devonta throws a rock straight down off the edge of a cliff that overlooks the ocean. The distance (d) the rock falls after t seconds can be represented by the equation d = 16t^2 + 24t. if the ocean's surface is 16.4 feet below the cliff, to the nearest tenth, how many seconds will it take for the rock to hit the ocean's surface?
The rock will hit the ocean's surface in approximately 1 second.
We are given the equation d = \(16t^2 + 24t\), where d is the distance the rock falls in feet and t is the time in seconds.
We are also told that the ocean's surface is 16.4 feet below the cliff. This means that when the rock hits the ocean's surface, the distance it falls will be equal to 16.4 feet. So we can set d equal to 16.4 and solve for t:
\(16.4 = 16t^2 + 24t\)
Moving all the terms to one side, we get:
\(16t^2 + 24t - 16.4 = 0\)
Dividing both sides by 8, we get:
\(2t^2 + 3t - 2.05 = 0\)
We can solve this quadratic equation using the quadratic formula:
t\(= (-b \pm \sqrt(b^2 - 4ac)) / 2a\)
Here, a = 2, b = 3, and c = -2.05. Substituting these values, we get:
\(t = (-3 \pm \sqrt(3^2 - 4(2)(-2.05))) / (2(2))\)
Simplifying:
\(t = (-3 \pm\sqrt(33.8)) / 4\)
To the nearest tenth, the positive value of t is:
t ≈ 1.0 second
Therefore, it will take approximately 1 second for the rock to hit the ocean's surface.

a german automobile company produces cars in the united states, with some of those cars being exported to other nations and some of them being sold within the united states. if the prices of these cars increase, then
If the prices of the cars produced by the German automobile company increase, it is likely that the profit margins of the company will increase as well. This is because, with higher prices, the company can sell each car for a higher price, generating more revenue.
However, higher prices may also reduce the demand for the cars, as consumers may switch to alternative options that are cheaper. The net effect on the company's profits will depend on the relative magnitude of the increase in prices and the decrease in demand.
In terms of sales within the United States, higher prices may reduce the demand for the cars, as consumers may opt for alternative options that are cheaper.
However, if the company has a strong brand reputation and its cars are seen as high-quality, then the demand for the cars may not be significantly affected by the price increase.

Pat Statsdud is taking an economics course. Pat's exam strategy is to rely on luck for the next exam. The exam consists of 20 multiple-choice questions. Each question has four possible answers, only one of which is correct. Pat plans to guess the answer to each question without reading it. If a grade on the exam is 50% or more, Pat will pass the exam. Find the probability that Pat will pass the exam.
Answer:
0.01386 or 1.386%
Step-by-step explanation:
Each question has a binomial distribution with probability of success p =0.25 (1 correct answer out of four alternatives).
The probability of 'k' successes in n trials is given by:
\(P(x=k)=\frac{n!}{(n-k)!k!}*p^k*(1-p)^{n-k}\)
Pat will pass the exam if x ≥ 10. The probability that Pat will pass is:
\(P(pass)=P(x=10)+P(x=11)+P(x=12)+P(x=13)+P(x=14)+P(x=15)+P(x=16)+P(x=17)+P(x=18)+P(x=19)+P(x=20)\)
The probability for each number of success is:
\(P(x=10)=\frac{20!}{(20-10)!10!}*0.25^{10}*0.75^{10}=0.0099\\\\P(x=11)= \frac{20!}{(20-11)!11!}*0.25^{11}*0.75^{9}=0.0030\\\\P(x=12)=\frac{20!}{(20-12)!12!}*0.25^{12}*0.75^{8}=0.00075\\\\P(x=13)=\frac{20!}{(20-13)!13!}*0.25^{13}*0.75^{7}=0.00015\\\\P(x=14)=\frac{20!}{(20-14)!14!}*0.25^{14}*0.75^{6}=0.0000257\\\\P(x=15)=\frac{20!}{(20-15)!15!}*0.25^{15}*0.75^{5}=3.426*10^{-6}\\\\\)
\(P(x=16)=\frac{20!}{(20-16)!16!}*0.25^{16}*0.75^{4}=3.569*10^{-7}\\\\P(x=17)=\frac{20!}{(20-17)!17!}*0.25^{17}*0.75^{3}=2.799*10^{-8}\\\\P(x=18)=\frac{20!}{(20-18)!18!}*0.25^{18}*0.75^{2}=1.555*10^{-9}\\\\P(x=19)=\frac{20!}{(20-19)!19!}*0.25^{19}*0.75^{1}=5.457*10^{-11}\\\\P(x=20)=\frac{20!}{(20-20)!20!}*0.25^{20}*0.75^{0}=9.095*10^{-13}\\\\\)

-) Find the equation of the line that passes through (1,0) and (3,6).
The equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.
To find the equation of a line passing through two points, we can use the slope-intercept form of a linear equation: y = mx + b, where m is the slope of the line and b is the y-intercept.
Given points:
Point 1: (1, 0)
Point 2: (3, 6)
Step 1: Calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates:
m = (6 - 0) / (3 - 1)
m = 6 / 2
m = 3
Step 2: Substitute one of the given points and the slope into the equation y = mx + b to find the y-intercept (b).
Using Point 1 (1, 0):
0 = 3(1) + b
0 = 3 + b
b = -3
Step 3: Write the equation of the line using the slope (m) and the y-intercept (b):
y = 3x - 3
Therefore, the equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.
This equation represents a line with a slope of 3, indicating that for every increase of 1 unit in the x-coordinate, the y-coordinate increases by 3 units. The y-intercept of -3 means that the line crosses the y-axis at the point (0, -3). By substituting any x-value into the equation, we can determine the corresponding y-value on the line.
Hence, the equation of the line passing through (1, 0) and (3, 6) is y = 3x - 3.

Carson's work is correct for solving the equations.
Given that;
Carson wants to solve this system of equations.
y = x² + 5x − 6
y = x − 1
Now, We can solve first equation as;
y = x² + 5x - 6
y = x² + 5x - 6 = 0
⇒ x = - 5 ± √5² - 4×1×- 6 / 2
⇒ x = - 5 ± √25 + 24 / 2
⇒ x = - 5 ± √49 / 2
⇒ x = - 5 ± 7/2
⇒ x = - 5 + 7 / 2
⇒ x = 2/2
⇒ x = 1
⇒ x = - 5 - 7 / 2
⇒ x = - 12 / 2
⇒ x = - 6
Hence, From (ii);
⇒ y = x - 1
At x = 1;
y = 1 - 1
y = 0
At x = - 6;
y = - 6 - 1
y = - 7

What is the maximum number of miles that Joseph can drive in order for Company B to be a better buy? The company charges only for whole number mileage (not fractional increments of miles driven).
A) 125 miles
B) 149 miles
C) 150 miles
D) 151 miles
Answer:
E.The price for travelling 150 miles is same for both company.
Step-by-step explanation:
We are given that Joseph is going on a trip and he needs to rent a car.
Company A
Charge $0.25 per mile plus $50 rental fee.
Company B charges 40.45 per mile plus $20 rental fee.
A.Total distance=150 miles
Company A
Charges for 150 miles=$37.5
Total charges=37.5+50=$87.5
Company B
Charges for 150 miles==$67.5
Total charge=20+67.5=$87.5
The price for travelling 150 miles is same for both company.
But if distance greater than 150 miles such 155 miles
Company A
Total charge=$88.75
Company B
Total charges=$89.75
Company A is better deal if Joseph more than 150 miles.
If distance 145 miles
Price form company A=$86.25
Price form company B=$85.25
Company B is better deal if Joseph travel less than 150 miles.

Which shows one way to determine the factors of x3 - 12x7 - 2x + 24 by grouping?
The factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).
To determine the factors of the polynomial x^3 - 12x^2 - 2x + 24 by grouping, we can follow these steps:
Step 1: Group the terms in pairs. In this case, we can pair the first two terms and the last two terms:
(x^3 - 12x^2) + (-2x + 24)
Step 2: Factor out the greatest common factor from each pair. From the first pair, we can factor out x^2, and from the second pair, we can factor out -2:
x^2(x - 12) - 2(x - 12)
Step 3: Notice that we now have a common binomial factor of (x - 12) in both terms. Factor out this common binomial factor:
(x - 12)(x^2 - 2)
Therefore, the factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).
