Solving the quadratic function, it is found that the range is of:
between 200 and 250; inclusive
The profit for x tours is modeled by the following equation:
[tex]p(x) = -2x^2 + 900x - 40000[/tex]
It is concave down, so the monthly profit will be of at least $60,000 between the two roots when [tex]p(x) = 60000[/tex]. Thus:
[tex]60000 = -2x^2 + 900x - 40000[/tex]
[tex]2x^2 - 900x + 10000 = 0[/tex]
Simplifying by 2:
[tex]x^2 - 450x + 50000 = 0[/tex]
Which has [tex]a = 1, b = -450, c = 50000[/tex]
Then:
[tex]\Delta = (-450)^2 - 4(1)(50000) = 2500[/tex]
[tex]x_{1} = \frac{-(-450) + \sqrt{2500}}{2} = 250[/tex]
[tex]x_{2} = \frac{-(-450) - \sqrt{2500}}{2} = 200[/tex]
At least $60,000 includes $60,000, thus the interval is inclusive, and the correct option is:
between 200 and 250; inclusive

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
The total cost of her travel is £349
Beena is on holiday for 2 weeks.
The cost of the villa is 650 euros per week.
i.e. 2*650
=1300 euros
=1300/1.12
=£1160.71
While on holiday, Beena has 7 art lessons.
The cost of each art lesson is 45 euros.
i.e. total cost = 7*45
=315
=315/1.12
=£281.25
[Using an exchange rate of 1.12 euros = £1]
Hence, The total cost of Beena's travel, villa and art lessons = £1790.97

I need to solve for x
Answer:
x = 10
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles. The two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles.
In the given problem, the exterior angle is < JUV, and its corresponding remote interior angles are < V and < W.
Establish the following equation according to the exterior angle theorem:
< V + < W = < JUV
88° + (5x + 1)° = (14x - 1)°
Solve for x algebraically:
88° + 5x + 1 = 14x - 1
89 + 5x = 14x - 1
89 + 1 + 5x = 14x - 1 + 1
90 + 5x = 14x
90 + 5x - 5x = 14x - 5x
90 = 9x
90/9 = 9x/9
10 = x
Therefore, the value of x = 10.

What is the equation of the line that passes through the point (-6, -7) and has a slope of 0
Answer:
x = - 6
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis with equation
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, - 7 ) with x- coordinate - 6 , then
x = - 6 ← equation of line

We conclude that the question illustrates associative property.
Transpose for p
w = p + cg
Make h the subject
m = r - h + 4d
The result of making the required variable the subject in both equation are :
p = w - cgh = - (m - r - 4d)Making p the subject in w = p + cg :
w = p + cg
Subtract cg from bith sides
w - cg = p + cg - cg
p = w - cg
2.)
Make h the subject m = r - h + 4d
m = r - h + 4d
Subtract r from both sides
m - r = r - h + 4d - r
m - r = - h + 4d
Subtract 4d from both sides
m - r - 4d = - h
Divide both sides by - 1
h = - (m - r - 4d)

What is the value of x in the equation 3(2x + 8) = 0? (4 points) Group of answer choices −8 −4 4 8
Answer:
-4
Step-by-step explanation:
Start with 3(2x + 8) = 0.
Distribute the 3 to the 2x and 8 in the parentheses.
That will give you 6x + 24 = 0.
Subtract 24 from both sides, which will get x by itself and leave you with 6x = -24.
Divide both sides by 6 to get x = -4.
That is your answer.

Answer:
B) $1.25
Step-by-step explanation:
1. First, let's take two points. In this case, we're going to take (4,5) and (8,10). We took 2 points, so we can verify the unit rate/cost per pound of pineapple.
2. To find the cost per pound of pineapple, we have to divide the cost (the y-coordinates) by the pound (x-coordinates)
5 ÷ 4 = 1.2510 ÷ 8 = 1.253. Now, since we can verify with 2 coordinates that the cost per pound is $1.25, the answer is B) $1.25.
