A 16-bit register contains a value. the value 0x75a2 is written into it. can the original value be recovered (yes or no)?

1 answer:

3 0

The given value of 0x75a2 is the hexadecimal representation of the value or number.

The base of the HEX system is 16, and the first 16 numbers are named
0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f

In the decimal system, the given number is
(2 x 10⁰) + (10 x 16¹) + (5 x 16²) + (7 x 16³)
= 2 + 160 + 1280 + 28672
= 30114

Answer:
The original value can be recovered, and it is 30114.

Ray Of Light [21]

Answer:

She either trained recently in an area with a high elevation, participated in blood doping, or has polycythemia vera.

Step-by-step explanation:

Michaela has a hematocrit value of 59%, which is well above the normal range, according to research that has found that athletes reduce hematocrit levels in the form of sports anemia.

This sports anemia is caused by increasing plasma volume into RBCs and increasing the total mass of hemoglobin.

But Michella has a significant increase in hematocrit rather than the normal range.

so hematocrit value suggest blood dopping which has resultted into increased hematocrit level

Please solve using elimination.

melamori03 [73]

Answer:

x = -19/3 y = 10 write as an ordered pair (-19/3, -10)

Step-by-step explanation:

Step 1: 'Elimination' is done through adding or subtracting. You want to add the two equations together to get rid of one of the variables.

Since the x values have coefficients with opposite signs (-9 and 9), add the two functions together. The result is...

-2y = 20 { -9x + 9x = 0, so x is gone, 4y + (-6y) = -2y, 17 + 3 = 20 }

Step 2: Now solve for the remaining variable, in this case, 'y'

-2y = 20 (divide both sides by -2 to isolate the variable)

y = -10

Step 3: Plug the value for 'y' into one of the original equations to find 'x'

-9x + 4(-10) = 17 ('y' becomes -10)

-9x - 40 = 17 { 4(-10) = -40 } (now add 40 to both sides)

-9x = 57 (divide both sides by -9 to isolate 'x' )

x = -57/9 (now reduce, both are multiples of 3, so divide 3 out)

x = -19/3 ( -57/3 = -19, 9/3 = 3 )

Margaret drove to a business appointment at 80 mph. Her average speed on the return trip was 70 mph. The return trip took her 1/

Gnoma [55]

Margaret traveled 80 miles to the appointment.

Step-by-step explanation:

Given,

Speed while driving for appointment = 80 mph

Speed while coming back = 70 mph

Let,

x be the time taken for the trip

y be the distance covered

Distance = Speed*Time

y = 80x Eqn 1

Time taken in return trip = x+1/7

y = 70(x+1/7)

$y=70x+10$ Eqn 2

Putting value of y from Eqn 1 in Eqn 2

$80x=70x+10\\80x-70x=10\\10x=10$

Dividing both sides by 10

$\frac{10x}{10}=\frac{10}{10}$

x = 1 hour

Putting x = 1 in Eqn 1

$y=80(1) \\y=80$

Margaret traveled 80 miles to the appointment.

Write the following in slope-intercept form.

Umnica [9.8K]

Answer:

$\huge\boxed{y=4x-7}$

Step-by-step explanation:

Linear equations will always be in the form $y=mx+b$ , where m is the slope and b is the y-intercept

Since we know nothing about this equation, other than the fact that there are two points in it, we must find the slope and the y-intercept.

Luckily, we have two points to work with. We know that the slope between two points will be the change in y divided by the change in x ( $\frac{\Delta y}{\Delta x}$ ), so we can use the two points given to us to find both changes.

The y value goes from 1 to 17, which is a $17-1=16$ change.

The x value goes from 2 to 6, which is a $6-2=4$ change.

Now that we know both changes, we can divide the change in y by the change in x.

$\frac{16}{4}=4$

Now that we know the slope (4), we can plug it into our equation ( $y=mx+b$ ).

$y=4x+b$

Now all we need to do is find the y-intercept. Since we know the slope and one of the points the line passes through, we can find the y-intercept by substituting in the values of x and y. Let's use the point (2, 1).
