The peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:

y = |x - 16| + 24

This equation models the roof line of Terry's house.

To model the roof line of Terry's house, we can use the concept of absolute value. The equation for an absolute value function can be written as:

y = |x - h| + k

where (h, k) represents the vertex of the absolute value graph.

In this case, the peak of the roof line is at 24 feet. Since the width of the house is 32 feet, the vertex of the absolute value graph will be at the midpoint of the width, which is 16 feet. Therefore, h = 16.

Since the peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:

y = |x - 16| + 24

This equation models the roof line of Terry's house.

The rule for g is g(x) = (-2x - 10)(√(x² - 2)) for the function g(x) = -2f(x+5).

One way to think of a function is as a rule that assigns or maps each member of a set, x, to the same value, y, known as its image.

x → Function → y

Functions are frequently denoted by a letter, such as f, g, or h. F(x) = x2+ 5 is the formula for the function that squares a number and adds a 3. A function's impact on specific values can be demonstrated using the same idea.

Given that  f(x) =  √(x² - 2)

And g(x) = -2f(x+5)

Substitute the function f(x) =  √(x² - 2) in g(x) = -2f(x+5)

g(x) = -2(√(x² - 2))(x+5)

g(x) = (-2x - 10)(√(x² - 2))

Thus, the rule for g is g(x) = (-2x - 10)(√(x² - 2)) for the function g(x) = -2f(x+5).

the probability that the randomly chosen athlete is either a football player or a basketball player is 99%.

To find the probability that the randomly chosen athlete is either a football player or a basketball player, we need to calculate the union of the probabilities.

Let's denote the probability of being a football player as P(F) and the probability of being a basketball player as P(B). We are given the following information:

P(F) = 43% = 0.43

P(B) = 56% = 0.56

P(F ∩ B) = 4% = 0.04 (since 4% play both football and basketball)

The probability that an athlete is either a football player or a basketball player can be calculated using the formula:

P(F or B) = P(F) + P(B) - P(F ∩ B)

Plugging in the values:

P(F or B) = 0.43 + 0.56 - 0.04

          = 0.99

Therefore, the probability that the randomly chosen athlete is either a football player or a basketball player is 99%.

At 11 p.m., there are approximately 24,120 freshmen and 9,000 sophomores at the prep rally, resulting in a ratio of 8:3 (freshmen to sophomores).

Starting with the initial numbers, we have 1,860 freshmen and 2,130 sophomores at noon. From 12 p.m. onward, 2020 freshmen arrive every five minutes, while 15 sophomores leave every five minutes. To find the ratio at 11 p.m., we need to calculate the number of students at that time.

Between noon and 11 p.m., there are 11 hours, or 660 minutes. In this duration, 2020 freshmen arrive every five minutes, so we have (660/5) * 2020 = 266,400 freshmen arriving.

During the same period, 15 sophomores leave every five minutes, resulting in (660/5) x15 = 1,980 sophomores leaving.

Adding the initial numbers and accounting for arrivals and departures, we have:

Total freshmen = 1,860 + 266,400 = 268,260

Total sophomores = 2,130 - 1,980 = 150

Therefore, at 11 p.m., there are approximately 268,260 freshmen and 150 sophomores at the prep rally. The ratio of freshmen to sophomores is 268,260:150, which simplifies to 8:3.

Answer:

x=8 & x=6

Step-by-step explanation:

Answer:

X= X2+48/14

Step-by-step explanation:

Let's denote the ages of the two remaining men as x and x + 3 (since one is 3 years older than the other).

We know that the average age of 6 men is 35 years. So, the sum of their ages is 6 * 35 = 210 years.

We also know that the average age of four of them is 32 years. So, the sum of their ages is 4 * 32 = 128 years.

To find the sum of the ages of the two remaining men, we subtract the sum of the ages of the four men from the sum of the ages of all six men:

210 - 128 = 82 years.

Now, we can set up an equation to solve for the ages of the remaining two men:

x + (x + 3) = 82.

Combining like terms, we get:

2x + 3 = 82.

Subtracting 3 from both sides:

2x = 79.

Dividing both sides by 2:

x = 39.5.

So, one of the remaining men is 39.5 years old, and the other is 39.5 + 3 = 42.5 years old.

The ball is approximately 50 meters from the ground after about 5.477 seconds.

To find the approximate time it takes for the ball to reach a height of 50 meters, we need to solve the quadratic equation \(f(x) = -5x^2 + 200 = 50\).

Let's set f(x) equal to 50 and solve for x:

\(-5x^2 + 200 = 50\)

Rearranging the equation, we have:

\(-5x^2 = 50 - 200\\-5x^2 = -150\)

Dividing both sides by -5:

\(x^2 = 30\)

Taking the square root of both sides:

x = ±√30

Since we are looking for the time in seconds, we only consider the positive value of x:

x ≈ √30

Using a calculator, we find that the square root of 30 is approximately 5.477.

Please note that this is an approximate value since the quadratic model provides an approximation of the ball's height and does not account for factors such as air resistance.

Venn diagram:

The percentage of students that studied mathematics = 25%
The percentage of students that studied electronics = 20%
The percentage of students that studied Communications = 55%
The percentage of students that studied both electronics and Communications subjects = 10%

P(studied Communications or electronics or both subjects)
= P(studied Communications) + P(studied electronics) - P(studied both electronics and Communications subjects)
= 55% + 20% - 10%
= 65%

Therefore, the probability that a student studied Communications or electronics or both subjects is 65%.

P(studied mathematics and Communications subjects)
= P(studied mathematics) × P(studied Communications)
= 25% × 55%
= 13.75%

Therefore, the probability that a student studied mathematics and Communications subjects is 13.75%.

Drawing a Venn diagram, we have 25% studying Mathematics (M), 20% studying Electronics (E), and 55% studying Communications (C).10% studied both Electronics and Communications.

Therefore, the percentages become as follows: M = 25% - 10% = 15% E = 20% - 10% = 10% C = 55%.

Part 2 - To obtain the probability that a student studied Communications or Electronics or both subjects

P(Communication or Electronics) = P(Communication) + P(Electronics) - P(Communication and Electronics) = 55% + 20% - 10% = 65%.

The probability that a student studied Communications or Electronics or both subjects is 65%.

Part 3 -To obtain the probability that a student studied Mathematics and Communications subjects,

P(Mathematics and Communications) = P(Mathematics) * P(Communications) = 25% * 55% = 13.75%.

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

The present value of the annuity at the end of year 7 is approximately $47,069.08.

To calculate the present value of an ordinary annuity, we can use the formula:

PV = PMT * [(1 - (1 + r)⁻ⁿ) / r],

where PV is the present value, PMT is the annual payment, r is the interest rate per period, and n is the number of periods.

In this case, the annual payment is $4,500, the interest rate is 8%, and the number of periods is 16. However, the payments start at the end of year 8 and continue until the end of year 23, which means there is a delay of 7 years.

Using the formula, the present value at the end of year 7 can be calculated as:

The two factors of the quadratic polynomial x^2 + 3/2 x - 1 are:

(x - 2) and (x + 0.5)

We have a quadratic polynomial, sadly we don't have the options for the factors, so we will find the two factors of our polynomial.

To find the factors first we need to solve the quadratic equation:

x² + (3/2)*x - 1 = 0

Using the quadratic formula we get the solutions:

\(x = \frac{-3/2 \pm \sqrt{(3/2)^2 -4*1*(-1)} }{2*-1} \\\\x = \frac{-3/2 \pm 2.5 }{-2}\)

Then the two solutions are:

x = (-3/2 + 2.5)/-2 = -0.5

x = (-3/2 - 2.5)/-2 = 2

Then we can factorize our polynomial as:

p(x) = (x - 2)*(x - (-0.5))

p(x) = (x - 2)*(x + 0.5)

So the two factors are:

(x - 2) and (x + 0.5)
