shift it Right hand side and it turns into divide.

[tex] \sf \:x = - 33[/tex]

Now, we get value of x is -33.

Verification :-

Put values of x -33

22x+70

22×(-33) +70

= -726 + 70

= -656

Now, in R.H.S

17x-95

17×(-33) -95

= - 561 - 95

= - 656

L.H.S = R.H.S

Hence, proved

Note :-

L.H.S = Left hand side

R.H.S = Right hand side

Evaluate 7i^4-12i^2
-5
19
19i

Answers

The answer is 19
Hope this helps

The powers of i repeat every four terms, so i⁴ equals 1 and i² equals -1. The result of the evaluation is 19.

To evaluate the expression 7i⁴-12i². In complex numbers, i is the imaginary unit with the property that i² = -1. The powers of i repeat every four terms:

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

Using these properties, we can simplify the expression:

7i⁴ is 7 times 1, which equals 7.

-12i² is -12 times -1, which equals 12.

Adding these together, we get 7 + 12 = 19.

Therefore, the evaluated expression is 19.

Solve for the variable 10/8=n/10

Answers

Answer: 50/4 or 12.5

Step-by-step explanation:

We can cross-multiply in this situation.

Cross-multiplying...

[tex]\frac{10}{8} = \frac{n}{10}[/tex]

8n = 10(10) = 100

In other words, we multiply the denominator of 10/8, which is 8, by the numerator of n/10, which is n, and vice-versa.

Dividing 8 on both sides....

n = 100/8 = 50/4 = 12.5

If YB = ZA find the value of X and the length of YB

Answers

Since ZA and YB are equal in length and the two lines are parallel to each other.

Also, we can see that YZ and AB are perpendicular to both ZA and YB, thus

YZ = AB

16x - 4 = 4 - 4x

16x + 4x = 4 + 4

20x = 8

x= 8/20 = 2/5

YB = ZA = 20x - 5 = 20(2/5) - 5 = 3

Thus, the value of x is 2/5 and length of YB is 3 units.

So, the correct answer is option A
