Which statement describes values of x and y such that could be an irrational number? A. The value of x is zero, and the value of y is an integer less than zero. B. The value of x is the square root of an integer, and the value of y is an integer greater than zero. C. The value of x is an integer less than zero, and the value of y is an integer greater than zero. D. The value of x is a square root that can be simplified to an integer, and the value of y is an integer less than zero.​

Answer:

A) 8

Step-by-step explanation:

The remainder when f(x) = x⁴ + 0x³ - 5x² - 6x - 10 is divided by x - 3 is 18.

Factor theorem states that if x - a is a factor of f(x) then f(a) = 0.If f(a) ≠ 0 then x - a is not a factor of f(x).

To determine the remainder of f(x) = x⁴ + 0x³ - 5x² - 6x - 10 when divided by x - 3 which is x - 3 = 0 or x = 3 we have to replace the value of x in f(x).

∴ f(x) = x⁴ + 0x³ - 5x² - 6x - 10.

f(3) =  (3)⁴ + 0(3)³ - 5(3)² - 6(3) - 10.

f(3) = 81 + 0 - 45 - 18.

f(3) = 18.

So, the remainder is 18.

Answer:

39%

Step-by-step explanation:

It is given that 35 apartments have balconies in them.

While 55 apartments do not have balconies in them.

Total number of balconies is the sum of the apartments. i.e. 35 + 55

                                                                                             = 90 apartments

Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.

i.e.

[tex]$=\frac{35}{90}$[/tex]

= 0.38888888

Multiplying by 100, we get

= 0.388888 x 100

= 38.8888 %

= 39 %

Answer:

Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).

Step-by-step explanation:

One endpoint of (4,-12), length of 5 units.

Four possible pairs:

Add 5 to x, keep y: (4+5,-12) = (9,-12).

Subtract 5 from x, keep y: (4-5,-12) = (-1,-12).

Keep x, add 5 to y: (4,-12+5) = (4,-7)

Keep x, subtract 5 from y: (4,-12-5) = (4,-17)

Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).

Answer:

(7/4)(2)(2)=7

Step-by-step explanation:

Answer:

z = 1.75xy

Step-by-step explanation:

Given z varies jointly as x and y then the equation relating them is

z = kxy ← k is the constant of variation

To find k use the condition z = 7 when x = 2 and y = 2, then

7 = k × 2 × 2 = 4k ( divide both sides by 4 )

1.75 = k

z = 1.75xy ← equation of variation

Answer:

Also BC = 12

B......6......D......6......C

Now, AC = 2.

A can be either left of C or right of C

If A is left of C , AB = 12-2 = 10 (Correct)

If A is right of C AB = 12 +2 = 14 (Incorrect)

So the points placing is as below

B......6......D....4....A..2..C

Length of segment AD = 4

Answer:

C

Step-by-step explanation:

It’s convenient that there are only two x values you need to check, -2 and 2. Just insert it to see what y is appropriate.

x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)

x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)

So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.

A isn’t in the solution set either with -5 < 4.

C is in the solution set with 5 > 4.

Answer:

3x^2=81

x²=81/3

x=√27=3√3

Step-by-step explanation:

3x²=81

With this we have to square root both sides to find the value of x.

[tex] \sqrt{3 {x}^{2} } = \sqrt{81} [/tex]

So the x will cancel the square root sign so;

[tex]3x = \sqrt{81} [/tex]

And now we have to find the square root of 81 which is 9, because when we multiply 9 by 9 we are going to be get 81 so the square of 9 is 81 and the square root of 81 is 9

So;

[tex]3x = 9[/tex]

And then we divide both sides by 3 to find the value of x ;

[tex] \frac{3x}{3} = \frac{9}{3} [/tex]

[tex]x = \frac{9}{3} [/tex]

[tex]x = 3[/tex]

Answer:

X = 2, 4, 6, 7, 9

Y = 29, 33, 37, 39, 43

Step-by-step explanation:

Given a best fit line of :

y = 2x + 25

Take points X as :

X = 2, 4, 6, 7, 9

X = 2

y = 2(2) + 25 = 4 + 25 = 29

X = 4

y = 2(4) + 25 = 8 + 25 = 33

X = 6

y = 2(6) + 25 = 12 + 25 = 37

X = 7

y = 2(7) + 25 = 14 + 25 = 39

X = 9

y = 2(9) + 25 = 18 + 25 = 43

Answer:

24 m³

Step-by-step explanation:

Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question

Assuming it's breadth is 2 m.

Assuming it's length is 4 m.

Assuming it's height is 3 m

Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³

24 m

Now what you'd do is substitute your values for my assumed values.. Cheers
