Answer:
Step-by-step explanation:
The standard form for this function is
y = Asin(Bx - C) + D where
A is the amplitude,
B is used to find the period in the formula [tex]period=\frac{2\pi}{B}[/tex],
C is used to find the phase shift in the formula [tex]ps=\frac{C}{B}[/tex],
and D is the midline which either moves the function up or down from its natural midline of 0.
We have no given phase shift, so there is no C value. The amplitude is easy; we just fill in A as 4. The period is another story:
[tex]\frac{3\pi}{2} =\frac{2\pi}{B}[/tex] and we solve for B by cross multiplying:
3πB = 4π and
[tex]B=\frac{4\pi}{3\pi}[/tex] so
[tex]B = \frac{4}{3}[/tex] so the function is
[tex]y=4sin(\frac{4}{3}x)+5[/tex]
You get a gift of $1,000. You decide that you want to invest all of the money in a savings account. However, your bank has two different savings plans. Determine the final amount in the account for each plan in 5 years. Round your answers to two decimal places if needed.
Plan A: The bank gives you 4% interest rate and it is compounded every two months.
Plan B: The bank gives you a 10% interest rate and compounds the interest every 6 months.
Final Account balance for Plan A: $
Final Account balance for Plan B: $
Step-by-step explanation:
write what you know
P = 1,000
n = 5 years
Plan 1
i = 0.04 / 2 months = (0.04 / 2 months) x (12 months / year) = 24%
write and solve
future value = p(1+i)^n = 1000(1+0.24)^5
plan 2
i = 0.10 / 6 months = (0.10 / 6 months) x (12 months / year) = 20%
write and solve
future value = p(1+i)^n = 1000(1+0.20)^5

Given parallelogram ABCD, find x, y, length AB and Length BC.
Answer:
x = 18 y = 5
Step-by-step explanation:
x + 5 = 2x - 13
x - 2x = -13 - 5
-x = -18
x = 18
2y - 2 = 4y - 12
2y - 4y = -12 + 2
-2y = -10|:(-2)
y = 5
Answer:
x = 18, y = 5, AB = 23, BC = 8
Step-by-step explanation:
The opposite sides of a parallelogram are equal, so
DC = AB , that is
2x - 13 = x + 5 ( subtract x from both sides )
x - 13 = 5 ( add 13 to both sides )
x = 18
and
BC = AD , that is
4y - 12 = 2y - 2 ( subtract 2y from both sides )
2y - 12 = - 2 ( add 12 to both sides )
2y = 10 ( divide both sides by 2 )
y = 5
Then
AB = x + 5 = 18 + 5 = 23
BC = 4y - 12 = 4(5) - 12 = 20 - 12 = 8
The kitchen, dining room, and living room of a house will be painted, each with a different color. There are 7 colors to choose from. This means that there are _[blank]_ color arrangements possible.
Answer:
21
Step-by-step explanation:
Given that :
Number of rooms = 3
Variants of paint available = 7
Since the rooms will be painted with different colors :
Hence,
Number of possible paintings for kitchen = 7 (7 different paints)
This also applies to the other 2 rooms
Hence,
We have 3 * 7 = 21 color arrangements possible.

question: write an expression for the transformation of f(x), given the following graph
i have many points, must provide real answer or you will be reported
Answer:
f(x+3) +7
Step-by-step explanation:
We move the green graph 3 units to the left f(x-h) where h is how many units moved. We are moving 3 units to the left so h is -3 f(x - -3)
f(x) becomes f(x+3)
Then we move up 7 units
f(x) +k where k is the number of units up or down
f(x+3) +7

Multiply the whole equation by 2
[tex]2*12(4x -5) + \frac{5}{2}*2=10*2\\\\24(4x-5) + 2 = 20\\[/tex]

Answers:
x = 7Area of shaded region = 162 square unitsYou may need to leave off the "square units" portion.
=============================================
Explanation:
For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.
L = 3x
W = x+5
The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.
P = 2(L+W)
2(L+W) = P
2(3x+x+5) = 66
2(4x+5) = 66
8x+10 = 66
8x = 66-10
8x = 56
x = 56/8
x = 7
-------------------
Now that we know x, we can find the area of the rectangles.
As you probably can guess, the shaded region is the difference of the two areas.
A = area of larger rectangle
A = (length)*(width)
A = (3x)*(x+5)
A = (3*7)*(7+5)
A = 252
B = area of smaller rectangle
B = (x+3)*(x+2)
B = (7+3)*(7+2)
B = 90
C = area of shaded region
C = A - B
C = 252 - 90
C = 162 square units is the area of the shaded region.

4.Beyunka is creating a diagram to prove that a certain triangle is a right triangle.
In her diagram, she uses three white quadrilaterals that are squares. Which
diagram could be the one that Beyunka is creating?
Option 'D' is the correct option.
The correct diagram for Beyunka creating is given in option D.
What is Right triangle?
When an angle of a triangle is measure 90 degree then the triangle is called a right triangle.
Given that;
Beyunka is creating a diagram to prove that certain triangle is a right triangle.
Since, The right triangle is satisfy the Pythagoras theorem.
Now, By option D;
Let sides of a triangle are,
Hypotenuse (H) = c
Perpendicular side (P) = a
Then, The base of the right triangle = √H² - P² = √c² - a²
And, All other diagrams are not satisfy the Pythagoras theorem.
Thus, The correct diagram for Beyunka creating is given in option D.

Answer:
x = 2, P = 22 cm, A = 21 cm²
Step-by-step explanation:
The 2 legs of the triangle are congruent , then
6x - 4 = 8 ( add 4 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
perimeter = 8 + 8 + 6 = 22 cm
Area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 6 and h = 7 , then
A = [tex]\frac{1}{2}[/tex] × 6 × 7 = 3 × 7 = 21 cm²
Answer:
x = 2
Perimeter = 22 cm
Area = 21 cm²
Step-by-step explanation:
=> We know that the 2 side lengths of the given triangle are congruent, because of the congruency mark theorems, therefore to solve for x first, we can say;
6x - 4 = 8
6x = 8 + 4
6x = 12
x = 12/6
x = 2
Now that we know the side lengths of the triangles are 8, 8 and 6, we can find the perimeter;
Side 1 + Side 2 + Side 3 = Perimeter
8 + 8 + 6 = Perimeter
22 = Perimeter
Lastly to find the Area of the triangle, follow the formula of;
A = 1/2 (b * h)
A = 1/2 (6 * 7)
A = 1/2 (42)
Area = 21
Hope this helps!
