A company finds that if it charges x dollars for a cell phone, it can expect to sell 1000-2x phones
Answers
The x-intercepts of the situation means that the company generates no revenue when the cost is $0 and when the cost is $500
Interpreting the x-intercepts of the situation?From the question, we have the following parameters that can be used in our computation:
r(x) = x(1000 - 2x)
To calculate the x-intercepts of the situation, we set the function to 0
So, we have
x(1000 - 2x) = 0
This means that
x = 0 or 1000 - 2x = 0
When solved for x, we have
x = 0 or x = 500
This means that the company generates no revenue when the cost is $0 and when the cost is $500

ten minutes later airplane 2 lands with a rate of descent of -97/8 feet per second. which airplane had the fastest rate during its landing?
Answers
Airplane 1 had the fastest rate of descent during its landing.
To compare the rates of descent of the two airplanes, we need to convert both rates to a common unit of measurement. Let's convert both rates to feet per minute (ft/min) to make the comparison easier.
Airplane 1 had a rate of descent of -130 ft/s, which is equivalent to:
-130 ft/s × 60 s/min = -7800 ft/min
Airplane 2 had a rate of descent of -97/8 ft/s, which is equivalent to:
(-97/8) ft/s × 60 s/min = -729.375 ft/min
Comparing these two rates, we can see that Airplane 1 had the faster rate of descent during its landing:
-7800 ft/min (Airplane 1) > -729.375 ft/min (Airplane 2)
Therefore, Airplane 1 had the fastest rate of descent during its landing.

Answers
Answer:
proof below
Step-by-step explanation:
∠A ≅ ∠B
as ACB is a triangle
if ∠A ≅ ∠B then AC = BC
and CD ⊥ AB
so ∠CDA = ∠CDB = 90
now in ΔADC ---> ∠A + ∠CDA + ∠ACD = 180
lets assume ∠A = x = ∠B
x + 90 + ∠ACD = 180
∠ACD = 180 - 90 - x
∠ACD = 90 - x
now in ΔCDB ---> ∠B + ∠CDB + ∠BCD = 180
x + 90 + ∠BCD = 180
∠BCD = 180 - 90 - x
∠BCD = 90 - x
As ∠ACD = ∠BCD
CD bisects ∠ACB
Indirectly to proof:-

Among those have scholoarship, what is the percentage of studens who are senior
Answers
Answer:
27.27% of the students with scolarship are seniors.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which
P(B|A) is the probability of event B happening, given that A happened.
\(P(A \cap B)\) is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has scolarship
Event B: Is a senior
15% are senior, and of those, 40% have scolarship. So
\(P(A \cap B) = 0.15*0.4 = 0.06\)
Probability of a scolarship:
15% of 40%(seniors)
30% of 25%(juniors)
20% of 25%(sophmores).
10% of 35%(freshmen). So
\(P(A) = 0.15*0.4 + 0.3*0.25 + 0.2*0.25 + 0.1*0.35 = 0.22\)
Percentage:
\(P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.22} = 0.2727\)
0.2727*100 = 27.27%
27.27% of the students with scolarship are seniors.

on the last 5 quizzes, marco has earned a total of 21 out of 25 possible points. if he has a perfect score on the next several quizzes, exactly how many points will he need to bring up his average up to 90%
Answers
Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.
The mean of a data-set is the sum of all observations divided by the number of observations.
In this problem:
In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is \(\frac{21}{25} = 0.84\).In the next n observations, mean of 1.Hence, the mean is:
\(M = \frac{0.84(5) + n}{5 + n} = \frac{4.2 + n}{5 + n}\)
We want the mean to be of 0.9, thus:
\(M = 0.9\)
\(\frac{4.2 + n}{5 + n} = 0.9\)
\(4.2 + n = 0.9n + 4.5\)
\(0.1n = 0.3\)
\(n = \frac{0.3}{0.1}\)
\(n = 3\)
3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans
Answers
We know that he used 5/6 gallons of gas per hour of driving.
So, the total amount of gas he used is 5/6 * x.
We also know that he used a total of 5 3/4 gallons of gas.
So, we can set up the equation:
5/6 * x = 5 3/4
To solve for x, we can first convert 5 3/4 to an improper fraction:
5 3/4 = 23/4
Then, we can multiply both sides of the equation by the reciprocal of 5/6:
x = (5 3/4) / (5/6)
x = (23/4) / (5/6)
x = (23/4) * (6/5)
x = 27.6/4
x = 6.9
Therefore, Pablo was driving for a total of 6.9 hours.

Which of the following is a factor of 24x^6 - 1029y^3?
Answers
The factors of (24x⁶ - 1029y³) are 3, (2x² - 7x), (4x⁴ +14x²y+49y²)
Factors of Polynomials:When a polynomial is factored, its prime factorization is used to break it down into the product of two or more other polynomials. Polynomials may be easily simplified with the use of factoring.
When a polynomial is factored, its factors are expressed as the polynomial's product. Finding the zeros of the polynomial expression or the values of the variables in the supplied expression are both made possible by factoring polynomials.
Here we have
24x⁶ - 1029y³
Take 3 as common
=> 3(8x⁶ - 343y³)
As we know 8 = 2³ and 343 = 7³
=> 3[(2x²)³ - (7y)³]
From the algebraic identities
a³-b³ = (a-b)(a²+ab+b²)Take a = 2x² , b = 7y and apply above formula
=> 3[(2x² - 7x)((2x²)²+(2x²)(7y)+(7y)²)]
=> 3 [ (2x² - 7x) (4x⁴ +14x²y+49y²)]
Therefore,
(24x⁶ - 1029y³) = 3 (2x² - 7x) (4x⁴ +14x²y+49y²)
Therefore,
The factors of (24x⁶ - 1029y³) are 3, (2x² - 7x), (4x⁴ +14x²y+49y²)
