The new mandated change is, grade 4N's physical education class will end at 2:23 PM.

Physical education for grade 4N typically lasts 30 minutes and begins at 1:43 PM and concludes at 2:13 PM (2:13 PM - 1:43 PM).

Let's assume that the newly required adjustment extends the end of the class by 10 minutes, making the time change (c) 10 minutes.

Adding the time modification to the existing end time will yield the new end time:

2:13 PM + 10 minutes = 2:23 PM

So, with the new mandated change, grade 4N's physical education class will end at 2:23 PM.

Step-by-step explanation:

Hope this helps : )

The answer to the expression 2b x b is simply 2b^2. Exponentiation is a mathematical operation that raises a number to a power, and in this case, b is raised to the power of 2.

Alternatively, if exponentiation is not allowed, the answer to the expression is simply 2b * b, which can be simplified to 2b^2 as well.

So, the answer to the expression 2b x b is 2b^2, regardless of whether or not exponentiation is used.

The expression 2b x b represents the product of two scalars, 2 and b, multiplied by a scalar b.

The expression could represent a variety of quantities in mathematics and science, including the area of a rectangle, the volume of a cube, or the kinetic energy of an object, among others.

The fraction that satisfies the problem is 20/24.

Equivalent fractions are fractions that have the same value, but different numerators and denominators.

If the fraction is equivalent to 5/6, then the numerator and denominator of the fraction is a multiple of 5 and 6, respectively.

Let x be the factor

fraction = 5x / 6x

If the sum of my numerator and my denominator is 44, then:

5x + 6x = 44

11x = 44

x = 4

fraction = 5x / 6x = 20/24

The final statement says that the sum of the digits in the denominator is 6.

2 + 4 = 6

Hence, the fraction is 20/24.

Answer: Let's denote the length of the candle on day 1 as L.

On day 2, the length of the candle is L/2, on day 3 it is L/2^2, on day 4 it is L/2^3 and on day 5 it is L/2^4.

So, on day 5, the length of the candle is L/2^4 = L/(222*2) = L/16.

Given that the length of the candle on day 1 is 18 inches, we have:

L = 18

And the length of the candle on day 5 is:

L/16 = 18/16 = 9/8

So, the length of the candle on day 5 is 9/8 inches.

The measure of the arc in degrees is 137.50°

An angle is said to have a measure of 1 radian if it is subtended at its center by an arc of lengths 1 unit in a unit circle. "rad" is the sign used to represent the radian unit of measurement.  

Here we have

An arc of a circle that measures 2.4 radians.  

We need to find the measure in degrees  

As we know 1 radian = 180°/π

2.4 radians = [ 180/π ] × 2.4 degrees  

= [57.324] × 2.4

= 137.57°  ( approx)

Answer:

  A  { y | y ∈ ℝ, y ≠ -4, -3 }

Step-by-step explanation:

You want to know the range of the function shown in the graph.

The range is the vertical extent of the graph, the set of possible function output values.

Here, the function approaches the horizontal asymptote y = -3, but never has that output value. The "hole" at (5, -4) means the function never has the output value -4, either.

The range is all real numbers (ℝ) except -4 and -3.

The transformations of the triangle ABC to A'B'C' are (a) and (e)

From the question, we have the following parameters that can be used in our computation:

ABC = (-6, 2), (-4, 6) and (-2, 2)

Rotate the triangle by 180 degrees

So, we have the following representation

Image 1 of ABC = (6, -2), (4, -6) and (2, -2)

Translate the triangle 1 units left

So, we have the following representation

A'B'C' = (5, -2), (3, -6) and (1, -2) ---- option (a)

Another possible sequence is as follows

Reflect the triangle across the x and y axes

So, we have the following representation

Image 1 of ABC = (6, -2), (4, -6) and (2, -2)

Translate the triangle 1 units left

So, we have the following representation

A'B'C' = (5, -2), (3, -6) and (1, -2) ---- option (e)

The three-digit palindromes are of the form: ABA.

Here, A can be selected in 4 ways.

Digits can be repeated hence, B can be selected in 4 ways.

The last A is the same number as the first A, hence the selection is 1 way.

Answer:

Step-by-step explanation:

All the real solutions of f(x) = 0 are 4, -2, and -5.  We know y = f(x) and f(x) = 0.  So, we can conclude that y = 0.  When y = 0, it means there isn't a point that moves up or down the y axis (vertically).  The point would only move horizontally.  When looking at the points on the x-axis, we see 4, -2, and -5.  Those are on the x-axis and haven't moved vertically.  So, the coordinates for those points would be 4, 0, -2, 0, and -5, 0.  Remember, y = 0, and 4, -2, and -5 all have a zero in the y value.  Therefore, the answer is 4, -2, and -5.
