An architect has designed two tunnels. Tunnel A is modeled by x2 + y2 + 30x + 56 = 0, and tunnel B is modeled by x2 – 30x + 16y – 95 = 0, where all measurements are in feet. The architect wants to verify whether a truck that is 8 feet wide and 13.5 feet high can pass through the tunnels.

Part A: Write the equation for Tunnel A in standard form and determine the conic section. Show your work.

Part B: Write the equation for Tunnel B in standard form and determine the conic section. Show your work.

Part C: Determine the maximum height of each tunnel. Is the truck able to pass through either tunnel without damage? If so, which tunnel(s) and why? Show your work.

Answers

Answer 1

The tunnel A will be damaged and truck can pass through tunnel B.

Given that, tunnel A is modeled by x² + y² + 30x + 56 = 0, and tunnel B is modeled by x² – 30x + 16y – 95 = 0.

What is the standard form of parabola equation?

The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y²= = 4ax.

Part A: x²+y²+30x+56=0

Add 15² on both the sides of a equation

That is, x²+30x+15²+y²=-56+15²

⇒ (x+15)²+y²=169

⇒ (x+15)²+y²=13²

Divide 13² on both the sides of the equation

⇒ (x+15)²/13² + y²/13² =1

Part B:

x²-30x+16y-95=0

Now, x²-30x+16y=95

Add 15² on both the sides of a equation

That is, x²-30x+15²+16y=95+15²

⇒ (x-15)²=320-16y

⇒ (x-15)²=16(20-y)

Part C:

Maximum height:

A: 13 feet

B: 20 feet

Width = 8 feet

A: x+15=8/2=4 y=12.37<13.5

B: x-15=8/2=4 y=19>13.5

Hence, the tunnel A will be damaged and truck can pass through tunnel B.

Answers

As shown in the reference graph attached hereby with the question statement, if the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds, then,

(A) During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.

(B) During (0 ≤ x ≤ 2) seconds, the height of the water balloon is increasing.

(C) During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

(D) From Part (C), it can be justified that 5 ≤ x ≤ 9.5 is the interval where the balloon's height is decreasing, and, (5 ≤ x ≤ 6) is the interval where the slope is the steepest.

As per the question statement and the reference graph attached alongside, the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds.

We  are required to determine the correct time domains for four different situations, by observing the plotted graph.

Part (A) is to determine the correct time domain where the water balloon's height remains the same.

From the graph, it is clear that, the height remains constant at (y = 70), parallel to the x-axis from the 2nd second to the 5th second. Hence, During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.

Part (B) is to determine the correct time domain where the height of the water balloon is increasing.

From the graph, it is clear that, the slope of the concerned graph rises only from [(y = 40) to (y = 70)], starring from the 0th second until the 2nd second. Hence, During (0 ≤ x ≤ 2) seconds in the time domain, , the height of the water balloon is increasing.

Part (C) is to determine the correct time domain where the height of the water balloon decreases the fastest.

From the graph, it is clear that, the graph decreases thrice, first from [(y = 70) to (y = 40)], starting at the 5th second uptil the 6th second, then from [(y = 40) to (y = 10)], starting at the 6th second uptil the 9th second and lastly, from [(y = 10) to (y = 0)], starting at the 9th second till the 9.5th second. Here, we can easily calculate that, the balloon dropped 30ft in 1 sec at the first instance, 30ft in 3 seconds at the second instance and, 10ft in 0.5 seconds.

Since, [(30/1) > (10/0.5) > (30/3)],

Or, [30 > 20 > 10],

Thus, During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

Part (D) is to determine the correct statement mentioned under it's options, with judgement based on Part (C).

Option (i) states that [(5 ≤ x ≤ 9.5) is the interval where the balloon's height is decreasing] which is true, as we can observe from the graph that the slope is decreasing during the time interval of 5 to 9.5th seconds, although at different rates at different intervals.

Option (ii) states that [(8 ≤ x ≤ 9.5) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is false, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

Option (iii) states that, [(6 ≤ x ≤ 8) is the interval where the balloon's height decreases the most] which is false, as balloons height falls the farthest by 30fts in two separate intervals, between (5 ≤ x ≤ 6) seconds and (6 ≤ x ≤ 9) seconds.

Finally, Option (iv) states that [(5 ≤ x ≤ 6) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is true, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the maximum in the shortest time period.

Answers

For a random sample of 130 mortgages with 20 delinquents on their current payment, the mean of the sampling distribution of the proportion of delinquent payments is not possible to say because population proportion is not known.

A random sample refers to a randomly selected subset of the population. In random sampling, each member of the population has an equal chance of selection, reducing the risk of selection bias. Random sampling ensures that the conclusion drawn from the sample should approximate the results obtained if entire population had been measured. The mean of the sampling distribution is the mean of the population from which results were sampled. As the population proportion (fraction of  the population with certain characteristic) is unknown, the mean cannot be determined.

Round your answer to two decimal places.AnswerHow to enter your answer (Opens in new window)KeypadKeyboard Shortcuts

Answers

The value of a machine at the end of t years with a rate of depreciation, r is given by the function:

[tex]V=C(1-r)^t[/tex]

It is required to find the age of a machine that originally costs $13,500, but is now valued at $10,419 and has a rate of depreciation of 0.12.

To do this, substitute C=13500, V=10419, and r=0.12 into the function:

[tex]\begin{gathered} 10419=13500(1-0.12)^t \\ \Rightarrow10419=13500(0.88)^t \end{gathered}[/tex]

Solve the resulting equation for t:

[tex]\begin{gathered} \text{swap the equation:} \\ \Rightarrow13500(0.88)^t=10419 \\ Divide\text{ both sides by 13500:} \\ \Rightarrow\frac{13500(0.88)^t}{13500}=\frac{10419}{13500} \\ \Rightarrow0.88^t=\frac{3473}{4500} \end{gathered}[/tex]

Take the Logarithm of both sides:

[tex]\begin{gathered} \ln(0.88^t)=\ln(\frac{3473}{4500}) \\ \Rightarrow t\cdot\ln(0.88)=\ln(\frac{3473}{4500}) \\ \Rightarrow t=\frac{\ln(\frac{3473}{4500})}{\ln(0.88)}\approx2.03 \end{gathered}[/tex]

Hence, the machine is about 2.03 years.

Answers

The ratio of the blue fish in the small tank to red fish in the large tank is 10 to 69.

Ratio is the relationship between two quantities.

Let x : y = ratio of the blue fish in the small tank to red fish in the large tank

Hence, there are x blue fish in the small tank for every y red fish in the large tank.

If in each tank, the ratio of red fish to blue fish is 3 to 4, then in each tank, in terms of x and y, the ratio is:

small tank :

red : blue = 3 : 4 = (3/4)x : x

large tank :

red : blue = 3 : 4 = y : (4/3)y

If the ratio of fish in the large tank to fish in the small tank is 46 to 5, then

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

Simplifying the proportion,

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

(7/3)y : (7/4)x = 46 : 5

Autumn has a points card for a movie theater.
She receives 40 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs at least 225 points for a free movie ticket.

Write and solve an inequality which can be used to determine v, the number of visits Autumn can make to earn her first free movie ticket.

HURRY PLEASE!!!!!!!!!!!!!!!!!

Answers

On Solving inequality  40 + 12.5 v ≥ 225, we get solution v ≥ 14.8. It means Autumn can earn movie ticket from 15 visits.

What is an inequality and how to solve it?

An inequality is a statement that compares two expressions using ≤, ≥, <, > .

We can solve an inequality by adding same number to both sides or by subtracting same number from both side. While adding or subtracting the sign of the inequality will not change.

When we multiply both sides of the inequality with a positive number then the sign of the inequality does not change, but when we multiply both sides by an negative number then the sign of inequality reverses.

Given that Autumn receives 40 points for signing up and 12.5 points for each visit to the theatre.

Let the number of visits to the theatre be v

Then points earned by v visits = v × 12.5 = 12.5 v

Total points earned = signing up points + points of v visits

⇒ Total points earned  = 40 + 12.5 v

For earning a free movie tickets the total points must be at least 225 or greater than or equal to 225

Then the inequality becomes:

40 + 12.5 v ≥ 225

Subtracting 40 from both sides

⇒ 12.5v ≥ 225-40

⇒12.5v ≥185

Multiplying both sides by 1/12.5

⇒ v ≥ 185/12.5

⇒ v ≥ 14.8

∴ The number of visits must be greater than or equal to 14.8 or nearest integer 15

∴After 15 visits, Autumn will earn a free  movie ticket

A circular wimming pool has a radius of 15 ft. There is a path all the way around that pool that is three feet wideWhat is the circumference of the outer edge of the path around the pool? Use 3.14 for pi

Answers

Given:

Radius of circular swimming pool = 15ft

Radius of the path around the pool = 3ft

radius of outer edge of the pool = 15 + 3 = 18ft

To find the circumference of the outer edge of the path around the pool, use the formula below:

[tex]C\text{ = 2}\pi\text{ r}[/tex]

where,

r = 18 ft

pi = 3.14

Thus, we have:

[tex]C\text{ = 2 }\ast\text{ 3.14 }\ast18\text{ = }113.04\text{ ft}[/tex]

Therefore, the circumference of the outer edge of the path around the pool is 113.04 ft

How many flowers spaced every 6 inches are needed to surround a circle garden with a 125 feet radius. Use three. 3.14 pi.

Answers

You would require 1,570 flowers in space of every 6inch to surround the garden with 125feet radius.

First, we need to calculate the circumference of the circle. The formula for the circumference of the circle is:

C = 2πr

If we substitute 125ft for r and use 3.14 to approximate π

we get a circumference of:

C = 2 * 3.14 * 125

C = 6.28 *125

C = 785ft

We can now convert the circumference in feet to inches as follow;

As we know that 1ft = 12inches

∴ 785ft = 12(785) inches = 9,420 inches.

To find how many flowers we need we can divide the circumference in inches by the 6 inches between flowers giving:

=[tex] 9,420in\ X \ \frac{1\ flower}{6 in} [/tex]

=[tex] \frac{9,420}{6 } \ flower [/tex]

=1,570 flowers

The dimensions of this cuboid are 2 cm, 11 cm, and 17 cm respectively.

How to calculate the volume of a geometric figure?

Mathematically, the volume of a cuboid can be calculated by using this following formula:

Volume = L × W × H

Where:

L is the length of a cuboid.W is the width of a cuboid.H is the height of a cuboid.

Substituting the given parameters into the formula, we have;

Volume = 2 × (x + 3) × (x + 9)

374 = 2 × (x² + 9x + 3x + 27)

374 = 2 × (x² + 12x + 27)

Dividing both sides by 2, we have:

187 = x² + 12x + 27

Rearranging the equation, we have:

x² + 12x + 27 - 187 = 0

x² + 12x - 160 = 0

Next, we would solve the quadratic equation by using the factorization method as follows:

x² + 12x - 160 = 0

x² + 20x - 8x - 160 = 0

x(x + 20) - 8(x + 20) = 0

(x - 8)(x + 20) = 0

x = 8 or x = -20

Since the dimensions cannot be negative, the value of x is equal to 8.

Check:

x² + 12x - 160 = 0

8² + 12(8) - 160 = 0

64 + 96 - 160 = 0

160 - 160 = 0 (True).

For the dimensions, we have:

Width = x + 3 = 8 + 3 = 11 cm.

Height = x + 9 = 8 + 9 = 17 cm.

h = [tex]\frac{1}{b-a}[/tex]

Putting here the values of a and b we get the height as,

∴ h = [tex]\frac{1}{7-(-5)}[/tex]

⇒ h = [tex]\frac{1}{7+5}[/tex]

⇒ h = [tex]\frac{1}{12}[/tex]

Hence, the height of the density function f(x) is [tex]\frac{1}{12}[/tex]

Answers

If you use excel solver for this analysis, the number of different variable cells should you use are 12

Option- C

The right answer is 12.

Given that,

There are four buses that transport children to the district's three main schools. You are aware of the price of transporting each student to each school.

Since there are four buses and three schools according to the supplied description, each bus has three school alternatives, thus 4*3=12, bearing in mind that there must be the least expensive route to transport all of the students to their schools.

There must therefore be 12 separate variable cells employed.
