The given statement is true, the minute hand will point to the right of the viewer when the upside down hung clock reads 2:45.
Here, we are given that a round analog clock featuring numbers 1-12 is hung on the wall upside down.
In order to solve this question, we need to visualize the situation very carefully.
When we hang the clock upside down, the numbers will switch their positions among their opposite pair.
For example, number 12 will be at the place of number 6 and vice versa.
Similarly, number 9 will be at the place of number 3.
When the clock strikes 2:45, the minute hand is pointing towards number 9.
However, since the clock is hung upside down, number 9 is at the place of number 3.
Number 3 is on the right side of the viewer who is standing in front of the clock.
Thus, the given statement is true, the minute hand will point to the right of the viewer when the upside down hung clock reads 2:45.

What is the equation of a line passing through x1 y1 with slope?
The equation of a line passing through (x1, y1) is y - y1 = m(x - x1).
The equation of a line:
The equation of a line means an equation in x and y whose solution set is a line in the (x,y) plane. The most popular form in algebra is the "slope-intercept" form. y = mx + b. This in effect uses x as a parameter and writes y as a function of x: y = f(x) = mx+b.
Here we have to find the equation of a line passing through (x1, y1) and the slope.
Data given:
Point on the line = (x1, y1)
Slope = m
By this we get the equation of a line as:
y - y1 = m(x - x1)
Therefore the equation of a line is y - y1 = m(x-x1).

The features of the function are given as follows:
Horizontal asymptote: y = 5.Vertical asymptote: x = 2.x-intercept: No x-intercept.y-intercept: (0,-5).Hole: No holes.What are the features of the function?The horizontal asymptote is the limit of f(x) as x goes to infinity. To obtain this limit, we consider only the terms with the highest exponent of the numerator and of the denominator, hence:
g(x) = -5x/x -> y = 5 is the horizontal asymptote.
The vertical asymptote is the value of x for which the function is not defined, hence it is the zero of the denominator, thus:
x - 2 = 0 -> x = 2.
The x-intercept is the point (x,0), in which x is found when y = 0, hence:
-5x + 10 = 0
-5x = -10
5x = 10
x = 2.
However, the function is not defined at x = 2, meaning that it has no x-intercept.
The y-intercept is the value of y when x = 0, hence:
y = 10/-2 = -5.
The coordinates are (0,-5).
The entire function can be simplified as follows:
(-5x + 10)/(x - 2) = [-5(x - 2)]/(x - 2) = -5.
Meaning that the function has no holes.

Step-by-step explanation:
For this problem, we basically want to find 2016/96.
2016=1920+96. So, 2016/96 = (1920+96)/96=20+1=21.
So, the hot air balloon travels 21 miles each hour.
''21'' because 2016 divided by 96 is 21

(the variation is due to luck in guessing and the accident of the specific questions being familiar to the student.) the two scores are independent. what is the probability that the scores differ by 5 or more points in either direction? follow the four-step process.
The probability that the scores differ by 5 or more points in either direction is 0.0764.
According to the Question,
the mean and standard deviation of are
μₓ = 24
σₓ = 2
We have to find the probability of the scores differ by or more points on either direction.
Considering the X₁ and X₂ as the random variable, the scores of Leon and Fred.
Define the variable:
D = X₁ - X₂
We have to find : P(IDI ≥ 5)
According to the Question, the two scores are independent
The mean of :
D : μₐ = 0
The standard deviation of :
D : σₐ = 2.828
Standardizing the mean and standard deviation:
D = -5
Z = X - μₐ / σₐ
= -5 -0 / 2.828
= -1.77
Now, we standardize
D = 5
Z = X - μₐ / σₐ
= 5 -0/ 2.828
= 1.77
Now,
Calculating the probability:
Using a table of typical normal probabilities as a guide,
P(D ≤ -5) or P(D ≥ 5)
= P ( z ≤ - 1.77) + P( z ≥ 1.77)
= P(z ≥ 1.77) + P(Z ≥ 1.77)

how does omega change over time?how does omega change over time?it increases proportionally with a.it decreases proportionally with a.it increases quadratically with time.it decreases as a increases.
As the time increases, the angular velocity i.e. omega also increases quadratically with time.
Given,
From the figure,
Radius of wheel = 0.2 m
Acceleration, a = 4t m/s^2
then the angular acceleration of wheel can be determined by formula,
[tex]a=\alpha * r[/tex]
Where, r=radius of wheel =0.2 m
[tex]4t=\alpha * 0.2\\20t=\alpha[/tex]
We know that the angular acceleration is the change in angular velocity over time.
[tex]\alpha=\frac{d\omega}{dt}\\\\20t=\frac{d\omega}{dt}\\\\d\omega=20tdt\\\\\omega=\int\limits^t_0 {20t} \, dt \\\\\omega=\frac{20t^2}{2}-0\\\\\omega=10t^2[/tex]
From the above equation it is clear that omega i.e. angular velocity is dependent of time
omega is directly proportional to square of time
For
t=1 then ω=10
t=2 then ω=10(4)=40
t=3 then ω=10(9)=90.....and so on.

Both Marta and Khalid get an increase of £1.50 in their hourly pay.
The ratio of Marta’s hourly pay to Khalid’s hourly pay after this increase is 13 : 11
Work out the hourly pay before the increase for Marta and for Khalid
The hourly pay before the increase for Marta and for Khalid is $18 and $15 respectively.
Given that, the ratio of Marta’s hourly pay to Khalid’s hourly pay is 6:5.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Now, Marta’s hourly pay is 6x and Khalid’s hourly pay is 5x
Both Marta and Khalid get an increase of £1.50 in their hourly pay.
So, Marta’s hourly pay will be 6x+1.50 and Khalid’s hourly pay will be 5x+1.50
The ratio of Marta’s hourly pay to Khalid’s hourly pay after this increase is 13:11
Here, (6x+1.50)/(5x+1.50) =13/11
11(6x+1.50)=13(5x+1.50)
⇒ 66x+16.5=65x+19.5
⇒ x=3
So, Marta’s hourly pay is $18 and Khalid’s hourly pay is $15
Therefore, the hourly pay before the increase for Marta and for Khalid is $18 and $15 respectively.

Lucinda has created a square pyramid mold for sand art. The sides of the base are each 11 inches, and the pyramid is 15 inches tall. Lucinda plans to full the pyramid three fourths full with colorful sand. How many cubic inches of the pyramid will contain sand?
Answer:
453.75
Step-by-step explanation:
To find the volume of a pyramid, we can use the formula V = (1/3)Bh, where V is the volume of the pyramid, B is the area of the base, and h is the height of the pyramid.
Since the base of the pyramid is a square, we can use the formula for the area of a square to find the area of the base. The formula for the area of a square is A = s^2, where A is the area of the square and s is the length of one side of the square. In this case, each side of the square base is 11 inches, so the area of the base is 11^2 = 121 square inches.
Now that we know the area of the base, we can use the volume formula to find the volume of the pyramid. The height of the pyramid is 15 inches, so the volume of the pyramid is V = (1/3) * 121 * 15 = 605 cubic inches.
Since Lucinda plans to fill the pyramid three fourths full with sand, the volume of the pyramid that will be filled with sand is 3/4 * 605 = <<3/4*605=453.75>>453.75 cubic inches.
What is the equation of line passing through 3 4 and having slope 3 2?
The equation of the line passing through (3,4) and having slope m = 3/2 is y = 3/2x + 4.
Given points : (3,4)
The equation of a line with slope 3/2 and passing through point (3,4) is y = 3/2x + 4. This equation can be used to calculate the y-coordinate of any point on the line, given its x-coordinate. For example, if the x-coordinate of a point is 6, then its corresponding y-coordinate is 11. In general, for any x-coordinate, the corresponding y-coordinate is given by 3/2 times the x-coordinate plus 4.
Given slope : m = 3/2
We know that the equation of a line with slope m and passing through point (x1, y1)is given by :
y - y1 = m(x - x1)

y - 4 = 3/2(x - 3)

In number related terms: dy dt = ky where dy dt is the pace of progress in a moment, y is how much what we're discussing right then and there, and k is the consistent of proportionality. We need to use logarithmic functions to evaluate the values.
We are given function in form of x which is f(x) = 5×12ˣ,it is equivalent to
=>f(x)=5 × expo(ln(12ˣ)
=>f(x) =5 ˣ [tex]e(^1^2)^x[/tex]
On comparing with the given equation - a₀[tex]e^(k)^x[/tex] ,we get
=>a₀=5 and k=12.
Hence, required values are 5 and 12,
