Sunrise, a bed-and-breakfast hotel, charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night. Craig wants to book a hotel for 5 nights.

Answers

Answer:

Sunrise $450 Bright Eyes $475

Step-by-step explanation:

Let x= number of days

Sunrise:

(25 + 85x)= total cost

(25+85(5))= $450

Bright Eyes:

(95x)= total cost

(95(5))= $475

The Bright eyes hotel would be more cost efficient than the Sunrise hotel.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Sunrise, a bed-and-breakfast hotel, that charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night.

The total cost for 5 nights at Sunrise hotel would be -

C(s) = 25 + 85 x 5 = $450

The total cost for 5 nights at Bright eyes hotel would be -

C(b) = 95 x 5 = $475

Therefore, the Bright eyes hotel would be more cost efficient than the Sunrise hotel.

Z varies jointly with x, and y, and z=7 when x= 2, y= 2
pleasee I need an answer now!!

Answers

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

The coordinates of one endpoint of a line segment are (4, −12). The length of the segment is 5 units. Determine four coordinate pairs that could serve as the other endpoint of the given line segment. Enter all four coordinate pairs in the box using a comma to separate each pair. For example: (0, 0), (1, 1), (2, 2), (3, 3)

Answers

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:

Step-by-step explanation:

Rewrite this quadratic as a^2 + 3a - 7 = 0.  The coefficients are {1, 3, -7}.  The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.

Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.

What is the remainder if f(x) = x^4- 5x2 - 6x - 10 is divided by x - 3?
A. 8
B. 44
C. -46
D. 224

Answers

Answer:

A) 8

Step-by-step explanation:

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

What is factor theorem?

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.

Solve the quadratic equation.
3x^2=81​

Answers

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]

A clear box has the shape of a rectangular prism and is filled with sand. Find the volume if the box

Answers

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
