Final answer:

Maria can convert 500 centimeters to meters by dividing by 100. So, she would end up with 5 meters since each meter contains 100 centimeters.

Explanation:

Maria wants to convert 500 centimeters to meters to determine how many meters she has. Conversion between centimeters and meters is a common mathematical process. Since there are 100 centimeters in a meter, Maria needs to divide the number of centimeters by 100 to get the measurement in meters. So, she would calculate 500 cm ÷ 100, which equals 5 meters.

To visualize this, imagine you have a ruler that measures in centimeters. If you laid out rulers end to end until you reached 500 centimeters, you would have the equivalent length of 5 meters because every 100 centimeters make up 1 meter.

Example:

If we had 200 cm, we would divide by 100 and find that 200 cm equals 2 m. Comparing this to a meter stick, which measures 1 meter, we can see that 200 cm is greater than 1 m and would require using the meter stick twice to measure the entire length.

The tangent line to the curve at (0, 2) is y = 2x + 2, and the normal line is y = -1/2x + 2.

To find the equations of the tangent line and normal line to the curve at the given point (0, 2) for the function y = [tex]x^{4} +2e^{x}[/tex], we first need to determine the derivative of the function at that point.

1. Differentiate the function y =[tex]x^{4} +2e^{x}[/tex] with respect to x:

dy/dx = [tex]4x^{3} +2e^{x}[/tex]

2. Evaluate the derivative at the given point (0, 2):

dy/dx |(0, 2) = [tex]4(0)^{3}[/tex] + 2[tex]e^{0}[/tex] = 2

3. The slope of the tangent line at the point (0, 2) is 2.

4. Use the point-slope form to find the equation of the tangent line:

y - 2 = 2(x - 0)

y = 2x + 2

5. The slope of the normal line is the negative reciprocal of 2, which is -1/2.

6. Use the point-slope form to find the equation of the normal line:

y - 2 = (-1/2)(x - 0)

Simplify:

y = -1/2x + 2.

To compute for combinations, we will use the method nCr = n! / r! * (n - r)!

Where: n signifies the number of items, and r signifies the number of items being selected at a time.

Solution

1.       11C5 = 11!/ 5! * (11-5)! = 462 ways

2.       6C5 = 6!/ 5! * (6-5)! = 6 ways

3.       6/462 = 1/77 or 0.1230 is the probability that the selected group will consist of all men.

The calculation involves using combinations to find the total number of ways to select 5 people from 11, and then to find the probability of selecting 5 men by dividing the number of ways to select 5 men from 6 by the total number of selections.

The student's question deals with the topic of combinatorics, specifically the selection of groups and calculation of probabilities using the hypergeometric distribution. To find how many ways 5 people can be selected from a group of 11 (6 men and 5 women), we use the combination formula [tex]C(n, k) = n! / (k!(n-k)!).[/tex]

For the first part of the question, selecting 5 people out of 11, the calculation is C(11, 5). To calculate the number of ways 5 men can be selected from 6 men, we use C(6,5).

Lastly, to find the probability that the selected group will consist of all men, we divide the number of ways to select 5 men by the total number of ways to select 5 people from the whole group:

Final answer:

By calculating slopes of the triangle's sides and identifying that two of them are negative reciprocals of each other, it's confirmed that the triangle with vertices (-4, 4), (1, 5), and (2, 0) is a right triangle.

Explanation:

To determine if the triangle with vertices (-4, 4), (1, 5), and (2, 0) is a right triangle, we calculate the slopes of all three sides. The slope of the line between points (-4, 4) and (1, 5) is calculated using the slope formula m = (y2 - y1) / (x2 - x1). Using the coordinates, the slope is (5 - 4) / (1 - (-4)) = 1 / 5. Similarly, the slope between points (1, 5) and (2, 0) is (0 - 5) / (2 - 1) = -5. Lastly, the slope of the line between (-4, 4) and (2, 0) is (0 - 4) / (2 - (-4)) = -4 / 6, which simplifies to -2 / 3. A right triangle has one 90-degree angle, and the slopes of perpendicular lines are negative reciprocals of each other. Therefore, if two of these slopes are negative reciprocals, the triangle is a right triangle. In this case, the slopes -5 and 1/5 are negative reciprocals, confirming that the triangle is a right triangle.

The derivative of 3g(x) is 3g'(x), obtained by taking the derivative of the function and multiplying it by the constant.

Explanation:

Derivative of 3g(x):

Yes, the derivative of 3g(x) is indeed **3g'(x)**.

When you have a constant multiplied by a function, you can simply take the derivative of the function and multiply it by the constant to find the derivative of the entire expression. In this case, the derivative of 3g(x) would be 3 times the derivative of g(x), which is 3g'(x).

The expression  4(3x-2)-2(4x+5) in it's simplest binomial form is 4x - 18.

We can classify algebraic expressions in terms of how many terms they have. If an algebraic expression has only one term we call it a monomial, having two terms makes it a binomial and having more than two terms makes it a polynomial

We know a binomial consists of two terms separated by any of the arithmetic operations.

Step-by-step explanation:

The given expression is :

[tex]\frac{-3x^{3}+5x+14}{x-2}[/tex]

Factoring [tex]-3x^{3}+5x+14[/tex]

Factor out common term -1

[tex]3x^{3}-5x-14[/tex]

Now dividing leading coefficients of numerator and divisor.

We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.

We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m

Depth of titanic = 3,797 m (1 km / 1000 m)

Depth of titanic = 3.797 km = 3.8 km

To find the zeros of the function f(x) = 4x2 – x – 5, we first set the equation to zero, factor it to find (4x - 5)(x + 1) = ​0, and solve for x, finding the zeros to be 5/4 and -1.

The first step in factoring the quadratic function f(x) = 4x2 – x – 5 is to set the equation to zero.

The factored form of a quadratic equation is generally represented as (ax + b)(cx + d) = 0, where x is the zeros of the function. So, the equation we have is 4x² - x - 5 = 0.

Now, we need to look for two numbers that multiply to (a*c) = -20 (4*-5) and add up to -1 which are -5 and 4. Hence, the middle expression -x can be expressed as -5x + 4x, so the equation becomes:
4x² - 5x + 4x - 5 = 0.

Factoring, we get the following:
x(4x - 5) + 1(4x - 5) = 0.

Or we could write as:
(4x - 5)(x + 1) = ​0.

Now, to find zeros of the function, we set each factor equal to zero and solve for x:

4x - 5 = 0 implies, x = 5/4.

x + 1 = 0 implies, x = -1.

So, the zeros of the function are 5/4 and -1.

Final answer:

The measure of one interior angle of a regular convex 31-gon is approximately 168.39 degrees, calculated by dividing the sum of the interior angles, 5220 degrees, by the number of sides.

Explanation:

The measure of one interior angle of a regular convex 31-gon can be calculated using the formula for the sum of the interior angles of a polygon, which is (n - 2) × 180°, where n is the number of sides. For a 31-gon, the sum of the interior angles is,

(31 - 2) × 180°

= 29 × 180°

= 5220°.

To find the measure of one interior angle, you divide the total sum by the number of sides, so it is 5220° ÷ 31 ≈ 168.39°.

C.) Point B is between points A and C.

Step-by-step explanation:

The simplest way to analyze this is as a line.

This line goes from A to C and somewhere in the middle, is B.

But they tell you that AB + BC = AC.

The distance from A to B plus the distance from B to C is the same as the distance from A to C.

Option A about planes is not the correct one because there's no mention of planes.

Option B about angles is not correct because they only talk about some points of a line. You don't know if there's some angle in between.

The decay of a substance with a half-life can be modeled using the formula [tex]\(N(t) = N_0 \left(\frac{1}{2}\right)^{\frac{t}{T_{\text{half}}}}\)[/tex], where:

- [tex]\(N(t)\)[/tex] is the remaining quantity after time \(t\),

- [tex]\(N_0\)[/tex] is the initial quantity,

- [tex]\(T_{\text{half}}\)[/tex] is the half-life.

In this case, [tex]\(N(t) = \frac{1}{5}N_0\)[/tex] and [tex]\(T_{\text{half}} = 1590\)[/tex] years.
