a. The teacher's age in seconds can be written in scientific notation as 1.5 × \(10^{9}\) seconds.
b. A more reasonable unit of measurement for this situation could be years, as it is a common unit used to express human age.
c. To convert the teacher's age from seconds to years, we can divide the number of seconds by the number of seconds in a year. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and approximately 365 days in a year. So,
1.5 × \(10^{9}\) seconds ÷ (60 seconds/minute × 60 minutes/hour × 24 hours/day × 365 days/year) = approximately 47.5 years
Therefore, the teacher is approximately 47.5 years old when using the more reasonable unit of measurement.

The are of the triangle below is 28.8 square centimeters. What is the length of the base?
Take into account that the formula for the area of a triangle is:
A = b·h/2
where b is the base, h is the height h = 7.2 cm and A is the area A = 28.8 cm²
Solve for b in the previous formula, and replace the values of A and h, as follow:
b = 2·A/h
b = 2(28.8 cm²)/(7.2 cm)
b = 8 cm
Hence, the length of the base of the triangle is 8 cm

Step-by-step explanation:
A meteorologist is measuring the temperature every 15 minutes. She notices the temperature increases by 3/4 degrees Fahrenheit between each measurements for 2 hours. What is the rate per hour of the temperature increase?
Answer:
3 °F/h
Step-by-step explanation:
The rate per hour of temperature change = change in temperature per measurement/change in time per measurement.
Now, the change in temperature per measurement is constant = 3/4 °F and the change in time per measurement is constant = 15 minutes = 15/60 h = 1/4 h.
So, rate per hour of temperature change = change in temperature per measurement/change in time per measurement
= 3/4 °F ÷ 1/4 h
= 3/4 °F × 4/h
= 3 °F/h
So, the rate per hour of temperature change is 3 °F/h
is the line through (-4, 26, 1) and (-2, 0, -3) parallel to the line through (10, 18, 4) and (5, 3, 14)?
No, the line passing through (-4, 26) and (-2, 0) is not parallel to line passing through (10, 18) and (5, 3) because slopes of both lines are different.
Line is possible in 2-d forms so, it has only x and y-co-ordinates. Z-co-ordinates is not possible.
We know very well that to prove any two lines are parallel to each other we need to prove only whether their slopes are equal or not.
Now, talking about the slopes we know that if any line is passing from point(x₁,y₁) and again passing from other point(x₂,y₂) then slope(m) of that line is given by the formula=(y₂-y₁) / (x₂-x₁)
So, for first line we have (x₁, y₁)=(-4,26)
and (x₂, y₂)=(-2,0)
So, slope(m₁) of first line is =(0-26)/(-2 - (-4))
=>m₁ = -26/2
=>m₁ = -13 ----(eq1)
Similarly, for second line, we have (x₁, y₁)=(10,18)
and (x₂, y₂)=(5,3)
So, slope(m₂) of second line is =(3-18) / (5-10)
=>m₂ = -15/-5
=>m₂= 3 -------(eq2)
On comparing eq1 and eq2,we get
=>m₁≠m₂.
Hence, the given lines are not parallel.

For the rhombus below, find the measures of angles 1, 2, 3, and 4.
The measure of angles inside the rhombus are:
∠1 = 56
∠2 = 56
∠3 = 34
∠4 = 34
We have,
In a rhombus,
The opposite angle is congruent.
So,
(56 + 56) = ∠1 + ∠2
And,
∠1 and ∠2 are equal angles.
So,
112 = 2∠1
∠1 = 56
∠2 = 56
Now,
All four angles in side the rhombus = 360
112 + 112 + ∠x + ∠x = 360
2∠x = 360 - 224
2∠x = 136
∠x = 68
This ∠x is the angle inside the rhombus.
And, ∠x/2 = ∠3 = ∠4
So,
∠3 = 68/2 = 34
∠4 = 34

Question 6 of 10 > Do people have a preference for the last thing they taste? Researchers at the University of Michigan designed a study to find out. The researchers gave 22 students five different Hershey's Kisses (milk chocolate, dark chocolate, crème, caramel, and almond) in random order and asked the student to rate each candy. Participants were not told how many Kisses they would taste. However, when the 5th and final Kiss was presented, participants were told that it would be their last one. Assume that the participants in the study don't have a special preference for the last thing they taste, that is, the probability of preferring the last Kiss tasted is p = 0.20. Let X = the number of participants who choose the last Kiss. Of 22 students, 14 gave the final Kiss the highest rating. (a) Find P(X≥ 14). Round to 5 decimal places. Leave your answer in decimal form.
It should be noted that the probability for P(X ≥ 14) rounded to 5 decimal places is approximately 0.17026.
How to calculate the probabilityP(X ≥ 14) = P(X = 14) + P(X = 15) + ... + P(X = 22)
Let's calculate P(X ≥ 14):
P(X = 14) = (22 choose 14) * (0.20^14) * (0.80^8)
P(X = 15) = (22 choose 15) * (0.20^15) * (0.80^7)
P(X = 16) = (22 choose 16) * (0.20^16) * (0.80^6)
P(X = 17) = (22 choose 17) * (0.20^17) * (0.80^5)
P(X = 18) = (22 choose 18) * (0.20^18) * (0.80^4)
P(X = 19) = (22 choose 19) * (0.20^19) * (0.80^3)
P(X = 20) = (22 choose 20) * (0.20^20) * (0.80^2)
P(X = 21) = (22 choose 21) * (0.20^21) * (0.80^1)
P(X = 22) = (22 choose 22) * (0.20^22) * (0.80^0)
Calculating each probability and summing them up:
P(X ≥ 14) = P(X = 14) + P(X = 15) + ... + P(X = 22)
= 0.17026
Therefore, P(X ≥ 14) rounded to 5 decimal places is approximately 0.17026.

Problems 1- 14, use the rules of differentiation to find the derivative of the function. 1. y = 14; 2. y=x^9+3 tan x; 3. y = 1/x^4-4cos x
1 . y'=0 is the derivative of the function y = 14.
2. y' = 9\(x^8\)+3\(sec^2x\) is the derivative of the function y= \(x^9\)+3tanx
3. y' = \(\frac{-4}{x^5}\) + 4sinx is the derivative of the function y = \(\frac{1}{x^4}\) - 4cos x
1 . The derivative of a constant is always zero.
A constant function is a function whose value does not depend on the input value.
So y = 4 is a constant function, its derivative is always zero.
So the derivative of y=4 is 0
2. The differentiation of \(x^9\)+3tanx is 9\(x^8\)+3\(sec^2x\)
The power rule states that the derivative of x^n (where n is a constant) is nx^(n-1). So the derivative of x^9 is 9x^8.
The derivative of tanx is \(sec^2x\).
And the derivative of 3tanx is 3\(sec^2x\)
So, \(x^9\)+3tanx is differentiated as9\(x^8\)+3\(sec^2x\)
3. The derivative of y = \(\frac{1}{x^4}\) - 4cos x can be found using the power rule and the chain rule.
The power rule states that the derivative of x^n (where n is a constant) is nx^(n-1). In this case, \(\frac{1}{x^4}\) can be rewritten as \(\frac{1}{x^4}\) and the derivative would be -4 \(\frac{1}{x^5}\)
The chain rule states that the derivative of (f(g(x)) is f'(g(x))*g'(x). In this case, the inner function is -4cos x, the derivative of cos x is -sin x and the outer function is , \(\frac{1}{x^4}\) the derivative of that is -4 \(\frac{1}{x^5}\). So the derivative of -4cos x is -4(-sin x)
So the final derivative of y = \(\frac{1}{x^4}\) - 4cos x is \(\frac{-4}{x^5}\) + 4sinx

The function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)
From the first graph:
The line goes through the points:
(-2, 2) and (2, 1)
y - 1 = (1-2)/(2+2)[x -2]
y - 1 = (-1/4)[x -2]
y = -x/4 + 1/2 + 1
y = -x/4 + 3/2
The constant additive rate of change = -1/4
Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.

No, the sample size is too small and we do not know if the sample comes from a population with an approximately normal distribution Yes, the sample size is large enough to perform the test, whether or not the population is normally distributed • Yes, the sample size is small, but we know the sample comes from a population with an approximately normal distribution
: no, the sample size is too small and we do not know if the sample comes from a population with an approximately normal distribution.
in this scenario, we are given a sample of 12 one-cup servings of asparagus and asked whether it is appropriate to use the methods of hypothesis testing to make inferences about the population mean thiamine level.
to answer this question, we need to consider the sample size and the assumption of normality. in general, when the sample size is small (less than 30) and/or the population distribution is not approximately normal, we may need to use alternative methods for hypothesis testing.
in this case, the sample size is small (n = 12), which may pose a challenge for using the methods of hypothesis testing. additionally, while we are told to assume the population is approximately normal with a known standard deviation, we do not know for certain whether this assumption holds true for the sample. this means that we may need to use alternative methods, such as non-parametric tests, to make inferences about the population mean thiamine level.

The film thickness of the falling liquid film along the vertical surface is 3x10^-6 meters.
To calculate the film thickness of a falling liquid film along a vertical surface, we can use the equation:
Film thickness = (flow rate / (width * density)) * kinematic viscosity
Given the following values:
Flow rate = 6 kg/second
Width = 2 m
Density = 1x10^3 kg/m^3
Kinematic viscosity = 2x10^-4 m^2/s
Let's substitute these values into the equation:
Film thickness = (6 kg/second) / (2 m * 1x10^3 kg/m^3) * (2x10^-4 m^2/s)
First, we can simplify the units:
Film thickness = (6 / (2 * 1x10^3)) * (2x10^-4)
Now, let's perform the calculations:
Film thickness = (6 / 2000) * (2x10^-4)

Since from sentence 6 we know ¬C, we can apply modus ponens to sentence 7:
If sentence 6 states that ¬C is true, and sentence 7 presents a conditional statement with C as the antecedent and Q as the consequent, we can use modus ponens to infer that Q is false.
Modus ponens is a deductive reasoning rule that allows us to derive a conclusion from a conditional statement and its antecedent. Therefore, we can apply modus ponens to sentence 7 given that we know ¬C from sentence 6.
Since from sentence 6 we know ¬C, we can apply modus ponens to sentence 7. To do this, follow these steps:
1. Identify the premises: One premise is sentence 6, which states ¬C. The other premise should be a conditional statement, such as "If ¬C, then P" (replace P with the relevant proposition).
2. Apply modus ponens: Modus ponens is a rule of inference that allows us to deduce a conclusion from the given premises. If we have the premises "If ¬C, then P" and "¬C", we can conclude "P" using modus ponens.
3. State the conclusion: After applying modus ponens, we can conclude "P" based on the given premises, which include sentence 6 (¬C) and the conditional statement.

Answer:
x = 11.375
y = 23.75
Step-by-step explanation:
Corresponding angles: A pair of angles that are in the same relative position at each point where a straight line intersects two other straight lines.
If the two lines are parallel, the corresponding angles are equal.
Therefore:
⇒ (6x + 11)° = (3y + 8)°
⇒ 6x + 11 = 3y + 8
⇒ 6x + 3 = 3y
⇒ 3y = 6x + 3
Angles on a line sum to 180°.
Therefore:
⇒ (3y + 8)° + (10x - 13)° = 180°
⇒ 3y + 8 + 10x - 13 = 180
⇒ 3y + 10x = 185
⇒ 3y = 185 - 10x
Substitute the first equation into the second equation and solve for x:
⇒ 6x + 3 = 185 - 10x
⇒ 16x = 182
⇒ 16x = 182
⇒ x = 11.375
Substitute the found value of x into one of the equations and solve for y:
⇒ 3y = 6(11.375) + 3
⇒ 3y = 68.25 + 3
⇒ 3y = 71.25
⇒ y = 23.75
