Answer:
f(x) = 5*cos(5*x) + 2
Step-by-step explanation:
A general cosine function is written as:
f(x) = A*cos(ω*x) + M
where:
A is the amplitude
M is the midline
ω is the angular frequency.
In this case we know that:
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is 2*pi/5
The relation between the angular frequency ω and the period T is:
ω = 2*pi/T
Then if the period is T = 2*pi/5, replacing that in the above equation we find that:
ω = 2*pi/T = 2*pi/(2*pi/5) = 5
ω = 5
Then the function is:
f(x) = 5*cos(5*x) + 2
The cosine function should be [tex]f(x) = 5\times cos(5\times x) + 2[/tex]
The calculation is as follows:
A general cosine function is written as:
[tex]f(x) = A\times cos(\omega\times x) + M[/tex]
where
A is the amplitude
M is the midline
ω is the angular frequency.
Here, in the given situation
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is [tex]2\times \pi\div 5[/tex]
The relation between the angular frequency ω and the period T is:
[tex]\omega = 2\times \pi\div T[/tex]
Now Then if the period is [tex]T = 2\div \pi\div 5,[/tex] replacing that in the above equation we find that:
[tex]\omega = 2\times \pi\div T = 2\times \pi\div (2\times \pi\div 5) = 5[/tex]
ω = 5
Then the function is [tex]f(x) = 5\times cos(5\times x) + 2[/tex]

Solve for X
explain the process for this problem
Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

-5. -5
-2x=7 so ans shld be -2x=7
Answer:
-2x = 7
Step-by-step explanation:
Problem to solve:
5 - 2x = 12
Step 1:
We need to isolate the dependent variable x, we can do that by subtracting 5 from both sides of the equation.
=
-2x = 7
Step 2: (to find x)
Divide both sides of the equation by -2
=
[tex]x = -\frac{7}{2}[/tex]

Calculate the midpoint of the line segment with endpoints A(− 4, −5) and B(2, 3).
The midpoint of the line segment is (-1, -1).
What is midpoint of a line segment?The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
It is obtained by averaging the x-coordinates and averaging the y-coordinates of the endpoints of the segment.
Given endpoints
A(− 4, −5) and B(2, 3)
Midpoint of the line segment formula:
Midpoint of a Line Segment : Its x value is halfway between the two x values · Its y value is halfway between the two y values.
Midpoint [tex]= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2})[/tex]
Midpoint = [tex](\frac{-4+2}{2} ,\frac{-5+3}{2} )[/tex]
Midpoint = [tex](\frac{-2}{2}, \frac{-2}{2} )[/tex]

Answer:
Hello! answer: 268
Step-by-step explanation:
When doing these you want to find each face separately then add them up so here are all the faces... 24 + 24 + 80 + 80 + 30 + 30 = 268 so 268 is our surface area! Hope this helps!
Answer:
268 cm²
Step-by-step explanation:
Surface area: The sum of all the areas of every side of the prism.
As a shortcut, you can find the three unique sides and multiply the number by 2 (because opposite sides of a rectangular prism are the same)
Find the surface area of:
8 by 10 side: 8 * 10 = 80
3 by 8 side: 3 * 8 = 24
3 by 10 side: 3 * 10 = 30
Add these measures together.
80 + 24 + 30 = 134
Multiply this number by 134.
134 * 2 = 268
Thus, the answer is 268 cm²

A quantity with an initial value of 9700 grows continuously at a rate of 0.65% per hour. What is the value of the quantity after 2.75 days, to the nearest hundredth?
Answer:
.65% / hr = .0065 / hr
2.75 days * 24 hrs / day = 66 hrs
66 hrs * .0065 / hr = .429
So our amount will become
A = A0 ( 1 + .429) = 9700 * 1.429 = 13860

Answer:
36
Step-by-step explanation:
for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this
1^3 + 2^3 + 3^3
or expanded out
(1x1x1)+(2x2x2)+(3x3x3)
Solving that down, the equation turns into this
1 + 8 + 27
Adding those values together leaves us with 36!
Hope this helped, have a good rest of your day!
Answer:
36
Step-by-step explanation:
[tex]1^{3}[/tex] + [tex]2^{3}[/tex] +[tex]3^{3}[/tex] = 36
[tex]1^{3}[/tex] = 1 x 1 (= 1) x 1 = 1
[tex]2^{3}[/tex] = 2 x 2 (= 4) x 2 = 8
[tex]3^{3}[/tex] = 3 x 3 (= 9) x 3 = 27
27 + 8 + 1 = 36

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.
What is the length of the rectangle?
0.75 units
1.5 units
3 units
6 units
Answer:
6 units
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
A rectangle’s width is one-fourth of its length.
W = 1/4 × L
W = L/4
Cross Multiply
L = 4W
A = 9 square units
Hence
9 = L × W
We substitute 4W for L
9 = 4W × W
9 = 4W²
We square root both side
√9 = √4W²
3 = 2W
W = 3/2
W = 1 1/2 unit or 1.5 units
Solving for L = Length
9 = L × W
9 = L × 1.5
L = 9/1.5
L = 6 units
Therefore, the Length of the rectangle = 6 units
