The speed of a wave is the product of the wavelength and its frequency.
The speed of the wave is 20m/s
Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
Hence, the speed of the wave is 20m/s

QUESTION 15
Answer:
yesss
Step-by-step explanation:
When Aidan had his picture taken, the photographer charged a $10 sitting fee and $6
for each sheet of pictures purchased.
a. Write a function for the situation.
b. State what x and y represent in the function.
c. Graph the function.
ASAP
Answer:
10y x 6x = y = sitting fee x = $6
Step-by-step explanation:
The function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the total charge is y and the number of the sheets is x.
So according to the problem:
y = 10 + 6x
Here y represents the total charge and x represents the number of sheets.
Thus, the function is y = 10 + 6x, where y represents the total charge and x represents the number of sheets.

Step-by-step explanation:
The candy produced by a company has a sugar level that is normally distributed with a mean of 16.8 grams and a standard deviation of 0.7 grams. The company takes readings of every 10th bar off the production line. The reading points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4. Is the process in control or out of control and why?
Answer:
It is not in control because at least two of the of the data points are more than 2 standard deviations from the mean are far apart.
18.3,18.4 > 18.2 Upper Control limit
14.9, > 15.4 Lower Control Limit
Step-by-step explanation:
Find the limits using μ ± 3σ and μ ± 2σ
Using μ ± 3σ
Upper Control Limit = μ + 3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9
Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7
Using μ ± 2σ
Upper Control Limit = μ + 2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2
Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4
The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.
Rearranging these data points 14.9, 16.1, 16.5, 17.3, 17.4, 18.3,18.4.
We see from the above that it is out of control because the values jump above and below the mean.
It is not in control as two of the of the data points are more than 2 standard deviations from the mean are far apart.

Which of the following best defines an input? (4 points)
a
An input is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.
b
An input is a special type of relation for which there is a rule that pairs each input with exactly one output.
c
An input is a set of ordered pairs in which no y-value repeats.
d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Answer:
d
Step-by-step explanation:
hope this helped!!!!!
Answer: d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Step-by-step explanation: Its d because the function has one output for each input so d is the correct answer.
I also saw the question on a different persons test in brainly and it was d.
Write an expression that represents the perimeter of triangle.
Combine like terms.
3.x
3x
15
Perimeter of triangle:
If the perimeter of the triangle is 90, what is the value of x?
The value of x is 12.5
A triangle has 3 sides: side A, side B and side C
Perimeter of a triangle = side A + side B + side C
Side A = 3x
Side B = 3x
Side C = 15
Perimeter of a triangle = 90
Perimeter of a triangle = side A + side B + side C
90 = 3x + 3x + 15
90 - 15 = 3x + 3x
75 = 6x
x = 75 / 6
x = 12 3/6
x = 12 1/2
= 12.5
x = 12.5

a circle has a diameter of 6 centimeters what is the approximate area of the circle
Answer:
28.26 [tex]cm^{2}[/tex]
Step-by-step explanation:
The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.
The formula for the area of a circle is: π[tex]r^{2}[/tex]
Plugging 3 into the radius, we have:
[tex]3^{2}[/tex] × π =
9 × π
We can round π to 3.14
9 × 3.14 = 28.26
