Answer:

Domain is {x| 1<=x <5}

Step-by-step explanation:

The graph of the piecewise function f(x) is shown.

In the given graph of piecewise function

Domain is the set of x values for which the function is defined

first graph is from x= 1 to 3, 3 is excluded

second graph is from x= 3 to 5, 5 is excluded

So the graph of x values is from x=1 to 5 ( 5 excluded because we have open circle at 5)

Domain is {x| 1<=x <5}

Answer:

it is the distance of a circle

Answer:

[tex]p(x)=-0.0005x+29[/tex]

Step-by-step explanation:

It is given that a baseball team plays in a stadium that holds 51,000 spectators.

Let x be the attendance and p be the price.

With ticket prices at $10, the average attendance had been 38,000. When ticket prices were lowered to $8, the average attendance rose to 42,000.  

Assuming that the demand function is linear. It means, the demand line passes through the points (38000,10) and (42000,8).

The equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-10=\dfrac{8-10}{42000-38000}(x-38000)[/tex]

[tex]y-10=\dfrac{-2}{4000}(x-38000)[/tex]

[tex]y-10=-0.0005(x-38000)[/tex]

[tex]y-10=-0.0005x-0.0005(-38000)[/tex]

[tex]y-10=-0.0005x+19[/tex]

[tex]y=-0.0005x+19+10[/tex]

[tex]y=-0.0005x+29[/tex]

Substitute y=p(x).

[tex]p(x)=-0.0005x+29[/tex]

Therefore, the demand function is [tex]p(x)=-0.0005x+29[/tex].

Explanation of how to expand and simplify the given quadratic expression Hence answer is 4a²x² + abx² + 1/4b²x²,

Solve the equation: (2ax + 1/2 bx)²

Expanding the given expression:

(2ax + 1/2 bx)²

= (2ax)² + (2ax) (1/2 bx) + (1/2 bx)²

= 4a²x² + 2abx² + 1/4b²x²

= 4a²x² + abx² + 1/4b²x²

Answer: 4a²x² + abx² + 1/4b²x²

The equation of a line with an undefined slope passing through the point (2, 5) can be written as x = 2.

When the slope of a line is undefined, it means that the line is vertical. In a vertical line, the x-coordinate remains constant while the y-coordinate can take any value.

So, for this line passing through the point (2, 5), the x-coordinate will always be 2, regardless of the value of y. Therefore, we can represent this line with the equation x = 2.

A function is denoted as y = f (x), where x is the argument or input of the function. This means that from  f(6) follows that x= 6, and to get the answer we should replace x with 6.

f(6)=6^2÷ 3 + 6= 36÷ 3 + 6= 12+6= 18

f(6)=18

Answer:

The value of f(6) is, 18

Step-by-step explanation:

Given the function:

[tex]f(x) = x^2 \div 3+ x[/tex]               .....[1]

We have to find the value of [tex]f(6)[/tex].

Put x = 6 in [1] we have;

[tex]f(6) = 6^2 \div 3+ 6[/tex]

⇒[tex]f(6) = 36 \div 3 +6[/tex]

⇒[tex]f(6) = \frac{36}{3}+6[/tex]

Simplify:

[tex]f(6) = 12 +6 = 18[/tex]

Therefore, the value of f(6) is, 18

The volume of the ball bearing, which is a sphere, would be approximately 8.18 cm³. This is calculated using the formula for the volume of a sphere and the given diameter, which is halved to get the radius for the calculation

The volume of a sphere can be calculated using the formula V = 4/3 * π * r³, where r is the radius of the sphere. In this case, the diameter of the ball bearing is 2.5 cm, so the radius would be half of that (diameter/2), which is 1.25 cm. Substituting the radius value to the volume formula, we get: V = 4/3 * π * (1.25cm)³ = 4/3 * 3.14 * 1.95cm³ = approximately 8.18 cm³, rounded to the nearest hundredth.

Final answer:

For the function f(x) = (sinx)/x to be continuous at x = 0, the value of k must be 1, which is the limit of the function as x approaches 0.

Explanation:

The student is asking about the continuity of a given function at x = 0. To determine what the value of k must be for the function f(x) = (sinx)/x when x is approaching 0, we need to look at the limit of the function as x approaches 0.

Although the function is not defined at x = 0 due to division by zero, we know that the limit of (sin x)/x as x approaches 0 is 1. This can be proven using L'Hospital's rule or the squeezing theorem. Hence, for the function to be continuous at x = 0, the value of k must also be 1.

By the principle of mathematical induction, we have shown that for all positive integers n, n^3 + 2n is divisible by 3.

Proof by Induction: n^3 + 2n is divisible by 3 for all positive integers n.

Base Case:

For n = 1, n^3 + 2n = 1^3 + 2(1) = 3, which is divisible by 3.

Induction Hypothesis:

Assume that for some positive integer k, k^3 + 2k is divisible by 3. We can write this as: k^3 + 2k = 3m, where m is an integer.

Induction Step:

We need to show that (k + 1)^3 + 2(k + 1) is divisible by 3. Expanding the expression:

(k + 1)^3 + 2(k + 1) = k^3 + 3k^2 + 3k + 1 + 2k + 2

= (k^3 + 2k) + (3k^2 + 3k + 3)

Substituting the induction hypothesis:

= 3m + 3(k^2 + k + 1)

= 3(m + k^2 + k + 1)

Since k^2 + k + 1 is an integer (sum of three integers), and m is an integer, their sum (m + k^2 + k + 1) is also an integer. Therefore, (k + 1)^3 + 2(k + 1) is divisible by 3.

To find the sprinter's unit rate of feet per second, divide the total distance by the time. In this case, the sprinter's unit rate is approximately 31 feet per second.

To find the sprinter's unit rate of feet per second, we need to divide the total distance the sprinter can run by the time it takes. In this case, the sprinter can run 279 feet in 9 seconds. So the unit rate is 279 feet divided by 9 seconds, which is approximately 31 feet per second.

Answer : The north middle school have fewer than 750 students.

Step-by-step explanation:

Let the number of students in south middle school be, x

and the number of students in north middle school be, y

Given:

Number students in south middle school = x = 750

and,

North middle school has 13/15 times as many students as South. That means,

[tex]y=\frac{13}{15}\times x[/tex]   ........(1)

Now put the value of 'x' in expression 1, we get:

[tex]y=\frac{13}{15}\times 750[/tex]

[tex]y=650[/tex]

Thus, number of students in north middle school = y = 650

From this we conclude that north middle school have fewer than 750 students.

Hence, the north middle school have fewer than 750 students.
