1. What properties of quadratic functions cause this "death ray" effect?
2. Using the diagram below, what is the point called where the sun's rays are concentrated? Will the "death ray" always hit the same spot? Why?
2. Could this property of quadratic functions be helpful in a different situation? Explain
The properties of quadratic functions cause this "death ray" effect is discussed below.
The "death ray" effect refers to the phenomenon where a quadratic function appears to have a sharp point or vertex that shoots off to infinity in a graph. This effect is caused by the properties of quadratic functions, specifically:
The degree of the quadratic function: Quadratic functions have a degree of 2, which means they have a leading term that is a squared variable (x²). This leads to a graph that is a parabola.
The coefficient of the squared term: The coefficient of the squared term in the quadratic function determines the shape of the parabola. If the coefficient is positive, the parabola opens upward, and if the coefficient is negative, the parabola opens downward.
However, when the coefficient of the squared term is negative (a < 0), the graph of the quadratic function opens downward, and the vertex represents the maximum point of the parabola.

a train of length 180 m approaches a tunnel of length 620 m. how long will it take the train to pass completely through the tunnel at a speed of 54 km per hour?
It will take the train 53.33 seconds to pass completely through the tunnel.
We have,
First, let's convert the speed from km/h to m/s:
54 km/h = 54000 m/3600 s = 15 m/s
We need to find the total distance the train travels, which is the sum of its length and the tunnel's length:
So,
distance = 180 m + 620 m = 800 m
Now we can use the formula:
time = distance/speed
time = 800 m / 15 m/s
time = 53.33 seconds

B. any value of x that is less than or equal to 6.25 will work for Kiran.
c. One can use x ≤ 6.25 to show all the values that would work for Kiran.
d. The answer to Kiran's question can be written using mathematical notation as:
Kiran can be able to take out a maximum of $6.25 every month to make sure that he has at least $25 in the account a year from that time now.
What is the statement about?Since the inequality is -12x + 100 ≥ 25, the term -12x stands for the amount Kiran takes out each month. It is seen as a negative value because it stands for the monthly withdrawals from the said account.
b. To find values of x that would work for Kiran, it can be done by:
-12x + 100 ≥ 25.
-12x + 100 ≥ 25
So, subtract 100 from both sides:
-12x ≥ 25 - 100
-12x ≥ -75
Then divide both sides by -12 ( dividing by a negative number changes the inequality sign) Hence it will be:
x ≤ (-75) / (-12)
x ≤ 6.25
So, any value of x that is less than or equal to 6.25.
c. One can use x ≤ 6.25 to show all the values that would work for Kiran. based on the fact that:

[tex]x = \frac{56.9 + 55.9 + 52.5 + 65.7 + 59.0 + 64.7 + 70.1 + 64.7 + 53.5 + 78.2}{10}\\\\ = 62.3% \\\\\\\\S = \sqrt{\frac{((56.9 - 62.3)^2 + (55.9 - 62.3)^2 + ... + (78.2 - 62.3)^2) }{ 9}}\\\\ = 8.08\%[/tex]
Therefore, the sample mean percentage x is 62.3% and the sample standard deviation S is 8.08%.
(b) To find a 90% confidence interval for the population average u of the percentage of hospitals providing at least some charity care, we can use the formula:
[tex]CI = x \pm z*(S/sqrtn)[/tex]
where CI is the confidence interval, x is the sample mean percentage, z is the z-score for the desired confidence level (90% in this case), S is the sample standard deviation, and n is the sample size (10 in this case).
From the z-table, the z-score for a 90% confidence level is 1.645.
Plugging in the values, we get:
CI = 62.3 ± 1.645*(8.08/sqrt(10)) = (55.5%, 69.1%)
Therefore, we can be 90% confident that the true population average percentage of hospitals providing at least some charity care is between 55.5% and 69.1%.

The value of the missing angle x is: 38°
How to find the angle of the parallelogram?We know that the sum of angles in a triangle is 180 degrees and as such:
∠DAE = 180 - (82 + 68)
∠DAE = 30°
Now, we know that alternate angles are congruent. Thus:
∠DAE ≅ ∠ADC = 30°
Opposite angles of a parallelogram are equal (or congruent) Consecutive angles are supplementary angles to each other (that means they add up to 180 degrees).
Thus:
∠BAE = ∠BDE = 82 + 30
= 112°
Thus:
∠ABC = ∠ACB = 68°
Thus:
∠BAC = 180 - 2(68)
∠BAC = 44°
Thus:
x = 112 - (44 + 30)
x = 112 - 74
x = 38°

The exact values are:
sin(α + β) = (-6√5 - 8)/25
cos(α + β) = (4√5 - 6)/25
sin(α - β) = (-6√5 + 8)/25
tan(α - β) = (-9√5 + 45)/4
We have,
Recall the trigonometric identities:
sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
cos(a + b) = cos(a)cos(b) - sin(a)sin(b)
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
cos(a - b) = cos(a)cos(b) + sin(a)sin(b)
tan(a - b) = (tan(a) - tan(b))/(1 + tan(a)tan(b))
Using these identities, we can find the exact values of the expressions given.
(a) Sin (α + β)
sin(α + β) = sin(α)cos(β) + cos(α)sin(β)
= (√5/5)(-3/5) + (2/5)(-4/5) (using the values given for sin and cos)
= -6√5/25 - 8/25
= (-6√5 - 8)/25
(b) Cos (α + β)
cos(α + β) = cos(α)cos(β) - sin(α)sin(β)
= (2/5)(-3/5) - (√5/5)(-4/5) (using the values given for sin and cos)
= -6/25 + 4√5/25
= (4√5 - 6)/25
(c) Sin (α - β)
sin(α - β) = sin(α)cos(β) - cos(α)sin(β)
= (√5/5)(-3/5) - (2/5)(-4/5) (using the values given for sin and cos)
= -6√5/25 + 8/25
= (-6√5 + 8)/25
(d) tan (α - β)
tan(α - β) = (tan(α) - tan(β))/(1 + tan(α)tan(β))
= ((√5/5) - (-4/5))/(1 + (√5/5)(-4/5)) (using the values given for sin and cos)
= (9√5/5)/(1 - 4/5√5)
= (-9√5 + 45)/4
Therefore,
The exact values are:
sin(α + β) = (-6√5 - 8)/25
cos(α + β) = (4√5 - 6)/25
sin(α - β) = (-6√5 + 8)/25
tan(α - β) = (-9√5 + 45)/4

What is the value of S?
The value of s in the circle is 11.
We have,
When two chords in a circle have the same arc length intercepted by the chords, it means that the distances from each endpoint of the chords to the center of the circle are equal.
Now,
The arc length XY and WZ are the same.
This means,
Chord XY and Chord WZ are equal.
Now,
2s = s + 11
Solve for s.
2s - s = 11
s = 11
Thus,
The value of s in the circle is 11.
