Answer:

Step-by-step explanation:
Standard form of a sine or cosine function,
y = acos(b(x+c))
where a is the amplitude, b is the value to find the period. and c is the phase shift.
Period = \frac{2\pi}{b}
From the equation given in the question,
[tex]y = 3cos(8\pi \: t + \frac{\pi}{2} ) \\ y = 3cos(8\pi(t + \frac{1}{16} )) \: \: (factorising \: 8\pi \: out)[/tex]
We can see:
Amplitude = 3,
Period = \frac{2\pi}{8\pi} = 1 / 4
Phase Shift = 1 / 16
Now we want to find the frequency.
Frequency = 1 / Period
= 1 / (1/4)
= 4Hz
Answer:
[tex]\displaystyle 4[/tex]
Step-by-step explanation:
[tex]\displaystyle y = Acos(Bx - C) + D[/tex]
When working with a trigonometric equation like this, always remember the information below:
[tex]\displaystyle Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A|[/tex]
So, the first procedure is to find the period of this graph, and when calculated, you should arrive at this:
[tex]\displaystyle \boxed{\frac{1}{4}} = \frac{2}{8\pi}\pi[/tex]
You will then plug this into the frequency formula, [tex]\displaystyle T^{-1} = F.[/tex] Look below:
[tex]\displaystyle \frac{1}{4}^{-1} = F \\ \\ \boxed{4 = F}[/tex]
Therefore, the frequency of motion is four hertz.

Lowest score earned to be qualified for an interview is 92.82

X ~ N(80,100)
Here we need to find x such that P(X > x) = 0.10
using standard normal table,
we get P( z > 1.282) = 0.10
It's always easy to use Standard normal distribution to solve questions of normal distribution because standard normal is special case of normal distribution with mean 0 and standard deviation 1.
To convert x (which follows Normal distribution) to standard normal use: [tex]\frac{x-\mu}{\sigma} \sim N(0,1)[/tex]
so, [tex]z = 1.282 = \frac{x-\mu}{\sigma}[/tex]
hence,
[tex]x = 1.282 * \sigma + \mu \\x = 1.282 * 10+_80 \\x = 92.82 \\[/tex]

0.5(4x - 8) = 2x + 5
There is no value of x that makes the equation 0.5(4x - 8) = 2x + 5 true. The solution is "no solution."
To solve for the value of x in the equation 0.5(4x - 8) = 2x + 5, follow these steps:
Step 1: Distribute the 0.5 on the left side of the equation:
0.5 * 4x - 0.5 * 8 = 2x + 5
Simplify:
2x - 4 = 2x + 5
Step 2: To isolate the variable term "x" on one side of the equation, move the constant terms to the other side. In this case, subtract 2x from both sides:
2x - 2x - 4 = 2x - 2x + 5
Simplify:
-4 = 5
Step 3: The equation simplifies to -4 = 5, which is not true. This means that the equation has no solution, and there is no value of x that satisfies the equation.
Therefore, there is no value of x that makes the equation 0.5(4x - 8) = 2x + 5 true. The solution is "no solution."

A post office always charges a flat one-time fee for any order. One time, Michael sent 35 letters and paid $26.00. The next time, he sent 18 letters and paid $14.10. How much does the post office charge to send one letter? What is the flat fee?
Answer:
$0.70 per letter, $1.50 flat fee
Step-by-step explanation:
Let x be the flat fee.
Let y be the cost of sending 1 letter.
Lets create 2 equations from those 2 instances.
First Instance: x + 35y = 26 - Equation 1
Second Instance: x + 18y = 14.1 - Equation 2
To find x and y , we can use elimination method in solving simultaneous equations.
Equation 1 - Equation 2
x - x + 35y - 18y = 26 - 14.1
17y = 11.9
y = [tex]\frac{11.9}{17} \\[/tex]
= $0.70
Now we substitute y into equation 1.
x + 35(0.70) = 26
x + 24.50 = 26
x = 26 - 24.50
= $1.50
From the above we know the post charges $0.70 per letter sent and charges $1.50 flat fee.

Solve the system of equations. 5x y = 9 3x 2y = 4 (−2, 5) (1, 4) (2, −1) (4, −4)
The solution of the system of equations that is given is (2,-1).
Given a system of equations are 5x+y=9 and 3x+2y=4.
A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables. A solution to a linear system is an assignment of values to the variables such that all the equations are simultaneously satisfied.
The given equations are
5x+y=9 ......(1)
3x+2y=4 ......(2)
Here, the substitution method is used to solve the system of equations.
Find the value of y from equation (1) by subtracting 5x from both sides.
5x+y-5x=9-5x
y=9-5x
To find the value of x substitute the value of y in equation (2).
3x+2(9-5x)=4
Apply the distributive property a(b+c)=ab+ac as
3x+2×9-2×5x=4
3x+18-10x=4
Combine the like terms on the left side as
-7x+18=4
Subtract 18 from both sides and get
-7x+18-18=4-18
-7x=-14
Divide both sides by -7 and get
(-7x)÷(-7)=(-14)÷(-7)
x=2
Substitute the value of x in equation (1) and get
5(2)+y=9
10+y=9
Subtract 10 from both sides
10+y-10=9-10
y=-1
Hence, the solution of system of equations 5x+y=9 and 3x+2y=4 is (2,-1).

What is the solution to f(x) = g(x) if f(x) = 2x+24 and g(x) = 5(0.5)^x
We can solve this graphically, we will see that f(x) = g(x) when x = -2, so the solution is x = -2.
How to solve the system of equations?
We want to solve the system:
f(x) = g(x)
Where:
[tex]f(x) = 2x + 24\\\\g(x) = 5*(0.5)^x[/tex]
Replacing the functions, we get:
[tex]2x + 24 = 5*(0.5)^x[/tex]
Notice that on the left side x is a coefficient, while on the right side, it is an exponent, so this is really hard to solve with algebra.
But what we can do, is graph both functions, and see for which value of x the graphs do intersect.
Below you can see the graphs, the green one is f(x), the blue one is g(x).

Step-by-step explanation:
First, the slope intercept for is y = mx+b. M is the slope, b is the y intercept. You know the slope is -7, so then just plug in the point for x, y and you'll get b = -58 once you cancel everything out.
So y = -7x-58.
For 27. just plug in the values. -3^3 is -27 * 3 which is -81 and then -12 and add 4 and you get -89.
