Answer:
o answer this question, we need to apply the transformations in the reverse order. So first, we need to apply the translation according to the rule (x+3,y-3). This means that the coordinates of the triangle will become A'(7,2), B'(0,3), and C'(2,5). Next, we need to reflect the triangle across the line y=0. This means that the y-coordinates of the triangle will become negative. So the coordinates of the triangle will become A''(7,-2), B''(0,-3), and C''(2,-5). Finally, we need to rotate the triangle 90 degrees. In a standard cartesian coordinate system, a rotation of 90 degrees counterclockwise is equivalent to the transformation (x, y) -> (-y, x). So the final coordinates of the triangle will be A'''(-2,7), B'''(-3,0), and C'''(-5,2).

How to compare the expression?From the question, we have the following parameters that can be used in our computation:
4 and fraction 8 over 4
Rewrite the above expression using mathematical operators and mathematical symbols
So, we have the following representation
4 and 8/4
The above expression are integers and fraction expressions
So, we express 8/4 as an integer
This gives

David has a coin collection. He keeps 9 of the coins in his box, which is 2% of the collection. How many total coins are in his collection?
Multiply/scale up to solve.
Total Coins in the collection are 450 units
What is Percentage?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. The percent symbol, "%," is commonly used, however the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.
Solution:
Given that 9 is 2% of the total collection
Let, total collection be x
2% of x is 9
2/100 * x = 9
x = 9 * 50 = 450

What is the relation between scale factor and sensitivity of a transducer 1 point?
The relationship between scale factor and sensitivity of a transducer is scale factor is the inverse of the sensitivity
The scale factor is defined as the ratio between the original measurement and the new measurement.
If the scale factor is greater than 1, then the we are enlarging the measurement. If the scale factor is between 0 and 1, then we are shrinking the measurement
The sensitivity of the transducer is the output obtained per unit changes in the input. The higher sensitivity and lower sensitivity will lead to error. So the sensitivity should be moderate
Here the scale factor is inverse of the sensitivity, when the scale factor increases the sensitivity decreases
Therefore, the scale factor is the inverse of the sensitivity

the number of miles that a particular type of car can run before its battery wears out is exponentially distributed with an average of 20,000 miles. what is the probability that the car batery will die somewhere between 25000 and 30000 miles ? ( round to three decimal places )
So the probability that the car will die between 25000 and 30000 miles is P(X > 25000) = 0.286
How does probability work?Probability is a branch of mathematics that deals with numerical descriptions of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, generally speaking, 0 indicates the event's impossibility and 1 indicates its certainty.
Here,
Exponential distribution is memory less.
Let be the event of car number of miles car travels before dying out.
So mean
m = 20000
Now P(X > t) = [tex]e^{\frac{-t}{m} }[/tex]
Since P( X > [tex]\frac{(x+y)}{X > x}[/tex]) = P(X > y)
=> P(X > 25000) = [tex]e^{\frac{-25000}{20000} }[/tex]
=> P(X > 25000) = [tex]e^{\frac{-5}{4} }[/tex]
=> P(X > 25000) = 0.286
So the probability that the car will die between 25000 and 30000 miles is P(X > 25000) = 0.286

Keilantra spots an airplane on radar that is currently approaching in a straight line,
and that will fly directly overhead. The plane maintains a constant altitude of 7500
feet. Keilantra initially measures an angle of elevation ofa9° to the plane at point A. At some later time, she measures an angle of elevation of 34° to the plane at point B. Find the distance the plane traveled from point A to point B. Round your answer to
the nearest foot if necessary.
The distance between point A and point B is 36234 feet.
What is meaning of rounding to nearest feet?
Take a look at the straightforward process for rounding to the closest foot in the given points to become comfortable with the manual calculation:
Find the number of feet that is given first.
Look at the first digit following the decimal point, which is the digit we must round off.
If the value is in the range of 0 to 4, leave the digit we care about and trim the rightmost digits.
If the value is between 5 and 9, we should trim the rightmost portion of the number we care about and raise it.
The value that has been rounded to the closest foot is the final number.
Given that a plane maintains a constant altitude of 7500feet. Keilantra initially measures an angle of elevation of a 9° to the plane at point A. At some later time, she measures an angle of elevation of 34° to the plane at point B.
Assume that the position of Keilantra be X.
Draw a diagram that represent given situation.
Consider △ACX,
Applying tangent on the angle ∠AXC
tan 9° = AC/XC
tan 9° = 7500/XC
XC = 7500/ tan 9°
XC = 47353.13
Consider △XBD,
AC = BD = 7500
tan 34° = BD/XD
tan 34° = 7500/XD
XD = 7500/ tan 34°
XD = 11119.20
From the diagram,
AB = DC = XC - XD = 47353.13 - 11119.20 = 36233.92

The amount M (in trillions of dollars) of mortgage debt outstanding in the United States from 1990 through 2009 can be approximated by the function M = f(t) = 0.0037(t + 14.979)2, where t = 0 represents the year 1990.
a) Describe the transformation of the common function f(x) = x2. Then sketch the graph over the interval 0 ≤ t ≤ 19.
b) Predict the mortgage debt in the year 2014.
Answer:
The function f(t) = 0.0037(t + 14.979)^2 can be rewritten as f(t) = 0.0037(t^2 + 29.958t + 222.126). This is a quadratic function that has been stretched vertically by a factor of 0.0037 and shifted 14.979 units to the right and 222.126 units up.
To sketch the graph of this function, we can start with the graph of f(t) = t^2, which is a parabola that opens upwards. The transformation of this function stretches the parabola vertically by a factor of 0.0037, so its maximum and minimum values will be much smaller. The shift of 14.979 units to the right means that the vertex of the parabola will be located 14.979 units to the right of the vertex of the original parabola. The shift of 222.126 units up means that the minimum value of the function will be located 222.126 units above the minimum value of the original parabola.
On the interval 0 ≤ t ≤ 19, the graph of the function will be a parabola that stretches vertically by a factor of 0.0037 and is shifted 14.979 units to the right and 222.126 units up from the graph of f(t) = t^2.
To predict the mortgage debt in the year 2014, we can substitute t = 24 into the function f(t) = 0.0037(t + 14.979)^2. This gives us f(24) = 0.0037(24 + 14.979)^2 = 0.0037(39.979)^2 = 0.0037 * 1595.7441 = 5.90834 trillion dollars. This is the predicted mortgage debt in the year 2014.
