A consultant advises the owners of a phone company that their profit
p each month car-be modeled by
p(x) = -50x2 + 3500x - 2500
The variable x is the average cost that a customer is charged. What
range of costs will bring in a profit of at least $40,000?
Answer:
$15.63 ≤ x ≤ $54.365
Step-by-step explanation:
Profit of the phone company is modeled by the equation,
p(x) = -50x² + 3500x - 2500
For the profit of at least $40000,
-50x² + 3500x - 2500 ≥ 40000
-50x² + 3500x ≥ 40000 + 2500
-50x² + 3500x ≥ 42500
-x² + 70x ≥ 850
x² - 70x + 850 ≤ 0
By quadratic formula,
x - intercept of the inequality will be,
x = [tex]\frac{-(-70)\pm \sqrt{(-70)^2-4(1)(850)}}{2(1)}[/tex]
x = [tex]\frac{70\pm \sqrt{1500}}{2}[/tex]
x = 15.635, 54.365
Therefore, $15.635 ≤ x ≤ $54.365 will be the range of cost for which profit will be at least $40000.
Find the angle Q and give me X
Answer:
11
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
angle q is a acute angle so it has to be 30 degrees or less. 3 times 9 equals 27 plus 1 equals 28 which is less than 30 degrees.
Solve B^7 divided by b^6
Answer:
b or b^1
Step-by-step explanation:
With dividing, you just subtract the exponents if they have the same whole number. Since the common whole number is "b", we can do 7-6 which is 1. So we would end up with b^1 which then anything to the first power equals itself, so we can simplify even more to just simply b

write an equation in point slope form that represents a line that passes by (-9,-2) and has a slope of -4
Answer:
[tex]y+2=-4(x+9)[/tex]
Step-by-step explanation:
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex]
We can write the equation by plugging in the x and y coordinates in the point (-9, -2).
[tex]y-y_1=m(x-x_1)\\y-(-2)=m(x-(-9))[/tex]
Two negatives make a positive
[tex]y+2=m(x+9)[/tex]
Now, we can plug in the slope, -4, as m.
[tex]y+2=m(x+9)\\y+2=-4(x+9)[/tex]

The student population at King Middle School is 52% female.
There are 637 girls at King Middle School. What is the total student
population King Middle School?
Answer:There are a total of 1225 students at King Middle School. If the population is 52% female, then 1225 x .52 = 637 female. 1225 - 637 = 588 male students.
Step-by-step explanation:
Answer:
1225
Step-by-step explanation:
To find the total amount of kids there are at King Middle School you do 100/52 because 52/100 is female and we are reversing the operation. 100/52 times 637 is 1225. There are a total of 1225 students and King Middle School.

The area of a rectangular wall of a barn is 144 square foot. Its length is 10 foot longer than the width. Find the length and width of the wall of the barn.
The width is ___ feet?
9514 1404 393
Answer:
width: 8 ftlength: 10 ftStep-by-step explanation:
The area is the product of length and width:
A = LW
144 = (w+10)(w)
w^2 +10w -144 = 0 . . . . . . subtract 144 and put in standard form
(w +18)(w -8) = 0 . . . . . . . . factor
w = -18 or 8 . . . . . . . values that make the factors zero, -18 is extraneous
The width of the wall is 8 ft; the length is 18 ft.
_____
Additional comment
The equation is factored by looking for factors of -144 that have a sum of 10. We can choose from the different ways 144 can be factored:
-144 = -1(144) = -2(72) = -3(48) = -4(36) = -6(24) = -8(18) = -9(16) = -12(12)
The respective sums are 143, 70, 45, 32, 18, 10, 7, 0.
So, the factors of -144 that have a sum of 10 are {-8, 18}. These are the constants that go into the binomial factors.

Jose weighed himself on monday and he weighed 170 pounds. Two weeks later he weighed 165 pounds. write a linera function in the form y=mx+b to model jose's weight loss each week, where x is the number of weeks and y is joses weight. assume a constant weight loss over the two weeks.
Answer: Hello i am here to anwser your 2 part queston! <3
Step-by-step explanation:
the linear functon is Y= -2.5x+170
after 5 weeks he will have lost 157.5 lbs!!
The linear function in the form y = mx + b to model Jose's weight loss each week is → y = - 2.5x + 170.
What is linear function? What is a mathematical function, equation and expression? The linear function is given by → y = ax + bfunction : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Jose weighed himself on Monday and he weighed 170 pounds. Two weeks later he weighed 165 pounds.
The linear function is given by → y = ax + b. We can write the slope -
{a} = (165 - 170)/(2 - 0)
{a} = - 5/ 2
{a} = - 2.5
The linear function will become -
y = -2.5x + b
At [x] = 0, the value of [y] is 170.
So, the linear function can be written as -
y = - 2.5x + 170
Therefore, the linear function in the form y = mx + b to model Jose's weight loss each week is → y = - 2.5x + 170.

please help me
Answer:
6 cm = 2.36 in (rounded to the nearest hundred)
Step-by-step explanation:
hope this helps :)
Answer:
2.36 inches
Step-by-step explanation:
1. Convert the measurement to inches.
Divide by 2.54
2. 6/2.54= 2.362
3. Look at the number in the thousandths place. If it is larger than 4, round the hundredths up. If it is 4 or smaller, it stays the same.
The number in the thousandths place is a 2, so it stays the same. 2.36
4. 2.36 inches is your answer
