-multiplying conjugates
-squaring binomials
-neither
-both
Answers
Answer:
neither
Step-by-step explanation:
Take out 5 as a common factor. It will be easier to look at.
5(5c^2 + 11c + 6)
5(5C +6 )(c + 1 )
Now you can put the 5 inside.
(25c + 30)(c + 1) is one answer.
(5c + 6)(5c + 5) is another.
The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.

The ratio of three numbers is 4 : 5 : 3. The sum of the numbers is 54. List the numbers in ratio form.
Answers
Answer:
13.5 : 18 : 22.5.
Step-by-step explanation:
let the numbers be 3x , 4x and 5x
3x+ 4x + 5x = 54
12x = 54
x = 4.5
so the numbers are 3*4.5, 4 * 4.5 and 5 * 4.5
= 13.5, 18 and 22.5.
The list of the numbers in ratio form is 18 : 22.5 : 13.5
Given the ratio of three numbers as 4 : 5 : 3
Total ratio = 4 + 5 + 3
Total ratio = 12
If the sum of the numbers is 54.
For the ratio of 4:
= 4/12 * 54
= 1/3 * 54
= 18
For the ratio of 5:
= 5/12 * 54
= 270/12
= 22.5
For the ratio of 3:
= 3/12 * 54
= 1/4 * 54
= 13.5
Hence the list of the numbers in ratio form is 18 : 22.5 : 13.5

Rosetta owns a wedding photography business. For each wedding, she charges $100 plus $50 per hour of work. A linear equation that expresses the total amount of money Rosetta earns per wedding is y= 50x+100. What are the independent and dependent variables? What is the y-intercept and the slope?
a. The independent variable (z) is the amount of time Rosetta shoots photos. The dependent variable (y) is the amount, in dollars, Rosetta earns for a wedding.
b. Rosetta charges a one-time fee of $100 (this is when 2-0), so the y-intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50.
c. The independent variable (x) is the amount in dollars, Rosetta earns for a wedding. The dependent variable (y) is the amount of time Rosetta shoots photos.
d. Rosetta charges a one-time fee of $100 (this is when : 0), so they intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50.
e. The independent variable(x) is the amount of time Rosetta shoots photos.
Answers
The options are not clear enough, so i have attached it.
Answer:
A: The independent variable (x) is the amount of time Rosetta shoots photos. The dependent variable (y) is the amount, in dollars, Rosetta earns for a wedding.
Rosetta charges a one-time fee of $100 (this is when x = 0), so the y-intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50
Step-by-step explanation:
We are given the equation of total amount of money Rosetta earns per wedding as;
y = 50x + 100
Where x is number of hours.
Now, the independent variable will be x because it doesn't depend on any other variable whereas the dependent variable will be y because it depends on how many hours which is x.
Now, the y-intercept occurs when x = 0.
Thus;
y = 50(0) + 100
y = 100
Thus,she charges a one time fee of $100, so the y-intercept = $100 at x = 0.
From slope intercept equation which is;
y = mx + c and comparing with y = 50x + 100, where m is the slope, we can see that m = 50.
Thus, since she earns $50 per hour, the slope is 50.
The correct option is Option A.

A basketball is thrown upward from a height of 1.8 m at a velocity of 12 m/s. How long until it reaches the ground?
(Recall: h(t)=-4.9t^2-v_0 t+h_0, where v_0 is initial velocity and h_0 is initial height.)
Answers
V^2=U^2+2*a*x
V=0 (as it is at max height)
U=30ms^-1 (initial speed)
a=-g /-9.8ms^-2 (as it is moving against gravity)
x is the variable you want to calculate (height)
0=30^2+2*(-9.8)*x
x=-30^2/2*-9.8
x=45.92m
With these questions it's best to just memorise the suvat equations and either draw or imagine the actions involved, that was you can tell what piece of given information translates to which variable. For example; I know that I am looking for max height, so when a ball is at its highest point, it can't be moving up anymore (thus V = 0). I also know that it is moving upwards against gravity, so gravity will be decelerating the ball (therefore a=-g). In a paper, it may as for assumptions with this question, a good answer would be no air resistance or movement due to any other external forces. I hope I helped :)

The height of a model rocket, H(t), is a function of the time since it was launched, t.What is the domain of H(t)?A.0 ≤ t ≤ 324B.0 ≤ t ≤ 36C.t ≤ 324D.t > 0
Answers
Answer:
[tex]0 \le t \le 36[/tex]
Step-by-step explanation:
Given
The graph of h(t)
Required
Determine the domain
t represents the horizontal data and according to the graph;
The value of t starts at 0 (the beginning of the curve)
and ends at 36 (the end of the curve)
These values are the domain of the graph, and it can be represented as: [tex]0 \le t \le 36[/tex]
The domain of H(t) is [tex]0\leq t\leq 36[/tex]
The correct answer is option B. 0 ≤ t ≤ 36
To do this question, the main thing is to look at picture.
We know from the graph that this is a quadratic function, So t has to be less than some positive number.
{ if t → -∞, H(t) → -∞, not in the line with the actual situation}
and look at the graph, the point where H(t) equals zero, one is 0 and one is 36.
Therefore: the domain of H(t) is [tex]0\leq t\leq 36[/tex].

There is a 0.9989 probability that a randomly selected 29-year-old male lives through the year. A life insurance company charges $197 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit.
Required:
a. From the perspective of the 29-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving?
b. If the 29-year-old male purchases the policy, what is his expected value?
c. Can the insurance company expect to make a profit from many such policies? Why?
Answers
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.
We have,
a.
From the perspective of the 29-year-old male:
Surviving the year:
The monetary value is the cost of the insurance premium, which is $197.
Not surviving the year:
The monetary value is the death benefit paid out by the policy, which is $100,000.
b.
To calculate the expected value for the 29-year-old male, multiply the probability of each event by its corresponding monetary value and sum them up:
Expected Value = (Probability of Surviving * Monetary Value of Surviving) + (Probability of Not Surviving * Monetary Value of Not Surviving)
= (0.9989 * $197) + (0.0011 * $100,000)
= $306.78
c.
Expected Premium Revenue
= Probability of Surviving * Premium Amount
= 0.9989 * $197
≈ $196.49
Expected Payout
= Probability of Not Surviving * Death Benefit
= 0.0011 * $100,000
≈ $110
Profitability
= Expected Premium Revenue - Expected Payout
= $196.49 - $110
≈ $86.49
Since the expected premium revenue exceeds the expected payout, the insurance company can expect to make a profit from many such policies.
In this scenario, the insurance company can expect to make $86.49 in profit per policy.
Therefore,
a. Surviving the year: $197; Not surviving the year: $100,000
b. Expected value: $306.78
c. The insurance company can expect to make $86.49 in profit per policy.

a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insurance is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. The 29-year-old male's expected value is -$86.8013, indicating a potential loss.
c. Yes, the insurance company can expect to make a profit. The expected value is negative, meaning the company collects more in premiums than it pays out on average.
a. From the perspective of the 29-year-old male:
Surviving the year: The cost of insuring that the male will live through the year is $197.
Not surviving the year: The policy pays out a death benefit of $100,000.
b. To calculate the expected value for the 29-year-old male, we need to consider the probabilities of each event and their corresponding monetary values.
Expected Value = (Probability of surviving * Monetary value of surviving) + (Probability of not surviving * Monetary value of not surviving)
Probability of surviving = 0.9989
Monetary value of surviving = -$197 (since this represents the cost of insurance)
Probability of not surviving = 1 - Probability of surviving = 1 - 0.9989 = 0.0011
Monetary value of not surviving = $100,000
Expected Value = (0.9989 * -$197) + (0.0011 * $100,000)
Expected Value = -$196.8013 + $110
Expected Value = -$86.8013
Therefore, the expected value for the 29-year-old male is approximately -$86.8013.
c. The insurance company can expect to make a profit from many such policies because the expected value is negative (-$86.8013). The cost of insuring the male is $197, but the expected value is significantly less. This means that on average, the insurance company will collect more in premiums than it pays out in claims, resulting in a profit. The small probability of not surviving the year and the high payout of $100,000 contribute to the insurance company's ability to make a profit by spreading the risk among many policyholders.

To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(1)s + 1 = 6 + 1
(s + 1)² = 7 ( take the square root of both sides )
s + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
