Final answer:

The net change in temperature over the day is 0 degrees. After increasing by 17 degrees in the afternoon, the temperature fell by 17 degrees by nightfall, returning it to the starting temperature.

Explanation:

The student has asked about calculating the net change in temperature over the course of a day starting at 48 degrees. By 3:00 p.m., the temperature increased by 17 degrees, making it 65 degrees. But by nightfall, the temperature decreased by the same amount, falling back down to 48 degrees. The calculation of net change in this scenario is simple: subtract the starting temperature from the final temperature after all changes have occurred. In this case, the starting temperature was 48 degrees, it went up to 65 degrees, and then back to 48 degrees.

The net temperature change is therefore 48 degrees (final temperature) - 48 degrees (starting temperature), which equals 0 degrees. This means there was no net change in temperature over the course of the day. It is important to recognize that even though there was a temporary increase and subsequent decrease, the net effect cancels out, leaving the temperature the same as it started.

Answer:

  You can use either of the following to find "a":

Step-by-step explanation:

It looks like you have an isosceles trapezoid with one base 12.6 ft and a height of 15 ft.

I find it reasonably convenient to find the length of x using the sine of the 70° angle:

  x = (15 ft)/sin(70°)

  x ≈ 15.96 ft

That is not what you asked, but this value is sufficiently different from what is marked on your diagram, that I thought it might be helpful.

__

Consider the diagram below. The relation between DE and AE can be written as ...

  DE/AE = tan(70°)

  AE = DE/tan(70°) = DE·tan(20°)

  AE = 15·tan(20°) ≈ 5.459554

Then the length EC is ...

  EC = AC - AE

  EC = 6.3 - DE·tan(20°) ≈ 0.840446

Now, we can find DC using the Pythagorean theorem:

  DC² = DE² + EC²

  DC = √(15² +0.840446²) ≈ 15.023527

  a ≈ 15.02 ft

_____

You can also make use of the Law of Cosines and the lengths x=AD and AC to find "a". (Do not round intermediate values from calculations.)

  DC² = AD² + AC² - 2·AD·AC·cos(A)

  a² = x² +6.3² -2·6.3x·cos(70°) ≈ 225.70635

  a = √225.70635 ≈ 15.0235 . . . feet

To convert 1,700 meters to feet, we multiply by the conversion factor of 3.28 feet per meter, resulting in a length of 5,576 feet for the train.

To find the length of the train in feet, we need to convert meters to feet using the conversion factor provided. Given that 1 meter is approximately 3.28 feet, we can calculate the length of the train in feet by multiplying the length of the train in meters (1,700 meters) by the conversion factor (3.28 feet per meter).

The calculation would be as follows:

1,700 meters × 3.28 feet/meter = 5,576 feet

Therefore, the length of the train is 5,576 feet.

Final answer:

The measure of the angle of rotation that will map vertex S onto vertex U in a regular pentagon is 72 degrees.

Explanation:

The student is asking about an angle of rotation in a geometric context, specifically concerning mapping one vertex of a regular pentagon onto another through rotation about the center of the shape. In a regular pentagon, the angles between adjacent vertices are all equal, as it is a symmetrical shape. Since there are five vertices in a pentagon, you can divide the full rotation of 360 degrees by the number of vertices to find the angle of rotation that will map one vertex onto the next.

To map vertex S onto vertex U in a regular pentagon, you will need to rotate the pentagon by 360 degrees divided by 5 vertices, which is 72 degrees. Therefore, a rotation of 72 degrees around the center point X of the pentagon will map S onto U.

The statement is false. An equation's solutions are points on a line; an inequality's solutions encompass a region on the plane.

The statement is false. The solutions to a linear equation are the points (x, y) in the plane that make the equation true, not an inequality. An equation represents a line on the coordinate plane, and every point on that line is a solution to the equation. In contrast, an inequality describes a range or region of the coordinate plane, not just a single line, and the solutions are the coordinates within that range.

For instance, the solutions to the equation y = 2x + 3 are all the points on the line where this is true. On the other hand, solutions to the inequality y > 2x + 3 would be all the points in the region above the line y = 2x + 3.

The assertion that solutions to a linear equation are the points that make an inequality true is incorrect. It is the solutions to a linear inequality that would make the inequality true.

The statement provided in the question is false. Solutions to a linear equation are the points on the line that make the equation true, not an inequality. If we are dealing with a linear inequality, then its solutions are the points in the plane that satisfy the inequality, often forming a region, instead of just the points on a line.

AB is bisected by CD (TRUE). This is True because E is the midpoint between A and B and CD passes through E

CD is bisected by AB (FALSE) CD is bisected by point F and not AB

AE = 1/2 * AB (TRUE) since E is the midpoint of AB , E divides AB into two equal halves

EF = 1/2 * ED (FALSE) The true statement would have been CF = 1/2* CD

FD = EB (FALSE) sinc we do not know if CD and AB are of the same lengths

CE + EF = ED (TRUE) since F is the midpoint the sum of CE and EF is equal to ED

The statements for the line AB and CD for this condition that are true are given as:

Option A: [tex]\overline{AB}[/tex] is bisected by [tex]\overline{CD}[/tex]

Option C: [tex]AE = \dfrac{1}{2} \times AB[/tex]

Option F: CE + EF = FD

A bisector of a line bisects that considered line. Bisect means to split in two equal parts.

For this case, we see that CD passes through mid point of AB, so CD is bisector of line AB or we say that line segment AB is bisected by line segment CD.

But AB does not passes through the center of AB, thus, AB is not a bisector of CD, or we say that line segment CD is not bisected by line segment AB

AE = EB

And AE + EB = AB

Thus, AE + AE + AB

or 2AE = AB

or AE = (AB)/2 = (1/2)AB

E is not necessary to be fixed on CD, it can move between C and F. Thus any statement about length of E to any point on CD is not necessary to be true.

FD is half of CD and EB is half of AB. It is not necessary that AB and CD are of same length, thus, it is not necessary that FD and EB are going to be of same length, thus, not congruent(two line segments are called congruent (denoted by ≅) if they are of same lengths).

CE + EF = CF, and CF = FD since F is midpoint.

Thus, CE + EF = FD

Thus, the statements for the line AB and CD for this condition that are true are given as:

Option A: [tex]\overline{AB}[/tex] is bisected by [tex]\overline{CD}[/tex]

Option C: [tex]AE = \dfrac{1}{2} \times AB[/tex]

Option F: CE + EF = FD

The equation of the parabola with the vertex at (2,7) and passing through (-1,3) is y = -(4/9)(x - 2)^2 + 7, found by substituting the given points into the vertex form of a parabola's equation.

To find the equation of a parabola given its vertex and a point it passes through, we use the vertex form of a parabola's equation, which is y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Given the vertex at (2,7) and a point (-1,3) through which the parabola passes, we substitute these values into the vertex form to find the value of 'a'.

Substituting the vertex, we have:

y = a(x - 2)^2 + 7

Then, substituting the point (-1,3) into the equation, we get:

3 = a(-1 - 2)^2 + 7

Solving for 'a', we get:

3 = a(3)^2 + 7 \n3 = 9a + 7 \n-4 = 9a \na = -4/9

Therefore, the equation of the parabola is:

y = -(4/9)(x - 2)^2 + 7

The correct equation to solve for x, given that angle LOM (measured as (x + 15)°) and angle MON (measured as 48°) are complementary, is (x + 15)° + 48° = 90°. Thus, the answer is option D.

The subject of this question is Mathematics, specifically it refers to geometry, solving for a variable, and understanding the concept of complementary angles. Let's analyze the options provided.

Two angles are said to be complementary if the sum of their measure is 90 degrees. So, if angle LOM and angle MON are complementary, the sum of m∠LOM and m∠MON should be 90°. Since the measure of m∠LOM is given as (x + 15)° and the measure of m∠MON is given as 48°, the equation that represents this relationship is (x + 15)° + 48° = 90°.

Therefore, option D is the correct choice to solve for x.
