The function breaks at (-2,0),(0,-2)&(4,0).So at all these points function i.e triangular curve takes the turn.

That is what kind of continuous function?

A continuous function in mathematics is one whose value does not abruptly change due to discontinuities, or breaches in the continuity of the function.

                                  For example, the function f (x) = 2 sin (x), f (x) = 2 sin (x), and f (x) = 2sin (x) is continuous everywhere. We can sketch its outline without ever lifting our hand. Contrarily, there is a discontinuity at x = 2 x = 2 x = 2 in the function f (x) = 1 x 2 f(x) = frac 1 x 2 f(x) = x 21.

The four points given are (-2,0),(0,-2),(2,-1),(4,0).When you will plot these points on the coordinate axes and join all these points you will get the shape of a triangle. One line lies completely on x axis another two lies below   x axis. These two  lines intersect at  (0,-2).

The meaning of continuity is that there should be no breaking points in the function.

But the function breaks at (-2,0),(0,-2)&(4,0).So at all these points function i.e triangular curve takes the turn.

So this might be also the turning point.

The possible turning point for the continuous function f(x) from the given list is likely the point (2, -1), where the second derivative y" = 6x - 12 equals zero, indicating a point of inflection.

To determine a possible turning point for the continuous function f(x), we need to consider the concept of a point of inflection, which is a point where the concavity of the function changes. According to the excerpts, a point of inflection occurs where the second derivative of the function changes sign or is zero. If we examine the given points, a turning point might be where we can see such a change in concavity or where the f'(x) equals zero.

From the excerpt that gives us the second derivative y" = 6x - 12, we can determine that at x = 2, the second derivative is zero, which signals a possible point of inflection. This would correspond to the point (2, -1) in the list provided. Hence, this is a possible turning point for the function f(x).

The expression with square roots simplifies to x squared times y to the 4.5th power, or x squared times y to the 4th power times the square root of y, applying the rules for multiplying exponents and expressing square roots as fractional powers.

To solve the expression involving square roots and variables raised to different powers, we apply the rules of exponents and radical expressions. The student asks about the square root of xy2 multiplied by the square root of x3y7. First, we express the square roots as fractional powers, and then we use the rule of multiplication of exponents.

For square roots, the rule is that the square root of x can be rewritten as x raised to the 1/2 power. As in the examples provided, the rule for raising a number to a power (xp) and then multiplying it by the same base raised to another power (xq) is to add the exponents, resulting in xp+q. Finally, the cube of an exponential involves cubing the digit term and multiplying the exponent by 3.

In this case:

When we multiply these together:

(x1/2y) * (x3/2y7/2) = x1/2+3/2y1+7/2 = x2y9/2

This expression simplifies to x2y4.5 or x2y4√y.

The simplified form of the given expression -|15| is -15.

Use the concept of modulus defined as:

A modulus function is a function that determines a number or variable's absolute value. It generates the size of the variable count.

A function with absolute values is another name for it. No matter what input was provided to this function, the output is always favorable.

The given expression is -|15|

Since we know that,

|x| = x when x > 0

|x|  = 0 when x = 0

|x| = -x when x<0

And here 15 > 0

Therefore,

|15| = 15

then -|15| = -15

Hence,

The simplified form of the given expression is -15.

Answer:

x = [tex]\frac{5P}{h}[/tex]

Step-by-step explanation:

Given

P = [tex]\frac{hx}{5}[/tex] ( multiply both sides by 5 )

5P = hx ( divide both sides by h )

x = [tex]\frac{5P}{h}[/tex]

The given equation P = hx/5 can be rearranged to x = 5P/h, by first multiplying both sides by 5, and then dividing both sides by h

The current equation P = hx/5 can be rearranged to isolate x by employing algebraic steps. We first need to get rid of the division by 5 from the right side of the equation to leave hx isolated. We achieve this by performing the opposite operation, that is multiplication on both sides of the equation by 5:

5P = 5*(hx/5)

This simplifies to 5P = hx.

Finally, to obtain x by itself, we want to get rid of the multiplication by h in the equation. We do so by dividing both sides of the equation by h:

(5P)/h = hx/h

Which simplifies to: x = 5P/h

This is the final rearranged equation with x isolated.

Step-by-step explanation:

Hope this helps!!! :)

The rate of change of the linear function in the graph is: 5

Rate of change problems can generally be approached using the formula R = D/T, or rate of change equals the distance traveled divided by the time it takes to do so.

However, in this case with coordinates, it is expressed as:

Rate of change = (y₂ - y₁)/(x₂ - x₁)

From the graph, we can take two coordinates which are:

(1, -1) and (2, 4).

Answer:

B is the correct answer

Answer:

Initial Number = x = 21

Number after it is decreased = y = 15

Total decrease form initial to the current number = z = x-y = 21-15 = 6

% of decrease = (z/x) * 100 = (6/21)*100 = 600/21 = 28.5714286 = 28.6 ( correcting it to 10th place)

Step-by-step explanation:

For 21 decreased to 15, the percentage decrease is 28.6%.

The percentage by which a number was decreased can be calculated by finding the difference between the original number and the decreased number, dividing that by the original number, and then multiplying by 100 to get the percentage.

Given number: 21

On reduction, number becomes: 15

The real interest rate of a savings account that has a nominal interest rate of 1% when the rate of inflation is 1% is B.) 0%

The real interest rate is the interest rate that is adjusted for inflation. It is calculated by subtracting the inflation rate from the nominal interest rate. In this case, the nominal interest rate is 1% and the inflation rate is also 1%.

So, the real interest rate is:

= 1% - 1%

= 0%

In other words, if you deposit $100 in a savings account with a nominal interest rate of 1%, you will earn $1 in interest after one year. However, because inflation is also 1%, the purchasing power of your $100 will decrease by $1. So, the real value of your savings will not change.

Final answer:

The real interest rate for a savings account with a nominal interest rate of 1% and an inflation rate of 1% is 0%. This is found by subtracting the inflation rate from the nominal interest rate.

Explanation:

The real interest rate is calculated by taking the nominal interest rate and subtracting the rate of inflation. In this case, if you have a nominal interest rate of 1% and an inflation rate of 1%, the real interest rate would be calculated as follows:

Real interest rate = Nominal interest rate - Inflation rate

Real interest rate = 1% - 1% = 0%

Therefore, the real interest rate for the savings account is 0%. This means that the purchasing power of the money in the savings account is essentially staying the same. The correct answer is B.) 0%.

Answer:

Step-by-step explanation:

Let:

s - side of the square

d - diameter of the circle

r - radius of a circle

C - circumeference of the circle

AC - area of the circle

AS - area of a square

The formula of a perimeter of a square:

P = 4s

We have P = 40cm.

Substitute:

4s = 40              divide both sides by 4

s = 10 cm

a.

The length of the diameter of the circle inscribed in the square is equal to the length of the side of the square.

Therefore d = s → d = 10 cm.

b.

The length of the circle diameter is two lengths of the circle radius.

Therefore d = 2r → r = d : 2 → r = 10 : 2 = 5 cm.

c.

The formula of a circumference of a circle:

C = dπ.

Substitute d = 10cm, and π = 3.14.

C = 10(3.14) = 31.4 cm.

d.

The formula of an area of a circle:

AC = πr²

Substitute r = 5cm and π = 3.14

AC = 3.14(5²) = 3.14(25) = 78.5 cm².

e.

The formula of an area of a square:

AS = s²

Substitute s = 10 cm

AS = 10² = 100 cm²
