The length of the curve is \(e-e^-1.\)

The length of the parametric curve is given by the integral formula:

\(\int_{t_{1}}^{t_{2}}\sqrt{(\frac{dx}{dt})^{2}+(\frac{dy}{dt})^{2}}dt\)

The given parametric curve is: \(x=e^t + e^-t, y= 5 - 2t 0 < = t < = 1\)

The first derivative of x wrt t is:

\(\frac{dx}{dt} = e^t-e^{-t}\)

The first derivative of y wrt t is:

\(\frac{dy}{dt} = -2\)

The length of the curve is given by the following integral:

\({\int_{0}^{1}}\sqrt{(\frac{dx}{dt})^{2}+(\frac{dy}{dt})^{2}}dt\\=\int_{0}^{1}\sqrt{(e^t-e^{-t})^{2}+(-2)^{2}}dt\\=\int_{0}^{1}\sqrt{e^{2t}-2+e^{-2t}+4}dt\\=\int_{0}^{1}\sqrt{(e^{t}+e^{-t})^{2}}dt\\=\int_{0}^{1}(e^{t}+e^{-t})dt\\=[e^{t}-e^{-t}]_{0}^{1}\\=(e-e^{-1})-(1-1)= e- e^{-1}\)

Therefore, the length of the curve is \(e-e^-1.\)

The probability of obtaining 3 heads in four flips of a fair coin is 1/4.

The probability of obtaining 3 heads in four flips of a fair coin can be calculated using the binomial probability formula. The formula is:

\(P(X = k) = (n choose k) * p^k * (1 - p)^{(n - k)}\)

where P(X = k) is the probability of obtaining k successes (in this case, 3 heads), and n is the total number of trials (in this case, 4 flips).

p is the probability of success on a single trial (in this case, 0.5 since the coin is fair), and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

Plugging in the values, we get:

\(P(X = 3) = (4 choose 3) * 0.5^3 * (1 - 0.5)^{(4 - 3)}\)

= 4 * 0.125 * 0.5

= 0.25

Therefore, the probability of obtaining 3 heads in four flips of a fair coin is 1/4 or 0.25

Mother spent (4r - 8) dollars more on cherries than did the father.

An expression using numbers and related operations is called a numerical expression.

According to the question, a pound of cherries costs $4.

Mom purchased r pounds.

The price of the cherry is calculated as follows: 4r = weight x $/lb.

Father purchased 2 pounds, thus the price of the cherries is 4 (2), or $8.

We remove the smaller value from the higher value, which is 4r - 8, where r must be more than two. Given that the mother spent more money on cherries than the father, the mother's cost of cherries is a greater value.

The required value of y for the unit circle is: 2/3

The circle is defined as the locus of a point whose distance from a fixed point is constant i.e center (h, k).

The equation of the circle is given by:

(x - h)² + (y - k)² = r²

where:

h, k is the coordinate of the center of the circle on coordinate plane.

r is the radius of the circle.

Here,

Equation of the unit circle is given as,

x² + y² = 1

Now substitute the given value in the equation,

5/9 + y² = 1

y² = 1 - 5/9

y² = 4/ 9

y = √(4/9)

Step-by-step explanation:

Let's say the fixed amount Geet earns for each television is "x".

Then, for each television sold with an extended warranty, Geet earns x + $20.

So, for the 13 televisions sold with extended warranties, Geet earns a total of 13(x + $20) = 13x + $260.

We know that Geet earned $1,105 in total, so we can set up the following equation:

13x + $260 = $1,105

Solving for x, we can simplify the equation as follows:

13x = $1,105 - $260

13x = $845

x = $65

Therefore, the fixed amount Geet earns for each television is $65.

Using the concepts of mean and standard deviation, and the central limit theorem, it is found that:

a. The mean is of: 3.3

b. The standard deviation is of: 1.23.

c. They would have a mean of 3.3 and a standard deviation of 0.55.

For this problem, the mean is given by:

M = (2 + 3 + 2 + 3 + 3 + 4 + 2 + 4 + 3 + 2 + 2 + 7 + 3 + 4 + 5 + 3 + 3 + 3 + 3 + 5)/20 = 3.3

The standard deviation is:

\(S = \sqrt{\frac{(2 - 3.3)^2 + (3 - 3.3)^2 + \cdots + (3 - 3.3)^2 + (5 - 3.3)^2}{20}} = 1.23\)

It states that for distribution of sample means of size n:

So this is an inequality and can be easily solved if its opposite number is done with both the sides. There are some inequality rules which are:

1. when absolute values removed; the number in the oppostite side becomes negative and if negative then positive. And the signs are changed to its opposite sign. Like greater than to less than or vise versa.

2. When both the sides are divided or multiplied by a negative number the signs are changed.

Given the equation, y - 6 = x/4, we can rewrite the equation as:

y = x/4 + 6

For x = 12, we have:

y = 12/4 + 6 = 3 + 6

y = 9

For x = 0, we have:

y = 0/4 + 6 = 0 + 6

y = 6

For y = 4, we have:

4 = x/4 + 6

4 - 6 = x/4

-2 = x/4

-8 = x

x = -8

For y = -3, we have:

The equation of the straight line is y = -2x - 4, the value of x₁ is -1 and the value of y₁ is -2.

To find the equation of a straight line given its slope and one point, we use the point-slope form of the equation:

−y − y₁​ = m(x−x₁ )

where m is the slope of the line, and (x₁, y₁) is the given point.

In this case, m = -2 and the point is (-1, -2). So we have:

x₁ = -1

y₁ = -2

m = -2

Substituting these values into the point-slope form, we get:

y−(−2)=−2(x−(−1))

Simplifying and rearranging terms, we get the equation of the line:

y + 2 = -2x - 2

Given:

You order 1.5 pounds of turkey at the deli. You will accept the turkey if its weight is between 1.54 and 1.46 pounds.

To find:

The absolute value inequality that can be used to describe the tolerance of the weight of the turkey

Solution:

Let x be the actual weight of the turkey.

It will accepted, if its weight is between 1.54 and 1.46 pounds.

\(1.46\leq x\leq 1.54\)

Subtract 1.5 from each side.

\(1.46-1.5\leq x-1.5\leq 1.54-1.5\)

\(-0.04\leq x-1.5\leq 0.04\)

\(|x-1.5|\leq 0.04\)

Therefore, the required absolute inequality is \(|x-1.5|\leq 0.04\).

l-10+3l= 7;      l4+3l=7

==================================================

Work Shown:

|2x+3| = 7 means either 2x+3 = 7 or 2x+3 = -7

Solve each for x

2x+3 = 7

2x = 7-3

2x = 4

x = 4/2

x = 2 is one solution

Repeat for the other equation

2x+3 = -7

2x = -7-3

2x = -10

x = -10/2

x = -5 is the other solution

------

Each solution can be checked by plugging it back into the original equation and simplifying. You should get the same number on both sides

For instance, checking x = -5 leads to

|2x+3| = 7

|2(-5)+3| = 7

|-10+3| = 7

|-7| = 7

7 = 7

Which confirms x = -5. I'll let you check x = 2.

For an experiment to test the contamination of medical personnel wrist-watches at a New York hospital, the appropriate null hypothesis and alternative hypothesis would be given by this mathematical expression:

Answer:

2028 square inches

Step-by-step explanation:

The side length of the styrofoam cube measures 6 1/2 inches.

Step 1

We find the surface area of a cube

The formula is given as

Surface Area = 6a²

Where a = Side length of the cube = 6 1/2 inches

Hence,

Surface area of a cube = 6 × (6 1/2inches)²

= 253.5 square inches

Step 2

Huy is painting eight styrofoam cubes for a science project.

The total surface area that Huy will paint is calculated as:

1 styrofoam cube = 253.5 square inches

8 styrofoam cubes = x

Cross Mulitiply

x = 8 × 253.5 square inches

x = 2028 square inches

Therefore, the total surface area that Huy will paint is 2028 square inches.

The solution for [m] belongs tot he set as : m ∈ (- ∞, -227).

Given are the inequalities and it is asked to solve for [m].

The given inequalities are given as follows -

m + 13 < − 214

m > − 11112

m > − 2712

m < − 11112

m < − 2712

Now, we can write -

m + 13 < − 214

m < - 214 - 13

m < - 227

Remaining all inequalities are far far smaller than -227. So, we can say that the solution for m as : m ∈ (- ∞, -227)

Step-by-step explanation:

Given

Finding (fog)(x)

(fog)(x)  = f(g(x))

(fog)(x)  = f(x+9)

(fog)(x)  = 5(x+9)             ∵ substitute x as x+9 in the f(x)

(fog)(x)  = 5x+45

Finding (gof)(x)

(gof)(x) = g(f(x))

(gof)(x)  = g(5x)

(gof)(x)   = 5x+9                 ∵ substitute x as 5x in the g(x)

Finding (fog)(3)

(fog)(3) = f(g(3))

substitute x = 3 in the g(x)=x+9

g(x) = x+9

g(3) = 3+9

g(3) = 12

so

(fog)(3) = f(g(3)) = f(12)

now substitute x = 12 in  f(x) = 5x

f(x) = 5x

f(12) = 5(12)

f(12) = 60

Thus,

(fog)(3) = f(g(3)) = f(12) = 60
