What value of x cannot be evaluated in the function r(x)?​

Answer:

x = 17, x = 112, x = 100

Step-by-step explanation:

First problem:

From what I can see, there is a 90º angle present. When you subtract 73 from 90, you get 17, so x is 17.

Second problem:

x and 112 are vertical angles. "Vertical angle theorem, no matter how you throw your skewers or pencils so that they cross, or how two intersecting lines cross, vertical angles will always be congruent, or equal to each other." - https://tutors.com/math-tutors/geometry-help/vertical-angles

Third problem:

The base is a straight, horizontal line, which means that it is 180º. Subtract 80 from 180, you get 100. Therefore, x is 100.

Answer:

(x - 10)² + (y + 4)² = 121

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (10, - 4 ) and r = 11 , then

(x - 10)² + (y - (- 4) )² = 11² , that is

(x - 10)² + (y + 4)² = 121

Step-by-step explanation:

The students should use a t-test to analyze the significance of the data they collected is a true statement.

In this scenario, the population standard deviation is unknown and the sample size is small (n=25). Therefore, a t-test should be used instead of a z-test. The t-test is a statistical hypothesis test that is used to determine if there is a significant difference between the means of two groups when the sample size is small and/or the population standard deviation is unknown.

Using a t-test will allow the students to analyze the significance of their data in a more appropriate and accurate way, taking into account the small sample size and the fact that they do not know the population standard deviation.

Step-by-step explanation:

(7x-30) is the expression which you can use that is equivalent to 5x -2(15-x).

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Given: \(5x-2(15-x)\)

On solving the above equation we get ,

⇒ 5x - 2 (15) + 2 (x)

⇒ 5x - 30 + 2x

⇒ (5x + 2x) - 30

⇒(7x - 30)

Hence, we can say that (7x-30) is the expression which we can use and that is equivalent to 5x -2(15-x).

By using the power rule of integration, the solution for F(x) is: F(x) = \(4x^4 + 7x^2 + 7x - 23\)

To find F, we need to integrate F'(x) with respect to x.
So, F(x) = ∫(16x³ + 14x + 7) dx
Using the power rule of integration, we can integrate each term separately.
∫(16x³) dx = \(4x^4\) + C1
∫(14x) dx = 7x² + C2
∫(7) dx = 7x + C3
Adding all of these results, we get:
F(x) = \(4x^4\) + 7x² + 7x + C
Now, we need to use the initial condition F(1) = -5 to solve for the constant C.
F(1) = \(4(1)^4\) + 7(1)² + 7(1) + C = -5
Simplifying this equation, we get:
4 + 7 + 7 + C = -5
C = -23
Therefore, the solution for F(x) is: F(x) = \(4x^4 + 7x^2 + 7x - 23\)

Answer:

two hours after the snow started melting, the depth of the snow would be 8 inches.

Step-by-step explanation:

The melting can be represented by a linear function of the snow depth (D(t)) as a function of time (t). We consider that the initial value is: 11 inches deep at time = 0 (zero). and then decreasing at a rate of 1.5 inches per hour (that is a negative slope = -1.5).

\(D(t)=11-1.5\,t\)

Therefore, 2 hours after the snow started melting, one would have:

\(D(2)=11-1.5\,(2)=11-3=8\,\,inches\)

The domain of the inequality is from zero to negative infinity

The domain refers to the values in the input of a function, these values are in the x direction.

The slope-intercept form of line that passes through the point (-2,8) and has a slope of 5/2 is

\(y=\frac{5}{2}x + 13\)

Step-by-step explanation:

Equation of line in point-slope form is

\(y-y_1=m(x-x_1)\) ---------- (1)

Here

\(m=\frac{5}{2} \ \ \ and \ \ \ (x_1, y_1) = (-2, 8)\)

Substituting values in equation (1)

\(y-8=\frac{5}{2} (x + 2)\)

Simplifying it further

\(y=\frac{5}{2}x + \frac{5}{2}2 +8\)

\(y=\frac{5}{2}x + 5 +8\)

Answer:

C = 112, A = 150, D = 30, B = 38

Step-by-step explanation:

I solved C first using:

30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)

-

I solved A by looking across from C.

Angles on opposite sides should mirror each other but A includes 38* + C

Just by doing 112 + 38 you get 150.

-

I solved D by looking at 30*, alternative interior angles are the same so D is 30*.

-

I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.

Interior angles of a triangle should all add up to 180,

112 + 30 + B = 180

From this I got that B was 38.

Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.

I suggest reviewing this angles sheet if you're ever stuck in the future.

The accepting state will be state 0 since it represents even numbers in base-3. The NFA can transition to both states at the beginning, but it only needs to be in the accepting state at the end to accept an even number.

a) DFA for {strings in which the number of even digits is odd}:

The DFA will have two states: an even state and an odd state. The initial state will be the even state. When the DFA reads an odd digit (1 or 3), it will transition to the other state. When it reads an even digit (0 or 2), it will stay in the same state. The accepting state will be the odd state. This DFA will accept strings in which the number of even digits is odd.

b) DFA for {strings, when interpreted as a base-3 number, are even numbers}:

The DFA will have three states: state 0, state 1, and state 2. The initial state will be state 0. When the DFA reads a digit, it will transition to the state corresponding to that digit. For example, if it reads a 0, it will transition to state 0; if it reads a 1, it will transition to state 1, and if it reads a 2, it will transition to state 2. The accepting state will be state 0 since it represents even numbers in base-3.

c) DFA for {strings, when interpreted as a base-3 number, are even numbers having an odd number of even digits}:

This DFA will have three states: state 0, state 1, and state 2. The initial state will be state 0. When the DFA reads a digit, it will transition to the state corresponding to that digit. Similar to the previous DFA, the accepting state will be state 0. However, we need to keep track of the number of even digits. To achieve this, we can introduce a counter. Every time the DFA transitions to state 2, representing an even digit, the counter will be incremented. If the counter becomes odd, the DFA will transition to state 1. In state 1, it will accept only odd numbers of even digits.

d) DFA for {strings, when interpreted as a base-3 number, are not an even number}:

This DFA will have three states: state 0, state 1, and state 2. The initial state will be state 0. When the DFA reads a digit, it will transition to the state corresponding to that digit. The accepting state will be state 1 and state 2 since these states represent odd numbers in base-3.

e) NFA for {strings, when interpreted as a base-3 number, is an even number}:

The NFA will have two states: state 0 and state 1. The initial state will be state 0. When the NFA reads an odd digit (1 or 2), it will transition to both state 0 and state 1. When it reads an even digit (0), it will stay in the same state. The accepting state will be state 0 since it represents even numbers in base-3. The NFA can transition to both states at the beginning, but it only needs to be in the accepting state at the end to accept an even number.

The dimensions of the cylinder with the greatest volume that can be inscribed in the sphere are a height of 12 feet and a radius of 6 feet, and its maximum volume is approximately 1,152π cubic feet.

To find the dimensions of the cylinder with the greatest volume that can be inscribed in the given sphere, we need to consider the diameter of the sphere, which is twice the radius (12 feet). This diameter will be the height of the cylinder.

The maximum volume of the cylinder can be found by using the formula for the volume of a cylinder: V = πr^2h, where r is the radius of the cylinder and h is its height. Since the cylinder is inscribed in the sphere, its radius will be half of the diameter of the sphere, which is 6 feet. Therefore, we have:

V = π(6 feet)^2(12 feet) = 1,152π cubic feet

Answer:

y= 25x

Step-by-step explanation:

Answer:

The line can be defined as y = 25x.

Step-by-step explanation:

First we find two points that this falls on.  (0, 0) and (200, 8) clearly visible points that it falls on.  If we take common factors out of that, we get (1, 25).

With those points, we have the slope of the function.  Slope is equal to Δy/Δx, so in this case its 25/1 or just 25

Normally, to define a line, we would take a point on it and use it as reference, defining the line as (y - y1) = s(x - x1).  In this case though, because the line intersects point (0, 0), we don't even need to translate it.  We can simply say:

y = sx

We already have our slope of 25, so the our line function is:

y = 25x
