Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0.
What are some examples of how exponential functions are employed in mathematics and in real life?Several real-world scenarios use exponential functions, including population increase, compound interest, radioactive decay, and the spread of diseases. For instance, an exponential function may be used to simulate the expansion of a bacterial population, with the rate of increase being proportional to the population size. Similarly, compound interest, which applies the rate of interest to the principal sum across a number of periods, can be represented by an exponential function.
Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0 and k translates the graph of f up when k > 0 and down when k < 0.

Answer:
Reflection
Step-by-step explanation:
With a reflection, a shape is mirrored across a line. So, while its position is changed, the points end up getting flipped too. In this problem, you can imagine a diagonal line goes right through the center of the two shapes shown (the original and its mirror). The line would be equidistant from L and G; it would be equidistant from B and D; it would also be equidistant from U and O. If you were to mirror B, U, and L across this line, you would get your reflection points D, O, and G.
The shape BUL is mirrored over a diagonal line to get DOG, which means it is a reflection
For each question, a) write an equation to represent the problem, b) list 3 solutions, then c) tell weather the graph would be continuous or discrete
ANSWER and EXPLANATION
We have that twice a number is increased by a different number and that is equal to 15.
a) Let the first number be x.
Let the second number be y.
This means that:
2x + y = 15
b) To find the possible numbers that can solve this, we have to pick random values of x, then use that to find the values of y.
Let us pick x as 3, 6 and 9.
When x = 3:
2(3) + y = 15
6 + y = 15
=> y = 15 - 6
y = 9
When x = 6:
2(6) + y = 15
12 + y = 15
y = 15 - 12
y = 3
When x = 9:
2(9) + y = 15
18 + y = 15
y = 15 - 18
y = -3
These are some possible solutions to the equation.
c) The graph of this equation would be continuous.
A continuous graph is one whereby x take any values not some particular values.
Because the question does not classify the kind of numbers, the numbers could be any numbers, and so, the graph would be continuous.

line passes through points (5, 8) and (10, 5). Line b is parallel to line a. what is the slope of line b??
Answer:
-3/5
Step-by-step explanation:
Let's go from the point (5, 8) to the point (10, 5). We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3. Thus, the slope of the line connecting these two points is m = rise/run = -3/5.
Both of these lines have the slope -3/5, given that they are parallel lines.

a ball is thrown upward in the air, and its height above the ground after seconds is feet. find the time when the ball will be traveling downward at feet per second. give your answer as a decimal approximation with at least 3 decimal places.
the ball will be traveling downward at a velocity of 24 feet per second after approximately 2.75 seconds.
What is velocity ?
Velocity can be defined as ratio of displacement and time taken.
To find the time when the ball will be traveling downward at a velocity of feet per second, we need to find the time when the velocity is equal to that value, which means the velocity is negative.
The velocity of the ball at any time t can be found by taking the derivative of the height function with respect to time:
v(t) = -32t + 64
We need to find the time t when v(t) = -24 feet per second. So we can set up the equation:
-32t + 64 = -24
Solving for t:
-32t = -88
t = 2.75 seconds (rounded to three decimal places)
Therefore, the ball will be traveling downward at a velocity of 24 feet per second after approximately 2.75 seconds.

The multiplicity of a root r of the characteristic equation of A is called the algebraic multiplicity of r as an eigenvalue of A. (true or false)
The multiplicity of a root r of the characteristic equation of A is called the algebraic multiplicity of r as an eigenvalue of A.
The above statement is True.
Eigenvalue:
An eigenvalue is a special set of scalar values associated with the most probable system of linear equations in a matrix equation. Eigenvectors are also called eigenvalues. It is a non-zero vector which can be modified by at most its scalar factor after applying a linear transformation.
According to the Question:
If the geometric multiple of the eigenvalues is greater than or equal to 2, the linearly independent set of eigenvectors is no longer unique to the multiple as before. For example, for the diagonal matrix A=[3003], one could also choose the eigenvectors [11] and [1−1], or any pair of two linearly independent vectors.
Sometimes vectors are simply expanded to vector times matrix. If this happens, this vector is called the eigenvector of the matrix and the "stretch factor" is called the eigenvalue. Example: Given a square matrix A, λ is the eigenvalue of A, and the corresponding eigenvector x is

Find the length of the
missing side of the triangle
to the nearest tenth.
Answer: 15
Step-by-step explanation:
For this question you have to use pythagoras' theorem.
Pythagoras' theorem is c²=a²+b²
So c is the hypotenuse and the hypotenuse is always opposite the right angle.
So the equation would be c²=9²+12²
Then 9²=81 and 12²=144
So the equation would then be c²=81+144
So c²=225
Then you just want to find c on it's own so you have to square root it which is 15.
Which equation represents exponential decay?
a) y=0.5x3
b) y=0.5x2 - x
c) y=0.5(1.07) dy=0.5(0.87)*
Find the dot product v. w. =v-10i 9j. w --4i-8j A) -72
B) -40 C) -112 D) 32
To find the dot product between vectors v and w, we need to multiply the corresponding components of the vectors and then sum up the results. Given that v = -10i + 9j and w = -4i - 8j, let's calculate the dot product:
v · w = (-10)(-4) + (9)(-8)
= 40 - 72
= -32
Therefore, the dot product between vectors v and w is -32.
None of the provided answer choices (-72, -40, -112, 32) match the calculated value of -32. It's possible that there may be a mistake in the answer choices or the values given for vectors v and w. Please double-check the values and answer choices provided to ensure accuracy.

Alex drives at an average speed that is 1/6 of the average speed that Roy's train travels. Alex takes 20 minutes to travel 12 km in her car. Roy travels for 2 hours and 20 minutes on his train. How far does Roy travel to 2 dp?
Answer: 336.00 km distance of train
Step-by-step explanation:
Alex = 20mins =12km We distribute to 1hr to find 60mins = 36km p/h.
Roy = 2hrs 20 mins and is 4x the speed of the car.
So 36km x 4 p/h = 144km p/h
2hrs and 20 = 144 x 2.3333 = 335.9952 = 336km
What are the equations of lines m and q?
The equation of line m is:
Answer:
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]
Step-by-step explanation:
To find the equation for both 'm' and 'q' requires a bit of work. Because neither 'm' nor 'q' has two points to find the slopes of the line, we have to get creative.
Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. Luckily for us, line 'n' is parallel with 'q' and perpendicular with m.
Finding the slope of 'n'
The slope of the 'n' = (y₂ - y₁) ÷ (x₂ - x₁)
= (4 - (- 1)) ÷ (4 - 1)
= 5 ÷ 3
= ⁵/₃
Determine the slope of 'q' and 'm'
When two lines are parallel, they have the same slope.Since 'n' and 'q' are parallel,
then the slope of q = ⁵/₃
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.Since 'n' and 'm' are perpendicular
then the slope of m = - ³/₅
Write the equation for 'q' and 'm'
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines
For both 'q' and 'm' let (x₁, y₁) be (2, 6)
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]

uppose v,w∈r3are orthogonal unit vectors. let u=v×w. show that w=u×v and v=w×u.
To show that w = u × v and v = w × u, we need to demonstrate that the cross product of vectors u and v yields the same result as the cross product of vectors w and u.
Given that u = v × w, let's calculate the cross product of w and u:
w × u = (u × v) × u
Since the cross product is not associative, we need to use the vector triple product identity:
w × u = u × (v × u) - (u · u) v
Since u is orthogonal to v, the dot product (u · v) is zero. Therefore, we can simplify the equation:
w × u = u × (v × u)
Next, let's calculate the cross product of v and u:
v × u = (u × v) × v
Using the vector triple product identity:
v × u = v × (u × v) + (v · v) u
Again, since u is orthogonal to v, the dot product (v · v) is zero:
v × u = v × (u × v)
Thus, we have shown that w = u × v and v = w × u, indicating that the cross products are equivalent in both directions.
In summary, when u, v, and w are orthogonal unit vectors, the cross product of u and v yields the same result as the cross product of w and u, as well as the cross product of v and w.
