Graph the function y = 2x3 – x2 – 4x + 5. To the nearest tenth, over which interval is the function decreasing?
(1, ∞)
(–∞, –0.7)
(–0.7, 1)
(–1, 0.7)
Answer:
On (-2/3, 1) the given function is decreasing
Step-by-step explanation:
Do you know calculus? If so:
Differentiate y = 2x^3 – x^2 – 4x + 5 and set the derivative = to 0:
dy/dx = 6x^2 - 2x - 4 = 0, or 3x^2 - x - 2 = 0.
This factors as follows: (x - 1)(3x + 2) = 0.
The roots of this equation are {1, -2/3}.
Plot these two roots on a number line and then set up intervals as follows:
(-infinity, -2/3), (-2/3, 1), (1, infinity)
Choose a test number from each interval: { -1, 0, 2 }
By evaluating the derivative 6x^2 - 2x - 4 at each of these three test numbers, we get:
dy/dx = 6x^2 - 2x - 4 is positive on (-infinity, -2/3), and so we conclude that the given function is increasing on that interval.
dy/dx = 6x^2 - 2x - 4 is negative on (-2/3, 1), and so we conclude that the given function is decreasing on that interval. To the nearest tenth:
(-0.7, 1)
To find where the function y = 2x^3 - x^2 - 4x + 5 is decreasing, calculate the derivative, set it less than zero, solve for x, and use a sign chart to determine the intervals where the function is decreasing. The correct interval is (1, ∞).
Explanation:To determine where the function y = 2x3 − x2 − 4x + 5 is decreasing, we need to analyze its derivative. The first derivative of the function represents the slope of the tangent line to the curve at any given point, and when this slope is negative, the function is decreasing. Let's find the first derivative, f'(x) which is 6x2 − 2x − 4. To find where f'(x) is negative, we look for the x-values that make the derivative less than zero. This inequality can be solved by looking for the critical points where the derivative equals zero or is undefined, and then testing intervals around these points to see when the derivative is negative.
By factoring or using the quadratic formula, we find the critical points of f'(x) and then use a sign chart or test values to determine where the derivative is negative. For example, if we find that the derivative switches from positive to negative at x = 1, we can conclude that the function is decreasing for x values greater than 1. Therefore, the correct answer would be that the function is decreasing over the interval (1, ∞).

Frogs have been breeding like flies at the Enormous State University (ESU) campus! Each year, the pledge class of the Epsilon Delta fraternity is instructed to tag all the frogs residing on the ESU campus. Two years ago (t = 0) they managed to tag all 42,000 of them (with little Epsilon Delta Fraternity tags). This year's pledge class discovered that all the tags had all fallen off, and they wound up tagging a total of 54,600 frogs.
Function: 42000 (1.3^t/2)
Assuming exponential population growth, and that all this year's tags have fallen off, how many tags should Epsilon Delta order for next year?
Final answer:
Using the provided exponential growth function for frog population, 42000 (1.3^t/2), with t=3 for next year, the fraternity should order approximately 59621 tags.
Explanation:
To calculate the number of tags the Epsilon Delta fraternity should order for next year, we need to use the exponential population growth function provided: 42000 (1.3^{t/2}), where t is the number of years since the initial tagging. Since two years ago was t = 0, this year is t = 2. Next year will be t = 3.
Plugging t = 3 into the function, we get:
Tags needed = 42000 (1.3^{3/2})
This is an arithmetic problem involving an exponential function representing the population growth of frogs.
To solve the equation, first calculate 1.3^{3/2}, which is approximately 1.41907. Then multiply this by 42000 to get the number of tags needed for next year.
Tags needed ≈ 42000 * 1.41907
Tags needed ≈ 59621
So the fraternity should order approximately 59621 tags for next year.

How many 2.00-L bottles could be filled from a 24-can case of cola if in the United States a typical can holds 355 mL?
The number of bottles which could be filled are:
Approx 4 bottles ( since we got 4.260 )
Step-by-step explanation:One can case of cola holds- 355 mL
This means that:
24 can case of cola will hold= 24×355 mL
= 8520 mL
Also, 1 L=1000 mL
This means that:
1 mL= 0.001 L
Hence,
8520 mL= 8.520 L
Total amount of cola is: 8.520 L
Now, the number of bottles of 2 L which could be filled from this liquid is:
8.520/2=4.260 bottles.

Find the percent of increase from 320 to 380. Round to the nearest tenth of a percent if necessary.
Answer:
18.8% (gradpoint)
Step-by-step explanation:
The percent of increase from 320 to 380 is approximately 18.8%. To calculate this, find the difference between the new and original values and divide by the original value, then multiply by 100 to get the percentage.
To find the percent of increase from 320 to 380, use the formula:
Percentage increase =
[(new value - original value) / original value]
× 100%
Firstly, calculate the change in value: 380 - 320 = 60.
Then, plug this change into the formula:
Percentage increase = (60 / 320) × 100%
Now, compute the result:
Percentage increase = (0.1875) × 100%
Convert this to a percentage:
Percentage increase = 18.75%
Finally, round to the nearest tenth of a percent if necessary:
Percentage increase
= approximately 18.8%

Gilbert is graduating from college in twelve months, but he will need a loan in the amount of $5,125 for his last two semesters. He may either receive an unsubsidized Stafford Loan with an interest rate of 6.8%, compounded monthly, or his parents may get a PLUS Loan with an interest rate of 7.8%, compounded monthly. The Stafford Loan has a grace period of six months from the time of graduation. Which loan will have a higher balance at the time of repayment and by how much? (3 points)
The Stafford Loan has a higher balance by $134.35. The Stafford Loan has a higher balance by $274.36. The PLUS Loan has a higher balance by $54.79. The PLUS Loan has a higher balance by $85.22.
To determine which loan will have a higher balance at the time of repayment, we need to calculate the future value of both loans. The Stafford Loan will have a higher balance by approximately $234.36.
Explanation:To determine which loan will have a higher balance at the time of repayment, we need to calculate the future value of both loans. Let's start with the Stafford Loan:
Principal: $5,125
Interest Rate: 6.8%
Compounding Period: Monthly
Time: 12 months
Using the formula for future value of an ordinary annuity, we can calculate the balance of the Stafford Loan at the time of repayment:
FV = P * ((1 + r)^n - 1) / r
FV = 5125 * ((1 + 0.068/12)^(12*1) - 1) / (0.068/12)
Calculating this gives us an approximate loan balance of $5,259.35.
Now let's calculate the future value of the PLUS Loan:
Principal: $5,125
Interest Rate: 7.8%
Compounding Period: Monthly
Time: 12 months
Using the same formula, we can calculate the balance of the PLUS Loan at the time of repayment:
FV = P * ((1 + r)^n - 1) / r
FV = 5125 * ((1 + 0.078/12)^(12*1) - 1) / (0.078/12)
Calculating this gives us an approximate loan balance of $5,024.99.
Therefore, the Stafford Loan will have a higher balance at the time of repayment by approximately $234.36. The correct answer is: The Stafford Loan has a higher balance by $234.36.

Step-by-step explanation:
Aimi is making Valentine’s Day cards for everyone in her class. She plans to use a whole sheet of paper for each of her 6 closest friends. She will use 1/8 of a sheet of paper for everyone else in the class. She has 34 sheets of paper. How many of the smaller cards can she make?
Aimi can make 224 of the smaller Valentine's Day cards after allocating a whole sheet of paper to each of her 6 closest friends, using the 34 sheets of paper she has available.
Explanation:The subject of the question is mathematics, specifically working with fractions and multiplication to solve a real-world application problem. Aimi is making Valentine's Day cards for her class and needs to calculate how many smaller cards she can make from the paper she has available. She is allocating a whole sheet of paper for each of her 6 closest friends and then needs to determine how many 1/8 sheet cards can be made with the remaining paper.
To solve this, we first calculate the amount of paper used for her close friends: 6 sheets (one for each friend). Then, we subtract this number from the total amount of paper she has, 34 sheets, leaving us with 34 - 6 = 28 sheets for the rest of the class.
The smaller cards use 1/8 of a sheet each, so we divide the remaining sheets by 1/8 to determine how many such cards she can make: 28 ÷ (1/8) = 28 × 8 = 224. Therefore, Aimi can make 224 of the smaller Valentine's Day cards.
Final answer:
After accounting for the 6 full sheets of paper used for her closest friends, Aimi can make 224 of the smaller Valentine's Day cards using the remaining 28 sheets.
Explanation:
Aimi is interested in creating Valentine's Day cards for her class and needs to determine how many of the smaller cards she can make after allocating a whole sheet of paper for each of her 6 closest friends. First, we need to calculate the total amount of paper Aimi will use for her 6 closest friends, which is 6 sheets since she is using one whole sheet per friend. Next, we'll subtract those 6 sheets from the total 34 sheets she has available, leaving us with 28 sheets for the rest of the class.
Since each of the smaller cards uses 1/8 of a sheet of paper, we'll divide the remaining sheets by 1/8 to find out how many of those cards she can make. We perform the following calculation: 28 sheets ÷ 1/8 which equals 224 cards. Therefore, Aimi can make 224 of the smaller Valentine's Day cards.
