Step-by-step explanation:

Using law of cosine and Pythagorean theorem, the length of BC is 18 foot and CD is 12.3 foot

a) To find the length of support member BC, we can use the Law of Cosines:

BC^2 = AC^2 + AB^2 - 2 * AC * AB * cos(m/C)

where m/C is the measure of angle C. We know that m/A = 40° and m/D = 45°, so m/C must be the supplementary angle to the sum of these angles:

m/C = 180° - (m/A + m/D) = 180° - (40° + 45°) = 95°

Substituting known values into the Law of Cosines equation, we have:

BC^2 = 10^2 + 8^2 - 2 * 10 * 8 * cos(95°)

BC^2 = 100 + 64 + 160

BC^2 = 324

BC = sqrt(324) = 18

So, the length of support member BC is 18 feet to the nearest hundredth of a foot.

b) To find the length of cable CD, we can use the Pythagorean Theorem:

CD^2 = BC^2 + AC^2 - 2 * BC * AC * cos(m/A)

Substituting known values into the equation, we have:

CD^2 = 18^2 + 10^2 - 2 * 18 * 10 * cos(40°)

CD^2 = 324 + 100 - 360 * cos(40°)

CD^2 = 424 - 360 * cos(40°)

Using the cosine formula, we can find the value of cos(40°):

cos(40°) = cos(90° - 40°) = sin(40°)

And using a reference table or calculator, we find that sin(40°) = 0.766

So, substituting the value of cos(40°) back into the equation for CD^2, we have:

CD^2 = 424 - 360 * 0.766

CD^2 = 424 - 276.56

CD^2 = 147.44

CD = sqrt(147.44) = 12.3

So, the length of cable CD is 12.3 feet to the nearest hundredth of a foot.

The values of v for the electric impulse model in the Fitzhugh-Nagumo model are 0, 1, and a.

The strength of the field is shown by the distance between the lines; the closer they are to one another, the stronger the field.

In this scenario, the field weakens as we travel away from the charge because the distance between the lines widens (it actually obeys an inverse square law,

The electric field, which is pointed away from the core charge, is indicated by the direction of the lines.

This is due to the fact that a positive test charge would be repelled away from the electric field if it were placed there because the direction of the electric field corresponds to the direction of the force that a positive test charge would experience when immersed in the electric field.

Hence, The values of v for the electric impulse model in the Fitzhugh-Nagumo model are 0, 1, and a.

x = 7

Step-by-step explanation:

Based on the angle bisector theorem, we would have the following equation:

21/(3x - 12) = 14/6

21/(3x - 12) = 7/3

Cross multiply

(3x - 12)*7 = 3*21

21x - 84 = 63

21x - 84 + 84 = 63 + 84

21x = 147

Answer:

B OR D

Step-by-step explanation:

The values of x that make the expression undefined are 0 and 2

From the question, we have the following parameters that can be used in our computation:

Volume = 5 - x

Width = x - 2

Height = 5 - x/x(x -2)

Introduce brackets to the height expression to differentiate between the numerator and the denominator

So, we have

Height = (5 - x)/x(x -2)

The question implies that we calculate the domain

Set the denominator to 0

This gives

x(x - 2) = 0

So, we have

x = 0 or x - 2 = 0

Solve for x

x = 0 or x = 2

This means that the undefined height value of x are 0 and 2

Answer:

Hello,

45.8%

Step-by-step explanation:

67.7% x 67.7% = 0.677 x 0.677 = 0.677² = 0.458329 ≈ 45.8%

Keep in mind that without the population standard deviation, it is impossible to provide an exact sample size. However, this formula will give you a good starting point.

To find the sample size needed for a 99.5% confidence interval with a margin of error of 1.5, we can use the formula:

n = (Z * σ / E)^2

where n is the sample size, Z is the Z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the margin of error.

For a 99.5% confidence interval, the Z-score is approximately 2.807 (from a standard normal distribution table). Since we do not have the population standard deviation (σ), we will need to estimate it using a sample standard deviation or use a conservative approach by assuming the maximum possible value. For now, let's assume we have an estimated standard deviation.

n = (2.807 * σ / 1.5)^2

Solve for n by plugging in the estimated standard deviation (σ) and then round up to the nearest whole number, as you cannot have a fraction of a sample.

Answer:

The best buy is the 16-ounce drink

Step-by-step explanation:

here, we see that,

12 ounce = 3/4 (16 ounce)

So, the price should reflect that,

i.e,

price of 12 ounce drink = 3/4 (price of 16 ounce drink)

By this metric,

Price of 12 ounce drink = 3/4 ( 1.19)

Price of 12 ounce drink = $0.8925

So, 12-ounce drink should cost $0.8925 but the actual drink costs $0.99,

So, it is more expensive than it should be,

So, the best buy is the 16-ounce drink

The equation of the line is y = x/7 - 1/7

The equation of a straight line is y=mx+c . Where m is the gradient or slope and c is the height at which the line crosses the y -axis, also known as the y -intercept.

The equation of a line can be expressed as;

y-y1 = m(x -x1)

where m is the slope

The slope = 1/7

x1 = 8 and y1 = 1

Therefore;

y -1 = 1/7( x -8)

7(y-1) = x-8

7y -7 = x-8

collecting like terms

7y = x - 8+7

7y = x -1

y = x/7 -1/7

The intercept is -1/7 and the slope is 1/7

Answer:

Step-by-step explanation:

Step 1:  First, we must plug in 7 for x in f(x) and g(x):

f(7) = 2(7) + 1

f(7) = 14 + 1

f(7) = 15

g(7) = 7-2

g(7) = 5

Now, we can divide f(7) by g(7)

f(7) / g(7) = 15 / 5

f(7) / g(7) = 3

Thus, the quantity of f divided by g of 7 is 3

Therefore, the answer is A. {5, 5√3, 10}.

The set of values {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

In a 30-60-90 triangle, the sides are in a specific ratio. The ratio is 1 : √3 : 2, where the shortest side (opposite the 30-degree angle) has length x, the side opposite the 60-degree angle has length x√3, and the hypotenuse (opposite the 90-degree angle) has length 2x.

Let's check if the given set of values satisfies this ratio:

   If x= 5, then the side opposite the 60-degree angle should be 5√3, and the hypotenuse should be 10. These values match the ratio, so the set {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

The given function is,

The range is the set of all output values of the function.

Since the square of a number cannot be less than zero, the range of the function f(x) is [0, ∞).

The length of the field is greater than the width by the expression \((14x - 3x^2 + 2y) - (5x - 7x^2 + 7y).\)

1. The length of the field is represented by the expression \(14x - 3x^2 + 2y.\)

2. The width of the field is represented by the expression \(5x - 7x^2 + 7y\).

3. To find the difference between the length and width, we subtract the width from the length: (\(14x - 3x^2 + 2y) - (5x - 7x^2 + 7y\)).

4. Simplifying the expression, we remove the parentheses: \(14x - 3x^2 + 2y - 5x + 7x^2 - 7y.\)

5. Combining like terms, we group the \(x^2\) terms together and the x terms together: \(-3x^2 + 7x^2 + 14x - 5x + 2y - 7y.\)

6. Simplifying further, we add the coefficients of like terms:\((7x^2 - 3x^2) + (14x - 5x) + (2y - 7y).\)

7. The simplified expression becomes: \(4x^2 + 9x - 5y.\)

8. Therefore, the length of the field is greater than the width by the expression \(4x^2 + 9x - 5y.\)
