Consider the function f : R→R
given by f(x) = x^(4) - 32 x^(2)
Find the minimum and and maximum values (absolute) of f over the interval [3,5]. Provide the exact values. Minimum value a Maximum value.

Answers

Answer 1

The minimum value of f(x) over the interval [3,5] is -512 and the maximum value is 225.

To find the minimum and maximum values of the function f(x) = x^(4) - 32 x^(2) over the interval [3,5], we can use the following steps:

1. Find the first derivative of the function: f'(x) = 4x^(3) - 64x
2. Set the first derivative equal to zero to find the critical points: 4x^(3) - 64x = 0
3. Solve for x to find the critical points: x = 0, x = 4√2, x = -4√2
4. Check the value of the function at the critical points and at the endpoints of the interval to find the minimum and maximum values.
5. The minimum value occurs at x = 4√2, where f(4√2) = (4√2)^(4) - 32(4√2)^(2) = -512
6. The maximum value occurs at x = 5, where f(5) = 5^(4) - 32(5)^(2) = 225
7. Therefore, the minimum value is -512 and the maximum value is 225.

The least value of f(x) over the interval [3,5] is -512 and the largest value is 225.

Using the rational root theorem, list out all possibl f(x)=-x+14x^(3)-18x^(2)-4x^(5)-26x^(4)+8

Answers

The possible rational roots of f(x) are ±1, ±2, ±4, ±8, ±1/2, and ±1/4.

The Rational Root Theorem states that if a polynomial [tex]f(x) = anxn + an-1xn-1 + ... + a1x + a0[/tex] has a rational root, then it must be of the form p/q, where p is a factor of the constant term a0 and q is a factor of the leading coefficient an.

For the given polynomial [tex]f(x) = -x + 14x3 - 18x2 - 4x5 - 26x4 + 8[/tex], the constant term is 8 and the leading coefficient is -4.

The factors of 8 are ±1, ±2, ±4, and ±8. The factors of -4 are ±1, ±2, and ±4.

Therefore, the possible rational roots of f(x) are:

p/q = ±1/1, ±2/1, ±4/1, ±8/1, ±1/2, ±2/2, ±4/2, ±8/2, ±1/4, ±2/4, ±4/4, ±8/4

Simplifying gives us the possible rational roots:

What is the total surface area of the rectangular prism shown?

Answers

Hence, the total surface area of the rectangular prism is 736 in².

Provide an example to help people understand what surface area is.

A 3D object's surface area is calculated as the total of all of its faces. For instance, if we wanted to figure out how much paint we would need to paint a cube, we would use the cube's surface area.

To calculate the total surface area of the rectangular prism, we need to find the area of each of its six faces and add them together.

The area of the top and bottom faces, which are identical, is:

Length x Breadth = 16 in x 8 in = 128 in².

The area of the front and back faces, which are also identical, is:

Height x Breadth = 10 in x 8 in = 80 in².

The area of the left and right faces, which are also identical, is:

Height x Length = 10 in x 16 in = 160 in².

Therefore, the total surface area of the rectangular prism is:

2(Length x Breadth) + 2(Height x Breadth) + 2(Height x Length)

= 2(16 in x 8 in) + 2(10 in x 8 in) + 2(10 in x 16 in)

= 256 in² + 160 in² + 320 in²

= 736 in²

In this case, a = 1, b = -3, and c = 4. Substituting these values into the formula, we get:

x = (3 ± sqrt((-3)^2 - 4(1)(4))) / 2(1)

x = (3 ± sqrt(9 - 16)) / 2

x = (3 ± sqrt(-7)) / 2

Since the square root of a negative number is not a real number, the solutions to the quadratic equation are complex numbers. Therefore, the answer is:

Ten pounds of mixed birdseed sells for $6.70 per pound. The mixture is obtained from two kinds of birdseed, with one variety priced at $5.77 per pound and the other at $8.87 per pound. How many pounds of each variety of birdseed are used in the mixture?

Answers

The composition of the mixture is: 7.323 pounds of the variety priced at $5.77 per pound and 2.677 pounds of the variety priced at $8.87 per pound.

To solve this problem, we can use a system of equations. Let x be the number of pounds of the first variety of birdseed, and y be the number of pounds of the second variety of birdseed.

The first equation will represent the total weight of the mixture:
x + y = 10

The second equation will represent the total cost of the mixture:
5.77x + 8.87y = 6.70(10)

Now we can use the elimination method to solve for one of the variables. Multiply the first equation by -5.77 to eliminate the x variable:
-5.77x - 5.77y = -57.7

Add this equation to the second equation:
3.1y = 8.3

Solve for y:
y = 2.677

Now we can plug this value back into the first equation to solve for x:
x + 2.677 = 10
x = 7.323

So, there are 7.323 pounds of the first variety of birdseed and 2.677 pounds of the second variety of birdseed in the mixture.

Dave is driving from Portola Ave. To Springs Street. Portola Ave. Is marked as "A" and Springs Street is marked as "E".

He takes 3 miles to go to the ice store. (C)

He drives back to Portola Ave. Where his house is.

From A to C is 6 miles

After a few hours he drives to the market (D)

he spends 25 minutes there and drives back home which is 24 miles.

He stops by a gas station (B) when he goes back home. He takes 10 minutes there.

Then when he’s home, he packs items which takes 55 minutes.

Then he drives to springs street (E)

This takes 40 miles.

He realized that he forgot something at the market, so he drives back to the market which is 5 miles away.

Then he drives back to Springs Street

After he enters the airport (E) he takes 25 minutes to have his luggage checked and boards the plane. Then the plane immediately takes off.

It is 12:45pm when Dave is about to go the ice store.

When he rests for a few hours after coming back from ice store he rests for 2 hours.

What time does the plane take off?

Answers

When he rests for a few hours after coming back from ice-store he rests for 2 hours the time the plane takes off is 9:10 pm.

Total distance traveled is 151 miles.

Dave spends 25 + 10 + 55 + 25 = 115 minutes (or 1 hour and 55 minutes) on stops.

Dave rests for 2 hours.

To calculate the time the plane takes off, we need to add up all the time Dave spends on driving, stops, and rests, and then add that time to the time he starts (12:45 pm).

Time to drive from A to C and back to A: 2 * 6 / 60 = 0.2 hours

Time to drive from A to C to D to B to A: (6 + 24 + 24 + 3) / 60 = 0.95 hours

Time to drive from A to C to D to home to E to market to E: (6 + 24 + 24 + 40 + 5 + 5) / 60 = 2.33 hours

Time to rest: 2 hours

Total time spent: 0.2 + 0.95 + 2.33 + 1.92 = 5.4 hours

Time of departure: 12:45 pm + 5.4 hours = 6:25 pm

Adding 45 minutes for the luggage check and boarding, the plane takes off at 6:25 pm + 0.45 hours = 7:10 pm

Adding another 2 hours for the time zone difference, the plane takes off at 7:10 pm + 2 hours = 9:10 pm.

If the aspect ratio of a white board is 16:9 and the width is 64in, what is the height of the white board?

Answers

The height of the white board for the given aspect ratio is found as 36 in.

Explain about the aspect ratio?A proportional association among an image's height and width is known as an aspect ratio. It essentially describes the contour of a picture. Aspect ratios are expressed as a width-to-height formula, such as 3:2. A square image, for instance, has a 1:1 aspect ratio because its width and height are equal. Aspect ratio, in its most basic form, is the proportion between an image's width and height. That affects how readers compose your picture and how huge it will be, which is why it's so crucial.

Aspect ratio of a white board = 16:9 .

Width = 64 in

Let the height be 'h'.

So, using proportions.

16/9 = 64/h

h = 64*9 /16

h = 36

Thus, the height of the white board for the given aspect ratio is found as 36 in.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.97 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.​

Answers

Answer:

The discount is 15% of the cost of the meal before the discount, so the discounted cost is:

Discounted cost = $78.97 - 0.15($78.97) = $67.12

Now we need to calculate the tip on the cost before the discount. The tip is 20% of the cost before the discount, so the tip amount is:

Tip = 0.20($78.97) = $15.79

Adding the discounted cost and the tip, we get the total cost of the meal:

Total cost = $67.12 + $15.79 = $82.91

Therefore, the total cost of the meal, including the discount and tip, is $82.91.

The three possible forms of any positive odd integer, as required.

According to the Euclid Division Lemma, for any two positive integers a and b, there exist unique integers q and r such that a = bq + r where 0 ≤ r < b.

We can use this lemma to show that any positive odd integer is of the form 6q + 1, 6q + 3, or 6q + 5 where q is some integer.

Let a be any positive odd integer and let b = 6. By the Euclid Division Lemma, we can write a = 6q + r where 0 ≤ r < 6. Since a is odd, r cannot be an even number. Therefore, r can only take on the values of 1, 3, or 5.

Thus, we can write a as:

a = 6q + 1
a = 6q + 3
a = 6q + 5

There are a total of 32 possible sequences because there are two alternatives for each stage. Since there are more than seven distinct ways to mount the stairs, the priestess can do so every day for a week.

How many ways are there of ascending the steps?

(a) Every day, the priestess at the temple of Horus must climb a flight of five stairs, which she can do by taking one or two steps at a time. The amount of ways she can up the stairs on any given day can be represented by a binary digit, where 1 denotes a two-step ascent and 0 denotes a one-step ascent. For each of the five steps, for instance, 00101 reflects the order of her one- and two-step climbs.

How many ways are there of ascending the grand staircase?

(b) The same regulations apply. The entire number of potential sequences, using the same binary digit format, is 213 = 8,192. There are therefore more than 365 possible ways to mount the grand staircase, allowing the priest to do so every day for a whole year.

In conclusion, the number of alternative binary sequences, where each digit denotes a one- or two-step climb, may be used to determine the number of ways the priestess can ascend the five-step flight of stairs and the number of ways the priest can ascend the thirteen-step grand staircase.

Answers

Answer: The correct response is "Interest rates vary between lenders and can drastically change the monthly payment."

The interest rate is one of the most important things to consider when shopping around for loans because it determines the cost of borrowing money. Different lenders offer different interest rates, and even a small difference in interest rates can have a big impact on the total cost of the loan. A higher interest rate will result in a higher monthly payment, and a longer repayment period, which can make the loan more expensive overall. Therefore, it is important to shop around and compare interest rates from different lenders to find the best deal.

A linear equation is a mathematical equation that represents a straight line on a graph. It is an equation in which the highest power of the variable is one. A general linear equation can be represented as y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.

Linear equations can be solved algebraically using techniques like substitution or elimination, and they can be used to model real-world situations involving linear relationships.

If an equation is true for all values of x, then it is called an identity. To check if an equation is an identity, we can simplify both sides of the equation using algebraic methods and see if they are equal. If they are, then the equation is an identity.

On the other hand, if an equation is true for no values of x, then it is a contradiction. In this case, we can also simplify both sides of the equation using algebraic methods and see if they are not equal. If they are not, then the equation is a contradiction.

If neither of these cases applies, then the equation may be true for some values of x but not for others.

Answers

The volume of the parallelepiped is 15.

To determine the volume of the parallelepiped with one vertex at the origin and the three vertices adjacent to it at (3,1,-1), (6,7,1), and (-6,8,9), we need to find the scalar triple product of the three vectors formed by these vertices. The scalar triple product is given by the determinant of the matrix formed by the three vectors:
\[ \begin{vmatrix} 3 & 1 & -1 \\ 6 & 7 & 1 \\ -6 & 8 & 9 \end{vmatrix} \]
Expanding the determinant, we get:
\[ \begin{aligned} \text { Volume } &=3\left( \begin{vmatrix} 7 & 1 \\ 8 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 1 \\ -6 & 9 \end{vmatrix} \right)-1\left( \begin{vmatrix} 6 & 7 \\ -6 & 8 \end{vmatrix} \right) \\ &=3(63-8)-1(54+6)-1(48+42) \\ &=165-60-90 \\ &=15 \end{aligned} \]

For the second right angled triangle, we have to find the length of the altitude.

Using Pythagoras theorem,

17² = b² + 12²

b² = 17² - 12²

b² = 145

b = √145 = 12.04159 ≈ 12

Hence the length of and b are 9.4 and 12 respectively.

Given f(x)=3x+4 and g(x)=2x^2−5x−9, find a) f[g(x)] b) g[f(x)] c) f[f(x)] d) f/g
and the domain of it written using interval notation.

Answers

To find the composite functions, we simply substitute one function into the other.

For example, f[g(x)] means we substitute g(x) into f(x) wherever there is an x. So, f[g(x)] = 3(g(x)) + 4 = 3(2x^2 − 5x − 9) + 4 = 6x^2 − 15x − 23.Similarly, we can find the other composite functions: g[f(x)] = 2(f(x))^2 − 5(f(x)) − 9 = 2(3x+4)^2 − 5(3x+4) − 9 = 18x^2 + 7x - 7f[f(x)] = 3(f(x)) + 4 = 3(3x+4) + 4 = 9x + 16

For the last part, f/g means we divide f(x) by g(x):f/g = (3x+4)/(2x^2−5x−9)The domain of this function is all real numbers except for the values of x that make the denominator equal to zero.

To find these values, we set the denominator equal to zero and solve for x:2x^2−5x−9 = 0(2x+3)(x-3) = 0x = -3/2, 3 So the domain of f/g is (-∞, -3/2) ∪ (-3/2, 3) ∪ (3, ∞) in interval notation.
