Use even and odd functions to evaluate the following integral. ſ(cosa + 3x4) dx -T

Answers

Answer 1

The integral of ſ(cosa + 3x^4) dx simplifies to ∫cos(x) dx, which can be evaluated as sin(x) + C, where C is the constant of integration.To evaluate the integral of ſ(cosa + 3x^4) dx using even and odd functions, we can decompose the integrand into even and odd parts.

Let's first identify the even and odd parts of the integrand. The function cos(x) is an even function because it is symmetric with respect to the y-axis, i.e., cos(-x) = cos(x). On the other hand, the function 3x^4 is an odd function because it is symmetric with respect to the origin, i.e., (-x)^4 = x^4.

We can rewrite the integrand as a sum of even and odd functions:

cos(x) + 3x^4 = (1/2) * (cos(x) + cos(-x)) + (1/2) * (3x^4 - 3(-x)^4)

Now, we can use the properties of even and odd functions to simplify the integral. The integral of an even function over a symmetric interval is equal to twice the integral of the function over half of the interval. Similarly, the integral of an odd function over a symmetric interval is equal to zero.

So, the integral of (1/2) * (cos(x) + cos(-x)) dx is equal to (1/2) * 2 * ∫cos(x) dx, since cos(x) is an even function.

And the integral of (1/2) * (3x^4 - 3(-x)^4) dx is equal to (1/2) * 0, since 3x^4 - 3(-x)^4 is an odd function and the interval of integration is symmetric.

Therefore, the integral of ſ(cosa + 3x^4) dx simplifies to ∫cos(x) dx, which can be evaluated as sin(x) + C, where C is the constant of integration.

Carl takes out a loan which accrues interest at a flat rate of 1.96% per quarter.
what is the equivalent yearly simple interest rate?

Answers

Carl will be charged 7.84% of the initial loan amount as interest.

When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.

To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.

In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.

Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.

By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

To conduct a science experiment, it is required to decrease the temperature from 36 c at the rate of 4 c every hour. what will be the temperature 10 hours after the process begins?

Answers

To conduct the science experiment, the temperature needs to be decreased from 36°C at a rate of 4°C every hour.

So, after 1 hour, the temperature will be 36°C - 4°C = 32°C. After 2 hours, the temperature will be 32°C - 4°C = 28°C. Continuing this pattern, after 10 hours, the temperature will be 36°C - (4°C x 10) = 36°C - 40°C = -4°C.

Answers

The equation of the tangent plane to the surface at the point (u,v) = (3,U) is z = x + 34 + U.

To calculate TT, we need to find the partial derivatives of O(u,v) with respect to u and v:

TT = (∂O/∂u) x (∂O/∂v)
  = (2, 0, 8) x (0, 0, 1)
  = (-8, 0, 0)

To find n(u,v), we normalize TT:

n(u,v) = TT/|TT|
      = (-1, 0, 0)

At the point u=3, v=U, O(u,v) = (2u + 0.0 - 40, 8u) = (-34, 24).

To find the equation of the tangent plane, we first find the normal vector to the plane, which is n(u,v) = (-1, 0, 0). Then we use the point-normal form of the equation of a plane:

(-1)(x + 34) + 0(y - 24) + 0(z - U) = 0
-x - 34 + z - U = 0
z = x + 34 + U

2. A manufacturer of electronic kits has found that the mean time required for novices to assemble its new circuit tester is 3. 15 hours, with a sample standard deviation of 0. 23 hours. A consultant has developed a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device. In a test of the effectiveness of the new booklet, 25 novices require a mean of 2. 98 hours to complete the job. Assuming the population of times is normally distributed, and using the 0. 01 level of significance, should we conclude that the new booklet is effective? Determine and interpret the p-value for the test

Answers

Assuming the population of times is normally distributed, and using the 0. 01 level of significance, we can conclude that the new booklet is effective.

To determine if the new instructional booklet is effective in reducing the assembly time for novices, we will perform a one-sample t-test using the given information.

1. State the null hypothesis (H0) and the alternative hypothesis (H1):

H0: There is no difference in the mean assembly time with the new booklet (µ = 3.15 hours).

H1: The mean assembly time with the new booklet is less than 3.15 hours (µ < 3.15 hours).

2. Identify the level of significance, sample size, sample mean, and sample standard deviation:

α = 0.01

n = 25

x = 2.98 hours

s = 0.23 hours

3. Calculate the test statistic:

t = (x - µ) / (s / √n) = (2.98 - 3.15) / (0.23 / √25) = -0.17 / 0.046 = -3.70

4. Find the p-value for the test:

Using a t-distribution table or calculator, the p-value for a one-tailed test with t = -3.70 and degrees of freedom (df) = 24 is approximately 0.0005.

5. Compare the p-value with the level of significance:

Since the p-value (0.0005) is less than α (0.01), we reject the null hypothesis.

Based on the p-value, we have enough evidence to conclude that the new instructional booklet is effective in reducing the assembly time for novices at the 0.01 level of significance.

You are making a 3 foot by 3 foot coffee table with a glass top surrounded by a cherry border of uniform width. The cherry border is included in the 3 x 3 measurements. You have 5 square feet of cherry border. What should the width of the border be?

Answers

Answer:

Step-by-step explanation:

The total area of the coffee table (including the cherry border) is:

3 feet x 3 feet = 9 square feet

We know that the area of the cherry border is:

5 square feet

To find the width of the cherry border, we need to subtract the area of the glass top from the total area of the coffee table:

9 square feet - area of glass top = area of cherry border

The area of the glass top is:

(3 feet - 2x) x (3 feet - 2x)

where x is the width of the cherry border.

Since the glass top is square, we can set the two dimensions equal to each other:

(3 feet - 2x) = (3 feet - 2x)

Expanding the left-hand side, we get:

9 feet - 6x = 9 feet - 6x

Simplifying, we get:

0 = 0

This means that the width of the cherry border does not affect the area of the glass top. Therefore, we can set the area of the glass top equal to the total area of the coffee table minus the area of the cherry border:

(3 feet - 2x) x (3 feet - 2x) = 9 square feet - 5 square feet

Simplifying, we get:

(3 feet - 2x) x (3 feet - 2x) = 4 square feet

Expanding the left-hand side, we get:

9 feet^2 - 12 feet x + 4x^2 = 4 square feet

Subtracting 4 square feet from both sides, we get:

9 feet^2 - 12 feet x + 4x^2 - 4 square feet = 0

Simplifying, we get:

4x^2 - 12 feet x + 9 feet^2 - 4 square feet = 0

Using the quadratic formula, we get:

x = [12 feet ± sqrt((12 feet)^2 - 4(4)(9 feet^2 - 4 square feet))] / (2(4))

Simplifying, we get:

x = [12 feet ± sqrt(144 feet^2 - 4(4)(9 feet^2 - 4 square feet))] / 8

x = [12 feet ± sqrt(144 feet^2 - 144 feet^2 + 64 square feet)] / 8

Answers

To get the derivative of the function f(x) = (5x - 5)(√x + 3) - 1/2, we'll first need to use the product rule and then simplify the expression. The product rule states that if you have a function g(x)h(x), its derivative is g'(x)h(x) + g(x)h'(x).


Let g(x) = 5x - 5 and h(x) = √x + 3.
Step 1: the derivatives of g(x) and h(x).
g'(x) = 5 (derivative of 5x - 5)
h'(x) = 1/(2√x) (derivative of √x + 3)
Step 2: Apply the product rule.
f'(x) = g'(x)h(x) + g(x)h'(x)
f'(x) = 5(√x + 3) + (5x - 5)(1/(2√x))
Step 3: Simplify the expression.
f'(x) = 5√x + 15 + (5x - 5)/(2√x)
This is the derivative of the function f(x) = (5x - 5)(√x + 3) - 1/2. Note that none of the given answer choices match this result, so there might be a mistake in the provided options.

The trignometric equation h = (32 inches) x tan(35°) can be used to solve for the height, h, of the television screen.

We can use trigonometry to solve for the height, h, of the television screen. From the given information, we can form a right triangle with the diagonal of the television screen as the hypotenuse, and the height of the screen as one of the legs.

Since we are given the angle between the diagonal and the bottom of the television, we can use the trigonometric function tangent to relate the height and the diagonal.

The equation we can use to solve for the height is:

tan(35°) = [tex]\frac{h }{ (32 inches)}[/tex]

Rearranging this equation, we get:

h = (32 inches) x tan(35°)

Therefore, the equation that can be used to solve for the height, h, of the television screen is:

h = (32 inches) x tan(35°)

So, the equation h = (32 inches) x tan(35°) can be used to solve for the height, h, of the television screen.

Answers

The expression to show the total volume of the two boxes is:

100 + [tex]s^3[/tex] ([tex]in^3[/tex])

We can start by finding the volume of the smaller box using the formula for the volume of a cube:

Volume of smaller box = (length of one side)^3 = 100 in^3

Taking the cube root of both sides, we get:

Length of one side = ∛100 in ≈ 4.64 in

Now, we can use this value to find the volume of the larger box:

Volume of larger box = (length of one side)[tex]^3 = s^3[/tex]

The total volume of both boxes is the sum of the volume of the smaller box and the volume of the larger box:

Total volume = Volume of smaller box + Volume of larger box

Total volume = 100 in [tex]^3 + s^3[/tex]

Answers

The road with alternating white and black stripes and each 50 cm wide is 7.5 m wide.

The road consists of alternating white and black stripes

No. of white stripes = 8

As the first and last stripe is white so in between the black stripes will be 7

No. of black stripes = 7

Total no. of stripes = 15

Width of black stripe = 50 cm

Width of white stripe = 50 cm

Width of whole road = total no. of stripes × width of each stripe

Width of whole road = 15 × 50

Width of whole road = 750 cm

To convert m into cm

Now, 1 m = 100 cm

1 cm = 1/100 m

The equation that can be written to show the total length of the bandages if they are placed end-to-end is expressed as: 2(5/4) + 6/4 + 3(7/4) + 4(2) + 6(3).

How to Write an Equation for the Total Length?

In the image given above that shows a line plot for the set of data representing the length of bandages, we have:

Two 1¼ = 2(5/4)

One 1 2/4 = 6/4

Three 1¾ = 3(7/4)

Four 2 = 4(2)

Six 3 = 6(3)

Thus, the equation that will represent the total length of the bandages can be expressed as:

2(5/4) + 6/4 + 3(7/4) + 4(2) + 6(3)

Find the area of a triangle that has sides of 7, 9, and 12 inches

Answers

The area of the triangle is approximately 31.3049 square inches.

The area of a triangle can be found using the formula: A = (1/2)bh, where b is the length of the base of the triangle, and h is the height (or perpendicular distance from the base to the opposite vertex).

However, in this case, we don't have the height. Instead, we can use

Heron's formula, which only requires the lengths of the three sides of the triangle:

A = √[s(s-a)(s-b)(s-c)],

where a, b, and c are the lengths of the sides of the triangle, and s is the semiperimeter (half the perimeter):  s = (a + b + c)/2.

Using the given values, we have:

s = (7 + 9 + 12)/2 = 14

A = √[14(14-7)(14-9)(14-12)]

A = √[14(7)(5)(2)]

A = √(980)

A ≈ 31.3049 square inches

Question Two:
Kiran purchases a sofa for $1791.99 (taxes already included). The
department store offers her a promotion of 0% interest with no payments
for one year. If Kiran does not pay the amount in full within one year,
interest will be charged from the date of purchase at an annual rate of
27.93%, compounded monthly.
a) If Kiran does not make any payments, what will the department store bill
her one year after the date of purchase? Show your work. (2 marks)
b) Describe a different compounding period such that the overall cost of the
sofa is lower than if the annual interest rate were compounded monthly. Use
an example to help your explanation. (2 mark)

Answers

A. Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.

B. In this case, the overall cost of the sofa would be approximately $2,284.08

How to solve the problems

To find the initial value of the home when Zahir purchased it, we can use the compound interest formula:

Future Value = Initial Value * (1 + (interest rate))^years

Let Initial Value be P. We are given the Future Value as $548,900, the interest rate as 4.8%, and the number of years as 15.

548,900 = P * (1 + 0.048)^15

Now, we'll solve for P:

P = 548,900 / (1 + 0.048)^15

P ≈ 305,113.48

a. Future Value = Initial Value * (1 + (interest rate / number of periods))^(years * number of periods)

Initial Value = $1,791.99

Interest Rate = 27.93% (0.2793)

Number of periods = 12 (monthly)

Years = 1

Future Value = 1,791.99 * (1 + (0.2793 / 12))^(1 * 12)

Future Value ≈ 2284.33

Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.

b.  interest were compounded annually:

Future Value = Initial Value * (1 + interest rate)^years

Future Value = 1,791.99 * (1 + 0.2793)^1

Future Value ≈ 2284.08

In this case, the overall cost of the sofa would be approximately $2,284.08, which is slightly lower than if the interest were compounded monthly ($2,284.33).

iii. the integer is 37
iv. the integer has an absolute
value of 37

a) i and ii
b) i and iv
c) ii and iii
d) iii and iv

Answers

Answer:

D

Step-by-step explanation:

Because the opposite of 37 is -37, III must be true.

Given that absolute values can never be negative, II must be untrue.

Remember the definition of absolute value:

If |x| = x if x >= 0 and |x| = -x if x 0 then IV must be true.
