Step-by-step explanation:

Excessive punishment or negative reinforcement can harm a child's math achievement by creating fear, undermining confidence, and discouraging engagement with the subject. Positive discipline techniques and a supportive environment are crucial for fostering math success.

Excessive punishment or negative reinforcement as a discipline technique can have detrimental effects on a child's math achievement. When a child makes mistakes or struggles with math concepts, responding with punishment, criticism, or harsh consequences can create a negative association with math. This can lead to anxiety, fear, and a lack of motivation to engage with the subject.

Mathematics requires a growth mindset, where mistakes are seen as opportunities for learning and improvement. By punishing or negatively reinforcing a child's math mistakes, we discourage them from taking risks, trying new strategies, and seeking help when needed. It hampers their ability to develop problem-solving skills and critical thinking abilities.

Furthermore, negative discipline approaches can damage a child's self-esteem and confidence in their mathematical abilities. They may develop a belief that they are "bad at math" or incapable of improving, leading to a self-fulfilling prophecy where their performance suffers.

To support a child's math achievement, it is essential to employ positive discipline techniques. This includes providing constructive feedback, offering assistance and guidance, creating a safe and supportive learning environment, and promoting a growth mindset. Encouraging effort, perseverance, and celebrating small successes can foster a positive attitude towards math and enhance a child's mathematical abilities.

Answer:

It's answer B, 49 hits. I got it right

If a function f is differentiable at a point a and f(a) is not equal to zero, then the absolute value function |f| is also differentiable at that point.

The proof involves considering two cases based on the sign of f(a) and showing that the limit of the difference quotient exists for |f| at point a in both cases. However, it is important to note that |f| is not differentiable at the point where f(a) equals zero.

To prove that if f is differentiable at a, then |f| is also differentiable at a, provided that f(a) ≠ 0, we need to show that the limit of the difference quotient exists for |f| at point a.

Let's consider the function g(x) = |x|. The absolute value function is defined as follows:

g(x) = {

x if x ≥ 0,

-x if x < 0.

Since f(a) ≠ 0, we can conclude that f(a) is either positive or negative. Let's consider two cases:

Case 1: f(a) > 0

In this case, we have g(f(a)) = f(a). Since f is differentiable at a, the limit of the difference quotient exists for f at point a:

lim (x→a) [(f(x) - f(a)) / (x - a)] = f'(a).

Taking the absolute value of both sides, we have:

lim (x→a) |(f(x) - f(a)) / (x - a)| = |f'(a)|.

Since |g(f(x)) - g(f(a))| / |x - a| = |(f(x) - f(a)) / (x - a)| for f(a) > 0, the limit on the left-hand side is equal to the limit on the right-hand side, which means |f| is differentiable at a when f(a) > 0.

Case 2: f(a) < 0

In this case, we have g(f(a)) = -f(a). Similarly, we can use the same reasoning as in Case 1 and conclude that |f| is differentiable at a when f(a) < 0.

Since we have covered both cases, we can conclude that if f is differentiable at a and f(a) ≠ 0, then |f| is also differentiable at a.

Note: It's worth mentioning that at the point where f(a) = 0, |f| is not differentiable. The proof above is valid when f(a) ≠ 0.

Dacia asks Katarina to tell her what the values of y are that can make sin θ negative. The correct answer is: "For y values greater than or equal to zero.

In the first quadrant (0 < θ < π/2), all trigonometric functions are positive.

In the second quadrant (π/2 < θ < π), only the sine is positive.

In the third quadrant (π < θ < 3π/2), only the tangent is positive.

Finally, in the fourth quadrant (3π/2 < θ < 2π), only the cosine is positive.

Therefore, sin θ is negative in the 3rd and 4th quadrants. In other words, for values of θ where sin θ is negative, you should look for θ values that fall in the 3rd and 4th quadrants.

Therefore, when Katarina responds to Dacia, "For y values greater than or equal to zero," it is incorrect as for the negative values of sin, θ must fall in the 3rd and 4th quadrants.

In a case whereby Tara is a sales representative for a cosmetic company. She is paid R5.15 per hour each week plus a commission of 10% on the amount of sales over R5 000, the job that would pay more is the second job because  R490.4 > R432. Yes she should change job.

The concept that will be used here is simplification.

We will need to know the amount that she gets from each job so as to know the job would pay more, this can be done as :

The first job:

R5.15*40hours * (7260-5000)*10%

=R5.15*40hours * (2260)*10%

=R432

Hence the salary here  is R432

The second job:

=40 hour* R5 + 7260 *4%

=40 hour* R5 + (7260 *4%)

= R490.4

Hence R490.4 > R432, therefore she should change job.

Adelaide's monthly payment for financing the refrigerator over 36 months at an APR of 12.5% is approximately $55.33

This calculation is based on the formula for calculating the monthly payment on a loan, taking into account the principal amount, the monthly interest rate, and the number of months.

In the first paragraph, we determine the principal amount as $1750, which represents the cost of the refrigerator. The annual percentage rate (APR) of 12.5% is converted to a monthly interest rate (r) by dividing it by 12 and then by 100. The number of months (n) is given as 36.

In the second paragraph, we substitute the values into the monthly payment formula and perform the necessary calculations. The formula incorporates the principal, the monthly interest rate, and the number of months to determine the monthly payment amount. After evaluating the expression, we find that Adelaide's monthly payment is approximately $55.33.

The critical value of f(x) = 5x⁶ - 3x⁵ is x = 0.5 which is also its maxima point

f(x) = 5x⁶ - 3x⁵

differentiation w.r.t x

=> f'(x) = 30x⁵ - 15x⁴

Putting f'(x) = 0

30x⁵ - 15x⁴ = 0

=> x⁴(30x - 15) =0

=> 30x - 15 = 0

=> x = 15/30

=> x = 0.5 , 0

Critical number is 0.5 , 0

(B) To find where f(x) is increasing

for x > 0.5 ,

(30x-15) > 0 => x⁴(30x - 15) > 0

Therefore , f(x) is increasing at ( 0.5 , ∞ )

(C)To find where f(x) is decreasing

for x < 0.5 ,

(30x-15) < 0 => x⁴(30x - 15) < 0

Therefore , f(x) is decreasing at ( -∞ , 0.5)

(D) Differentiation f'(x) again w.r.t to x

f'(x) = 30x⁵ - 15x⁴

f"(X) = 150x⁴ - 60x³

Substituting critical values of x

=> 150(0.5)⁴ - 60(0.5)³

=>9.375 - 7.5

The expected value E[X] and E[Y ]

 E[X+Y] = 39.2838 + 37 = 76.2838

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, broadly speaking, 0 represents the event's impossibility and 1 implies certainty.

E(X+Y) = E(X) + E(Y)

E[X] is the mean of X or the expected value of X.

E[Y] is the typical or expected value for Y.

E[X]= 40P (student in bus 1), 33P (student in bus 2), 25P (student in bus 3), and 50P (student in bus 4)

40(40/148) + 33(33/148) + 25(25/148) + 50(50/148) = 39.2838

E[Y] = (number of drivers)/(number of students), or 148/4, equals 37.

Answer:

area = 250.04 km^2

Step-by-step explanation:

In the image, we have the next figures.

One quart of a circle, with radius R = 12km

A large rectangle, with length L = 13km and width = 9 km

(to find the width of this rectangle, look at the bottom, we have a part of 5km, and then we have the small rectangle with a width of 4km, then 4km + 5km = 9km)

And finally, a smaller rectangle with length L = 5km and width W = 4km

Now, the general rules for each figure are:

The area of a circle of radius R, is

A = pi*R^2

with pi = 3.14

Here we have the fourth part of a circle with a radius R = 12km

Then the area of that part is:

area = (1/4)*3.14*(12km)^2 = 113.04 km^2

And the area of a rectangle of length L and width W is:

A = W*L

Then, the area of the larger rectangle is:

A' = 9km*13km = 117 km^2

And the area of the smaller rectangle is:

A'' = 4km*5km = 20km^2

The complete area of the figure is:

area = A + A' + A'' =  113.04 km^2 +  117 km^2 + 20km^2 = 250.04 km^2
