True. A piece-wise function is composed of different functions that are joined together at certain points and each of these functions will either have an x-intercept or a y-intercept.

Yes, a piece-wise function will always have at least one x-intercept or at least one y-intercept. A piece-wise function is composed of different functions that are joined together at certain points. Each of these individual functions can either be linear, quadratic, or any other type of function, and each of these functions will either have an x-intercept or a y-intercept. For example, if a piece-wise function contains two linear equations, each of them will have one x-intercept and one y-intercept. The same is true for quadratic equations, and for any other type of equation. Therefore, since a piece-wise function is composed of these individual functions, it will always have at least one x-intercept or at least one y-intercept.

Step-by-step explanation:

We will get that the angle theta is:

θ = β/2

Remember that the sum of the interior angles of any triangle must be equal to 180°.

Now, looking at the triangle in the left, we can see that the top angle is equal to:

180 - 2α

The right angle is equal to:

180 - 2β

And the left angle is α

Then we can write:

α + (180 - 2α) + (180 - 2β) = 180

-α - 2β = -180

α = 180 - 2β

Now we can go to the other triangle, where theta is, and write:

α + β + 2θ = 180

Replacing what we found above, we get:

180 - 2β + β + 2θ = 180

-β + 2θ = 0

θ = β/2

That is the best simplification we can get with the given diagram.

The simplification by combining like terms  of 3a + b + a is 4a + b.

According to the given question.

We have an expression 3a + b + a.

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression  3a + b + a.

Answer:

The disk is using the MBR partitioning scheme.

Step-by-step explanation:

Master Boot Record (MBR) disks use the standard BIOS partition table

The MBR (master boot record) partitioning scheme is a partitioning scheme that limits the number of logical sectors to 32 bits. Therefore the maximum number that can be represented by 32 bits is 2³² (4,294,967,295), which is approximately 2 TB of capacity. Hence MBR partitioning scheme has a limit of 2 TB

For 1st year percentage increase is 100%

For 2nd Year percentage increase is 50%

In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 of 100 questions correctly on a test (75/100).

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.

Population function is

P(x) = 40000 * 1.2x

Population in 2015 , x = 1

P(1) = 40000*1.2 = 48000

Population in 2016 , x = 2

P(2) = 40000*1.2*2 = 96000

Population in 2017 , x = 3

P(3) = 40000*1.2*3 = 144000

So for 1st year percentage increase = (96000-48000)/48000 *100 = 100%

For 2nd Year percentage increase = (144000-96000)/96000 *100 = 50%

Answer:

\(y = {x}^{2} + 2\\y={x}^{3}+3\)

are the examples of non-linear equation.

The solution to the system of equations is x = 11.5 and y = -27.5.

The solution to the system of equations is x = 2 and y = 1

The solution to the system of equations is x = -12 and y = 7.

The solution to the system of equations is x = 0.5 and y = -6.

A system of linear equations can be solved graphically, by substitution, by elimination, and by the use of matrices.

To solve the system of equations:

3x + y = 7

5x + 3y = -25

We can use the method of substitution or elimination to find the values of x and y.

Let's solve it using the method of substitution:

From the first equation, we can express y in terms of x:

y = 7 - 3x

Substitute this expression for y into the second equation:

5x + 3(7 - 3x) = -25

Simplify and solve for x:

5x + 21 - 9x = -25

-4x + 21 = -25

-4x = -25 - 21

-4x = -46

x = -46 / -4

x = 11.5

Substitute the value of x back into the first equation to find y:

3(11.5) + y = 7

34.5 + y = 7

y = 7 - 34.5

y = -27.5

Therefore, the solution to the system of equations is x = 11.5 and y = -27.5.

To solve the system of equations:

2x + y = 5

3x - 3y = 3

Again, we can use the method of substitution or elimination.

Let's solve it using the method of elimination:

Multiply the first equation by 3 and the second equation by 2 to eliminate the y term:

6x + 3y = 15

6x - 6y = 6

Subtract the second equation from the first equation:

(6x + 3y) - (6x - 6y) = 15 - 6

6x + 3y - 6x + 6y = 9

9y = 9

y = 1

Substitute the value of y back into the first equation to find x:

2x + 1 = 5

2x = 5 - 1

2x = 4

x = 2

Therefore, the solution to the system of equations is x = 2 and y = 1.

To solve the system of equations:

2x + 3y = -3

x + 2y = 2

We can again use the method of substitution or elimination.

Let's solve it using the method of substitution:

From the second equation, we can express x in terms of y:

x = 2 - 2y

Substitute this expression for x into the first equation:

2(2 - 2y) + 3y = -3

Simplify and solve for y:

4 - 4y + 3y = -3

-y = -3 - 4

-y = -7

y = 7

Substitute the value of y back into the second equation to find x:

x + 2(7) = 2

x + 14 = 2

x = 2 - 14

x = -12

Therefore, the solution to the system of equations is x = -12 and y = 7.

To solve the system of equations:

2x - y = 7

6x - 3y = 14

Again, we can use the method of substitution or elimination.

Let's solve it using the method of elimination:

Multiply the first equation by 3 to eliminate the y term:

6x - 3y = 21

Subtract the second equation from the first equation:

(6x - 3y) - (6x - 3y) = 21 - 14

0 = 7

The resulting equation is 0 = 7, which is not possible.

Therefore, there is no solution to the system of equations. The two equations are inconsistent and do not intersect.

To solve the system of equations:

4x - y = 6

2x - y/2 = 4

We can use the method of substitution or elimination.

Let's solve it using the method of substitution:

From the second equation, we can express y in terms of x:

y = 8x - 8

Substitute this expression for y into the first equation:

4x - (8x - 8) = 6

Simplify and solve for x:

4x - 8x + 8 = 6

-4x + 8 = 6

-4x = 6 - 8

-4x = -2

x = -2 / -4

x = 0.5

Substitute the value of x back into the second equation to find y:

2(0.5) - y/2 = 4

1 - y/2 = 4

-y/2 = 4 - 1

-y/2 = 3

-y = 6

y = -6

Therefore, the solution to the system of equations is x = 0.5 and y = -6.

The recursive formula for the altitude of the plane with the given pattern after t minutes is equal to A(t)=30000 - 550(t−1).

As given in the question,

When time t = 1

Altitude of the plane is 30,000feet

t = 2 , altitude of the plane = 29,450 feet

t = 3 , altitude of the plane = 28,900 feet

Let A(t) be the altitude of the plane after time 't' minutes

Here , A(1) = 30,000

A(2) - A(1) = A(3) - A(2)

So, it is arithmetic progression series

Common difference 'd' = A(2) - A(1)

                                  = 29,450 - 30,000

                                  = -550

Recursive formula of the altitude of the plane represented by  't' th term of arithmetic progression series

A(t) = A(1) + ( t - 1 ) d

⇒ A(t) = 30,000 + ( t - 1 )(-550)

⇒A(t) = 30,000 - 550( t - 1 )

Therefore, the recursive formula of the altitude of the given plane after 't' minutes is equal to A(t) = 30,000 - 550( t - 1 ).

The probability that exactly 20 random numbers will fall in the interval 0.1 to 0.35 is approximately 0.0223, or 2.23%.

To solve this problem, we need to use the binomial probability formula:
\(P(X = k) = (n choose k)  p^k  ( (1 - p)^{n-k}\)

where:
- X is the random variable representing the number of successes (random numbers in the interval 0.1 to 0.35)
- k is the number of successes we want (exactly 20)
- n is the total number of trials (100)
- p is the probability of success (the probability that a randomly generated number falls in the interval 0.1 to 0.35)

To find p, we need to determine the fraction of the interval 0 to 1 that is between 0.1 and 0.35:
\(p = (0.35 - 0.1) / 1 = 0.25\\p = \frac{0.35-0.1}{1} = 0.25\)

Now we can plug in the values and calculate the probability:

\(P(X = 20) = (100 choose 20) (0.25)^{20}   (1-0.25)^{100-20}\)
= 0.0223

Therefore, the probability that exactly 20 random numbers will fall in the interval 0.1 to 0.35 is approximately 0.0223, or 2.23%.

The Bisection method converges to the zero at x = 0 for intervals a and b, the zero at x = 1 for interval c, and the zero at x = -1 for interval d.

The Bisection method is a numerical method for finding the roots of a function. It works by repeatedly dividing an interval in half and checking if the function changes sign in either half. If it does, then the root must be in that half and the process is repeated until the root is found to a desired level of accuracy.

To determine which zero of f the Bisection method converges to on the given intervals, we need to apply the method and see which zero is found.

a. [−1.5, 2.5]: The Bisection method will converge to the zero at x = 0, since f changes sign in the interval [−1.5, 0.5] and the method will continue to narrow in on this interval.

b. [−0.5, 2.4]: The Bisection method will also converge to the zero at x = 0, since f changes sign in the interval [−0.5, 0.5] and the method will continue to narrow in on this interval.

c. [−0.5, 3]: The Bisection method will converge to the zero at x = 1, since f changes sign in the interval [0.5, 1.5] and the method will continue to narrow in on this interval.

d. [−3,−0.5]: The Bisection method will converge to the zero at x = -1, since f changes sign in the interval [−1.5, -0.5] and the method will continue to narrow in on this interval.

The final temperature given the increase in temperature and the decrease in temperature is 18 degrees.

In order to determine if your friend has enough money to buy all the items, the total cost of the items have to be determined. The total cost is the sum of all the items bought.

here, we have,

Total cost = total cost of the first three items + total cost of the second three + total cost of the last three

Total cost = (3 x 15.99) + (3 x 10.40) + (4 x 4.50)

Total cost = $47.97 + $31.20 +18

Total cost = $97.17

An increase in temperature would be represented with a positive number. While, a decrease in temperature would be represented with a negative number. The final temperature can be determined by adding the temperature increase and decease together.

The difference in the rate of change between Function A and function B is -2.

The difference in the rate of change between function A and function B, we first need to identify the rate of change for each function. The rate of change, also known as the slope, represents how much the dependent variable (y) changes for every unit increase in the independent variable (x).

Let's assume function A is represented by the equation y = 2x + 3, and function B is represented by the equation y = 4x - 1.

For function A: y = 2x + 3, the coefficient of x is 2, indicating that for every unit increase in x, y increases by 2. Therefore, the rate of change for function A is 2.

For function B: y = 4x - 1, the coefficient of x is 4, indicating that for every unit increase in x, y increases by 4. Therefore, the rate of change for function B is 4.

Now, to find the difference in the rate of change between function A and function B, we subtract the rate of change of function B from the rate of change of function A:

Difference in rate of change = Rate of change of function A - Rate of change of function B

                          = 2 - 4

                          = -2

The difference in the rate of change between function A and function B is -2. This means that for every unit increase in x, function B increases at a rate that is 2 units greater than function A. It indicates that function B has a steeper slope and a faster rate of change compared to function A.

In summary, the difference in the rate of change between function A and function B is -2.
