Answer:

Henry's friend referring to the disadvantage of Privacy.

Step-by-step explanation:

The main disadvantage of cloud storage is:

Your data is no longer in your physical storage while you are using a cloud service. So, who is responsible for ensuring that information is secure? This is a grey field which is still being worked out.

So, Henry's friend referring to the disadvantage of Privacy.

Answer:

E. The data is not under the owner’s direct control.

Answer:

[tex]2abcosC = 37[/tex]

Step-by-step explanation:

Given

[tex]a^2 + b^2 - 2abcosC = c^2[/tex]

Required

[tex]2abcosC[/tex]

[tex]a^2 + b^2 - 2abcosC = c^2[/tex]

Add [tex]2abcosC[/tex] to both sides

[tex]a^2 + b^2 - 2abcosC+2abcosC = c^2+2abcosC[/tex]

[tex]a^2 + b^2 = c^2+2abcosC[/tex]

Subtract [tex]c^2[/tex] from both sides

[tex]a^2 + b^2 -c^2= c^2 -c^2+2abcosC[/tex]

[tex]a^2 + b^2 -c^2= 2abcosC[/tex]

From the attachment:

[tex]a = 4[/tex] [tex]b = 5[/tex] and [tex]c = 2[/tex]

So, we have:

[tex]4^2 + 5^2 -2^2= 2abcosC[/tex]

[tex]16 + 25 -4= 2abcosC[/tex]

[tex]37= 2abcosC[/tex]

i.e.

[tex]2abcosC = 37[/tex]

Answer:

x= - 23/4

Step-by-step explanation:

Add  9  to both sides of the equation:

3x -9 = 7x +14

3x- 9 + 9 = 7x +14 +9

Simplify:

3x -9 + 9 = 7x +14 +9

3x = 7x +14 +9

3x =7x +14 +9

Subtract 7x from both sides of the equation:

3x= 7x +23

3x -7x = 7x +23 - 7x

Simplify Again:

3x -7x = 7x +23 -7x

-4x =23

Combine like terms:

-4x =23

Divide both sides of the equation by the same terms:

14x/ 14  = 23/ -4

Cancel terms that are both the numerator and the denominator:

x= - 23/- 4

Answer:

x= - 23/4

Answer:

3

Step-by-step explanation:

2 / (2/3) = 2 * 3/2 = 6/2 = 3

Answer:

y = 20x + 280

Step-by-step explanation:

The linear equation that represent your account balance is as follows:

Your friend

y = 25(6) + 250

= 400

And,

You

400 = m(6) + 280

6m = 400 - 280

6m = 120

m = 20

Now the equation of the account balance is

y = 20x + 280

Hence, the linear equation that represent your account balance is y = 20x + 280

Answer:

16x² + 2x + 9

Step-by-step explanation:

To evaluate h(- 2x) , substitute x = - 2x into h(x), that is

h(- 2x)

= 4(- 2x)² - (- 2x) + 9

= 4(4x²) + 2x + 9

= 16x² + 2x + 9

Answer:

Step-by-step explanation:

by inspection.. ( looking at the graph)  we can see that the slope is down hill. so it's going to be negative and also  slope = rise / run     [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me  (-3,1) and (2,-3)   you tell me if that looks right... if it does .. then the rise / run is 4/5  and this is a negative slope  sooo  

- 4/5

:)

Answer:

According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)

... or factors of 992(+/-).  you can test by direct substitution.  No positive values are roots ... try 1, 1332, but as x increases so does y ...  so there are no positive roots.

  Roots, means y = 0 ...  so (x + 10)^3  = 8 ... take cube root ... x + 10 = 2  .. x = -8

x = -8 is a root

Testing other negatives and the y values are not zero but tend toward - infinity.

So the only real zero is x = -8

Answer:

it helps you

Step-by-step explanation:

this is for y = (x-10)^3 - 8

According to the integral root theorem the only possible real, integral zeros are +/- factors of (10*3 - 8)

... or factors of 992(+/-). you can test by direct substitution. No positive values are roots ... try 1, 1332, but as x increases so does y ... so there are no positive roots.

Roots, means y = 0 ... so (x + 10)^3 = 8 ... take cube root ... x + 10 = 2 .. x = -8

x = -8 is a root

Testing other negatives and the y values are not zero but tend toward - infinity.

So the only real zero is x = -8

Similarly for y = (x + 7)^3 +2 = 0

(x + 7)^3 = -2

x + 7 = cube root (-2)

x = -7 + cube root (-2) <<< the only real root

Answer:

y = 3x - 6

Step-by-step explanation:

slope intercept form is: y = mx + b

m is your slope, so figure it out by doing rise/run

you rise 3, over one which is 3/1, but simplifies to 3

b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6

therefore, your answer is: y = 3x - 6

Answer: See explanation

Step-by-step explanation:

The possible lengths of the third side would be:

✓hypotenuse = (✓5² + 8²)

= ✓(25 + 64)

= ✓89

= 9.4

OR

8² - 5² = side²

side² = 64 - 25

side² = 39

Side = ✓39

Side = 6.24

Step-by-step explanation:

Answer:

The coordinates of the Midpoint of AB will be: (1/2, 5)

Step-by-step explanation:

Given the points

Finding the midpoint between (-2, 6) and (3, 4)

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:6\right),\:\left(x_2,\:y_2\right)=\left(3,\:4\right)[/tex]

[tex]M.P=\left(\frac{3-2}{2},\:\frac{4+6}{2}\right)[/tex]

        [tex]=\left(\frac{1}{2},\:5\right)[/tex]

Therefore, the coordinates of the Midpoint of AB will be: (1/2, 5)

Answer:

I will do the first one for you 115/24

Step-by-step explanation:

First find the prime number is of the number on the bottom of the fraction

Second after finding the prime numbers multiple all the times number starting with the bigger number’s prime number, and if the other prime number have a pair dont add them into equation. Ex 8-2 2 2 and 4-2 2 the 8 has 3 (2s) cancelling out the 4’s( 2s) other ex. 6-2 3 and 18- 2 3 3 the 18 has a 2 and 3 cancelling out the 6’s 2 and 3 making it multiple 2x3x3

Third after finding this number at step (2) this is the number at the bottom of the fraction making it easy to do any equations on it
