Step-by-step explanation:

The angles that share the same sine value as sin(45°) have terminal sides in second quadrant .

The sine function relates the ratio of the length of the side opposite an acute angle to the length of the hypotenuse of a right triangle. The sine of an angle is always between -1 and 1.

The sine of 45 degrees is √2/2, which is a positive value. Since the sine of an angle is positive in the first and second quadrants, the angles that share the same sine value as sin(45°) must have their terminal sides in the first or second quadrant.

To find the angles that have the same sine value as 45 degrees, we can use the inverse sine function, also known as the arcsine function. The arcsine of √2/2 is 45 degrees or π/4 radians, which is an angle in the first quadrant.

However, since the sine function is periodic, there are infinitely many angles with the same sine value as 45 degrees, and they are all separated by integer multiples of 360 degrees or 2π radians.

Therefore, the angles that share the same sine value as sin(45°) have terminal sides in second quadrant, and can be represented by the formula:

θ = n(360°) ± 45°

or

θ = n(2π) ± π/4

where n is an integer.

Step-by-step explanation:

According to the question and after using the Pythagorean theorem the length of one side of the roof is 7.416 metres.

The Pythagorean Theorem is a mathematical formula used to determine the length of the sides of a right triangle. It is named after the Greek mathematician Pythagoras, who is credited with discovering the formula in the 6th century BC. The theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the hypotenuse (the longest side of the triangle). In equation form, it is expressed as a² + b² = c², where a and b are the lengths of the two shorter sides of the triangle and c is the length of the hypotenuse.

We know that the hypotenuse is 8 metres (the width of the shed) and the two shorter sides are 3 metres (the height of the walls) and y (the length of the side of the roof).
Therefore, using the Pythagorean theorem, we have:
3² + y² = 8²
9 + y² = 64
y² = 55
y = √55
y = 7.416 metres
Therefore, the length of one side of the roof is 7.416 metres.

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.

The equation of a parabola can be determined by analyzing its graph. The equation of a parabola can have various forms, so the general form allows for flexibility in its representation.

y = ax^2 + bx + c

To find the values of a, b, and c, we need to use the information provided by the graph of the parabola. Let's break down the steps:

1. Determine the vertex of the parabola:
  - The vertex is the lowest or highest point on the graph, depending on the orientation of the parabola.
  - Identify the coordinates of the vertex. Let's say it is (h, k).

2. Substitute the vertex coordinates into the equation:
  - Replace x with h and y with k in the equation: k = ah^2 + bh + c.

3. Use another point on the graph to find the equation:
  - Choose any other point (x1, y1) on the parabola.
  - Substitute the coordinates into the equation: y1 = ax1^2 + bx1 + c.

4. Solve the system of equations:
  - Set up a system of equations using the information from step 2 and step 3.
  - For example, if the vertex coordinates are (h, k) and the other point is (x1, y1), the system of equations would be:
    k = ah^2 + bh + c    (equation 1)
    y1 = ax1^2 + bx1 + c (equation 2)

5. Solve the system of equations for a, b, and c:
  - Use any method (substitution, elimination) to solve the system and find the values of a, b, and c.

6. Write the equation in general form:
  - Once you have the values of a, b, and c, substitute them into the equation y = ax^2 + bx + c to obtain the final equation of the parabola.

Remember, the equation of a parabola can have various forms, so the general form allows for flexibility in its representation.

Answer:

Ok, we have:

325*89.1

Let's decompose this into:

325 = 300 + 25

89.1 = 80 + 9 + 0.1

Then we have the multiplication:

(300 + 25)*(80 + 9 + 0.1)

Let's distribute the multiplication:

300*80 + 300*9 + 300*0.1 + 25*80 + 25*9 + 25*0.1

So now we have 6 multiplications that are a lot easier to solve than the initial one that we had.

Then the list of six multiplications involved in solving this problem are:

300*80 = 24,400

300*9 = 2,700

300*0.1 = 30

25*80 = 2,000

25*9 = 225

25*0.1 = 2.5

Now we add all of those and get:

325*89.1 = 24,400 + 2,700 + 30 + 2,000 +  225 + 2.5 = 28,957.5

False, the equality E(XY) = E(X)E(Y) does not hold if X and Y are dependent.

The equality E(XY) = E(X)E(Y) only holds if X and Y are independent random variables. If X and Y are dependent, this equality generally does not hold, and the covariance between X and Y needs to be taken into account.

The covariance between X and Y is defined as Cov(X,Y) = E[(X - E(X))(Y - E(Y))]. If X and Y are independent, then the covariance between them is zero, and E(XY) = E(X)E(Y) holds. However, if X and Y are dependent, the covariance between them is nonzero, and E(XY) is not equal to E(X)E(Y).

In fact, we can write E(XY) = E[X(Y-E(Y))]+E(X)E(Y), where E[X(Y-E(Y))] represents the "extra" contribution to the expected value of XY beyond what would be expected if X and Y were independent. This term represents the effect of the dependence between X and Y, and it is zero only if X and Y are uncorrelated.

Therefore, the equality E(XY) = E(X)E(Y) does not hold if X and Y are dependent.

The coffee will reach a temperature of 143 degrees Fahrenheit in approximately 18.67 minutes.

Newton's law of cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Mathematically, we can write this as:

dT/dt = -k(T - T_s)

where dT/dt is the rate of change of temperature with respect to time, T is the temperature of the object, T_s is the temperature of the surroundings, and k is a constant of proportionality.

In this problem, we are given that the coffee has a temperature of 200 degrees Fahrenheit when freshly poured and cools to 188 degrees Fahrenheit after 2 minutes in a room at 80 degrees Fahrenheit. Let's call the time at which the coffee reaches a temperature of 143 degrees Fahrenheit as t.

Using Newton's law of cooling, we can set up an equation as:

(dT/dt) = -k(T - T_s)

Integrating both sides, we get:

ln(T - T_s) = -kt + C

where C is a constant of integration.

Using the initial conditions, we can solve for C:

ln(200 - 80) = -k(0) + C

C = ln(120)

So the equation becomes:

ln(T - 80) = -kt + ln(120)

Now we can use the fact that the temperature of the coffee has cooled to 188 degrees Fahrenheit after 2 minutes to find the value of k:

ln(188 - 80) = -k(2) + ln(120)

k = (ln(120) - ln(108)) / 2

k ≈ 0.0776

Now we can solve for the time t when the coffee reaches a temperature of 143 degrees Fahrenheit:

ln(143 - 80) = -0.0776t + ln(120)

t ≈ 18.67 minutes

Therefore, the coffee will reach a temperature of 143 degrees Fahrenheit in approximately 18.67 minutes.

Step-by-step explanation:

it was correct for me

The percent error of Li’s guess is 15%

"It is the absolute difference between an observed value and the actual value."

"It is the ratio of the absolute error of the measurement to the actual value."

"It is the relative error multiplied by 100."

For given example,

Li’s guess is 345 jelly beans.

observed value (E) = 345

The actual number of jelly beans is 300

actual value (A) = 300

So, the absolute error is,

Absolute error = |E - A|

                        = | 345 - 300|

                        = 45

Now, we find the relative error of Li's guess.

Relative error = 45 ÷ 300

Relative error = 0.15

The percent error is,

0.15 × 100 = 15%

Therefore, the percent error of Li’s guess is 15%
