k/4+3=14
Move 3 over
k/4=11
Divide both sides by 4

Solve for k.
[tex]\displaystyle\frac{k}{4} +3=14}[/tex]
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]
First, subtract 3 on both sides:-
[tex]\dfrac{k}{4} =11[/tex]

Use the wave equation to find the speed of a wave given by y(x, t) = (2. 00 mm)[(20 m−1)x − (4. 0 s−1)t] 0. 5
The speed of the wave whose wave equation :
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] is 0.20 m/s
speed = 0.20 m/s
What is the speed of wave?
The wave equation is a linear second-order partial differential equation which describes the propagation of oscillations at a fixed speed in some quantity y.
The wave equation is given by:
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] .......................(1)
As we know that the standard form of wave equation is of the form is
On Comparing it with equation (1)
we have,
angular number, k=20
and, angular frequency, ω=4.0 rad/s.
Thus, the speed of the wave is
v=[tex]\frac{\omega}{K}[/tex]
=[tex]\frac{(4.0 rad/s) }{(20 m^{-1}) }[/tex]
=0.20 m/s
The speed of the wave of the wave equation
y(x,t) =[tex](2.00 mm)[(20 m^{-1} )x - (4.0 s^{-1} ) t]^{0.5}[/tex] is 0.20 m/s

What is the vertex of the quadratic function f(x) = (x-8)(x - 2)?
Answer:
The vertex is (5, -9).
Step-by-step explanation:
One way of approaching this problem consists of finding the roots. Seet the quadratic equal to zero and solve for x: {2, 8}.
The axis of symmetry is exactly halfway between 2 and 8: x = 5.
Now find the y-component of the vertex by evaluating f(5):
f(5) = (5 - 8)(5 - 2) = -9
The vertex is (5, -9). This is the minimum value of the function. The graph of this quadratic opens up.
round 7874 to 1 significant figure
7874
to find:7874 rounded to 1 sf
solution:if the previous digit is 5 or more round up, if not keep it as it is.
1 sf= 8000
therefore, 7874 rounded to 1 sf is 8000.
Answer:
8000
Step-by-step explanation:
Since the leftmost 7 is in the thousands place, you need to round the number to the nearest thousand. The digit to the right of the first 7 is an 8, so 7 goes up 1 to 8.
Answer: 8000

The slope of the line containing the points (-2, 3) and (-3,1) is
a.02 b.1/2 c.0 -2/5
Step-by-step explanation:
the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.
so, when going from (-2, 3) to (-3, 1)
x changes by -1 (from -2 to -3).
y changes by -2 (from 3 to 1).
therefore, the slope is
-2/-1 = 2/1 = 2

Describe the transformations necessary to transform the graph of f(x) into that of g(x).
Using translation concepts, it is found that the transformations necessary to transform the graph of f(x) into that of g(x) are given as follows:
Reflection over the y-axis. Horizontal stretch by a factor of 2.Shift left 3 units.Reflection over the x-axis.Shift down 1 unit.What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The original function f(x) is given by:
[tex]f(x) = \sqrt{x}[/tex]
The transformations are as follows:
Inside the domain, the function was multiplied by -1/2 and 3 was added. Hence the function was reflected over the y-axis, horizontally stretched by a factor of 2 and shifted left 3 units.Outside the domain, in the range, the function was multiplied by -1 and 1 was subtracted, hence the function was reflected over the x-axis and shifted down one unit.More can be learned about translation concepts at https://brainly.com/question/4521517

The equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
Let's suppose the equation that models the exponential decline is:

From the data given, we can calculate the value of a and b:
a = 46348587109809610
b = 0.9861
y = 46348587109809610(0.9861)ˣ
