Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The 1st one is:

\(3x-17+ x+40+2x-5=180\\6x+18=180\\6x=162\\x=27\)

The 2nd one is:

\(103-x+2x=6x-7\\103+x=6x-7\\103=5x-7\\110=5x\\x=22\)

Answer:

Step-by-step explanation:

First (the left)

3x - 17 + x + 40 + 2x - 5 = 180

6x + 18 = 180

6x = 162

x = 27

Second(the right)

6x - 7 = 2x + 103 -x

6x - 7 = x + 103

5x - 7 = 103

5x = 110

x = 22

Check:

6(22) - 7 = 132 - 7 = 125

103 - 22 = 81

2(22) = 44

missing angle next to exterior is 55

The answer is below

Step-by-step explanation:

Given that:

Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.

the mean weight of discarded plastic for all household is given by:

\(\mu_x=\mu = 1.93\ pounds\)

The standard deviation of discarded plastic for all household is given by:

\(\sigma_x=\frac{\sigma}{\sqrt{n} } =\frac{1.08}{\sqrt{62} }=0.137\ pounds\)

The confidence (c) = 90% = 0.9

α = 1 - c = 1 - 0.9 = 0.1

α/2= 0.1/2 = 0.05

The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e. \(z_\frac{\alpha}{2}=z_{0.05}=1.645\)

The margin of error (E) = \(z_{0.05}\frac{\sigma}{\sqrt{n} }=1.645*\frac{1.03}{\sqrt{62} }= 0.2256\)

The confidence interval = \(\mu \pm E=1.93 \pm 0.2256=(1.7044,2.1556)\)

We are 90% confidence that the value is between 1,7044 and 2.1556

Step-by-step explanation:

Perimeter = 2(length + width)

Solve: Plug in given information:

-Chetan K

Step 1: Let's recall that the angles given are alternate exterior angles and thus congruent which means the two angles have the same measure.

Step 2: Upon saying that, we are ready to wirite our equation to solve for x, as follows:

8x + 4 = 9x - 11

Like terms

8x - 9x = -11 - 4

-x = - 15

Multiplying by -1 at both sides:

x = 15

Step 3: Now we are ready to find that both angles are congruent and equal:

8 * 15 + 4 = 9 * 15 - 11

120 + 4 = 135 - 11

? = ?

The equation of the circle in standard form is (x - 3)²+ y² = 1.

The standard form of the equation of a circle is:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is its radius.

This equation represents all points in the xy-plane that are equidistant from the center (h, k) of the circle. The squared terms (x - h)² and (y - k)² represent the distances between the center and any point (x, y) on the circle, and r² is the squared length of the radius of the circle.

In the given question,

The center of the circle is (3, 0), and the radius extends to the point (4, 0), which means the radius has a length of 1 unit.

Substituting the values of the center and radius into the standard form equation of a circle, we get:

(x - 3)² + (y - 0)² = 1²

Simplifying, we get:

(x - 3)² + y² = 1

Therefore, the equation of the circle in standard form is:

(x - 3)² + y² = 1.

The value of f(g(x)) is x^2 + 1/x

A function is an expression that describes the relationship between an independent variable and dependent variable.

Given the functions;

f(x) =

\( \sqrt[3]{x} \)

g(x) =

\( \frac{ x+ 1}{ {x}^{3} } \)

How to determine the function

Substitute the value do x as the value of the function g(x)

f(g(x)) =

\( \sqrt[3]{ \frac{x + 1}{ {x}^{3} } } \)

Find the cube root of the expression

f(g(x)) =

\( \frac{ {x}^{3} + {1}^{3} }{x} \)

Find the cube of the values

f(g(x)) =

\( \frac{ {x}^{3} + 1 }{x} \)

Divide through by x, we have;

f(g(x)) = x^2 + 1/x

Thus, the value of f(g(x)) is x^2 + 1/x

The diver collected water samples at every 3 meters, starting from 5 meters below the water surface, up to a final depth of 35 meters.

We can find the number of samples collected by dividing the total depth range by the distance between each sample and then adding 1 to include the first sample.

The total depth range is:

35 m - 5 m = 30 m

The distance between each sample is 3 m, so the number of samples is:

(30 m) / (3 m/sample) + 1 = 10 + 1 = 11

Therefore, the diver collected a total of 11 water samples.

a) The estimated model relating annual salary to firm sales and market value, in equation form, is: Salary = 4.6209 + 0.1621 * log(sales) + 0.1067 * log(mktval), where log denotes the natural logarithm.

b) Calculating this expression will give us the expected salary according to the model. If the expected salary is higher than $500,000, then your friend would be asking too much.

a) The estimated model relating annual salary to firm sales and market value, in equation form, is:

Salary = 4.6209 + 0.1621 * log(sales) + 0.1067 * log(mktval)

where log denotes the natural logarithm.

b) To determine if your friend would be asking too much for an annual salary of $500,000, we need to plug the values of firm sales and market value into the model and calculate the expected salary.

Using the given values:

- Firm sales (sales) = $5,000,000

- Market value (mktval) = $20,000,000

We first need to take the logarithm of the sales and market value:

log(sales) = log(5,000,000)

log(mktval) = log(20,000,000)

Then, we can substitute these values into the equation:

Expected Salary = 4.6209 + 0.1621 * log(5,000,000) + 0.1067 * log(20,000,000)

Calculating this expression will give us the expected salary according to the model. If the expected salary is higher than $500,000, then your friend would be asking too much.

Note: Make sure to use the natural logarithm (ln) in the calculations.

The correct statement is: "The domains of g(x) and f(x) are the same, but their ranges are not the same."

The statement "The domains of g(x) and f(x) are not the same, and their ranges are also not the same" is correct. In general, when considering functions g(x) and f(x) derived from a parent function, the transformations applied to the parent function can affect both the domain and the range. The domain of a function refers to the set of all possible input values, while the range represents the set of all possible output values. Through transformations such as shifts, stretches, compressions, or reflections, the domain and range of a function can be altered. Therefore, it is possible for the domains and ranges of g(x) and f(x) to differ from each other and from the parent function.

To determine which of the given sets is a subspace, we need to check if they satisfy the three conditions for being a subspace: closure under addition, closure under scalar multiplication, and containing the zero vector.

(i) W1 = {p(2) ∈ P3 | p'(-3) < 0}

To check if W1 is a subspace, we need to verify if it satisfies the three conditions.

1. Closure under addition: Let p1(2) and p2(2) be two polynomials in W1. We need to show that p1(2) + p2(2) is also in W1. However, closure under addition is not guaranteed because the sum of two polynomials may not have a derivative at -3, making it difficult to determine if p'(-3) < 0. Therefore, W1 is not closed under addition and is not a subspace.

(ii) W2 = {A ∈ R2x2 | det(A) = 0}

To check if W2 is a subspace, we need to verify if it satisfies the three conditions.

1. Closure under addition: Let A1 and A2 be two matrices in W2. We need to show that A1 + A2 is also in W2. For the sum of two matrices, the determinant of their sum is not necessarily zero. Therefore, W2 is not closed under addition and is not a subspace.

(iii) W3 = {X = (L1, L2, L3, x4) ∈ R4 | X1 – 2x2 + 3x3 – 4x4 = 0}

To check if W3 is a subspace, we need to verify if it satisfies the three conditions.

1. Closure under addition: Let X1 and X2 be two vectors in W3. We need to show that X1 + X2 is also in W3. By adding the corresponding entries, we can see that the sum of the vectors will still satisfy the equation X1 – 2x2 + 3x3 – 4x4 = 0. Therefore, W3 is closed under addition.

2. Closure under scalar multiplication: Let X be a vector in W3 and c be a scalar. We need to show that cX is also in W3. By multiplying each entry of X by c, the equation X1 – 2x2 + 3x3 – 4x4 = 0 is still satisfied. Therefore, W3 is closed under scalar multiplication.

3. Contains the zero vector: The zero vector (0, 0, 0, 0) satisfies the equation X1 – 2x2 + 3x3 – 4x4 = 0. Therefore, W3 contains the zero vector. Since W3 satisfies all three conditions for being a subspace, we can conclude that W3 is a subspace.

You can rent time on computers at the local copy center for 35 minutes with $25.

To find out how much time you can rent for $25 at the local copy center, follow these steps:

1. Subtract the $10 setup charge from the total amount you have: $25 - $10 = $15.
2. Now you have $15 left for renting time on the computers. Since it costs $2 for every 5 minutes, you need to find out how many 5-minute increments can be covered by $15.
3. Divide the remaining amount by the cost per 5-minute increment: $15 / $2 = 7.5. Since you can't have half an increment, round down to 7.
4. Multiply the number of 5-minute increments by the time per increment: 7 * 5 = 35 minutes.

So, you can rent time on computers at the local copy center for 35 minutes with $25.
