Modeling with sinusoidal functions
Hiro is riding a carousel that is next to a wall.
His horizontal distance C(t) (in m) away from the wall as a function of time t (in seconds) can be modeled by a
sinusoidal expression of the form a · cos(b. t) + d.
Att = 0, when he starts, he is closest to the wall, a distance of 2 m away. After 77 seconds he reaches his mid-
way point from the wall, which is 7 m away.
Find C(t).
t should be in radians.

Tell me everything you know about Pythagorean Theorem. Some things to include, but not limited to: Why is it that in some examples you have to subtract the square of a leg from the hypotenuse? Can this be used on every triangle? When might someone use this in real life as an adult?
Answer: Check below
Step-by-step explanation:
Okay so the Pythagorean Theorem was made by some old guy and the formula is a^2+b^2=c^2. You ALWAYS have to subtract the leg of the triangle when your finding a leg. You squareroot the square of the two legs if your finding the hypotnuse. The Theorem can be used to find any side of the triangle ONLY IF its a right triangle. An adult might use it in real life like when your an architect trying to find how much material you should use to make something thats in the shape of a right triangle.
Ps. Sorry if there's a bunch of grammar mistakes since this is kinda rushed

Find the coordinates of the intersection of the diagonals
of parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2). Hint: what do we know about
the diagonals of a parallelogram?
Answer:
We know the basic facts about parallelogram is The basic formula for calculating the area of a parallelogram is the length of one side times the height of the parallelogram to that side.
Step-by-step explanation:
The coordinates of the intersection of the diagonals of parallelogram XYZW is at (6, 4).
Parallelogram
A parallelogram is a quadrilateral in which opposite sides are parallel and equal. The diagonals of a parallelogram bisect each other.
Given parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2).
The equation of diagonal XZ is:
[tex]y-2=\frac{6-2}{10-2} (x-2)\\\\y=0.5x+1[/tex]The equation of diagonal YW is:
[tex]y-6=\frac{2-6}{9-3} (x-3)\\\\y=-\frac{2}{3} x+8[/tex]The point of intersection is at:
0.5x + 1 = (-2/3)x + 8
x = 6. Hence y = 4
The coordinates of the intersection of the diagonals of parallelogram XYZW is at (6, 4).

v2+4v-21=0 (solve by factoring)
Answer: (v + 7)(v -3)
Step-by-step explanation:
(v +7)(v -3)
v x v = v^2
v x -3 = -3v
7 x v = 7v
7 x -3 = -21
v^2 -3v +7v -21 = v^2 +4v -21 = 0
Answer:
The answer is (v - 3)(v + 7).
Step-by-step explanation:
First, you have to elaborate it :
v² + 4v - 21 = 0
v² - 3v + 7v - 21 = 0
Next, you have to collect like terms :
v(v - 3) + 7(v - 3) = 0
(v - 3)(v + 7) = 0
A student bought 3 boxes of pencils and 2 boxes of pens for $6. He then bought 2 boxes of pencils and 4 boxes of pens for $8. Find the cost of each box of pencils and each box of pens.
Answer:
.
Step-by-step explanation:
Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final

solve for X (3X+1) (10) (22) (7x-1)
Answer:
The value of x is 8
Step-by-step explanation:
In the given triangle
∵ A line segment joining points on two sides and parallel to the 3rd side
→ That means this line segment divided the two sides into equal ratios
∵ It divided the 1st side into 10 and 3x + 1
∵ It divided the 2nd side into 22 and 7x - 1
∴ [tex]\frac{10}{3x+1}[/tex] = [tex]\frac{22}{7x-1}[/tex]
→ By using cross multiplication
∵ 10(7x - 1) = 22(3x + 1)
∴ 10(7x) - 10(1) = 22(3x) + 22(1)
∴ 70x - 10 = 66x + 22
→ Subtract 66x from both sides
∵ 70x - 66x - 10 = 66x - 66x + 22
∴ 4x - 10 = 22
→ Add 10 to both sides
∴ 4x - 10 + 10 = 22 + 10
∴ 4x = 32
→ Divide both sides by 4
∴ x = 8
∴ The value of x is 8

What is the slope of the line parallel to y=2/5x-1?
I really need help with this fast please
Answer:
The slope will be 2/5.
Step-by-step explanation:
[tex]y = 2/5x -1[/tex] is written in slope-intercept form.
This formula looks like:
[tex]y=mx+b[/tex]
where:
M = Slope x = independent variableb = y-interceptSo:
[tex]2/5[/tex] is our slope[tex]x[/tex] remains our independent variable[tex]-1[/tex] is our y-intercept.1 ). For two lines to be parallel they must have the same slope.
Slope would remain 2/52 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.
. Slope would become -5/2As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.
Lets check our work!
Choose a random ordered pair. I will choose (5, 6).
Now, using point slope-form we can find out if what was said above is true!
This formula looks like:
[tex]y - y1 = m (x-x1)[/tex]
Let us substitute:
[tex]y - 6 = 2/5(x-5)[/tex]
Distribute:
[tex]y-6=2/5x-2[/tex]
Add 6 to both sides:
[tex]y= 2/5x+4[/tex]
Now using both equations I will plot them on a graph to see if they a parallel.
As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.
Based on all of the evidence, the slope will be 2/5.
Hope this helped! :)
